What kind of fertilizer should be used for plum blossom fertilization? When and how to fertilize plum blossom

1. Base fertilizer

When planting plum blossoms, sufficient base fertilizer needs to be applied, and base fertilizer should also be applied to the soil after the flowers fade. Usually, the fertilizer used is decomposed manure residue. This kind of fertilizer has a long effective period, can provide nutrients continuously, is very helpful for plant growth, and is not easy to cause fertilizer damage. Usually, base fertilizer is applied to the bottom of the pot and covered with soil so that the fertility can be slowly dissipated.

2. Topdressing

1. Topdressing in spring: Plum blossoms need appropriate topdressing in spring, which is usually applied when the branches and leaves are growing, and cake fertilizer is used. Cake fertilizer contains a lot of nitrogen, which is very helpful for the growth of leaves and branches. It is generally applied once every half a month, and pay attention to controlling the concentration. If too much cake fertilizer is used, in addition to causing fertilizer damage, it will also cause the plant to grow too tall and affect its normal development.

2. Topdressing in summer: The flower bud differentiation period of plum blossoms is in summer, and fertilizer is usually applied in June. The fertilizer at this time must ensure a balanced nutrient content. In addition to cake fertilizer, an appropriate amount of bone meal needs to be added. This can supplement phosphorus and potassium, which will help the differentiation of flower buds. In order to allow better absorption of nutrients, it is generally necessary to water the plants appropriately after fertilizing.

3. Autumn topdressing: By October, the growth of the plant's branches and leaves has basically stopped, and it is meaningless to continue to supplement nitrogen fertilizer. At this time, only bone meal 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 a month.

4. Foliar fertilizer: The above three fertilizers are applied to the soil. In addition, you can also apply some foliar fertilizer. Foliar fertilizer is generally water-soluble fertilizer, which can be sprayed on the leaves after diluting it with water. Phosphorus and potassium fertilizers are usually used, and other trace elements can also be supplemented.
