1. Do you need to keep pinching the heart?It needs to be constantly pinched, usually at the earliest when the cuttings are alive about a month later, when it is 4-6cm tall and has grown 4 or 5 pairs of leaves. If the individual tops are still growing vigorously, it is necessary to do it again. Generally speaking, if you pinch the tops later, the plants will be taller, and if you pinch the tops earlier, the plants will usually grow shorter. This work is very necessary, and doing it regularly can help the plants grow better. 2. Which position should be picked for pinching and topping?Pinching usually requires cutting off the top pair of small buds, and then observing the growth of the plant. The buds are usually toppled when they grow to about 12 cm in height, 5 cm above the flower buds. Also, after the flowers wither, all the flower branches between the two pairs of leaves at the top should be cut off. Generally speaking, we top it when we need to prepare seedlings. Usually, about 5 pairs of leaves are retained on the plant, and the other young shoots can be cut off and re-grafted. |
