The Best Plants for Square Foot Gardening Every Season

Square foot gardening is a game-changer for growing your own food, and the right plants can make all the difference.

For a spring garden, choose plants like radishes, lettuce, and spinach, which can be harvested in as little as 20 days and thrive in cooler temperatures.

Radishes, in particular, love the cooler weather and can be grown in as little as 15 days, making them a great choice for a quick harvest.

In the summer, heat-loving plants like tomatoes, peppers, and eggplants take center stage, requiring at least 6 hours of direct sunlight and well-draining soil to thrive.

Zucchini and yellow squash are also great summer choices, producing a high yield of delicious summer squash in just 35 days.

For fall gardens, cooler-season crops like broccoli, cauliflower, and kale come into their own, tolerating light frosts and continuing to produce well into the cooler months.

In the winter, hardy plants like Brussels sprouts, cabbage, and carrots can be grown, often producing a harvest in as little as 60 days.

The Roma variety is a popular choice for its high yield and hardiness. It's also an excellent variety for sauces due to its low water content. I've had great success with the Roma variety and use it almost exclusively for tomato sauces.

Tiny Tim is another great option for square foot gardens, as it's a small cherry tomato plant that takes up less space. This means you can use fewer squares and still get a great harvest. The Homestead Tomato is also a semi-determinate variety that's well-suited for square foot gardening.

Carrots are a great addition to any garden, and they can be grown in both the spring and late summer for a fall harvest. They prefer loose, fertile soil and are an ideal crop for a raised bed.

To grow carrots, you can sow 2-3 seeds per hole, about 1/2 inch deep, in 16 holes per square. This will give you a good chance of getting some to germinate. Keep the soil moist and you should have carrots to harvest in 12-16 weeks.

Carrots are easy to grow, but they do require some specific conditions. They need to be sown in drills, but for square foot gardening, it's better to make 16 holes that are a half-inch deep. This will give them the best chance of growing straight and not becoming deformed.

Celery (10 inches between plants) is a great addition to any garden. I like to eat fresh celery with french onion dip, and I grow it from seed, transplanting it in late April or early May.

Celery can be slow growing and somewhat hard to start from seed, so I usually start twice as many seeds as I need to account for some seedlings dying every year.

To keep the soil evenly moist and fertile, I mulch heavily around the plants with dry grass clippings. This helps prevent "Black Heart" disease, which can be caused by uneven soil moisture.

Shading the small transplants until they get established is also important for healthy growth.
