How to raise Penglai pine? What are the breeding methods of Penglai pine?

Temperature: The optimum temperature for the growth of Pinus bungeana is between 20-30℃, and it is safe to overwinter when the temperature is above 3℃ in winter.

Lighting: Sufficient lighting should be ensured in winter, and the high temperature in summer should be moved to a well-ventilated semi-shady place for maintenance.

Watering: give enough water during the growing period to avoid water accumulation in the basin. When the temperature drops in autumn, watering should be gradually reduced. Fertilization: Generally, in the growing period, apply fertilizer 1 time a month, and apply more nitrogen and potassium fertilizers. Penglai pine has low requirements on soil, so sandy loam with loose ventilation, good drainage and rich humus should be selected.

Precautions:

Penglai pine needs enough water in the spring and summer growth period, but the basin soil can't accumulate water, otherwise it will rot and lose its leaves. The soil in the basin is too dry, and the leaves turn yellow, which causes the leaves to turn yellow or wither. Fertilize every month 1 time, and apply more nitrogen and potassium fertilizer or high nitrate and potassium fertilizer in 20-80-20 seasons. High temperature, strong light or insufficient light in midsummer can also cause yellowing, withering and defoliation. After autumn, the temperature drops and watering gradually decreases. Change pots in spring after 2-3 years of potted plants.

Cut off dense plants and long branches to facilitate ventilation and light transmission. Cut off dead branches and yellow leaves at any time during the growth period to make the plant shape symmetrical and beautiful. Multi-line ramet propagation can also be sown, but the growth at seedling stage is slow. Water fully during the growth period, and gradually reduce watering when the temperature drops in autumn. In order to make the branches and leaves flourish, nitrogen fertilizer and potassium fertilizer can be applied once every 15 days.
