Fertilizing

Balanced shrub or tree feed once each early spring

Pruning

Little pruning is needed. Remove diseased, damaged, crowded or crossing shoots and unwanted growth. Timing depends on the plant: generally late winter or early spring; plants prone to bleeding and deciduous magnolias need different timing, and deciduous azaleas and lilacs are pruned after flowering.

Propagation

Propagate by seed, sowing as soon as ripe, in a coldframe or grafting in mid-atumn or early winter

Growing

Grow in deep, fertile soil in full sun or partial shade; tolerates wet soils. See tree cultivation for further advice
