1、 Do you need to pick your heart all the time

It needs to pick the heart all the time. Generally, it can be cut for the first time when it survives for more than one month. When it is 4-6cm high and grows 4 or 5 pairs of leaves. If the respective tops are still growing vigorously, it needs to be done again. Generally speaking, the plants that pick the heart later are relatively high, and the plants that pick the heart earlier usually grow shorter. This work is very necessary, which can help the plants grow better

2、 Which position is the core picking and topping

The position of the top pair of small buds usually needs to be cut off before observing the growth of the plant. The shoot of topping treatment is usually 5 cm above the flower bud when its height grows to about 12 cm

In addition, after the flower withers, all the flower branches between the two pairs of leaves at its upper end should be cut off. Generally speaking, when we need to prepare seedlings, we top them. Usually keep about 5 pairs of leaves of the plant, and all other buds can be cut off and re cutted.
