So you’ve noticed current events in terms of shortages at the grocery store and the many problems plaguing our centralized food system, from fires to food recalls to massive bird culls. You’ve decided to take matters into your own hands as much as possible, most notably growing at least some of your own food, and now you’re looking at planning your garden.

Good for you! A good food system has many layers, including a full pantry, local sourcing, and growing as much of your own as possible. There are many ways to provide for yourself, from hydroponics to urban foraging to container gardening and renting a plot from your local community gardens. So how do we make a plan to best utilize our resources and grow as much as we can? Read on!

The first thing required for proper garden planning is a food list.

This list should consist of the food you eat that can be grown in your grow zone. If you don’t know your USDA grow zone, plug the term into your favorite search engine along with your zip code. Knowing this is essential, because it tells you how long your growing season is.

Many plants, such as tomatoes, die at the first touch of frost, whereas potatoes and other frost-tolerant plants can take it down to a hard freeze. Once you know your grow zone, make a food list by listing everything on your plate that can be grown in your zone. Be very specific! If you’re eating salad, write down everything it’s made of. Grow what you eat and eat what you grow.

The next step in planning your garden requires a pencil and paper.

I’ve tried the garden planning apps, and honestly, I prefer the old-fashioned way. So let’s say our food list includes these items: tomatoes, peppers, salad greens (buttercrunch, Romaine, red lettuces, and arugula), spinach, radishes, beets, basil, potatoes, garlic, carrots, cucumbers, beans, peas, squash, and two varieties of mushrooms (red cap and almond agaricus.)

Now measure the space you have available. For the sake of this article, I’m going to discuss my own garden. I have one raised bed of 4’x8’, four beds of 4’x4’, and seven containers. I draw them on paper and measure out 1’ squares. Therefore, I have 32 1’ squares in my big 4’x8’ bed, 16 1’ squares in the other beds, three large containers, and four smaller, 20 gal pot-sized.

The next step is to consider companion planting.

After the tomato-kohlrabi pairing that worked out so poorly, my belief in this has increased considerably. Since potatoes get along with onions and spinach, they’ll go into two of the 4×4 beds. The other two beds hold strawberries, which are perennial.

I plant my garlic in those during my fall plantings. So, two beds will hold potato plants, one seed potato per 1’ space planted 6 inches down. Spinach and green onions are planted between the rows of potatoes using a process called intercropping.

The spinach will mature and be harvested in 4-6 weeks before the potato plants are big enough to shade it out totally. Also, spinach does prefer some shade. It’s not a sun lover, as potatoes are. I write all of this on my paper diagram.

The large 4×8 bed has 32 1’ squares. However, tomatoes will take up much more room than that, and spacing the plants out will allow for better airflow. This is a disease deterrent, as wet leaves invite disease-causing organisms. Trust me: I’ll have plenty of tomatoes!

In order to squeeze three plants into an 8’ space, I mark 2-1/2’ for each tomato plant. That’s one entire row in that bed. Keep in mind that your tomatoes will also require some support, so account for this on your diagram. Which plant goes into which row should be planned by the sun, such that the sun hits the lower plantings first. Otherwise, the taller plantings will shade the shorter stuff out.

There are a wide variety of greens and herbs go along with tomatoes

Greens and herbs like basil, lettuce, mint, borage, parsley, lemon balm, celery, and chive, to name a few, go along well will tomatoes. From my food list, I’ll plant 3-4 kinds of salad greens between the larger plants. Like spinach, these will mature quickly and be harvested before the larger plants have grown enough to shade them out. Beets and radishes can be planted between the rows also, as can carrots. I plan exactly which squares these will occupy.

Squashes (2 plants) tend to be huge but squat plants if they’re staked, or they can be trellised along with cucumbers (3 plants.) Since they are so big, I give them more room in those rows (2-1/2’ each), as I do with tomatoes. I stake so the vines will run along the ground, a kind of natural mulch and weed deterrent. Note exactly which rows and how much of each row this will require on your diagram. I account for every inch of space and every crop I plan to grow precisely on my diagram.

How do you use containers when you’re planning your garden?

The 20-pound rounds are great for beans and peas. Since I can’t really grow animals well in the city, beans are a major alternative source of protein, so I grow as much as I can. I mark four plants per pot on my diagram, as well as where on my deck I plan to place those pots. I might even plant some summer savory and rosemary in those pots.

While radishes are good companions to beans, the pots are too small for them to coexist. Peas can be grown in the same way, so I mark this on my diagram. Three pots of beans, and one of sugar snap peas, are to be located in the corners of my deck near the rain gutters. I trellis these by threading some hemp twine over said rain gutter. Weight is a consideration, but when done correctly, I’ve had great results. The one year I neglected to use the twine, I had angular leaf spot, aphids, and no beans. Air circulation is good.

Don’t forget the mushrooms!

This year, I have 2 Earth box containers, 1’x 2’x 9” deep each. I mark the mushrooms (almond agaricus and wine caps) I intend to grow in them on my diagram. I include a notation of the phlox for the agaricus shroom, which will give the shroom some needed shade while attracting pollinators for the other crops. Then, I diagram what I plan to grow in the VegTrug, an elevated bed that’s slightly larger than 3’ square. There’s a nice ‘V’ in the middle for growing root crops, so why not? I can grow more beets OR radishes OR carrots, along with more salad greens and herbs here. By the way, the leaves of both beets and radishes are edible. When one crop is harvested, I can plant another, and I mark this on my diagram as well. (Learn more about cultivating mushrooms here.)

So there you have it!

  • Thanks for this very useful article, Amy! Where do you buy the 20 lb round containers for growing beans & peas? Do they have to be labelled “food safe”?

    • I bought mine either at the local dollar store or hardware store. I don’t precisely remember. You can repurpose 5 gallon buckets but it would be better if they didn’t have anything toxic in them before you. Even heavy plastics can absorb chemical residues, and those residues can leach into your soil. And therefore, your food.

  • Thank you, Amy. Hope that people have a plot, time and patience to follow your advices. Nothing better than to eat your own salad, tomatos and some berries. Some will find out, that it is cheaper to buy, others that it take too long and that growing vegetables is far too much work … but it is worth it

    • Having just had a sandwich with my own hydroponically grown lettuce, I agree: nothing tastes better than food you grow yourself! Help yourself if it’s cheaper to buy and you’re not worried about chemical sprays or bacterial contamination. People afraid of too much work can starve. Those who refuse to help themselves are not my problem.

  • Anything you can grow yourself is a good thing! You may not provide for all your family needs, but it may free enough resources up for you to get other stuff you DO need, and leave a bit left over to barter with.
    Grow stuff in the house too. grow lights, plants here and there, plus it cleans the air in the house. Every little bit helps.

    • Got that right! I can’t provide 100% of what I eat on my tiny urban lot, but I can provide 10-20%. That much I don’t have to buy! At today’s prices that’s a good thing.

  • I love my little 100 square foot garden. I planted tomatoes in late February and have eaten a couple in the last few days.

    I also drew a map of the garden, I penciled in the plants I planned but used ink when they went in the ground. I also wrote the date and variety.

    I am trying to see how many calories I can get from this N.E. Florida suburban garden. I have bell peppers, 6 tomato plants, two squash, many onions, watermelon, and strawberrys, oh and six sweet potatoes. I had lettuce and cabbage but we ate it all! I should replant, lol.

    My season will end mid July, as it gets too hot. I can get a second crop between late August and December.

    • That’s incredible! My season runs from May-October and that’s it. If it’s not in my pantry by then I don’t have it. Good luck with your research! Have you considered higher calorie crops as well, such as more squash, beans, and peas?

      • I grew speckled butter beans last year but I think I put too much nitrogen on them and they had lots of leaves and not so many beans. Now have six English pea plants that produce a nice serving about every other day. Super tasty. My two squash plants are so prolific that I have more fresh squash than I know what to do with it. I also took a regular Irish potato and planted an eye into a moist fiber pot and later transplanted it into the garden. It’s now about a foot tall and thick.

        One real oddity is that last fall season, I had one of those “patio container” tomatoes that was producing all the way to December. We only had one freeze and I covered everything in the garden. The patio tomato survived and is still making delicious tomatoes! A perinnial tomato?

  • Is there a book/website etc that lists all the companion planting for all the plants? Thank you.
