It is more appropriate to use organic fertilizer as the base fertilizer. This kind of fertilizer has a long-lasting effect and can continuously provide nutrients for the plant.

In addition, potassium fertilizer can be applied during the growth period of the iron tree, which can make the leaves greener, promote the elongation and thickening of the stems, and enhance the vitality of the plant.
