Glastonbury thorn
Also known as: Information to be completed
A rounded deciduous tree about 10m tall, with thorny stems and glossy, deeply lobed leaves. This cultivar comes into leaf early in mild winters, and sometimes also produces an early flush of white flowers, which are smaller than those produced in the main flowering period in late spring. These are followed by dark red berries in autumn

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 or grafting in winter
Growing
Grow in any (not waterlogged) soil in full sun or part shade. Useful specimen trees for town, coastal or exposed gardens. Use for wildlife hedging. See hawthorn cultivation for further advice
