Ginkgo biloba, also known as fan tree, is an upright deciduous tree that reaches 25-30 m in height; this plant is native to China and Japan and is the only survivor of a genus that numbered numerous species in past eras, as evidenced by numerous fossil finds. The gorse has an erect stem, and generally the young specimens have a columnar bearing; over the years the hair tends to widen and become very branched. The leaves are fan-shaped, light green in color, sometimes have two lobes, they grow alternately on the old branches and in bunches on the new shoots; in autumn this plant becomes very decorative taking on a golden-yellow color. The male and female flowers bloom on different trees, therefore they need at least one specimen per sex to produce fertile fruits; female plants at least 20 years old produce fruits as big as walnuts in autumn, which grow together; they have a smooth, bronze-colored skin and give off an unpleasant smell. These plants are widely used as street trees, as they tolerate environmental pollution without problems.
Speaking of which is the best exposure for fan tree specimens it is good to say that ginkgo biloba prefer sunny places, but can adapt to multiple conditions, always growing in a lush and balanced way.
They do not fear the cold, although it is good to repair very young specimens, at least for the first two winters after planting.
The exposure can also be in full sun, as long as the chosen area is well ventilated; ginco plants do not like too hot climates and suffer during sultry summer days, while they are very resistant to harsh climates, even with temperatures below zero of many degrees.
Generally this type of plant is satisfied with the rains; in the case of young specimens and long periods of drought in the summer it is good to water the ginco specimens, to allow them to have better growth and prevent them from showing signs of suffering.
It is good to intervene with moderation, avoiding the formation of stagnant water, which would not be healthy for the fan shaft.
Specimens of plants belonging to this variety prefer well-drained and rich soils, but they grow without any problem in any soil and can withstand saltiness and drought.
When planting a specimen of this type, it is advisable to arrange on the ground bottom mature manure or granular fertilizer, which is able to supply the plant with the necessary nourishment.
The multiplication of Ginkgo biloba trees generally occurs by cutting in spring and autumn; by seed in the spring. For the multiplication of this variety we proceed preferably choosing the male specimens, because the female plants have seeds with a pungent smell.
It is advisable not to intervene with pruning work as this plant tends to dry out the branches that have been pruned.
