The suitable growth temperature of penglaisong is between 20-30 ℃, and it can survive the winter safely when the temperature is kept above 3 ℃. In winter, Penglai should be well lit. In summer high temperature season, we should move the Penglai pine to the well ventilated half shade for maintenance, avoid scorched leaves and fallen leaves caused by strong direct light, and reduce the ornamental value of the plant.
During the growth of penglaisong, sufficient water should be given to the plant to promote its growth, but attention should be paid to avoid ponding in the basin soil, otherwise it will easily lead to the occurrence of rotten roots. After autumn, the temperature gradually drops, and the growth of the plant begins to weaken. At this time, watering should be gradually reduced.
During the growth period, fertilizer is generally applied once a month, and more N and K fertilizers are applied.
Penglaisong is not strict to the soil, it is suitable to choose the sandy loam with loose aeration, good drainage and rich humus.
In summer, when the temperature is over 35 ℃, Penglai pine will stop growing, and the leaves will turn yellow. At this time, it is necessary to do a good job of shading in time to avoid strong sunlight exposure, and often spray water on the plants to keep the plants green and beautiful.
In order to facilitate the ventilation and light transmission, the potting work of Penglai pine is generally carried out in spring after 2-3 years, and the over dense plants and long branches are cut off at the same time. In the growing period, we should cut off the dead branches and diseased branches at any time, so as to keep the uniform and beautiful plant shape.
Penglaisong less pests, mainly red spider and scale insect harm, pay attention to timely spray control.
