Raised garden beds are fairly easy to construct and even easier to maintain. Here is advice on how to build raised garden beds for your backyard.

Benefits of a Raised Garden

  • Ideal for smaller spaces (versus a conventional row garden)
  • Great for rocky, poor, or abused soil
  • Produces a higher yield for the area, thanks to better drainage and deep rooting
  • Allows for a longer growing season, since you can work the soil more quickly in the spring in frost-hardened regions
  • Makes gardening easier; for example, intensive planting creates shade mulch to keep the weeds down

Construction Tips


  • Many people are concerned about the safely of their wood frame. First, rest assured that CCA pressure-treated wood is banned as it was leaching Arsenic.
  • To ensure that the wood lasts, there are several options:
  1. Regular pressure-treated lumber sold today has a mixture of chemicals applied to prevent the moist soil and weather from rotting it. Although pressure-treated wood is certified as safe for organic growing, some people have reservations about using it and there are various eco-friendly alternatives.
  2. More expensive woods such as cedar contain natural oils which prevent rotting and make them much more durable. They are more expensive to buy but they will last many more years.
  3. Choosing thicker boards can make the wood last longer. For example two-inch thick locally-sourced larch should last ten years, even without treatment.
  • You could also use concrete blocks or bricks. Remember that concrete will increase the pH in soil over time.
  • Some people use railroad ties, however, we would advise against this. Though the very old ones may be fine, newer ties use creosote-treated timber which is toxic.

Planning and Design

  • Consider a location that's level and has the right amount of sunlight.
  • In terms of bed size, 4 feet is a common width. Lumber is often cut in 4-feet increments, and you also want to be able to access the garden without stepping into the bed.
  • Length isn't as important. Plots are often 4 feet wide by 8 feet long or 4 feet wide by 12 feet long.
  • The depth of the bed can vary. Six inches is a minimum. Plants need at least a 6- to 12-inch rooting zone, so 12 inches is ideal.
  • Before you establish the bed, break up and loosen the soil with a garden fork so that it's not compacted. Go about 6 to 8 inches deep. For improved rooting, some gardeners like to remove the top layer (about a spade's depth), dig down another layer, and then return the top layer and mix the soil layers together.

Building the Bed

  • To support timber beds, place wooden stakes at ever corner (and every few feet for long beds). Place on the inside of the bed so that the stakes are less visible.
  • Drive the stakes about 60% (2 feet) into the ground and leave the rest of the stakes exposed above ground.
  • Ensure that the stakes are level so that they're in the ground at the same height, or you'll have uneven beds.
  • Set the lowest boards a couple inches below ground level. Check that they are level.
  • Use galvanized nails (or screws) to fix the boards to the stakes.
  • Then add any additional rows of boards, fixing them to the stakes, too.

Soil for Raised Beds

  • Fill the beds with a mix of topsoil, compost, and other organic material, such as manure, to give your plants a nutrient-rich environment.
  • Note that the soil in a raised bed will dry out more quickly. During the spring and fall, this is fine, but during the summer, add straw, mulch, or hay on top of the soil.
  • Frequent watering will be critical with raised beds, especially in the early stages of plant growth. Otherwise, raised beds need little maintenance.

Plants for Raised Beds

Almost any crop can be grown in a raised bed. Vegetables are most common, but fruits and even shrubs and trees can be planted, too. Remember that some plants will hang over the edge, so try to think about where you are planting what.

Here's one of many plot plans to consider, courtesy of the Alabama Cooperative Extension System.

I am placing a raised bed on

Hello. My husband made me 2

By Malissa

Hello. My husband made me 2 raised garden beds next to the house. Last year we tried our first garden. He had treated the inside so it wouldn't rot. He put down rock first, then mulch & then soil. The plants were really dry looking even though I watered. Tomato plant only produced a tiny tomato. Strawberry plant produced 1 or 2 strawberries. Zucchini didn't produce. Oh....& we ended up with these great big mushrooms along the roots & around edges of the bed. Dumping everything in beds & starting over this spring. Could you help me out on what we messed up on please? & should I use plastic being would was treated & stained?

My first concern is, what did

By Almanac Staff

My first concern is, what did your husband treat the inside of the beds with? You need to make sure that it’s an eco-friendly wood treatment since you’re growing food in that soil. If it wasn’t, instead of starting from scratch again, lining the inside of the bed with plastic will help prevent any chemicals leaching into the soil.

Raised beds do tend to dry out quickly so need plenty of irrigation, and if your growing medium is mostly garden soil then this will dry out much faster than if it was mixed with plenty of compost (or you could use bagged potting soil). Soil on its own is also unlikely to be rich enough for good fruit production. I wouldn’t worry too much about the mushrooms though - their presence is often a sign of healthy soil.

Lots of people do put raised

By georgewilson

Lots of people do put raised beds directly onto concrete these days, but I’m not sure it’s the best idea. Here's a solution though: The easiest way to ensure drainage when putting raised beds directly onto concrete is to cut some small holes in the sides of your raised beds at the bottom to allow excess water to escape. You might want to line the beds with landscape fabric before adding your growing medium to stop the soil leaking out along with the water.

I've been planning a raised

By Lempke

I've been planning a raised bed for ages, but it's been repeatedly put on hold because money is an issue right now. However, I've found a warehouse near me that routinely has lengths of untreated pine available for free. Can you tell me:
How long will entirely untreated pine last?
How much will lining the box with plastic prolong the life of the boards?
How long would treated the boards with a food-safe sealer prolong the life of the boards?
I live in a moderately dry climate, if that effects anything. Thanks for your help!

The lifetime of untreated

By Almanac Staff

The lifetime of untreated pine really depends how thick it is. Thicker wood will obviously take longer to rot. I’d expect you to get a minimum of 5 years out of untreated pine (unless extremely thin), and perhaps up to about 10 years if it’s quite thick (e.g. 2” x 6”).

Using a plastic lining will avoid having damp soil against the wood and will extend the life of the boards -- how long for will probably depend on the type of plastic used. On your question about treating the boards: Again, it would depend on the treatment used. The product should state how often your wood will need to be re-treated, which may give some indication of its lifespan.

The area where I'd like to

By Deborah Beussink

The area where I'd like to have a raised garden is full of tree roots and stumps. It was a cedar grove we cleared had cleared for a garden. Do we need to work up the soil or can we put beds over the existing soil and the roots of plants such as tomatoes will be able to grow deep enough? I have been composting with worms, saved boxes and newspapers. Plan to use the cedar logs for the beds. We could have someone come in and pull out the stumps and break up the soil to help with the old roots. Some of the soil looks really good while most is orange sticky clay and very rocky. I don't think we can dig by hand or till with all the roots and stumps.

If the trees are dead, then

By Almanac Staff

If the trees are dead, then they will rot down. It’s possible that they might ‘rob’ nitrogen from your soil as they rot, so you might find your plants need some additional nitrogen fertilizer, but otherwise it should be fine as long as you use a good rich growing medium. If the roots are attached to living trees, then you will probably find that the roots not only suck up nutrients and water intended for your vegetables, they also invade the beds. Raised beds are a great solution where the underlying soil is very difficult to work, and cedar makes great wood for raised beds; it’s very long-lasting. About 12 inches should be deep enough for most vegetables, but for root crops you might want to build a deeper bed.

The most common height for

By Almanac Staff

The most common height for raised beds is probably 12 inches. This allows for sufficient drainage for most crops. It assumes you have 12 inches or so of good soil beneath the beds. You can go higher (up to 24 inches) if you have a bad back but then you may need to build cross-supports because the sides of the bed could bow from the weight.

Is it recommended to install

By C. Mart

Is it recommended to install a drainage system in a concrete block raised bed to prevent the creation of a mud pit?

Raised beds tend to dry out

By Almanac Staff

Raised beds tend to dry out relatively quickly, and are often used to make it possible to grow a garden where soil drainage is poor, so you should not normally experience problems with drainage in a raised bed. Make sure to mix the soil below with the bed with the soil you’re adding to the bed to prevent the water sitting on top of the garden soil, especially if you have very heavy clay soil. If you're worried that the water will pool on top of it you could leave a few small gaps between the blocks, or drill some holes in them, to let the water escape.

We want to put raised beds in

By ShaneS

We want to put raised beds in the backyard and have septic tanks back there somewhere. The grass grows very well over the tanks - would a raised bed be a mistake over the tanks?
Thanks for your advice.

This is a bit of a grey area

By Almanac Staff

This is a bit of a grey area so we'll advise you best we can: There is a risk of contamination from growing near septic tank leach fields as it’s not always easy to know if the system is working perfectly. As long as the system is working perfectly then you should be able to grow a some edible crops above it, however it’s generally thought that raised beds can reduce the evaporation of moisture from the soil, which isn’t good for the system.

Definitely avoid growing root crops and perhaps leafy greens near a septic tank. Fruiting vegetables such as tomatoes whose fruit is held high above the soil surface should be fine. Personally, I’d consider planting shallow-rooted, pollinator-attracting flowers in the septic tank area instead.

If placed directly onto

By Almanac Staff

If placed directly onto grass, it’s possible that grass and weeds will grow up through the bed. A good option is lining the base of the bed with a porous material such as overlapping sheets of cardboard, several layers of newspaper, or landscape fabric to stop unwanted plants growing up into the bed while still allowing water to soak away.

I wouldn’t be too concerned

By Almanac Staff

I wouldn’t be too concerned about the heat as the raised bed will shade the surface beneath, but I would be worried that the solid surface beneath the beds would cause problems with drainage. You would need to either break up or remove the concrete below the bed, or else make gaps in the sides of the bed for water to escape.

I have been preparing a portion of our yard this week to start a raised bed vegetable garden. I am using organic soil and seeds, so the safety of my vegetables is important to me. I have the garden next to the house, but have read that this may be a bad thing to do because of possible contaminants. Our house is lead-free of paint, but are there other contaminants to worry about? I guess I should have our soil tested. If I want the organic soil in the beds to be as pristine as possible, should I place a barrier between the organic soil and our current soil? Landscape fabric? Rocks? I'm not sure. Thanks so much for any advice.

Many people do grow close to their house without problems, and it's not something I would personally worry about too much, but if you're very concerned at all I would recommend having your soil tested and seek expert advice on the findings.

Also, for the love of Pete,

By Jenoside

Also, for the love of Pete, calling the hard rock-like stuff in your driveway cement is the same as calling a cake by the name flour. It's concrete, of which cement is a component.

Hey, really there's no need

By Tyler_K

Hey, really there's no need for unnecessary ruddiness. But, to be that completely technical guy....

Cement was actually patented in the mid 1800's in Europe and anything from there after of similar mixture in the United States become known as concrete.
Essentially the same thing but known as a different name.
Now It is also true that what we call in the US cement doesn't always have to be of the substance in which was patented in Europe. Similar to the all cactus plants are under the classification of succulents but not all succulents are cactus. We have advanced the word into many other meanings. Such as "rubber cement" or "cement adhesive."

Hence to say, it's a common and reasonable mistake to Americans depending on your generation line I would guess. But to say calling cake by the name of flour is super extreme and can only have the intent to be hurtful and obnoxious. It's a common reality even in the days of 1800's we can say, that flour, and cake, are two separate things. And seeing how you have to mix flour to create a cake makes this example just plan nonsense. You don't need cement to create concrete. Cement and concrete are the same ingredients just mixed to different recipes.

Thank you...
Now please don't purposefully make a comment intending to be hurtful again.

By Jenoside

CCA has never been banned, it was a voluntary effort by manufacturers to stop using it in response to public outcry regarding its use in boardwalks and children's play equipment.

An easy way to ensure that your lumber wasn't treated with CCA is that most companies now use copper azole, which turns the lumber green (copper). If your lumber is green, it was not treated with CCA.

There are many eco-paints on the market these days for wood; your local hardware shop may stock them, or look online.

If the composting process is done correctly it will eliminate the risk from any pathogens or other contaminates. If the compost looks and smells good it should be OK to use.

There are many types of potting soils for different uses. One guideline is to look for potting soil that is even in texture. Avoid soils that are heavy and have large clumps of dirt or contain big chunks of wood or bark.

Looking for some assistance

By Daenna

Looking for some assistance in building a raised garden bed directly on cement. I'll be using the landscape blocks that fit into each other with no mortar. My question is.... I thought I could just put the blocks directly on the cement but after purchasing them, I was informed they need to lay on a minimum of 1 inch of gravel/sand mixture. This seems like a nightmare as now won't sand and gravel continuously leak out of the bottom of my garden bed??? Not to mention cosmetically having the block stand on 1 inch of gravel seems would look a little odd? Apparently this is crucial so the blocks have settling space?? Can anyone confirm or deny this for me? Or share your experience with raised beds directly on concrete??? Thanks!

Numerous questions: The

By Ken Werner

Numerous questions:

The backyard is sand and crabgrass, so I'm thinking of using cement bricks and creating 4 raised beds in a small area (25x40ft) to create a Victory Garden:

(1) what is the dye used in cement bricks and is it nontoxic?

(2) would it be safer to use clay bricks?

(3) if cement raises the pH in the soil over time, how do I counteract that?

(4) does mortar affect soil pH and how do I counteract that?

(5) how do I kill crabgrass without using a toxic method like pouring on gasoline and burning the crabgrass, which will contaminate the sand underlayer (will be using mulch and potting soil in the raised beds)

(6) what is the minimum depth for growing potatos, carrots, tomatos, beans, broccoli, lettuce, collard, bell peppers, garlic, leeks, scallions - or is that info available on the website?

I'm not in a rush to hear responses since this won't happen until Spring 2014.

Thank you to everyone for your responses.

Hi, Ken, Here is some advice,

By Almanac Staff

Hi, Ken, Here is some advice, courtesy of our Almanac Garden Planner App experts:
1) + 2) There are lots of conflicting opinions on this, and it will depend on the type of dye used on the cement bricks you buy - I can only advise you to call the manufacturer. If you're concerned you can use clay bricks, or line the inside of the bed, and underside of the bottom row of cement bricks, with plastic to prevent any possible leaching.
3) + 4) Cement and mortar can raised the pH over time (making it more alkaline) but this does take a very long time - I would only be concerned if you're growing acid-loving plants such as blueberries. Normal mulching using leaves, pine needles etc for acid-loving plants should be sufficient, or you could also incorporate sulphur chips into the soil (not for other fruits or veggies though).
5) The best way to suppress the crabgrass within the bed would be to lay a permeable membrane down on the base soil (eg landscape fabric, which can be bought from most gardening stores) and install your beds on top. The permeable membrane will prevent the crabgrass from growing up into your bed, while still allowing free drainage.
6) About 12" depth is sufficient for most veggies (even potatoes, since normally you hill up earth around potatoes rather than planting them particularly deeply), but if the bed is very small it might be better to allow for a bit more, especially if using a permeable membrane at the base. A larger, deeper bed will also retain moisture better and cool down more slowly in the fall than one that is small and shallow.
I hope that helps!

Cedar is a naturally rot-resistant wood. Eastern red cedar (Juniperus virginiana) is the most rot resistant and will last for years even when in contact with soil. However, it is more expensive. Lining the inside of the garden bed with 6-mil black plastic may prolong the life of the lumber.
