Carry on watering
Continue watering plants, but try to conserve water and reduce waste by making a plan to target those that need it most. For example, pots and baskets will need watering most days, while mature border plants can usually survive with none at all.
Annuals and any newly planted plants must be watered not only to help them establish but also to keep them in flower. A stressed annual will flower then stop producing blooms. Mulching plants with compost after heavy rain will significantly reduce their need for water.
Use a watering can to soak plants at ground level, which is a much more efficient method of watering than wasteful sprinklers.
