At our Allotment there is the general attempt by members to place scaffolding boards around the edge of their planting areas and also to lay down plastic sheet covered with wood-chip on the surrounding paths.
This keeps the loose earth contained behind the boards at the edge and the paths free of wet mud.
These scaffolding boards are about £13 each and after a few years partly buried in the ground start to rot away.
Is there a cheaper and more durable alternative to the scaffolding boards, to do this job ?
I have in mind perhaps something like overlapping imitation roof slates?
Grateful for any *inexpensive* alternatives to scaffolding boards. Thanks.
