Plants grow slowly before June, so watering should be controlled to avoid lowering the ground temperature. Since July, the growth has accelerated, and the soil should be kept moist. Top dressing three times a year, in early June, mid-July and mid-August. Planting in the open field after the final frost, such as building a small plastic arch shed on the melon pond after planting, uncovering it during the day and covering it at night to keep warm and frost-proof, the planting period can be appropriately advanced. If the fertilizer and water conditions are good, about 25 plants should be planted per mu, and1~ 2 plants should be planted in general gardens.

Find suitable branches on the plant, cut them off and coat them with rooting powder. When this is done, the cuttings should be inserted into the already prepared substrate. When preparing the substrate, we should pay attention to having enough fertility. After Grain Rain, its summer shoots began to germinate, so it is easy to compete with the spring fruits for nutrients, which will also affect the growth of the autumn shoots of bergamot. Therefore, except for a few branches that need to be shaped, all the branches that grow in summer can be cut off. When the fruit trees grow densely, it is necessary to do a good job of thinning. Dense branches will consume nutrients and affect the ventilation and light of fruit trees. At the same time, thin and long branches should be cut off to avoid nutrient loss in the soil.

Pruning in autumn is the most important thing, which is directly related to the number of flowers and fruits. Except for pruning some weak branches, diseased branches and dead branches, the rest branches should not be pruned, and the maintenance should be strengthened when pruning in autumn. This is the key principle. When pruning, bergamot should cut off excessively dense cross branches and overlap branches, and cut off diseased branches, weak branches and dead branches. Pruning can best be combined with changing pots.

In order to avoid overgrowth of trunk, promote branching, expand crown and increase fruiting branches, when the plant grows to about 1 m in the second year after planting, the first branch bending is carried out at noon on sunny days. When bending a branch, tie one end of a bamboo stick to the branch, and pull the fingered citron down slowly and forcefully, which requires a lot of water, especially when it is hot in summer, we should pay attention to strengthen the watering of the fingered citron, keep the humidity of the soil, and ensure the watering amount of the fingered citron. Only in this way can the vines grow better and the leaves are green.
