1. Avoid stagnant water: Pine is a typical drought-resistant and cold-resistant plant, and it can live well even if we don't water it for a long time. But once you water the pine trees too much, you will kill them. Water 1 time every 3-4 days in spring and autumn, once every 1 ~ 2 days in summer, and keep the soil slightly moist in winter, with an average of 1 time per week. No matter what season, don't accumulate water.

2. Adequate lighting: Many people will forget how to maintain the lighting of pine bonsai. In fact, pine trees have different requirements for light all year round. The sunshine in spring, autumn and winter is mild. Keep it in a sunny place for 3 hours every day. You can accept the sunshine in summer, but it must be moderate. You must avoid the scorching sun at noon.

3, a small amount of fertilization: the amount of fertilization for pine bonsai must be small, but at least once a year in the spring growth period, self-made organic fertilizer, bone meal or egg shell powder will do, and light fertilizer will be added from September to 65438+ 10 to ensure the growth of pine trees. Be careful not to fertilize at other times, especially in winter.

4. Pruning: As a bonsai, the most important thing is pruning. After pruning, pine trees can be regarded as bonsai rather than potted plants. Each time period has different pruning requirements. New pine needles need to be cut off, and old branches and buds need to be cut off in July and August. 165438+ 10 September-June, peel off Huang Lao needle with tweezers, and finally trim it in June of April 38+February.

5, change pots: Many people think that pine bonsai does not need to change pots, but in fact, every plant needs to change pots when it is planted artificially, it is only a matter of time. Pine bonsai is changed every 3 ~ 4 years, and the best time is September ~ 65438+ 10. After a long time, the flowerpot can't bear it, and the soil will lose nutrients and hinder the growth of plants.
