How to grow
Cultivation
Grow as a containerised tree under glass in areas liable to frost. The plant may be placed outside in a sheltered, sunny position during the summer and brought under glass once more in the autumn. In containers, use a well drained, peat-free, loam-based potting soil with extra grit. Water freely during the growing season, March to September and keep the compost just moist during the winter. Apply a balanced fertiliser every two weeks during the growing season, but withhold fertiliser during the winter months
Propagation
Propagate by seed sown in seedbed as soon as ripe; take cuttings of vertical shoot tips in midsummer and root in a cold frame; cuttings of horizontal side branches will not form an upright tree
Suggested planting locations and garden types
- Architectural
Pruning
Pruning group 1; little or no pruning is required, as this can permanently spoil the shape of the tree
Pests
Generally pest-free
Diseases
May be susceptible to honey fungus
