What is the propagation method for bougainvillea cuttings?
Let me tell you about the propagation method for bougainvillea cuttings and describe the steps for reproducing bougainvillea in terms of floral knowledge, as follows:
The main method of propagation for bougainvillea is cuttage, because cuttings grow quickly and have a high survival rate. The cuttings for bougainvillea are not randomly chosen; they need to be selected according to different times. The following is a detailed introduction to the propagation method for bougainvillea:
I. Cutting Time
Bougainvillea can be propagated throughout the year, but the survival rate is higher in spring, summer, and autumn. The survival rate for cuttings in March to April is about 70%, and it can reach over 90% in May to June. Cuttings in winter generally need to be done in a greenhouse.
II. Cutting Preparation
If cuttings are done in March to April, the cuttings are usually selected from one-year-old branches with short and thick internodes. If cuttings are done in May to June, you can choose the current year's semi-woody branches, selecting branches about 8-10 cm long as cuttings. The lower end of the cut is trimmed diagonally to increase the area for water absorption, and 2 to 3 leaves are retained on top.
III. Soil and Cuttage
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 it with plastic film for 7-10 days to kill bacteria. The thickness of the cutting bed matrix is generally 15-20 cm. After the cut end of the cutting has dried, apply rooting powder and insert it into the soil, with a cutting depth of 3-5 cm. After cutting, the temperature should be maintained at 25-28 degrees Celsius, keeping the soil moist, and placing it in a shaded and well-ventilated area to care for and 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. The potting soil can be exposed to sunlight or watered with hot water, etc., to ensure successful propagation of bougainvillea cuttings.
2. Fertilization
After cuttage, it is necessary to minimize 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, keeping the potting soil moist and avoiding overwatering, as it can lead to root rot.
The above is the full content of what the propagation method for bougainvillea cuttings is and describes the steps for reproducing bougainvillea, hoping it will be helpful to green plant enthusiasts!
