Ash bonsai maintenance one: watering
In spring, summer and autumn, the ash bonsai must be placed in a sunny place (except for intermittent shading in midsummer to avoid direct sunlight), and the indoor bonsai must also be sun-dried at least three days a day. In winter, there must be sufficient diffuse light to maintain normal photosynthesis of plants.

Ash bonsai maintenance three: environmental temperature
Ash bonsai has two peak seasons in spring and autumn every year. Spring is the time when all things recover and ash trees sprout the most new buds. At this time to erase the excess new shoots in time. After a short dormancy in midsummer, ash trees will usher in a second growth peak in mid-late August each year. Although the new buds are not as many as in spring, they must be erased in time.

Ash bonsai maintenance five: basin soil
In the growing season, it is necessary to apply thin fertilizer frequently to the ash bonsai. In order to facilitate the absorption of the tree and avoid the waste of fertilizer, it is appropriate to apply once every 5-7 days. The fertilization time is generally carried out when the basin soil is dry in the afternoon on a fine day, and the leaves are watered after application. After the ash bonsai is formed, it can be basically done without fertilization. However, in order not to make the physical constitution of the tree too weak, you can apply some amino acid water-soluble fertilizer before the ash leaves in late autumn.
