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 (seedlings will not come true to type) or semi-ripe cuttings
Growing
Citrus cultivation - grow outdoors in full sun in frost-free areas with a well-drained, neutral or acidic soil. Under glass grow in loam-based potting compost in full light at minimum of 3-5°C
