Elderberry for the cultivation of soil requirements is very low, as long as the soil used is not too viscous, and has a certain degree of drainage permeability. However, the size of flowerpots should be well controlled, and try not to choose too large or too small pots. Also put a layer of small tiles in the flowerpot, which can make the basin soil more drained.
Relatively speaking, it likes sunshine. During cultivation, plants should be bathed in sunshine for a long time. If the light is insufficient, its growth will be affected, and it will hinder its normal flowering.
When it grows, it needs to make up water, because it needs a lot of water during its growth, so it needs to water it in time when the soil is slightly dry. In the rainy season, we should pay attention to the drainage work, which can not be ignored, to avoid excessive water accumulation in the flowerpot. If the soil is too wet, it will damage its root system.
When the plant is in the period of vigorous growth, it needs to be properly fertilized. When it does not bloom, it mainly uses nitrogen fertilizer. After flowering, it can use phosphorus and potassium fertilizer. No matter what fertilizer is used, the concentration should not be too high, or it will be easy to burn roots.
The growth ability of this kind of plant is very tenacious, so irregular pruning is mainly to prune the unhealthy branches, such as diseased branches, weak branches and dead branches.
