What is square foot gardening?

Square foot gardening is a gardening technique that involves growing plants in small, concentrated plots, maximizing the use of limited space. Instead of traditional rows, square foot gardening divides the garden into individual square feet, each serving as a mini-garden for a specific plant or group of plants. This concept was popularized by Mel Bartholomew in the 1980s and has since gained a following among urban gardeners looking to make the most of their small gardening spaces.

The concept of square foot gardening

The concept of square foot gardening revolves around the idea of intensive planting. Rather than spreading plants out across a large area, square foot gardeners cluster plants together in small square foot sections. Each square foot can accommodate one plant or a specific number of plants, depending on their size and spacing requirements. This concentrated approach maximizes the use of space and allows gardeners to tend to their plants more efficiently.

The principles of square foot gardening

Square foot gardening is guided by a set of principles that make it an attractive option for urban gardeners. These principles include:

  1. Spacing: Each type of plant has a recommended spacing for optimal growth. Square foot gardening adheres to these spacing guidelines, ensuring that plants have enough space to grow without encroaching on neighboring plants.

  2. Companion Planting: Square foot gardening utilizes companion planting to maximize garden productivity. By planting compatible plants together, gardeners can encourage beneficial relationships, such as pest control or enhanced nutrient uptake.

  3. Efficiency: With square foot gardening, gardeners focus on growing what they need and can effectively manage. This approach minimizes waste and maximizes productivity, making the most of limited resources.

How square foot gardening differs from traditional gardening

Square foot gardening differs from traditional gardening in several ways. Traditional gardening typically involves planting in rows, with significant spacing between plants.
