Pruning method of Catharanthus roseus

Catharanthus roseus is a herbaceous plant, which is suitable for potting. However, it should be noted that its plants should not grow too high, so as not to affect indoor decoration and viewing. Therefore, after surviving in the pot, it needs to pick the heart several times to promote more branches and flowers of Catharanthus roseus, and the residual flowers need to be cut off after flowering

In addition, it is also necessary to trim insect branches and strengthen fertilizer and water management. When pruning in winter and summer, insect branches and dry branches should be cut again. At the same time, we should also strengthen the management of fertilizer and water, promote the new shoots of Catharanthus roseus, renew the tree crown and restore the tree vigor

The heart picking work of Catharanthus roseus

In addition to the normal management of fertilizer and water, the key point is to pick the heart and prevent stem and leaf rot in rainy season. The purpose of heart picking is to promote the branching of Catharanthus roseus and control the flowering period at the same time. Generally, when there are 4 ~ 6 true leaves, start to pick the heart. When the new shoots grow 4 ~ 6 leaves, carry out the second heart picking. It is best not to pick the heart more than 3 times

The last heart picking directly affects the flowering period. Generally speaking, the last heart picking in autumn needs to be 25 days away from the initial flowering period, and the last heart picking in summer is 3-5 days earlier than that in autumn

Catharanthus roseus can not pick the heart, but in order to obtain a better plant type, it is best to pick the heart once or twice. The first time in 3 ~ 4 pairs of true leaves; The second time, leave 1 ~ 2 pairs of true leaves in the new branches. In the process of cultivation, regulators can usually be used, but Paclobutrazol cannot be applied< span>
