Site & Soil: Grow in fertile, moist, well-drained neutral to acid soil in full sun to partial shade. Avoid south-facing locations.
Hardiness: Hardy in all of UK and northern Europe.
Eventual Height & Spread: 6m x 5m.
Other: Add a top-dressing of a well-balanced fertiliser around the base of a recently planted tree in late spring and keep it well watered. No routine pruning is required, just remove any dead, damaged or crossing branches in late autumn or winter when they are fully dormant.
