Are raised beds necessary on an allotment?

No. You can grow successfully in ground-level beds. Raised beds are a design choice that may improve access, give clear edges and help drainage on heavy, waterlogged ground, but they also need materials and filling.

Choose for the plot you have

The RHS notes that ground-level beds work with no-dig because roots can reach the soil below. It also identifies raised beds as an advantage where heavy soil drains poorly. Before building, observe where water sits and check whether the tenancy restricts treated timber or permanent edging.

Defined beds can make a plot look orderly and keep feet off growing soil. However, too many narrow paths use cropping space and need maintenance. Decide the bed width by reach from the paths rather than copying a fixed layout.

Price the whole system

Include edging, fixings, paths and enough suitable soil or organic matter in the plan. Do not bury rubbish or unknown material as fill. A simple ground-level bed may let you start growing sooner and add edges later if they prove useful.
