A raised vegetable bed from timber is quick to build yourself with boards and corner posts. Choose wood that can handle moisture: Douglas (above ground) or pressure-treated timber for longer life in ground contact.
Materials
- Boards 20–30 mm thick, width to taste
- Corner posts or screw connections
- Root membrane / weed barrier optional
- Stainless steel screws from hardware
Tips
Prevent direct contact between wet soil and the inside face with foil or liner (food-safe). For large beds: sturdy corners and cross-bracing if needed.
Frequently asked questions
Is pressure-treated timber safe near vegetables?
Prefer Douglas or hardwood with a liner; with pressure-treated timber always use a barrier foil between wood and soil.
