The art of square foot gardening and these practical tips will help you maximise your available space while enjoying a bountiful harvest. Whether you're a seasoned green thumb or completely new to the gardening world, square foot gardening might be the way to go.
What size is a square garden bed?
The basics of square foot gardening involve breaking down your garden bed into squares of 30 x 30cm (or a square foot) and mapping out how many plants or vegetables you can fit into each area. This is usually done in a raised garden bed to maximise the use of the space.
When working with a 30cm x 30cm square and deciding what to plant, you can use the following to fit either:
- 16 (4 x 4) extra small vegetables
- 9 (3 x 3) small vegetables
- 4 (2 x 2) medium vegetables
- 1 large vegetable in your square foot.
Some plants may not fit in the layout as you will also need to consider things like sunlight (larger plants potentially overshadow and steal all the sunlight or water), and of course, some plants will take up more than a square.
Plants with vines like tomatoes, eggplant, melons and pumpkins, for instance, will require 4 squares to themselves, while zucchini will require up to 9.
What are the benefits of a square foot garden?
The main benefit of square foot gardening is making the most of limited space. Square garden beds can come in different sizes depending on how much space you are working with and the size of your yard. It also provides a strict pattern to those who like routine and order.
What are the disadvantages of square box gardens?
While square foot gardening has its merits, there are certain drawbacks. Some individuals may find it restrictive, as it prescribes a structured layout, which may not suit those who prefer a more fluid gardening approach. Additionally, nature doesn't always conform to the neat square boundaries, which can pose challenges when plant roots and growth exceed their designated squares.
Another notable limitation is that if you later wish to cultivate larger plants or crops, you will need to pull up the entire grid and start again.
