Cutting propagation of Spiraea hempleaf

1. Cutting time

1. Spring. It is best to carry out cuttings in spring because the temperature is most suitable and the climatic conditions in all aspects are very suitable for cuttings. This is the peak growth period of Spiraea hemp-leaved, and the survival rate of cuttings will be very high, generally reaching more than 90%!

2. Summer. Cuttings can also be carried out in summer. Although the climatic conditions in summer are slightly worse than those in spring, the climatic conditions are still favorable for Spiraea hemp-leaved. Cuttings at this time can still ensure that Spiraea hemp-leaved has a certain survival rate.

2. Cutting method

1. Soil cultivation. First of all, the choice of branches should be based on the season. Choose hard branches in spring and softer branches in summer. Then use special branch pruning tools to cut the branches. The branches should be cut obliquely, and the length is generally between 10 cm and 15 cm. After the branches are cut obliquely, soak them in BT rooting powder for a day and a night, and then they can be cut. The culture soil for cuttings must be disinfected before use to avoid infection of the cut surface of the Spiraea hemp-leaved plant, which would affect rooting and germination. Be sure to water it after planting it. Water it thoroughly, but do not let water accumulate in the pot to prevent root rot. Also make sure it gets enough sunlight. However, direct sunlight must be avoided, and generally a sunshade net can be used to block the sunlight. At the same time, the temperature should be controlled at 15-24℃. In this way, the Spiraea hemp-leaved will quickly grow roots, and after about twenty days it can be transplanted into a larger flowerpot for cultivation.

2. Grow in water. Another method of cutting is to grow it in water. The selection and cutting of branches are the same as those for soil cultivation. Finally, the cut branches are placed in clean water for cultivation. However, the water must be changed frequently, preferably once a day. Wait until the branches take root and sprout, and then you can transplant them into pots for planting!
