Potted plants can be planted in the open field in areas where the annual average temperature is above 18℃, the extreme lowest temperature is ≥0℃, the active accumulated temperature above 10℃ is ≥ 5,000℃, and the frost period does not exceed 15 days. The rest areas should be cultivated in greenhouses or greenhouses in cold season, depending on the situation.

(2) Selection of varieties and seedlings: potted plants mainly focus on ornamental value, and have low requirements on fruit quality and varieties. Generally, commercially available varieties such as: 50 species, 5,000 species, Century Jujube, Biyun, etc. can be used, as long as the characteristics are selected. Seedlings should be grafted with high quality, and the interface should be low, preferably below 5-10 cm.

When the new shoots grow to about 5 cm, 3-4 new shoots with roughly uniform distribution are kept as the main branches, and all the other branches are erased, or several branches can be left according to the needs of different plastic surgery. When the main branches are about 50 cm long, a pillar is set beside each main branch. Pillars can be made of bamboo branches or wooden sticks, about 50-60 cm long, and the pillars are bound and fixed with fine wire. Tie the main branches to the pillars with ropes according to the needs of plastic surgery, so that the green jujube bonsai can grow into a certain shape. The shape of bonsai can't be the same, but it should be guided by the situation and varied.

In the early stage, dilute water and fertilizer are mainly applied. In the future, the amount of fertilizer can be increased, and about 30 grams of compound fertilizer can be applied to each plant each time. After flowering and fruiting, appropriate phosphorus, potassium fertilizer or micro-fertilizer should be applied to make the green jujube bonsai grow better. Water should be poured frequently, and the basin soil should always be kept wet, and it should not be watered too much at a time, and it should not be too wet; In the dry season, water is sprayed 2-3 times a day.
