In general, the soil of Prunus triangularis is composed of garden soil, rotten leaf soil and fine sand, with appropriate amount of bone meal added. Buy back the small pot of triangle plum directly from the flower market, do not need to change the soil in a short time, just use the original soil. For 1-2 years of cultivation, when the basin is changed, a part of the new soil will be replaced. The matching method is as follows (I won't tell the general people):
Garden soil: rotten leaf soil: sand is mixed in the proportion of 5:3:2, or peat soil: rotten leaf soil: Sand: perlite is mixed in the proportion of 5:2:2:1.
The water demand of Prunus deltoides is relatively large, and the watering is slightly different in each season:
In spring, the growth of the plum is gradually accelerated. It needs to be watered every day, and it often sprays water on the leaves and around to increase the air humidity. In spring, if the water is less, the leaves will fall due to the lack of humidity.
In summer, it needs to be watered twice a day, in the morning and after 4 p.m.
In autumn, after the temperature drops, keep the basin soil moist. When the temperature is lower than 10 ℃, reduce watering and keep the basin soil dry. If the temperature is above 15 ℃, water properly.
Reduce watering in winter, and do not dry basin soil.
Triangle plum is fond of fertilizer. After the warm weather in spring, nitrogen fertilizer is applied once every 10-15 days, cake fertilizer and water are applied once a week in the growth period, and phosphorus fertilizer is applied several times in the flowering period. After autumn cool, reduce the amount of fertilizer, stop fertilization in winter. In the peak season of growth and flowering, 1000 times potassium dihydrogen phosphate solution can be sprayed on the leaves for 2-3 times, or general fertilizer can be applied once every 10 days.
Note: triangle plum is very sensitive to urea. If the fertilizer is not applied properly, it may produce the phenomenon of luxuriant branches and leaves with few flowers. Therefore, special care should be taken when applying urea.
The suitable temperature for the growth of Chimonanthus mume is 20 ~ 30 ℃, and leaves will appear when the temperature is lower than 5 ℃ in winter.
Triangle plum likes light, the plant growth is weak when the light is insufficient, which affects flowering. In winter, it is necessary to place the bougainvillea in a bright place, and the daily illumination time should not be less than 8 hours, otherwise large area of leaves will appear.
1. Flowerpot selection. It's better to choose a rectangular or oval purple sand pottery basin for curing the triangle plum. The color should not be too deep, so it's better to set off the color of the triangle plum. The right flowerpot can not only make the bougainvillea grow healthily, but also look more pleasant to the eye.
2. Shaping and trimming. There will be a large number of natural phenomena such as defoliation bar and falling flowers before and after anthesis, which cannot be avoided. However, it is necessary to do a good job in cleaning up the defoliation, cutting off the damaged branches, and treating the new branches, we should often take heart, promote branches, and ensure vigorous flowering.
3. Pest control. The diseases and insect pests of Prunus deltoides are less, which generally appear in winter and spring. When they leave and enter the house, they will be harmed by scale insects and moths. They will be timely removed and sprayed with chemicals during the family maintenance.
