Plants for shade
Bulk-up the soil with compost before planting.
Mulch regularly to conserve moisture and build up soil structure.
Apply fertiliser to compensate for the competition from tree roots.
In very dry areas consider installing an irrigation system.
Prune trees to let more light and moisture into the soil below.
Protect young plants and newly emerging spring foliage from slugs and snails.
Plants grow more slowly in the shade. Start with larger plants for quicker results.
