Square Foot Gardening Rules 

Square foot gardening follows a set of principles aimed at maximizing space, minimizing maintenance, and increasing yields. Here are the basic rules of square foot gardening:

 

Divide the Garden into Square Foot Sections: The garden bed is divided into small square sections, typically 1 foot by 1 foot. Each square represents a distinct planting area.

 

Use Raised Beds

Square foot gardening often employs raised beds to improve soil drainage, warmth, and accessibility. The raised beds are typically 12 to 18 inches tall.

Deep Soil Preparation

Prior to planting, the soil in raised beds is deeply amended with compost and other organic matter to create a nutrient-rich growing environment.

 

Create a Grid

Within each raised bed, a grid is laid out to divide the bed into the individual square foot sections. This grid can be made of wood, string, or other materials and serves as a guide for planting and maintenance.

 

Plant Intensively

Each square foot section is planted with a specific number of plants, depending on their size. Larger plants may occupy a whole square, while smaller plants may be planted in multiples within a square.

 

Companion Planting

Utilize companion planting techniques to maximize space and enhance plant health. Certain plants are grown together to complement each other, deter pests, and improve yields. 

 

Crop Rotation

Rotate crops annually to prevent soil depletion and minimize disease and pest problems. Different types of crops are planted in each square foot section each year to maintain soil fertility and balance. Hortisketch helps you track what you planted where each season to make sure you properly rotate your vegetables.

 

Intensive Plant Spacing

Plants are spaced closely together within each square foot section to maximize the use of space.

 

Vertical Gardening

Incorporate vertical gardening techniques to grow vining plants (beans, cucumbers, peas) and big plants (tomatoes, peppers, zucchini) thereby utilizing vertical space efficiently.

 

Regular Maintenance

Practice regular maintenance, including watering, weeding, and harvesting, to keep the garden productive and healthy. Square foot gardening minimizes the effort required for maintenance due to its small, manageable size.

 

By following these rules, gardeners can achieve high yields in a small space while minimizing the effort and resources needed for maintenance. Square foot gardening is particularly well-suited for beginners, urban gardeners, and those with limited space.
