First of all, water

When dry, the surface of the basin soil is permeable. Five-needle pine likes dry soil, and avoids the growth of dry soil in pots. Like leaf water, you can often spray leaf water. Five needles pine likes moist air. When the weather is dry in summer and autumn, it is necessary to sprinkle water on the ground to increase the air humidity in the small environment.

Second, fertilization.

Five-needle pine doesn't like big and thick fertilizer, and it is easy to hurt its roots if it is fertilized too much. Under the condition of lack of fertilizer and water control, it can promote its growth into an old posture. It can be applied once a month in March-May and September-165438+1October, but it is not suitable for fertilization in June-August. Young trees can apply more spring fertilizer to accelerate their growth, and adult trees can apply more autumn fertilizer to protect their types and meet the needs of overwintering.

Third, pruning

Five needles pine pruning is mainly to pick buds, control growth and keep the tree beautiful. Generally, in March-April every year, before the new buds are elongated into needles, some buds can be removed as appropriate. If the terminal buds are too dense, you can pick more, otherwise you should pick less, and pick buds on sunny days, so that the wound can heal easily. In addition, we should also consider moderate pruning according to the needs of tree beauty, and cut off dense branches, weak branches, dead branches and redundant branches. Branches should be pruned after autumn. In order to prevent the wound from shedding fat, it is best to seal it with wax in time.

Fourth, pest control.

Five needles pine is usually damaged by leaf rust, root rot, sooty blotch, scale insects, aphids, red spiders and so on. In winter, it can be controlled by spraying 30 times sulfur mixture or using pesticides. At the same time, attention should be paid to ventilation and light transmission, and the soil in the basin should not be too wet to prevent pests and diseases.
