Plum blossoms need to be fertilized with enough base fertilizer when they are planted, and they also need to be fertilized with base fertilizer after the flowers fade.Usually, the fertilizer is decomposed manure, which has a long effective cycle, can continuously provide nutrients, is very helpful for the growth of plants, and is not easy to cause fertilizer damage.Usually, the base fertilizer is applied to the bottom of the pot and covered with soil to let the fertility spread slowly.
1. Spring topdressing: Plum blossoms need proper topdressing in spring. Generally, it is applied when branches and leaves grow, and cake fertilizer is selected as fertilizer.The nitrogen content in cake fertilizer is very high, which is very helpful for the growth of leaves and branches. Generally, it is applied once every half month, and the concentration should be controlled.If too much cake fertilizer is used, it will not only cause fertilizer damage, but also lead to plant overgrowth, affecting its normal development.
2. Summer topdressing: The flower bud differentiation period of plum blossom is in summer, and fertilization is usually carried out in June.At this time, fertilizer to ensure nutrient balance, in addition to cake fertilizer, need to add appropriate amount of bone meal, so as to supplement phosphorus and potassium elements, for flower bud differentiation is helpful.In order to make nutrients better absorbed, it is generally necessary to irrigate a proper amount of water after fertilization.
3. Top dressing in autumn: By October, the growth of the branches and leaves of the plant has basically stopped, and it is meaningless to continue to supplement nitrogen fertilizer. At this time, only bone powder fertilizer can be applied. The increase of phosphorus and potassium elements is also helpful for the plant to survive the winter. Generally, it is applied once every half month.
4, foliar fertilizer: The above three kinds of fertilizer are applied in the soil, in addition, you can also apply a little foliar fertilizer.Foliar fertilizer is generally water-soluble fertilizer, which can be sprayed on the leaves after adding water, usually using phosphorus and potassium fertilizers, but also can supplement other trace elements.
