There are a number of materials to choose from once you’ve decided that raised beds are for you. Wood is readily available and easy to work with but even when treated it rots quickly and is by far the least long lasting option. Sleepers are more durable but heavy and difficult to cut. They may also have been treated with preservatives in the past which will leak into your soil making it toxic. Bricks need a building expert on hand to ensure a safe construction and can also leak toxic lime into your soil. Concrete blocks will leave you needing either machinery or a strong team of helpers to put into place.
Recycled plastic raised beds are a permanent, maintenance-free option that come in an easy-to-construct kit. No heavy lifting, no plant hire and no team of body-builders required
