Generally speaking, this kind of plant likes to have enough fertilizer, so it has higher natural requirements, because its growth and development speed is very fast. Of course, the flowering of plants also needs a large number of nutrients, and the soil selection is good. If the soil itself is not satisfactory, it needs to be remedied with fertilizer.
There are many kinds, such as bone meal, superphosphate, various organic fertilizers (rotten), and so on. But the best use is compound fertilizer, after all, which contains more kinds of nutrients.

In spring, we'd better change the pot for the plants, and use some fertilizer in the soil accordingly. We can add 20 to 20 grams of bone meal, more superphosphate, about 50 to 80 grams.
During the period from May to October, compound fertilizer (containing N, P and K) can be applied every ten days or half a month. This is the most important period, we must pay attention to
I believe that we are familiar with the winter treatment, because plants will be in a dormant state, there is no special requirement for fertilizer, so the whole winter can be directly without application.

When plants are growing and flowering, we must pay attention to the balance of nutrition, not only one kind of nutrition. For example, if only nitrogenous fertilizer is applied, plants may grow in vain.
The use of fertilizer concentration should also be controlled, not too high, plants like a little thinner fertilizer
Another thing to note is that the fertilizer we put on after we change the basin must be buried deeper. Do not touch the root of the plant directly.
