How to propagate Bougainvillea cuttings
You may not know how to propagate Bougainvillea cuttings and the small knowledge of flowering plant cultivation about the timing and methods of Bougainvillea cutting propagation, which will surely help you. Let's learn about it together!
The main propagation method of Bougainvillea is cutting, because cutting seedlings grow fast and have a high survival rate. The cuttings of Bougainvillea are not randomly selected, they need to be chosen according to different times. The following is a detailed introduction of the cutting propagation method of Bougainvillea:
Ⅰ. Cutting Time
Bougainvillea can be propagated all year round, but the survival rate is higher in spring, summer, and autumn. The survival rate of cuttings in March-April is about 70%, and it can reach over 90% in May-June. Cuttings in winter usually need to be done in a greenhouse.
Ⅱ. Cutting Preparation
If propagating in March-April, choose one-year-old branches with short and thick internodes for cuttings. If propagating in May-June, you can choose the current year's semi-lignified branches, selecting branches about 8-10cm long as cuttings. Make an oblique cut at the bottom to increase the area for water absorption and retain 2 to 3 leaves on top.
Ⅲ. Soil and Cutting
The cutting bed matrix is usually a mixture of coarse river sand, mountain soil, honeycomb coal ash, and sandy soil in a 1:1:1:1 ratio. Add 0.1% carbendazim to disinfect the cutting bed matrix, and cover with plastic film for 7-10 days to kill bacteria. The thickness of the cutting bed matrix is generally 15-20cm. After the cut end of the cutting has dried, apply rooting powder, insert it into the soil, and the depth of cutting is generally 3-5cm. After cutting, the temperature should be maintained at 25-28 degrees Celsius, keep the soil moist, and place it in a cool and well-ventilated area to wait for rooting.
Ⅳ. Precautions
1. Disinfection
The potting soil needs to be disinfected to ensure that the cutting matrix is basically free of harmful bacteria. You can sunbathe the potting soil or pour hot water on the soil, etc., to ensure the successful cutting propagation of Bougainvillea.
2. Fertilization
After the cutting is completed, try to reduce the use of uncomposted or high-concentration fertilizers, as this can easily lead to root damage in Bougainvillea, affecting the survival rate.
3. Environment
It needs to be placed in a well-ventilated area, keep the potting soil moist, and avoid overwatering, otherwise, it can lead to rotten roots.
