Ginkgo biloba, also known as the fan tree, is an erect tree with deciduous leaves that reaches 25-30 m in height; this plant is native to China and Japan and is the only survivor of a genus that counted numerous species in past eras, as evidenced by numerous fossil finds. The ginco has an erect stem, and generally the young specimens have a columnar bearing; over the years the crown tends to widen and become very branched. The leaves are fan-shaped, light green in color, sometimes they 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 yellow-gold color. Male and female flowers bloom on different trees, so at least one specimen of each sex is needed to produce fertile fruit; female plants of at least 20 years of age produce fruits as large as nuts, which grow in pairs in autumn; they have a smooth, bronze-colored skin and give off an unpleasant odor. These plants are widely used as road 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, even if it is good to shelter the 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 freezing by many degrees.
Generally this type of plant is satisfied with the rains; in the case of young specimens and long periods of drought in summer it is good to water the specimens of ginco, to allow them to have a better growth and avoid that they may show signs of suffering.
It is good to intervene in moderation, avoiding the formation of water stagnations, which would not be healthy for the fan tree.
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 a specimen of this type is planted, it is good to prepare mature manure or granular fertilizer on the bottom of the soil, which is able to provide the plant with the necessary nourishment.
The multiplication of Ginkgo biloba trees generally occurs by cutting in spring and autumn; by seed in spring. For the multiplication of this variety we proceed by preferably choosing the male specimens, because the female plants have seeds with a pungent odor.
It is advisable to avoid pruning as this plant tends to dry out the branches that have been pruned.
