1、 Apply sufficient base fertilizer

The application of base fertilizer is more important. It can be padded with rotten organic fertilizer, which can be used as base fertilizer, and then padded with a layer of soil with a thickness of about 1-2 cm. After that, the tiger thorn plum can be planted in, which can separate the fertilizer from the root, or avoid burning the root, which is conducive to the slow release of fertilizer efficiency

2、 Growth period

1. Spring: This is the vigorous period of growth. The demand for nutrients should be greater. It can be met by applying thin fertilizer 2-3 times in the whole season. If too much fertilizer is applied, the roots will be burned. We should also pay attention to the selection of fertilizer species. We should not use too much nitrogen fertilizer, otherwise the leaves will grow in vain, but they will not bloom all the time

2. Autumn: fertilizer can be applied normally in the early autumn. When the temperature drops in the late autumn, fertilizer can be reduced

3、 Dormancy period

1. Summer: in order to breed flower buds, more phosphorus and potassium fertilizer can be applied from the beginning of bud pregnancy, which can be satisfied once or twice. When the temperature is above 35 ℃, it will enter a dormant state. At this time, fertilization can be reduced

2. Winter: apply enough base fertilizer before winter to ensure good wintering. It's OK to give fertilizer once in the whole winter. If there are signs of flowering, give more
