Ginkgo biloba 'Denise' is a relatively new introduction and is an outstanding ginkgo with exceptionally tight, dense upright growth rather similar to an Italian Cypress tree in stature. This narrow upright growth makes Ginkgo biloba 'Denise' a valuble architectural addition to many gardens where it can be grown in most situations including container cultivation. As with all ginkgos in the autumn the foliage turns a wonderful butter yellow autumn.
All forms of Ginkgo biloba are extremely hardy and tolerant of a wide range of conditions. If planting in the ground we recommend using good planting compost with root grow and keeping the soil moist but not waterlogged for the first 6 months. Thereafter an annual top dressing with a good fertilizer is beneficial but not essential. Pruning is not necessary except when shaping is required and this should take place in the dormant period.
If planting in a container, use ericaceous compost mixed with 10% John Innes no. 3 added and feed through the growing period with a good general fertiliser - we use organic seaweed extract. If possible, try to avoid the pot freezing for prolonged periods in the winter months. Re-pot every 2-3 years into the next sized container.
Ginkgo biloba is the sole survivor of a group of trees which grew on this planet over 200 million years ago and it has changed very little in all that time. It has survived all our planetary climatic changes and even survived the atomic bomb dropped at Hiroshima in the Second World War. This tree was the closest living organism to the epicentre of the bomb and although blown apart above the ground, sent shoots up after the war and now has a shrine dedicated to it at Hiroshima. It is a true survivor being very tough and untouched by any pests or diseases. Every part of the tree is used in Chinese folk medicine and it is gaining popularity in the West. Even without these attributes the Ginkgo makes a remarkable feature in any garden and is renowned for its spectacular yellow autumn colour. Often seen as a large tree in parks and gardens there are many varieties of Ginkgo biloba available. Some of these can easily be grown in a small garden. All are very well suited to container growing.
