Methods and Precautions for Propagating Bougainvillea
Bougainvillea is generally propagated in spring and autumn, with the best time being March to May each year. A stem about 8-10cm long is selected as the cutting seedling, with 2 to 3 leaves left on top. The bed substrate is usually a mixture of coarse river sand, mountain soil, honeycomb coal ash, and sandy soil in a ratio of 1:1:1:1. After the cut end of the selected cutting has dried in the wind, it is coated with rooting powder and inserted into the soil, with a general depth of 3-5cm for propagation.
Bougainvillea flowers come in various colors such as red, yellow, and purple. Under natural conditions, they bloom in winter and spring, with a flowering period of up to 5 months. Bougainvillea cultivated indoors can bloom all year round with proper care. Generally, pruning is required for potted bougainvillea to ensure better growth of the plant. The pruned branches should not be discarded and can be used for propagation.
Bougainvillea Propagation Time
Bougainvillea is generally propagated in spring and autumn, with the best time being March to May each year. At this time, the temperature warms up, the climate is stable, there is ample rainfall, and the humidity in the environment is suitable, making it easier for bougainvillea to root and grow after propagation.
Bougainvillea Cutting Method
1. Cutting Preparation
If propagating in March or April, the cuttings are usually selected from one-year-old branches with short and thick internodes. If propagating in May or June, current year semi-woody branches can be chosen. A stem about 8-10cm long is selected as the cutting seedling, with the lower end cut diagonally to increase the water absorption area, and 2 to 3 leaves left on top.
2. Soil
The bed substrate is usually a mixture of coarse river sand, mountain soil, honeycomb coal ash, and sandy soil in a ratio of 1:1:1:1, with 0.1% carbendazim added for disinfection of the substrate. The mixture is then covered with a film for 7-10 days to kill bacteria. The thickness of the bed substrate is generally 15-20cm.
3. Propagation
The selected cutting is allowed to dry, then coated with rooting powder and inserted into the soil, with a general depth of 3-5cm for propagation. After propagation, the temperature should be maintained at 25-28 degrees Celsius, keeping the soil moist, and placed in a shaded and well-ventilated area for care while waiting for roots to form.
Precautions for Bougainvillea Propagation
1. Disinfection
The potting soil needs to be disinfected to ensure that the propagation substrate is basically free of harmful bacteria. The soil can be exposed to sunlight or treated with hot water, etc., to ensure successful propagation of bougainvillea.
2. Fertilization
After propagation, it is advisable to minimize the use of uncomposted or high-concentration fertilizers, as these can easily cause root damage to bougainvillea, affecting its survival rate.
3. Environment
The plant should be placed in a well-ventilated area, keeping the potting soil moist and avoiding overwatering, which can lead to root rot.
