After the potted plants are out of the house, apply 3-4 times a month with decomposed cake fertilizer or hoof slice water. Apply phosphorus and potassium fertilizer several times before flowering. Reduce the amount of fertilizer in autumn. When the growth is vigorous in summer, apply fertilizer once a week. Stop fertilizing in winter.

Pruning method: Prune in spring or after flowering every year, and remove dense branches, dry branches, weak branches, cross branches, etc. to promote new branches. After the leaves and flowers fall during the flowering period, they should be cleaned up in time, and the remaining flowers should be removed in time after flowering. During the growth period, the tops should be pinched in time to promote side branches, facilitate the formation of flower buds, and promote luxuriant flowering. Old plants can be pruned shorter.
