Raised Beds

What is a raised bed?

An area of soil which is higher than the surrounding garden. A raised bed can be edged with timber, or other material, but may just be a mound of soil. The height is not critical and usually varies from 4″-6″ up to a couple of feet. Deeper beds are often used by people with health problems but remember they will need a lot of soil.

Why use them?

  • Better drainage
  • Warmer soil
  • Deeper layer of topsoil
  • A few inches higher is easier on the gardener’s back!

What to make raised beds out of?

  • Wood but not pressure-treated, old scaffold planks are good.
  • Cinder blocks, very cold weather can sometimes break them.
  • Cedar or redwood, natural insect-repellant.

The soil in beds becomes raised by double digging the bed and the application of organic matter. There is no need to add soil unless you want a very deep bed, say more than 300mm (12 inches) deep.

These are some new raised beds edged with scaffold planks which are about 230mm (9 inches) wide.
