1、 Spring maintenance

The application of phosphorus fertilizer alone is not conducive to the growth of pomegranate branches, or the application of potassium fertilizer alone will not lead to the growth of pomegranate branches in half a year. Otherwise, the application of potassium fertilizer alone will not lead to the growth of pomegranate branches, or the application of potassium fertilizer alone will lead to the growth of pomegranate branches in the spring

Watering should be dry and wet, and watering should be thorough. Because the pomegranate bonsai basin soil is deep, it is difficult to pour it thoroughly at one time. If possible, the basin immersion method can be used for watering, and the whole potted plant can be put into the pool to let the water slowly soak the basin soil. But we can't often use the dip basin method. It's good to use it once a month, and water it normally at other times

2、 Summer curing

Pomegranate blooms in May. At this time, the management is very important. Before flowering, we should pay attention to increasing the application of phosphorus and potassium fertilizer, reducing the content of nitrogen fertilizer and promoting the differentiation of flower buds. When flowering, cut off part of the flowers, keep the large flowers, and remove the "triangle" at the connection between the flowers and the flower stalk. This part will not bear fruit, and will automatically fall off and consume nutrients in a certain period of time

Fertilization should be suspended during the flowering and fruiting period. After fruiting, water and fertilizer management should be strengthened to promote the growth of pomegranate fruit

3、 Autumn maintenance

Autumn is the best time to enjoy pomegranates, but pay attention to fertilization after picking pomegranates. You can apply more phosphorus and potassium fertilizer, but less or no nitrogen fertilizer, so as to prevent plants from growing long branches, which is not conducive to fruit in the coming year. After falling leaves, cut off the bare branches, pest branches, overlapping branches and weak branches, and then gradually reduce water and fertilizer as the temperature decreases, so as to make preparations for entering the house for overwintering

4、 Winter curing

Pomegranate flowers hibernate in winter. If hibernation is not sufficient, it will affect pomegranate flowering the next year. Most families will move the pomegranate to a warm place with heating or air conditioning before winter. In fact, this is not conducive to pomegranate hibernation. The best overwintering temperature of potted pomegranate is - 2 to - 5 ℃. If it is lower than - 10 ℃, it will be frostbitten. If the temperature is higher than 5 ℃, it is not conducive to its full dormancy

Attention should also be paid to the time of entering the house in winter. Entering the house too early will also affect the growth. Enter the room when the temperature drops to about - 5 ℃ in winter and put it in a low-temperature environment not higher than 0-2 ℃. Watering can be controlled once a month
