HUSBANDRY


Propagate: With cuttings, or by air layer.


Placement: Place in full sun.
Protect during extreme heat in summer.


Pruning: Until the tree reaches the structure you want, the basic technique for branch creation is to clip and grow. Allow the branches to grow out and extend and then cut back in the dormant season. There should be an even distribution of the branches and buds all over the tree.


Repotting: Roots are very vigorous and should be repotted fairly frequently, larger trees every 2 or 3 years, shohin every 1 or 2 years. Repot in the spring before the buds open and ensure the soil is well draining.
Soil type: Medium rich, but well draining, with 40-50% fine gravel added to the mix.


Watering: Ginkgo is a special tree that is particularly thirsty and hungry and the cause of problems that arise is almost always due to a lack of water. If the leaves are starting to droop water thoroughly.


Wiring: Use aluminium wire. Wire in the dormant period or in summer.

Sowing the seeds

Working from seed or cuttings is a challenge from the outset, but we are going to take that to another level. We look at working with the more unusual species with an illustrated guide to help you navigate from raw material to the finished tree. Here we see how to grow a Ginkgo from seed.
