cultivation techniques
According to the ecological habits of plum blossom, the high dry land with loose soil, good drainage and sunny ventilation is also selected for open planting. After survival, it is generally unnecessary to water when the weather is not dry. Apply fertilizer three times a year and base fertilizer in winter to improve the ability of wintering and cold protection and prepare enough nutrients for growth in the coming year;
Apply quick-acting flower-accelerating fertilizer before flowering, and quick-acting flower bud fertilizer after new branches stop growing to promote flower bud differentiation, and each fertilization should be combined with watering. Appropriate measures should be taken to prevent cold in winter in the north.
When planting on the ground, special attention should be paid to pruning and shaping. Reasonable pruning is beneficial to control plant type, improve the light condition in crown and promote the early flowering of young trees. Pruning is mainly based on thinning, and it is best to make it beautiful and natural. When pruning, it is advisable to cut off the branches a little. Overweight can easily lead to excessive growth, which will affect the next year's flowering.
