Can bean paste residue be directly used as Chinese rose fertilizer?
Of course not. If the bean dregs are directly buried in the flowerpot, it is easy to get insects, and the insects will bite the roots of the flowers. It is also possible to burn the roots of the flowers directly. It is best to tie the bean dregs in a bag to prevent flies from biting them, then leave them for about 5 days, and then fertilize the flowers when they are a little smelly after mourning.
