What fertilizer is good for camellia?

Camellia is fertilized in spring, mainly nitrogen fertilizer. Specific types include human or animal manure, or other compound fertilizers. This can promote plants to sprout new branches and buds. As for the frequency, just control it once every four to six days.

First, the main points of camellia fertilization:

1, germination accelerating fertilizer

Fertilization should be as reasonable as possible, organic liquid fertilizer should be used as much as possible, the fertilizer concentration should not be too high, and fertilization should not be too frequent. Apply germination accelerating fertilizer to camellia. Camellia will sprout new buds at 18℃. In order to better assist camellia to do this work, we need to apply germination accelerating fertilizer, which is mainly nitrogen fertilizer. In this way, branches can accumulate more nutrients and create good conditions for flower bud differentiation.

2. Phosphorus and potassium fertilizer promoted bud formation.

What fertilizer should camellia use? If you want camellia to bear more buds, you should apply more phosphorus and potassium fertilizer to camellia after germination, and at this time you need to reduce the amount of nitrogen fertilizer. During use, you should spray the leaves with the mixed diluent of potassium dihydrogen phosphate, a small amount of borax and rice vinegar every 1000 times, which can not only control the overgrowth of camellia oleifera branches, but also control the overgrowth of camellia oleifera branches.

This phosphorus and potassium fertilizer is also used in winter. Although camellia will go into dormancy in winter, there will still be a certain demand for fertilizer to maintain its own growth, so everyone can apply a small amount of liquid phosphorus and potassium fertilizer to camellia. The concentration of fertilizer should not be too strong, and it can be diluted with water before use.

Second, matters needing attention in fertilization

The use of camellia oleifera chemical fertilizer, whether it is granular compound fertilizer or other chemical fertilizers on the market, should pay attention to two points:

The first is that the lighter is better than the stronger. It is best to use it in turn with fat water.

Second, it is better to be less than much. Sprinkle a few camellia flowers around the surface of the pot soil and water them at the same time to make them slowly dissolve in the pot soil. Chemical fertilizer is soluble in water and can be directly absorbed by the roots, branches and leaves of plants, with fast fertilizer efficiency. However, excessive application or short interval will often cause fertilizer damage, so don't overdo it when using it.

Third, the critical period of camellia fertilization.

(1) Apply germination fertilizer in February and March. That is, from flowering to germination, nitrogen fertilizer is mainly used.

(2) Apply pregnant bud fertilizer from May to June, mainly phosphate fertilizer.

(3) Apply flower bud fertilizer and NPK compound fertilizer in June10-June 165438+ 10. You can't apply it after exposure (that is, you can't apply it in winter after 65438+February).

4. What if there is too much fertilization on camellia?

In the case of over fertilization, we can only try our best to save it. First of all, the soil of potted plants should be changed frequently, because a large amount of fertilizer will accumulate in the soil after one or two years of use, which is not good for the growth of camellia. If the phenomenon of fertilizer damage has appeared, it is best to change pots immediately, or trim plants and carry out cutting or grafting propagation again to make camellia grow again.
