Ginkgo bonsai, Ref. 2480

Ginkgo-unique, mysterious deciduous tree with a history dating back to about 200 million years ago, making it the oldest tree on earth. Requires a change of seasons (climatic conditions).

When growing a dwarf tree, changing the direction of growth of the trunk and branches is done very carefully, protecting the bark from damage, which unlike other plants do not overgrow bark.
Of particular interest is the unusual graceful shape of the leaves and their coloring — bright green in summer and yellow in autumn.

Specifics
A unique mysterious deciduous tree with a history dating back to about 200 million years ago, making it the oldest tree on earth. Requires a change of seasons (climatic conditions). When growing a dwarf tree, changing the direction of growth of the trunk and branches is done very carefully, protecting the bark from damage, which unlike other plants do not overgrow.

Placement
Ginkgo prefers sunlight, so place it in a south-facing window or in a location where it will receive light for at least 6 hours a day. Lack of light can stunt growth and impair leaf coloration.

A natural change of seasons is necessary to stimulate the plant's growth and resting cycles.

Temperature regime
Ginkgo is hardy and tolerates low temperatures. From spring to fall the plant is kept at +18…+25 °C, in summer it should be taken out into the fresh air.

With the onset of fall, the temperature is gradually reduced to +15…+16 degrees. The night minimum should not fall below +10 degrees, as lower temperatures will slow growth.

Lighting
Ginkgo needs a lot of bright lighting. Morning or evening sun is best. In summer, it should be protected from midday sun to avoid leaf burn. In the fall and winter, additional lighting with grow lights is required. The duration of the daylight hours should be at least 6–8 hours.

Soil
A well-drained soil is required. Mixtures of Akadama, pumice, lava and organic compost with a pH of 4–8 are most suitable (see here).

Watering
Ginkgo requires regular watering, especially during hot periods, as its roots do not like drying out. It is important not to overwater the soil.  Between waterings, it is desirable to dry out the top layer.

Leaves can lose their decorative look with low humidity, so spraying is also useful in summer.

Fertilizers
During the period of active growth (spring to early autumn), ginkgo is fertilized with low in nitrogen and high in phosphorus and potassium to strengthen the roots and encourage brightly colored leaves. Balanced organic bonsai fertilizers are good (see here).

Repotting
Young plants are transplanted every 1–2 years in the spring, adults every 3–5 years. When repotting, renew the soil, carefully trim the roots and move to a new, slightly larger pot.

Shaping and pruning
Do the main pruning in spring when the plant is actively growing. Remove unwanted branches and prune those that interfere with the basic form. Leaves can be shortened to create a denser crown.

Ginkgo has fragile branches, so handle pruning carefully and avoid wire shaping, which can easily damage branches. Use soft plastic or cloth tape to guide branch growth.
The cut points must be treated with a special paste or grease that creates a protective layer against bacteria.

Winterization
After leaf fall, the tree goes into resting period and practically does not need any care until spring. Keep it in a cool place, protected from strong frosts.

Diseases and pests
Ginkgo has a strong immunity so is resistant to most diseases and pests, but can occasionally be attacked by aphids. Use a soap solution if pests are detected.
