Tips from the Master
The Square Foot Gardening technique, developed by Mel Bartholomew, is enjoying a surge of recognition with the 2nd edition of his book All New Square Foot Gardening. Bartholomew popularized this super-intensive and efficient gardening method in his original book published in 1981, which spawned a PBS television series. Here's how it's all done.
Bartholomew’s square foot gardening method centers around a 4-foot square raised bed, divided into a grid of 16 squares, in which vegetables, herbs and flowers are densely planted. He uses a special mix of soil that is equal parts peat moss, compost and vermiculite.
Different seeds are planted in each square, in varying numbers, depending on the space required for each plant. For instance, a tomato plant (large) would take an entire 1-foot square, whereas you could fit 4 lettuce plants (medium), or 9 bush bean plants (small) in the same 1-foot square space.
Vining plants, like cucumbers and squash, that ordinarily take up a lot of space grow vertically on frames or netting. Plants requiring more depth, like potatoes or carrots, are grown in a section with higher sides so that 12 inches or more of framed soil is available to them. Watering is generally done by hand, which avoids waste.
The smaller 4’x4’ bed size means that a gardener can easily reach plants from all sides, without stepping in and compacting the soil. A plywood bottom can even be attached to the bed, so it can be raised up to table height for gardeners who have physical difficulties working with traditional beds.
Easy To Maintain
Square foot gardening is super efficient, growing 100% of the crop in 20% of the space, making it ideal for those with space limitations. The densely planted crops can create a “living mulch” of sorts, preventing weeds from germinating or getting firmly established.
The Right Mix
The special soil mix (Mel’s mix) is designed to hold moisture, so it also requires less water. With square foot gardening, you create your soil on top of what already exists on the ground, so those with poor soil, or who are concerned about pesticides from prior use of the land, can succeed and feel comfortable.
Expand and Grow
If you try square foot gardening and get comfortable with it, you can expand your beds, or bring the technique into other areas of your landscape. Before you know it, every square foot of your property may be growing something beautiful and delicious.
