An effective way to grow a lot of food in a limited space is a 'square foot' garden. This unique growing method allows you to grow 16 different crops in an area that's just 1.2m x 1.2m.
Apart from saving space, there are other advantages too. Square foot gardens require minimal maintenance – because the crops are growing quite intensively in a small area, there tends to be less weeds, and when weeds do appear they are easy to remove. There is no need for digging, and crops are easy to reach, without walking on the soil, for tending and harvesting. This means the soil never becomes compacted.
To create a square foot garden, you'll need a raised bed that measures 1.2m x 1.2m. If you have good woodworking skills, you can build this yourself from scratch – or you can buy easy-to-assemble kits.
Place the raised bed directly onto grass or weeded soil in an open, sunny spot in the garden, and fill with compost. The recommended mix in traditional square foot gardens is a third standard compost, a third peat and a third vermiculite.
