What fertilizer does Ziwei apply? When to fertilize? How to apply fertilizer (such as spreading fertilizer on the surface and burying fertilizer underground)

It is suggested that the fertilization concentration should be based on the principle of "thin fertilizer and diligent application", and it is best to apply it once every half a month from beginning of spring to beginning of autumn, or once a month after beginning of autumn, and stop applying fertilizer before winter until beginning of winter. The best fertilization method is to bury the fertilizer about 10-20 cm away from the root of Lagerstroemia indica.

Note: if it is potted, try to use organic fertilizer, and don't apply too much fertilizer at one time!
