1、 How many months

Bauhinia trees are at about 15-20 ℃ and the humidity is maintained at 80-90%. At this time, the activity is the highest. It is best to choose the growth season in early summer. At this time, the temperature is also appropriate, and it will not lead to decay due to long-term muggy. The humidity in the air is also large, which is conducive to its survival. In addition to summer, you can also choose before growing leaves in early spring. At this time, the growth momentum is good, which is also conducive to the recovery of growth in the later stage

2、 Cutting method

1. Branches: cut the branches of one or two years old as cuttings. It's best to be strong. The length does not need to be too long. It can be kept at about 10cm. The lower part should be cut obliquely to increase the absorption area. The leaves close to the lower part should be removed and cannot be left on it to prevent decay

2. Substrate: the substrate should ensure air permeability and drainage. Vermiculite and river sand are the best. Among these two substrates, the rooting is the fastest, the purity of the substrate should be maintained, and the substrate should be disinfected in the sun before use

3. Cutting: put the branches in the sand bed and put them in a semi shady environment. At the beginning, apply enough water to ensure thorough watering, and spray water to moisturize when the humidity is low in the later stage. Keeping the surrounding temperature between 20-25 ℃ can be conducive to rooting
