Ginkgo tree is a unique ancient tree species in China, also known as ginkgo tree, Gongsun tree, duck foot tree, etc., Ginkgo biloba is a deciduous tree of Ginkgo biloba family, its tree appearance is quaint and beautiful, and it is often made into bonsai appreciation. The bonsai trunk is thick, the branches are curved, the roots are exposed, the shape is unique, vigorous and unrestrained, and interesting. It is called one of the unique bonsai trees in China. Let's take a look at how to raise potted ginkgo trees.

Growth habit

Ginkgo biloba is a light-loving tree with deep roots and wide adaptability to climate and soil. It can grow in areas with high temperature and rain, few rainfall and cold winter, but it can grow slowly or poorly. It can grow on acidic soil (pH value 4.5), calcareous soil (pH value 8) and neutral soil, but it is not tolerant to saline-alkali soil and over-wet soil.

Sowing and reproduction

Ginkgo tree sowing and propagation is mainly used for large-area greening seedlings or the production of cluster-type bonsai. After the seeds are harvested in autumn, the outer seed coat is removed and the seeds with pericarp are dried so that they can be sowed in winter or in spring the following year. If sowing in spring, mixed sand stratification must be carried out to accelerate sprouting. When sowing, put the seed germ horizontally in the sowing ditch. After sowing, the soil is 3-4 cm thick and compacted, and the seedlings can grow to 15-25 cm high in the same year.

Pot planting

Ginkgo biloba was propagated by cutting, ramet, grafting and sowing. Because the ginkgo tree is a deep-rooted tree species, it should be planted in a relatively deep flowerpot, generally in the spring and autumn season, and the requirement for the soil is not high, but if the sandy soil rich in humus, loose and fertile, and good drainage performance can be used, that kind of planted ginkgo will grow better.

Display place

Potted ginkgo trees have requirements for placement, although they belong to light-loving trees, they can not be placed in places exposed to sunlight for a long time. They must choose places where there is a lack of sunlight and where they are ventilated and wet. To avoid sun exposure in summer, you can take proper shade. Although ginkgo trees are hardy trees, they should still be buried in pots in winter, which is the safest way to spend the winter.

Rational watering

Ginkgo trees like moist soil, but do not basin the soil and produce stagnant water. And ginkgo trees in winter watering is also fastidious, when the winter temperature is higher, the water evaporates faster, generally choose to water sooner or later. If the temperature is general and the basin soil is wet, there is no need to water.

Timely fertilization

Potted ginkgo trees can apply self-made organic fertilizer in winter and must use organic fertilizer, such as rotten bean cake or barnyard manure. After entering spring and summer, ginkgo trees also enter the growth stage, which is more suitable for watering human feces and urine or animal droppings. This kind of fertilizer can make the leaves grow and keep the green leaves green.

Shaping and pruning

Ginkgo trees should be pruned before sprouting in spring, because of their large leaves, sparse branches should not be dense, small and medium-sized bonsai, leave 3-5 branches. At the same time, the branches are properly banded or trimmed according to the needs of modeling, so as to reveal the trunk with certain twists and turns for people to watch.

Turn the basin at the right time

Generally, potted plants need to be turned over, and potted ginkgo trees are no exception. Potted ginkgo trees are usually turned once every two years and need to be carried out in the Spring Equinox season. When turning the basin, it should be noted that the well-developed roots of ginkgo trees can be properly cut, and then 1/3 of the old soil should be replaced with new soil, and base fertilizer should be put into the bottom of the basin, which is beneficial to the growth of ginkgo biloba.
