Other forms: mulches
Mulch is a layer spread on soil to hold moisture in. Spread the mulch, a bark mulch, mulch the beds.
It does three things at once: keeps water in, keeps weeds down and feeds the soil as it rots. It goes on damp ground, never dry, because it holds in whatever is already there. Bark, compost and even cardboard all work.
