Don't Plant Seeds


These are not seeds.  Plant these.
Seeds suck.  More on this in a moment- here is some context...

With a few sunny days in Missoula, it seems that everyone's thoughts have turned from ice fishing to the garden (well maybe that is just me).  Anyway, the point is that people are eager to get out in the garden, and early March warm days often fool us into thinking spring is here.  Indeed signs of spring abound.  The first sagebrush buttercups began flowering in our front yard prairie yesterday.  You know what I say about sagebrush buttercups, "someone's got to be first".

Now is a great time to finalize your plans for the garden (and soon, I'll post my list of garden projects, as I do each year at some point).

So, back to the title, some advice for your native plant gardeners out there-  don’t plant seeds, they suck. This is the second in my “things that suck” series.  I am still getting hate mail from my first article in the things that suck series- "Honeybees suck".  However, it seems like people have now embraced the idea that native pollinators can do things that honeybees can't. But I digress.

And I am clearly exaggerating.  Seeds don't suck.  Obviously, seeds have their place and for most plants that is where it all begins. However, when embarking on a new native plant garden don’t plant seeds, at least not in the ground (read on).

My wife and I are garden coaches- we help people garden and in most cases, people come to us because of what they have tried, and failed, and in many of these instances they are disillusioned by the promise of native plants. Like any sort of landscaping site preparation is critical. Unfortunately this not the fun part that everyone looks forward to, but it is definitely the most important part. More than anything else, site preparation at the beginning of your garden will dictate success or guarantee failure.

We always recommend diligent site prep (that people inevitably want to cut corners on), planting container stock, and mulching heavily to retain moisture and keep weeds at bay. We usually recommend some combination of a ground cover (like newspaper or cardboard, and shredded bark mulch or composted mulch (aka "soil pep"). All these things will eventually break down over time but they allow plants to get established and keep weeds down.

The Lure: Seeds are cheap and seem like and easy way to go.
I've fallen victim to this too. Promise and hope of seeds springs eternal. We have some raised planting beds in our alley that we have periodically used for different things. Overtime, I have let them go (out of site, out of mind. Last year I figured I’d stop ignoring them and replant them with a variety of tough (read: able to withstand the neglect I would inevitably inflict on them) native plants. I dug out all the weeds, turned the soil over, and let whatever was there germinate. Then, I repeated the process, and the bed was ready to plant.

That is when I came across a packet of a “native” wildflower seed mix a local native plant nursery gave me (about 10 species, one of which isn’t even native to Montana- see below). When I got them, I had no intention of planting them, and just filed them away, but here they were again. So now, looking for something to plant, I figured "what the heck" I’ll try these (ignoring everything I tell people). So I sowed the seeds, watered them and a few days later came out to investigate- sure enough, lots of germinants- everywhere. Success?
Who knows?
I had no idea what was coming up. I gave it some more water, and watched some things grow. But what were they? Was I nurturing alley weeds? At that point I figured I’d learned my lesson, and dug it all up and planted some plants I transplanted from other areas of my garden (see photo at the beginning of the post).

They are doing great now by the way.

If I had a nickel for everyone that said that they threw some seeds down (usually lawn or weedy place), and nothing came up- the seeds didn’t work, I’d have more money to buy a lot of seeds that I’d plant. IN POTS.  I would plant those seeds in pots where I could nurture and monitor them.

Here is another warning: never buy "wildflower" mixes, even if they are labeled "native."
  • They probably contain plants that are not native to your area (or country)
  • The seeds have vastly different germination requirements
  • They probably have a lot of filler- that is abundant seeds that have a super low germination rate 
  • They might even contain plants that don’t have the same water requirements.
Identify what species you want, learn their habits (how big they get, if they are palatable to deer, sun, shade and water use, soil preferences, germination success rates, etc…) and buys seeds of species you have selected.

Think about these issues before planting seeds directly into the garden:
  • It is difficult to identify cotyledons (the seed leaves) or the seedlings. Many look identical.
  • Because they are seeds, you can’t mulch them- this would inhibit their growth (which is what mulch is designed to do). As result, a lot of other things will germinate, and unless you live near a beautiful native plant paradise, the source for the seeds will likely be things that you don’t want or may inevitably undermine your garden 
  • Germination rates vary widely among species.
  • Some plants have a 1% germination rate, and some have nearly 100% (but you might not what this ratio of plants- for examples, see my many posts about bluebunch wheatgrass in out front yard!)
  • Methods for germination vary by species and can be very complex. For example some plants require a 3 moth cold period, some require scarification (physically damaging the seed husk), some need to be buried, etc…). Although this might seem overwhelming and confusing, this is really cool and you can begin to learn about all the adaptations plants have to different habitats and co evolution with herbivores, local climates, available precipitation, natural disturbance events etc…

When should you directly seed?
  • When you have the ability to control weed seeds
    • For example, if you are sowing grasses,  you can use a broad leaf herbicide if your likely weeds are going be broad leaf plants. 
    • But if the expected weed is another grass (cheat grass, quackgrass, Kentucky bluegrass), you should rethink!
    • If you are covering a vast area- like acres.
  • If you are surrounded by similar native plants 
    • Like in a restoration project with adjacent intact communities. 
  • If you are planting a specific species that can only be grown in place via seeds
    • That is, a species that doesn’t transplant well (like arrow leaf balsamroot), 
    • or the soil conditions preclude transplanting (like VERY rocky soil- as in bedrock).
So what about seeds?
Buy them, learn how to germinate them, and plant them in pots or flats that are well labeled. Take pictures of the germinants so you can identify them in the future. Take notes on what works and what doesn’t. Invest in a seeding heat mat, and self-watering seedling trays. Learn about rooting medium.

This is a really fun and rewarding part of gardening and you will learn a lot. Consider how when and why plants have adapted to germinating the way they do. Consider how they are dispersed, eaten, etc… and you will learn a lot more about the natural work and the ecosystems they live- and the other animals that depend on them. But whatever you do, don’t throw seeds on the ground and expect anything else but throwing your money away.

The best resource for learning how to grow Montana native plants (many of which are also native across a wide portion of the intermountain west) is by getting a copy off Sheila Morrison’s book "The Magic of Montana Native Plants". And the best place to get native wildflower seeds from knowledgeable people is Native Ideals Seed Company in Arlee.  You can find Bryce and Rebecca at local markets and fairs, or online.

But once you buy those seeds, plant them in pots!

How to remove a lawn; part 2

Spring is coming and I know a lot of people are thinking about expanding or planting a native plant garden. Inevitably the first question is about site preparation and, specifically what to do with the lawn that is between them and their wildlife and native plant garden destiny.

How to remove a lawn is by far the most often searched phrase that leads people to my blog, and that post (titled the same) is far and away my most viewed page.

I thought I’d update the post with some more information and details based on questions I receive on this blog, in my speaking engagements and from mine and my wife’s native plant, wildlife and sustainable garden coaching business, Butterfly Properties (yes, my last name is German for "butterfly").

Like painting a house or so many other things, success is only guaranteed by the mundane tasks of preparation.  Site preparation is the inglorious hard work that is the most important part, but often the part that gets short cut.  And what is true for painting a house is true for gardening and native plant landscaping.  Frustration, failure, dissatisfaction or disillusionment can often be traced back to skipping steps and taking short cuts in site preparation.  In gardening terms, specifically in a native plant garden  that comes down to getting rid of the existing lawn and keeping it out.

In defense of the sod cutter. 
Sod cutters are hard to use, they are loud, they run on gas, and they are the best tool for the job.
Although meticulously removing sod is always my suggestion, I am always met with questions where people would like an alternative.  An alternative that many perceive is easier, more earth friendly, cheaper, quicker, etc...  around here (Missoula) for the last few years, "lasagna" gardens or sheet mulching has become very popular.  Initially popular, that is, it becomes very unpopular when people have to remove it, or deal with weeds in the lasagna.  Typically what leads to failure is not giving the lasagna garden time enough to work, not dealing with the existing weeds, our climate, or a combination of the three.
The idea of a lasagna garden is a nice one, and one that should be left for the idea book. A lasagna garden can work, I know, but I don't recommend it.

In my blog (and in our garden coaching business) I advocate for physically removing the lawn and I still do.  This is the thing most people are resistant to do, but I think it is still the best and most effective way.  It is also the quickest, and depending on you method, it could be the least resource intensive.  You can dig it all up with a hand sod lifter or even a square bladed shovel and then compost it on site- This has to be one of  the most, if not the most, resource un-intensive methods for lawn removal.

Composting the sod does take time and a lot of space (depending on the quantity of sod you are removing).  Also if you are going to go this route, dry the sod out (under a tarp or something and them screen the soil off  first. 

The inevitable questions:
What about solarizing? Using cardboard?  Using a rototiller? Turning the sod upside down?
There is always someone that will say it worked for them, but there are probably three other people out there that have a different experience.  We have removed a lot of lawn, and the sod cutter (in one form or another) is always our method. My wife and I have landscaped public areas, little parks (like the Native Plant Garden at 8th and Grant), and other places that get very little maintenance, and the essential steps to ensuring that the areas stay weed free are below.

The typical steps (from How to Remove a Lawn):

  1. remove the sod
  2. remove any weeds the sod cutter missed
  3. wait a little while to see what germinates or grows back than remove that, too.  
  4. cover soil with newspaper or cardboard
  5. apply mulch
  6. plant


Although I provide more detail on other aspects of lawn removal here, these are some questions 

Is it hard to use a sod cutter?  Yes.  It takes work, depending on your soil (or lack of soil, like in many Missoula yards) it can be a beast of a job.  I am not saying don’t do it, just be prepared. One of the biggest mistakes people make is removing too much soil, and this leads to a lot of extra work.  
It is critical to set the sod cutter at the proper depth- you don’t want to remove perfectly good soil, just get below the rooting depth of the grass. 
Although you can plant right away, it's better to wait and see what comes up. But don’t wait too long, because you will be inviting anything and everything from germinating.

Is lawn edging necessary?
Yes, unless you really enjoyed removing the sod and want to keep doing it for years to come. 
Edging is very effective, if installed correctly.  Buy the biggest (deepest) kind possible.  Aesthetically, metal edgings looks the best, steel or aluminum.  Metal edging has the smallest profile and creates a nice clean look. Although I like steel the best, it is the most expensive and the hardest to work with.  For most homeowners, I suggest plastic edging.  The main criticism with plastic edging is from when it is improperly installed and it sits up too high.  This is a problem for a several reasons.  First, aesthetically, it is ugly.  Second, if it is too high, it can work its way out of the ground through the freeze/ thaw cycle.  Third it is ugly.  Fourth, if it is set too high, it may allow rhizomes and runners to get underneath and invade the lawn-less area.    Did I mention that if you set it too, high it is ugly?  Just set the edging so it is just proud of the surface of the soil.  If installed correctly, you shouldn't really notice it.

One great source for lawn edging in Missoula is at Home ReSource.  It always seems like they have some there and it is a great thing to re-use.

The final suggestion is about the size of the project.  This is another thing that can lead to disillusionment.  Only remove what you can plant in the near future (could be a week or season, depending on your time and goals)- don’t embark on too big of a project.  I'd rather someone gets satisfied completing a small project and has inspiration to continue, instead of attempting something too large and being overwhelmed by trying to do too much. Unfortunately, the only way to know what is too big or too small is to try.
Having said all that, another mistake is not building beds big enough!  Decide how big a bed you think you need, draw it out, wait a little while, than double it.  No one ever says "I wish I had more lawn” when they are removing some. 

The good news is, like with more gardening projects, you can add more later (or remove more lawn that is).

Native Plant Gardening Events June 25 & 26


Next weekend my wife and I are organizing two native plant and wildlife gardening workshops/ events.  The first would help us complete a portion of the landscaping at Home ReSource (my favorite Missoula store), and the second is some maintenance work at the Native Plant Garden at 8th and Grant (pictured above).

My wife and I have a native plant, wildlife, and sustainable garden coaching and consultation business, Butterfly Properties, and each year we select a community project to work on as volunteers.  We enjoy spreading the beauty of native plants throughout town, and promoting an appreciation of Montana's flora.  The Native Plant Garden at 8th and Grant and Home ReSource's landscaping are two of our on-going projects.


We also support non-profits in other ways: offering discounted services to the Green Blocks participants, donating services to charity auctions, even giving actual money when we have it (we are even in the process of devleoping a grant program for community groups and non-profits).


We're planning some work at both these sites next weekend and we hope you will join us for a few hours and learn about landscaping installation, site preparation, design, and of course, weeding.

Saturday June 25, 10 am- 1 pm at Home ReSource, 1515 Wyoming Street

We are finishing the Home ReSource project by adding a "landscape pocket" on the Russell Street side. This new bed is an opportunity to learn about site preparation, native plant species, and garden maintenance. We love Home ReSource (their mission, their staff, and all the cool stuff they have for sale), and we have been donating our time and materials to this site since last year. (Here's a blog post from several months ago about spring maintenance in the HR gardens).

Topics/ activities:
Site preparation (when do you need to add topsoil? Why? Where do you get it?
Soil grading (What is it? How?)
How to plant plants
Mulch (Why? How? Where do you get it?)
Tour established native plant landscape at Home ReSource (completed in 2010).
Weed identification and removal (minimal)

Bring work gloves, sturdy shoes and questions!

Sunday June 26, 6:30 pm - 8:00 pm at the Native Plant Garden at 8th and Grant


Stop by and check out how beautiful this little park has become, and see what's flowering this week! Help clean up the park and learn about native plants and wildlife gardening. We will be weeding, pruning and maybe even planting a few plants. Bring gloves, and tools for weeding (if you have them). You can learn more about the park here.

Maybe we'll throw a few horseshoes in the horseshoe court, if there's time and energy. It's a wonderful community spot and we'd love to show it to you. Sunday June 26th, 6:30 pm- 8 pm.

You can view and even RSVP for both of these events on our Facebook site

How to plant a plant

This is another installment of the “how to” series, which after reviewing some of the web statistics from my site are far and away the most popular.

This one sounds pretty basic and simple for a gardening blog, and at the risk of boring or offending some readers, I do think it is really important, not just knowing how to plant a plant, but why certain steps are done. This is intended for Montana native plants (planted in Montana), but for the most part is applicable to most others (expect things like orchids, hemi- parasites and saprophytes, I guess- you are on your own there).
  • Locate utilities (plan to do this if you are going to dig deeper than a foot), this is typically a free and fast service
  • Determine location- spend a day or so with the plant where you think you’d like it (this is especially important if you are planting a tree or something that will get really large), a small forb can be relocated, but you don’t’ want to plant a tree I the wrong spot.  On the other hand, nothing is permanent.
  • Dig a hole that is at least twice as wide as the container the plant is in and deeper than the container height
  • Set plant in hole- check the location of the plant and check hole dimensions.  In the photo below, the hole is not wide enough.
  • Determine final height- This is important, you want the plant to set proud, or higher than the surrounding surface- you want to have a “crowned” effect.   The old adage is “plant it high, it won’t die.  Plant it low, it won’t grow.”  Words to live by. Add loose soil to bring plant up to this height.  
  • The reason for digging the hole deeper than you need to is so you can loosen the soil below the plant and encourage quick root growth and plant establishment.  There are some exceptions to this, though, and some plants that root from the stem (like tomatoes and really water loving plants, I'm sure there are some others, but none really come to mind).
  • Remove the plant and fill the hole with water.  Wait for the water to drain from the hole (as an aside, if you’ve ever wondered if you have well-drained soil or poorly-drained soil, you’ll find out now).
  • Remove the plant from the container (carefully).  If the plant is root bound (hopefully it is- this is a good sign of the plant being ready to plant), break up the roots.  This is important and don’t be gentle or shy.  You want to loosen the roots and break up the tendency to grow in the previous container.  You want the plant to spread its roots and exploit resources.  If the roots stay bound they will quickly deplete the nutrients form the soil.  Also, by breaking the roots, the plants will release a hormone that prompts root growth.  Don’t however, break any taproots, or major roots- you are just trying to break the roots free of the container shape.  The only exception to this is if you are planting fairly mature annuals or if you intend to do a lot of feeding or something.  I don’t know why, but the technique of not breaking the root ball up seems to be all the rage now, but I don’t agree with it, nor do I have any experiences to suggest you should not do it.
  • Depending on how tightly bound the roots are, you may need a soil knife (I am very partial to the A.M. Leonard Soil knife it is one of my favorite tools), or even a pruning saw will work great.
  • OK, now that you have abused the plant (kidding, you did the right thing, really) set it in the hole.  Since this is a native plant, you don’t need any fertilizer, soil amendment, compost or anything!  In fact adding too much compost or nutrients can be deleterious to the plant- it can lead to rapid leaf and stem growth, poor or shallow root development, and a faster life-cycle- that is, they might flower their heads off the first year and die.  In ecology it is like switching from r selected (species whose traits are selected to emphasize high growth rate and short life span) to K selected (slower growth, more investment in offspring, longer lived) traits.  Most of our native plans are water limited and slow growing (long-lived).  They have adaptations to deal with seasonally scarce nutrients and water sources.  Don’t over water or feed our plants.  
  • The only exception to this is if the plant is damaged or severely stressed prior to planting, in that case you may have to add some nutrients to correct a problem, but not to promote excessive growth.
  • Stand back and see if the plant is where you want it, and the best "face" is forward, make any adjustments, and add some more water and let it drain.  This might dislodge soil form the roots, but ultimately it will help remove any air pockets (aka, root killers).  Add soil, and when you get it about half way full, water again and let it drain- this step should get rid of any air spaces.  Finish filling the hole, and crowning the top.  Water again until it is saturated. 
  • Mulch.  Mulch is really important, but don’t add too much around the base- you don’t want to end up planting to plant too low (see above and read adage), or promoting secondary root growth around the base.

  • Step back and admire your work.  Plan on watering every other day or every third day for a month, and then weekly thereafter (depending on weather, precipitation, plant species, etc...) through the first growing season.  As always, water deeply and infrequently to promote deep roots.

8th Street Pocket Park

The 8th Street Pocket Park is a small neighborhood park that uses native plants and landscaping to provide education and outreach to neighbors and students that my wife and I have been working on for the last couple of years. Because of its small size and out of the way location, this little piece of ground was neglected, growing only knapweed (Centaurea stoebe) and dog waste (no Latin binomial necessary). Located between an irrigation ditch and the intersection of 8th and Grant streets, the entire "park" was located in the city's right of way. A few neighbors saw an opportunity to work together and develop a wildflower garden, providing beauty and benefits to the nearby school and surrounding neighborhood.

Our goal was to build and maintain this pocket park as a little piece of wild Montana on the corner of 8th and Grant, by using plants native to the Missoula valley and to provide education & outreach to neighbors and students and a little wildlife habitat in our neighborhood. Our hope was that this park will be enjoyed by passersby, and provide a chance to stop and learn about native plants, and wildlife. To that end we developed and installed interpretive signs (see below), paths to interact and view the landscaping and installed benches to help turn this once weed patch into a destination.

In 2008, we completed the south portion (pictured in this post)of the pocket park (with significant help from a $2,000ish neighborhood grant) and we obtained a grant to complete the park this year by expanding the project by landscaping the east portion of the park. We also hope to continue the strong partnerships and neighborhood cooperation that made the first phase so successful.

The aspect of this project I was most concerned about was that as a public park, I wanted the plants to thrive, for weeding to be minimal, and for it to be a good example of native plant landscaping. My hope was that this would give people ideas for this type of landscaping in their own yards, so as a demonstration garden, this needed to look good. To that end, site preparation was essential, and we spent a lot of time on this.

The first step involved getting rid of noxious weeds through hand-pulling and herbicide treatments. The next step involved using a sod cutter to remove the "grass" (read: dog poop, quack grass, lawn, and dandelions). We installed lawn edging around the perimeter (see photo below), then removed all the sod, waited a few weeks, dug out or pulled everything that germinated, repeated this step again, brought in screened top soil, and compost mix to form hills, planted the area and covered it all with 6" of shredded cedar bark mulch.

From the time it was planted until the end of the growing season, we watered the little park every other day heavily. Since October 2008, we have not irrigated it, and have had only one weeding night. The plants have thrived and I think this has been a great public garden example.

Below part of the park is shown, August 2008, after the area was planted.
Below is a picture of the same area in August 2009, after just one year of growth.

Below is just one of several interpretive signs...Again, the same location one year later.This is one of the only "before" pictures we have. Again, you can never take too many pictures before you begin a project- I never take enough (see my lament here). Below, volunteers are installing lawn edging and laying out the split rail cedar fence, in spring 2008. This picture was taken after we removed noxious weeds, so it actually looks like a lawn here- seeing the area as a lawn, in itself, was a lot of work and represented a lot of progress.This picture is taken roughly the same location in early spring 2009, and if you look closely you can see a black-capped chickadee on the nest box. This spring a pair excavated this box and raised a clutch- success!Below is roughly the same location in August 2009- plants thrived, despite no irrigation in 2009.
Since education and outreach were our primary goals of this project, we installed several interpretive signs in this little park. These signs provide information about the history of the park, the partnerships, as well as natural history of the area and specifically about native plants and wildlife found in the park. Below are examples of two of the six interpretive signs.
Also pictured above is a National Wildlife Federation wildlife habitat sign. This park is certified as Backyard Wildlife Habitat because it incorporates the following elements: food, water, cover, places to raise young, sustainable gardening practices, native plants.

Our neighborhood is deficient in parks and open spaces. Landscaping this site transformed existing public space from an unusable state into an attractive pocket park. While the final product of this effort meets a community need (more park space), the process of creating the native plant landscape also meets community needs.

My wife has been working with the local elementary school through the Flagship Program, an after school program for neighborhood children, and has lead field trips for dozens of children to this little garden. She has gone to classrooms to teach kids about native plants, has had them grow plants that we later transplanted to the park, and has had children help pant and weed this park for the last couple of years .

This project was also shared goal of the Montana Native Plant Society and the University of Montana's natural areas integrated plant management program (my wife's program) to provide education and outreach about native plants and their conservation. Despite the small size of this park, it has addressed multiple community needs, and it is a long way from its former state of knapweed, dog waste, and neglect.

How to remove a lawn

Why remove some lawn? Here are a few thoughts and statistics…
Lawns are now the number one irrigated crop in the U.S., covering over 40 million acres, three times the land area covered by corn and more than wheat. That is a pretty startling fact. We have gone from a nation of growing food crops to ornamental grass. The statistics on water use, maintenance costs and materials, fertilizer, and other resources for lawn care in this country is even more astounding.
For example, in the U.S.:
  • 800 million gallons of gas is burned in lawnmowers every year
  • 67 million pounds of synthetic pesticides are used on lawns
  • 238 gallons of water/ person/ day is used during the growing season
  • Outdoor watering accounts for more than half of municipal water use in most areas

From a wildlife perspective, the lawn is a barren wasteland- a monoculture that supports very little insect and animal life. The only animals and insects that do use the lawn are referred to as pests, and most are invasive, or non-native, and people in the U.S. spend millions annually to control them. Certainly, deer, robins and some other wildlife species will feed in or on a lawn, but the reason is often that there is little else left for them.

Removing all or part of your lawn and converting it anything else is one of the best things you can do for sustainable landscaping, increasing biodiversity, and fostering wildlife in your garden. The smaller your lawn, the less stuff you will need to maintain it- we get by with a small reel mower, that takes up little space, is quiet, does not need fuel, is inexpensive (compared to a gas-powered lawn mower) and is fun to use.

A lawn has its place in a yard- it is useful for a wide variety of activities, but it probably does not need to cover the amount of square footage as it currently does. We have some small lawn patches in our yard (see photo below), and they center on dining and entertaining areas, and though they are remarkably small, they can accommodate a lot of people. Also, the lawn patches are in areas of the yard that receive shade, so even though we do not water them grass grows pretty well. We have removed all the lawn from areas that receive full sun, or were otherwise difficult to grow turf grass. Examine your own yard and think of how little you could live with, and consider lawn as a luxury, indeed it is. a lawn once (and still is) a status symbol,for the aristocrats who could afford to have servants care and maintain it. Turf grass grew easily in the English climate of moderate temperatures and frequent rains. If you live in a climate that can't support a lawn without irrigation, consider the environmental effects of irrigating. Is that the best use for water?
Steps for successfully removing a lawn
Removing a lawn and keeping it away is not that simple, but not that difficult either. It takes care, prep work and patience. It can be done without herbicides or with a very limited amount of herbicides, or with a lot of herbicide if you are so inclined (though I am not). Below are several steps to ensure sucess.
Step one, cut a hole in the lawn (kidding).
Step one- Rent a sod cutter. If you have an area >100 square feet, I strongly recommend a gas powered sod cutter, if the area is smaller, you can get by with a kick style, manual sod cutter. The reason for using a sod cutter rather than a shovel is that a sod cutter removes the sod just below the rooting depth of the grass and removes very little- just a thin veneer of- soil. This saves (literally) tons of soil. Also, by using a sod cutter the sod is reusable (see below). Whereas if you were to just dig up the sod one shovel-full at a time, it is in a less desirable state for reuse. If you are really determined to use a shovel, use a square-bladed shovel and aim to just skim the sod layer off, as opposed to digging straight down.
Mark the area of sod you want to remove. Once it is marked, think about it for a few days, and probably increase the size of the new garden bed. I have never heard anyone say "I wish my garden beds were smaller", or "I sure miss mowing that part of the lawn over there." So remove more lawn than you think you will need, you will be happy you did.

Cut and roll up the lawn, and get it away. This is a very satisfying step- instant gratification.

A couple of notes here- do not try to “solarize”, cover, smother, or spray herbicide to kill the lawn. These methods take too long to be effective (if they are ever is effective at all). It just takes a small bit of grass root left behind for the lawn to come back. I am sure there are some situations where it may work, but I do not recommend it. In our climate, the lawn does not really ever die from covering it, maybe after a few years, but who really wants to spend that long. I suspect even after a few years, once it gets some rain, it will re-grow. Still if you do manage to kill it (either with herbicide or from covering it), then you still have to deal with the sod that is there- it is not like the lawn will just decompose to soil.

Once you have cut and removed the sod the best thing to do is to get rid of the lawn. I have tried composting it, turning it over, etc… It takes a really long time to break down and consumes a lot of space in the process. Even if you keep it in a covered pile, there is always the possibility it will start to re-grow.

People want sod and my advice is to give it to them.

The best thing to do is…put a "free" ad in the newspaper (so 1990’s) or Craigslist (so 2008) or MySpace (so 2009 if you under 30). People love sod, and it will be gone before you know it.

Install lawn edging to keep adjacent lawn from getting into beds (if applicable). Use the largest edging you can find (at least 5-6”).

Spot spray herbicide to any roots or things that the sod cutter missed (or dig them out). For example, sometimes the sod cutter will just knock the top off of a huge dandelion. At this point, it might be best to water the site, wait a week, and see if anything germinates, and then remove it or kill it (dig it up, apply herbicide, use a torch, or something), but often is nice to just proceed to the next step, and a lot more gratifying than having a large patch of dirt to watch for a week, while you are waiting for unwanted plants to show themselves. Add any soil amendments, if necessary – the nice thing about native plants here is you do not need this- though you may want to form hills, or raise the elevation of the newly stripped soil
Then, plant your plants- the fun part. Depending on your garden plan, I recommend adding a layer of some sort of weed mat depending on your garden plan. We like to use newspaper, or cardboard. When you lay down newspaper use several overlapping sheets and wet it with a hose to help conform to the contours of the landscape. The thing with newspaper that I like is that it will be around for a few years while things get established, but eventually it will decompose. Landscape fabric is more or less forever but it could be really useful in an area when you do not want any plants to grow (we have some under our clothesline). Finally, mulch heavily! Don’t skimp on mulch- go for an initial 4-6” application of some sort of mulch. Mulch is a really important step; mulch limits weed growth, retains soil moisture and eventually will break down (this can be good, depending on what your plan is). Some people have concerns about mulch, in particular cedar bark, acidifying he soil. I have not found this to be the case, and maybe that is due to our dry climate, but it does decompose in a few years in our yard. In our front yard prairie, we initially added a lot of mulch (see photo above), but this broke down and now you’d be hard pressed to find any (a good thing, see photo below). Mulch is critical for the first year or so to get plants established (even xeric species), and keep out weeds. Even though we chose native, drought tolerant plants, you have to plan on one season or a year (depending on when you plant stuff) in order to get plants established (that means watering and weeding), beyond that, we have not found a need to water. Mulch really limits the amount of time you will spend weeding.

Although there are many options for mulch, I recommend shredded cedar bark. This is a lumber by-product, and because it is shredded, it stays where you put it. Cedar (western red, in this case) takes longer to decompose than many hardwood mulches. In many cities, you can get free mulch from tree removal services or city arborists that chip and shred trees. In general, this sort of mulch is pretty low quality, filled with a lot of leaves, and small particles. It breaks down quickly (may blow away in a wind storm) and compresses really quickly, but for the right application, it is usually free (a great price) and it is a great use for local materials. We have rented a chipper/ shredder to grind up some shrubs and trees and used that mulch as a base layer, on to which we added shredded, cedar bark mulch. This is a good use for free, low-quality mulch.

Before and after

Our yard and gardens constantly change. That is one of the nice things about gardening and landscaping, plants grow, landscapes change and you can change them.

When we started landscaping our yard, it was mainly a lawn. All the trees, shrubs, flowers, and grasses are ones we planted over the last 9 years.

We started with our front yard- the most public space and have worked or reworked areas as time and out ideas have allowed. Here are a few pictures showing some of the changes. Site preparation is essential, including removing sod, installing edging, something to control weeds (like newspaper or landscape fabric- depending on the site), mulch and careful plant selection. Typically we will water the bed or area we landscape for the first season to allow plants to get established, and beyond that they are on their own. It is critical to water to get the plants established but after the first winter we have found it is really not necessary.
