Understanding Square Foot Gardening

Square-foot gardening is a method that revolutionizes traditional gardening by dividing the growing area into small, square segments, usually one foot on each side.

This method, pioneered by an American construction engineer turned gardener, Mel Bartholomew, is a game-changer for gardeners, especially those with limited space.

Planning Your Broccoli Plantation in Square Foot Gardening

Strategic planning is essential for growing broccoli in a square-foot garden. The key to success lies in practical layout and spacing.

Designing Your Garden Layout

Start by mapping out your square foot garden, considering factors such as sunlight exposure and proximity to water sources. Decide how many square feet you will dedicate to your broccoli plants based on your overall garden size and other crops you plan to grow.

Spacing for Broccoli

In square-foot gardening, broccoli generally requires one square foot per plant. This spacing ensures that each broccoli plant has sufficient room to grow without competing for resources like nutrients and sunlight.

Preparing for Planting Broccoli

The foundation of a successful square-foot garden is healthy soil. 

Soil Preparation

Broccoli thrives in well-draining, nutrient-rich soil with a sandy and clay loam texture. The soil must be slightly acidic, between 6.0 and 7.0 pH values.

Start by loosening the soil and enriching it with compost or organic fertilizer. This step is crucial to provide the necessary nutrients for robust broccoli growth.

Choosing the Right Location

Select a location in your square-foot garden that receives adequate sunlight, as broccoli needs plenty of light to grow. If you use raised beds, ensure you position them in a sunny spot.

Square Foot Gardening Broccoli Seeds

Selecting and planting the right broccoli seeds is also integral to square-foot gardening.

Seed Selection

Choose broccoli seeds suited for square-foot gardening. Consider the variety’s size, growth rate, and suitability for your climate. Dwarf or compact varieties often work best in confined spaces.

  • Imperial: Thrives in warmer climates but slows down when it gets cooler.
  • Green Magic: Adapts well to heat; features a compact size with smooth heads.
  • Calabrese: Traditional Italian heirloom known for its sizable main head and abundant side shoots.
  • Belstar: Resilient in hot conditions, prolific in side shoots, ideal for regions with mild winters.
  • Burgundy: Features a modest-sized primary head and plentiful purple-hued side shoots.
  • Di Ciccio: A well-known Italian variety, it produces numerous side shoots and is excellent for freezing.
  • Marathon: Notably resistant to colder temperatures.

Planting Broccoli Seeds

Sow the seeds at the recommended depth and spacing for your chosen variety. This usually means giving each broccoli plant its square foot of space in a square-foot garden.

Planting and Growing Broccoli in Square Foot Gardening

Planting and nurturing broccoli in a square-foot garden requires attention to detail for the best results.

Planting Technique

Plant your broccoli seeds or transplants in the designated squares. Ensure each plant has enough space and is planted at the correct depth according to your seed packet instructions.

Growing Broccoli

Regularly care for your broccoli plants, including consistent watering and periodic soil fertilization with 5-10-10 types before planting broccoli.

 Monitor their growth and adjust care as needed to ensure healthy development.

Square Foot Gardening Broccoli in Raised Beds

Growing broccoli in raised beds using the square foot method can offer additional benefits.

Advantages of Raised Beds

Raised beds provide better drainage and can help in soil temperature regulation. They also make it easier to control the soil quality and can reduce the strain of bending down to tend to your plants.

Implementing Square Foot Gardening in Raised Beds

When using raised beds, apply the same square-foot gardening principles. Ensure each broccoli plant has its square foot and that the raised bed receives adequate sunlight and water.

Managing Pests and Diseases

Pests and diseases can challenge growing broccoli, but there are effective ways to manage them in a square-foot garden.

Monitoring and Prevention

Regularly inspect your broccoli plants for signs of pests or diseases. Implement preventive measures such as crop rotation and organic pest control solutions when necessary.

  • Row covers: Use lightweight row covers to create a bug-free barrier and prevent pests from attacking the broccoli plants.
  • Companion planting: Plant companion plants like chamomile, dill, and fennel with broccoli to reduce egg-laying and attract beneficial bugs that eat pests.
  • Neem oil: Treat aphids with neem oil, an organic pesticide safe for humans and pets.

Managing Infestations

If pests or diseases do appear, address them promptly with appropriate treatments. Use organic insecticides or natural remedies, depending on the issue.

Harvesting and Storing Broccoli

Harvesting broccoli at the right time is crucial for enjoying its best flavor and nutritional value.

Harvest Timing

Broccoli is typically ready to harvest when the heads are firm and tight. Cut the central head with a sharp knife, and leave the plant to produce additional side shoots for later harvesting.

Storage Tips

You can store fresh broccoli in the refrigerator for a short period. For more extended storage, blanch and freeze the broccoli heads.

  • To deal with cabbage worms, immerse the broccoli head in chilled, salted water for half an hour before consuming.
  • Store unwashed broccoli in the refrigerator for roughly a week; I prefer using these specific storage containers. Ensure that washed broccoli is completely dry before storing it.
  • For longer preservation, blanching and freezing broccoli can keep it fresh for up to one year. Consult this guide for detailed instructions on freezing broccoli.


Square foot gardening presents a practical and efficient way to grow broccoli, even in limited spaces.

Following the guidelines outlined in this guide, you can enjoy a steady supply of fresh, home-grown broccoli. Whether you’re an experienced gardener or just starting, square-foot gardening offers a rewarding way to maximize your gardening space and enjoy the fruits of your labor.
