Botanical Name: Ginkgo Biloba
Commonly known for its dietary benefits, the Ginkgo biloba, along with the dawn redwood, is a living fossil specimen native to China. The Gingko offers a light-grey fissured bark and can produce areal roots, helping this tree to extend its longevity. It is a deciduous plant with alternating clusters of fan-shaped leaves that turn a beautiful yellowish colour in autumn before falling.
Another similarity to the dawn redwood for the Ginkgo is the ability to grow quite high, making it suitable for formal or informal upright styles. But it can also be shaped in many other styles, such as slanting, forest, or cascading.
Location and Position
The Ginkgo biloba is to be kept outdoors all year round in a full-sun position. In winter, a little protection by placing it under a bench can be given when the temperature falls below zero to protect the rooting system. Once the tree is relocated in a pot, it will lose a bit of its hardiness against cold temperatures.
This tree requires a moist, well-drained environment. Do not let the Ginkgo become bone-dry or to be soaking wet; otherwise, the rooting system will suffer, and the tree may perish in the worst-case scenario.
From growing season to autumn, I prefer to fertilise the Ginkgo biloba with an organic liquid fertiliser and then apply solid organic pellets once to cope with winter necessities.
Pruning and Pinching
For maintenance, pinch back new growth to two or three nodes once it is fully extended. Structural pruning is best carried in autumn because the foliage will have fallen, and the structure of the tree will be clearer.
Repotting and Soil
The Ginkgo can be repotted every one to two years (especially when it’s still young) or as soon the roots fill the pot in early spring. Use a well-drained bonsai soil mix.
Autumn appears to be the best time to wire the Ginkgo because you can easily go through the tree, which will have no leaves, offering better visibility for branch placement
