Periwinkle is an herbaceous plant, suitable for pot planting. However, it should be noted that its plants should not grow too high so as not to affect the interior decoration and ornamental. Therefore, after it has become alive in the pot, it needs to be picked several times to promote its multiple branches and flowers, and the residual flowers need to be cut off after flowering. In addition, it is necessary to prune the insect branches and strengthen the fertilizer management. When pruning in winter and summer, the insect branches and dead branches should be cut again. At the same time, it is also necessary to strengthen the fertilizer management, to promote the periwinkle hair new branches, renew the crown, restore the tree.

Centering of periwinkle

In addition to normal fertilizer and water management, the focus is on centering to prevent stem and leaf rot during the rainy season. The purpose of coring is to promote periwinkle branching and control the flowering period. Generally, when the true leaves are 4~6, and the new branches grow 4~6 leaves, the second picking should be carried out. It is best not to pick more than 3 times. The last picking directly affects the flowering period. Generally speaking, the last coring in fall is 25 days from the first flowering period, and the last coring in summer is 3~5 days earlier than in fall. Periwinkle does not need to be picked, but it is best to pick it once or twice to get a better strain. The first time in 3~4 pairs of true leaves; the second time, new branches grow 1~2 pairs of true leaves. In the process of cultivation, you can usually use regulators, but you can not apply doxorubicin.
