Changchun flower is a herbaceous plant, suitable for potting, but it should not be allowed to grow too high, so as not to affect the interior decoration and appreciation, so after the survival of the potting, it needs to go through several heartbeats to promote the multiple branches and flowers of Changchun flower, and the residual flowers need to be cut off after the flower
In addition, it is necessary to prune insect branches and strengthen the management of fertilizer and water. When pruning in winter and summer, the insect branch and dry branch 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 crown and restore the tree.
In addition to the normal fertilizer and water management, the key is to remove the heart and control the stem and leaf rot disease in rainy season. The purpose of heart plucking 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, the heart should be removed. When the new shoots grow 4-6 leaves, the heart should be removed for the second time. The best time is not more than 3 times.
The last time to pick the heart directly affects the flowering period. Generally speaking, the last time to pick the heart in autumn needs to be 25 days away from the initial flowering period. The last time to pick the heart in summer is 3-5 days earlier than that in autumn.
Changchun flower can not pick heart, but in order to get a better plant type, it is best to pick heart once or twice. For the first time, 3-4 pairs of true leaves were used; for the second time, 1-2 pairs of true leaves were left in the new branch. In the process of cultivation, we can usually use regulators, but we can't use Paclobutrazol.
