Planning Your Square Foot Garden Design

So, you are going to start a garden! What will you plant, and how much? The best rule of thumb is to start small, and then grow a bit more each season. Otherwise, you will get overwhelmed and burned out!

  1. Write down a list of all the foods you wish to grow. Keep in mind–if you don’t buy it fresh at the store, you probably won’t eat it, even if it’s home-grown and free!
  2. Decide how many squares of each plant you will grow. One or two squares of each is probably plenty! Click here for a table that shows how many plants will grow in each square. Some plants require more than one square. Those are listed on the right of the table.
  3. Add up the total number of squares you need for your garden.
  4. Design your garden.

As you choose a design and layout for your garden, there are several things to keep in mind:

  • Sunlight–your plants will need at least 8 hours per day. So don’t put your garden on the shady side of the yard.
  • Size–do you want one large garden bed, or several smaller ones?
  • Location–will your garden be against a wall that reflects heat? Or in a windy spot of the yard? Will it be surrounded by grass, which is cooler, or on a concrete patio, which retains a lot of heat?
  • Shape–The width of the garden is limited to 2 feet from any edge you can walk by. So if you plan to build along a fence, you will need to have a narrow bed, or break the garden up into several beds.
  • Aisles–3 foot aisles are a minimum! This allows a comfortable amount of room to walk and work, even when your plants have grown to full size.

Here are four different ways to configure 32 square feet of garden. Each is set in the corner of a yard with a fence on both sides. The first plan is 4′x4′, and  sets the garden away from one fence, leaving a 3 foot pathway on both sides and between the gardens.

 Sample Layout 4×4

This 16′x2′ plan puts the garden right up against both fences. But since it cannot be accessed from the side, it can only be 2 feet wide. If it was any wider, there would be no way to reach the plants.

Next is an 8′x4′ plan. Notice it is 3 feet from the fence, giving access on 3 sides.

Sample Layout 8×4

Finally, here is a “T’ design. It takes up the most space in the yard, but is also very attractive.

  1. I don’t know if the “square food garden” concept would work in my case, or how I should approach it. First, I am disabled so my moving around is somewhat limited. Second, my garden area consists of 13 half barrels. Can I do anything with that?? If so, how.

  2. On his website, Mel actually shows some options for those who can’t spend a lot of time bent over. Click here for a picture: http://www.squarefootgardening.com/index.php/Patio-Boxes/2-X-3-Cedar-Patio-Box-With-Legs/flypage.tpl.html

    To apply the SFG method to your barrels, you would use Mel’s Mix instead of dirt and follow the suggested plant spacing.

  3. Thank you for putting your website together! It’s really helpful!

    I’m a first time SFGer…

  4. I live in Ft. Lauderdale and have my 4′ 8′ box build and it is sitting on a concrete deck. I was concerned about drainage and was not sure if plywood or rocks would be better. I filled the entire base of the box with decorative marble chips which are essentially rocks in bags from Home Depot.
    I have not yet added the growing medium as I was concerned the rocks might have been a mistake. Are the rocks too much drainage since the mix is so light? Please let me know your thoughts as I am ready to move forward this weekend.

    Thanks.

  5. I would worry that if the boxes are flat on the concrete it would not allow the soil to drain, and it would pool and drown the roots. I’m not sure if the rocks will improve this much. If it’s made of wood, I might try drilling some holes along the bottom of the box (every couple of feet) and covering the holes on the inside with screening. That way excess water has a way out, but the soil stays in. If you’re using vinyl, they probably aren’t flush to the ground so you don’t need to worry–it will drain.

  6. I enjoy your blog

  7. This has all been really helpful! Thanks so much…I may be coming back with questions once I have planned my layout.
