One Season of Square Foot Gardening

a square ft garden

Last year I read Mel Bartholomew’s book “Square Foot Gardening – a new way to garden in less space with less work”. And was inspired to give it try. So bright and early this past spring I built 3 raised beds more or less like Mel recommends in his book and got off to an early start with Square Foot Gardening.

For those of you who aren’t familiar with the concept of Square Foot Gardening it boils down to this:

  • Limit the size of your garden to only what you actually can and will take care of.
  • Garden in Raised Beds – like any raised bed system, you never walk on the soil.
  • Divide your beds into sections that are 12 inches by 12 inches instead of in traditional rows.
  • Manage each of those one square foot sections very intensively.
  • Mr. Bartholomew also embraces organic methods – as do I.

It’s a pretty simple concept and other than the 12 inch grid aspect it is pretty similar to some other gardening systems. In the Square foot Gardening Book, Mel gives lots of very useful information on many aspects of gardening including planting and spacing, composting, trellis systems, seed starting, watering, weeds, pests, and tools and techniques for extending the season. It’s an informative book even if you never try the square foot method.

My Experiences With the Square Foot Gardening Method

First I should tell you that I did not strictly adhere to Mel Bartholomew’s methods. Mel states that if you don’t install some kind of permanent 12″ by 12″ grid then it isn’t really a square foot garden – I didn’t. But other than that I pretty much did follow his plan.

What Went Right

I had some of my best ever results early on in this experiment, my early spring salad crops were super productive, and everything that I planted got off to a great start. I was able to plant and perform other garden tasks any time I wanted to without concern over working in a muddy garden after a rain. This is because with the Square Foot Garden system you don’t step on the soil. Staying ahead of weeds in these beds was really easy, for several reasons – 1) the small size is easy to manage. 2) the use of mulches helps to suppress weeds 3) because of the intensive planting there is just less area for weeds to grow, and it takes less mulch to cover it.

What Went Wrong

I discovered that you have to be careful about what plants you put next to each other. For example, the idea of having only one or two square feet of bush beans planted at one time sounded good to me. This may seem like a ridiculously small amount to many people, but not to me. My wife and I don’t want to preserve food at this point in our lives, we just want high quality fresh produce for the table. So 9 bush bean plants in a single square foot sounds like it would produce exactly the number of beans at one time that I want to pick and string. And it did, however those 9 plants actually want to spread out and cover a much larger area, and were vigorous enough to pretty much over power anything in a neighboring square. Lesson learned – be careful what you plant next to aggressive sprawlers like bush beans.

I also came to the conclusion that for larger plants (tomatoes for example) a larger (16 by 16 or 18 by 18) grid system might be better (Mel actually says this in his book). And in my opinion vining plants like cucumbers, and squash would probably be more practical in a less space intensive system.

The only other negative comment that I have to say about the system is that it seemed to me that the Square Foot Garden beds dried out a lot quicker than the more traditionally cultivated parts of my garden did. I used the exact soil mix that Mel recommends in his book for best results – a mixture of compost, vermiculite, peat moss, sand, and organic fertilizer. I don’t know if the rapid drying was because it drained so well, or just because of the raised beds, or the sustained upper 90 degree temperatures that we had here in TN, but it really was hard to stay ahead of the watering in the Square Foot Garden beds.

My Conclusions About the Square Foot Gardening Method

In my humble opinion this system is ideal for a salad garden, and for any crops that don’t get too big, but less than ideal for very large or sprawling plants. However, Mel Bartholomew indicates that this may be the case in his book, but that the careful gardener can adapt the system to work well for the larger plants. I’m sure that he is right, but for me I’m not sure that it isn’t less trouble to just use a different system for some crops. I’m certainly going to continue with the Square Foot Garden system for those crops that I like in it.

One more thing that I would do different… 

My garden has developed a plague of moles.  It took the varmints a while to figure out how to go under the edge of the beds and get up into all that nice loose organic soil, but when they do it makes for one more unhappy gardener.  So I think I’m going to try putting some kind of wire mesh under the bed or maybe trenched in around the perimeter.  In the immortal words of Rosanna Rosannadanna “If it ain’t one thing then it’s another ‘ If deer ain’t eating your strawberry plants down to the nub, then moles are tunneling under your raised beds.” Or something like that.

Now, go plant something!

    So, David, did the 9 bush bean plants produce enough for cooking all summer? I tried pole beans in a 20″ pot, and they did well for about 3 pickings. Then they lost leaves and shut down production. Again, it could have been our intense heat, but I watered religiously and never saw any wilting. I really like to idea of planting just enough for about a pot of beans a week. Maybe we need to experiment and tinker some more.

    No, not at all, but I didn’t expect them too. They were productive for about 2-3 weeks. And actually one square was only enough because our nest is empty and my lovely wife eats like a bird. However our two appetites probably add up two proper portions.

    Anyway, progression planting is part of the plan for square foot gardening if you have any expectation of prolonged harvests. If the weather continues in the current pattern I’m afraid that some kind of irrigation will be required as well in the future.

    I do the square ft but I mulch with hay…I use to do Ruth Stout and I love her system but there is just so much gravel in our soil where we live now, it was just not practical..so I actually put down hay,,,build my boxes over this and mulch my plants with hay, It seems to hold the moisture in a lot longer. I live on the MS Gulf Coast so it gets pretty hot here too. I allow 2 ft square for my Summer plants, like squash, tomatoes and zuch….

    I am going to try raising cantaloupe on a trellis this year..wish me luck..I heard how some one put the melon in panty hose when it is still small and tied it to a trellis…as it got bigger the nylons would stretch….we’ll see..LOL….I”ll try anything that seems easy.

    Great review of the system. Nice post!

  5. David says:

    @Eve – I’ve seen the melons in the pantyhose trick in pictures and it actually looks like it should work. I’ve heard that pumpkins will actually support their selves if trained on a trellis – I don’t know about that though it would need to be quite a trellis.

    @Mer – Thanks – Great food photography on your blog. I’m envious.

    Thanks to both of you for your comments.

    Hi … Can you tell me which food plants might not get eaten by the squirrels if I do one foot gardens on my deck? They even eat the pansies! Thanks … Thea

  7. @Thea – I have no idea what squirrels won’t eat, but I can tell you this – It’s mighty hard to keep them out of something that they decide they want. Sorry I’m not more helpful.

    Just be glad they aren’t raccoons.

  8. RecycleBill says:

    For Thea: I’ve had very good luck repelling squirrels and most other varmits sprinkling black pepper or spraying pepper based liquids on my plants. Hot stuff repells most critters except birds.

    Now if someone could tell me how to repell my chickens from my garden…..

    Hello David,
    I read your review of Sqr. Ft. gardening and I will say it was nicely done. As to your question/concern with the raised beds drying out faster then other cultivated ground. Your native soil “appears” to be conprised of clay, clay/silt, clay/loam something to that effect. Clay and slit have huge amount of surface area which makes them a media for water to adhere to. Since the raised beds dont have much if any native soil they water holding capacity will go down. This maybe over technical but this covers it. http://cursos.puc.cl/unimit_agl_014-1/almacen/1250293854_lgurovic_sec4_pos0.pdf
