What is Square Foot Gardening?

Square Foot Gardening has been around for a long time but it is still new to many gardeners. This guide will teach you the key points of this unique gardening approach.

Square Foot Gardening has been around since 1981. It was created as an approach to grow more vegetables per square foot of ground.
In summary, Square Foot Gardening is the approach of separating vegetable beds into 1-foot square sections. Plants are added to each section rather than sown in rows as they were traditionally grown.


Square Foot Gardening is an intensive growing approach where you can plant 3 -4 times the number of plants you would with the traditional row spacing.

Square Foot Gardening: a brief history.

In 1981 Mel Bartholomew created Square Foot Gardening as a new approach to growing vegetables. He felt that there was a much better way to grow vegetables in smaller spaces and in a way that meant less work for the grower. He, therefore, started experimenting with growing fruit and vegetables in 1-foot square sections, publishing his approach in his book Square Foot Gardening. He advised creating 4x4 1-foot beds as the simplest and easiest way to implement his approach. But you can follow his approach using any multiples of 1-foot squares.

How to set up the Square Foot Beds

Bartholomew recommended growing in raised beds, but that is not a hard restriction, and you can follow square foot gardening in any bed type.
Creating the beds is as simple as measuring out the length and width you need. As long as the full bed reaches a multiple of 1-foot squares, you are right. Good weed-free compost is recommended for filling the bed. This is to minimise the risk of perennial weeds and ultimately reduce the work needed in future. Then lay out your beds into 1-foot squares. Ideally, you would use rigid lengths of wood that don't move. But you can also use taught string. Typically SFG growers use thin wooden laths to separate the 1-foot sections.

Square Foot Layout / Planning Guide

Laying out your plants in your Square Foot Garden bed is simple but there are a few points you need to consider. Many are the same as you would layout your traditional row-based plantings: *Plan to put a good variety of plants across the bed. This helps to minimise the risk of attracting one type of pest to the bed.

Is Square Foot Gardening up to the hype?

Square Foot Gardening is an excellent way to garden, especially in small gardens. It has been around since 1981 and is a tried and tested approach. It makes a gardeners life easier by maximising the capacity of each bed. In turn, weeds are minimised, with crops covering the entire bed. It is certainly worth giving it a try. Maybe give it a go on one bed.
