Fertilization time for calamus

The time for fertilizing calamus should be determined according to its growth time. Normally, it should be fertilized in spring and autumn. Because the plant grows slowly in winter and summer and is in a dormant period, it generally cannot be fertilized.

What fertilizer to use for calamus

Generally speaking, it is more appropriate to apply organic fertilizer and slow-release fertilizer to calamus, because these two fertilizers are long-acting fertilizers, so you will see a significant improvement in the condition of the plant and the leaves will be emerald green only one or two months after application.

In addition, before the calamus blooms, you can add some phosphorus and potassium fertilizers to it. This fertilizer can enhance the plant's immunity and resist viral invasion.

Fertilization method of calamus

If you are using jade fertilizer to calamus, usually one or two grains are enough and you can just soak them in water. If you are using slow-release fertilizers such as Aolv and Xinnuo, about 4-5 grains will be enough. It is better to use less rather than more, and try to keep the fertilizer close to the wall of the pot when using it, and do not let it touch the roots of the plant.

Notes on fertilizing calamus

When fertilizing calamus, you need to understand that it does not mean that you must fertilize the plant. If it grows well, you do not need to fertilize it. If it becomes yellow and grows slowly due to lack of fertilizer, you can consider applying a small amount of fertilizer in these cases.

In addition, after fertilizing the calamus, you should observe it frequently. If you find fertilizer damage or excessive growth of the plant, you should immediately reduce the amount of fertilizer, or flush it with plenty of water to dilute the fertilizer.
