The cutting method and precautions of bougainvillea The cutting time and method of bougainvillea

Bougainvillea flowers come in a variety of colors, including red, yellow, and purple. Under natural conditions, they bloom in winter and spring, and the flowering period can last up to 5 months. Bougainvillea grown indoors can bloom all year round if properly maintained. Generally, domestic bougainvillea potted plants need to be pruned to allow the plants to grow better. Do not throw away the pruned branches, as they can be propagated by cuttings.

Bougainvillea cutting time

Bougainvillea is usually planted in spring and autumn , and the best time is from March to May each year . At this time, the temperature rises, the climate is stable, the rainfall is sufficient, and the humidity in the environment is suitable, making it easier for Bougainvillea to take root and grow after cutting.

Bougainvillea cutting method

1. Preparation of cuttings

If the cuttings are made in March or April, the cuttings are usually one-year-old branches with short and thick internodes . If the cuttings are made in May or June, semi-lignified branches of the same year can be selected. The branches with a length of about 8-10 cm are selected as cuttings, and the lower end is cut into an oblique cut to increase the area for absorbing water, and 2 to 3 leaves are retained on the top.

2. Soil

The substrate for the plugging bed is generally made of coarse river sand, mountain soil, honeycomb coal ash, sandy soil, etc., mixed in a ratio of 1:1:1:1, and 0.1% carbendazim is added to disinfect the substrate for the plugging bed, and covered with a film for 7-10 days to kill the bacteria. The thickness of the substrate for the plugging bed is generally 15-20cm.

3. Cuttings

After the selected cuttings are dried, apply rooting powder and insert them into the soil . The cutting depth is generally 3-5cm. After cutting, the temperature should be kept at 25-28 degrees Celsius, the soil should be kept moist, and placed in a cool and ventilated place for maintenance, waiting for rooting.

Precautions for cuttings of bougainvillea

1. Disinfection

The potting soil needs to be disinfected to ensure that there are basically no harmful bacteria in the cutting medium. You can expose the potting soil to the sun, or water the soil with hot water first, etc. This will make the bougainvillea cuttings successful.

2. Fertilization

After the cuttings are completed, it is necessary to try to reduce the use of uncomposted or high-concentration fertilizers , as this can easily damage the roots of Bougainvillea and affect the survival rate.

3. Environment

It needs to be placed in a ventilated place , keep the soil in the pot moist, and avoid overwatering, otherwise it will cause root rot.
