It is best to raise longevity flowers in winter. Every time a flower blooms, it bursts into a pot, which means good. Put a box at home. But many people say that it is difficult to bloom their longevity at one time. At this time, appropriate pruning can be carried out to help them bloom again. 1. Trim. Because longevity flowers bloom twice on new branches, only after pruning will new leaves and flower buds bloom on both sides of the pruning mouth. After the flowering period, it can be cut from the first pair of leaflets under the flower cluster, or it can be trimmed according to the growth of the plant. This plant is tall and thin. To find the big leaf under the flower, cut a centimeter from the upper part of the big leaf. In addition to pruning the residual flowers, it is also necessary to cut off the old leaves and weak branches with too dense edges, leaving only a few strong main branches to promote the rapid growth of new branches. 2. After fertilization and pruning, nitrogen fertilizer or comprehensive compound fertilizer of nitrogen, phosphorus and potassium should be supplemented in time to provide nutrition for new branches and leaves. Pruning and adequate nutrition can make longevity flowers bloom again, with rich buds and full pots of flowers.
