Watering

Before planting, select the soil with good air permeability and water permeability, which is conducive to watering. When the upper layer of the basin soil has been dried out, it is necessary to immediately pour enough water, and appropriately reduce the watering in spring and summer, so as to inhibit its excessive growth. It doesn't like too wet soil, so pay attention to daily watering. In rainy weather, watering shall be suspended

Fertilization

Many people believe that fertilization should be controlled in order to avoid allowing plants to grow too long. However, when pruning new buds, it is necessary to apply more fertilizer, and for weak plants, it is necessary to apply fertilizer first and prune new buds, so that it will not affect its germination again

Environment

The environment is full of sunshine and good air circulation, which will also reduce the occurrence of diseases and pests. In winter, simple cold prevention work should be carried out. However, if it is placed indoors, it is better to choose a place with lower temperature as far as possible, and it is best to be exposed to sunlight

Pruning

The best choice for pruning is in winter, when it will go into dormancy. The tree shape can be adjusted appropriately to cut off those with weak rise and eroded by diseases and pests. Buds are picked from March to April every year

When water and nutrients are appropriate, it is useless if the environment is wrong, so all aspects should be combined to raise plants
