Climate Change & the Environment

Plants 2

Submitted by Sue O from Barnet u3a

Now we are experiencing hotter and drier summers, which garden plants are going to manage best, especially if there is a hose ban? The RHS and well-known gardeners have produced some helpful recommendations.

In general: improve heavy clay soil with compost, and provide a thick layer of mulch to help retain moisture. Water well, both when first planting/sowing and until the plant is established, then you can taper off.

See the list below for a selection of recommended plants that can manage dry conditions a) in sun/partial sun and b) in shade.

SOME PLANTS THAT CAN TOLERATE DRY CONDITIONS

I have tried to choose plants that cope with clay soils and are reasonably hardy.
Plants that are attractive to pollinators are shown in italics.
