Leaf and Branch Pruning:

The Ginkgo is best styled in its natural Fan or Flame shape. New shoots should be pruned back to 2-3 buds while young. Leaf pruning does not produce appreciable smaller leaves. As the leafs appear in clusters it is best to reduce the cluster to one or two leafs and let the plant show of its individual fan shaped. Top the tree regularly to encourage faning and branch growth.

Re-potting & Growing Medium:

Young specimens require annual repotting, older specimens every 2-3 years. Repot in spring, preferably early spring, in basic soil mix.

Wiring:

Ginkgo is usually shaped by pruning, but may be lightly wired spring-autumn. Great care must be taken to protect the bark as it is delicate and scars will not heal.
