How to propagate bougainvillea

1. Cutting propagation

Choose one-year-old semi-lignified branches, trim them to 10-15cm, insert them into the sand bed, plant them at 20-25℃, they will take root in 20-25 days, and then plant them in pots after 40 days. They will bloom in the winter of the second year.

2. High-pressure breeding

Choose lignified branches, ring-bark them about 15 cm away from the top with a width of about 2 cm, wrap them with moist nutrient soil or paper towels, keep them above 20℃, and they will take root in about 20 days.

3. Grafting propagation

Choose a vigorously growing plant as the rootstock, use the short branch cleft grafting method to graft the branches at the cleft, and wrap them up and down in an eight-shaped shape with plastic cloth strips. When you are finished, wipe off any new buds that sprout from the rootstock. When the shoot is 3-5cm long, it means the grafting is successful.

4. Hydroponic propagation

Fill a plastic bottle or a glass bottle with water, cut thick branches from the plant, and soak them in water. As long as small white spots sprout from the roots, it proves that the rooting is successful. It usually takes about 45 days to take root. Remember to change the water every 2 days. After rooting, it can be transplanted into pots.
