How To Make a Square Foot Garden

Square foot gardening is a popular method of gardening which allows closer planting of vegetables, herbs and flowers, producing a bigger crop in a smaller space with less work.

After I left home, I had always wanted to grow my own vegetables, but my first attempts at starting and maintaining a vegetable garden were quite dismal even though I had a friend help me with digging over the garden bed to prepare it.

My first real success came when I started using the square foot gardening method. The vegetables grew better and I was able to stay on top of the weeding.

This page will give you an introduction to square foot gardening.

1) Square Foot Gardening Boxes

With square foot gardening, you need to think squares and not rows. Your square foot garden boxes should be at least 6 inches deep and no wider than 4 feet. If the box is wider than 4 feet, you would probably need to step onto the garden bed when planting, weeding, harvesting etc and this would compact the soil. The square foot gardening boxes can be longer than 4 feet but the longer they are, the further you have to walk around to get from one side of the garden bed to the other. Each box needs to be able to be divided into foot squares, so the width and length need to be in whole feet, not fractions of a foot. (For example 4' x 5' is good, but 4' x 4½' is not.)

You can build your own square foot gardening boxes - I made my first square foot garden beds from old recycled house bricks. Alternatively you could buy a kit.

2) Square Foot Gardening Layout

Where to place your boxes

Square Foot Gardening Layout

If you're going to have more than one square foot garden bed, it is best to lay them out with a path or aisle between the boxes of at least 2 feet, preferably 3 feet. A path of 2 feet is more space-efficient than a path of 3 feet but you may find 3 feet is more practical. A 3 foot wide path will allow easy access to each bed for working and harvesting. There will be more room for a wheelbarrow or gardening cart or just for kneeling down next to you garden.

When you build your garden beds, it would be wise to first remove all the weeds or place down a thick layer of newspapers or flattened cardboard boxes under the square foot gardening boxes to stop any weeds from growing through.

3) Square Foot Garden Soil Mix

Mel has a really simple recipe for his perfect soil:

1 part peat moss
1 part vermiculite (coarse grade)
1 part compost

Unfortunately. Peat moss is a limited resource which could be depleted in the USA in as little as 20 years. Possible substitutes for peat moss include more compost (you could make your own) and coir dust.

Make your own compost. Don't throw your green scraps away but turn them into nutrient-rich compost for your veggies and flowers.

4) Square Foot Gardening Grids

Once you have put your soil mix into the garden boxes, you will need to mark the bed into a square foot grid. In my first square foot gardens, I used string but this disintegrated too quickly. I have also used garden stakes laid in a grid on the soil. But there are other materials you can use, including Mel's recommendation of old venetian blinds.

5) Square Foot Gardening Spacing

Now for the fun part! Plant a different vegetable, herb or flower crop in each square on your grid. You will plant 1, 4, 9, 16 (or sometimes a different number) of each plant (seeds or seedlings) in one square foot depending on its space requirements.

The garden planning software I use clearly shows how many of each veggie or herb to plant per square foot - see the picture on the right - e.g. 1 cabbage, 4 swiss chards, 9 beetroots, 16 carrots. In this garden planning software in SFG mode, when you click on a plant to place it on your plan, the number used in each square foot will appear in the top left corner.

My Suggestion: Take into account the final height of the vegetables. My silverbeet (swiss chard) took off and totally swamped my little lettuces which then had to stretch for the light.

    I have never heard or square foot gardening before i came across this lens but it given me some good ideas of what you can do with even the smallest of garden space. Thanks.

    No, but it's interesting to read about!

    I've always kinda "winged it" when it came to laying out my garden and it sometimes ends up pretty crowded and tangled. I'm devoting a section to square-foot-gardening this year and I'm planting this weekend...so your tips are very timely. Thank you !

    Wow this is a cool idea, especially with limited room gardens, like mine. Will need to show this to my mom.

    Hey. Thanks for this, it really helped. I am looking at the buisness side of a square foot garden. Specifically, I am trying to see how much money I can make in one year by selling the plants I grow at a retail price. One thing that wasn't clear; how exactly would you construct the raised bed? I know you make a box and lay down newspaper (thanks for the tip) but should the wood be treated? I would think not, (chemicals) but how about how thick the wood should be?

    Very neat lens. I am going to give this a try, perhaps I will have more luck using this method.
