Potted chrysanthemum if allowed to grow, it will be tall and thin, small flowers messy, such as the mastery of the following “seven hands” you will receive satisfactory results. 1.

Such as leaf color turn yellow, small and thin leaves, can be divided into multiple 0.3% urea sprayed foliar water, until the color turn green. If the leaves are dark green and green or yellowish brown, stalks less strong, yes
