1、 Temperature

Triangle plum is afraid of freezing. The curing temperature in winter should be above 7 ℃. When the temperature is lower than 10 ℃, the water must be cut off. When the temperature rises above 10 ℃, slide less water along the edge of the basin at noon in good light

2、 Watering

When the curing temperature is lower than 15 ℃ in winter, it is necessary to water less and open the watering interval. When the curing temperature is higher than 15 ℃ in winter, watering can be done as usual. Weigh the weight of the basin soil and feel that it is obviously lighter and watery. If you can't weigh it, watch the plant leaves wilt and watery

3、 Illumination

Triangle plum has a pleasant light, not to mention the warm and soft light in winter, so we must move the potted plants to the place with the best indoor light. More sun exposure is conducive to the accumulation of nutrients, good light and high maintenance temperature, which is conducive to the safe wintering of triangle plum

4、 Fertilization

If the temperature is low in winter, do not apply fertilizer. The plum is dormant. After fertilization, the plant can not absorb it at all, and it is easy to cause fertilizer injury. If the indoor heating temperature exceeds 15 ℃ and the light is sufficient, thin fertilizer can be applied frequently as appropriate

5、 Pruning

When raising trigonometry plum in winter, we should pay special attention not to re cut. After re cutting, the leaves of trigonometry plum become less, which will affect photosynthesis, reduce the organic matter transported downward, and it is easy to freeze seedlings after the root system runs out of grain. If you want to prune, just cut the plants lightly after the flowers fail, which is conducive to the growth and flowering of Prunus deltoides in the coming spring
