Can bougainvillea be grafted?

1. Cutting conditions

① Time: The best time for bougainvillea cuttings is from March to June, because the branches in spring grow vigorously and have strong vitality, and the humidity and temperature of the soil are more suitable for the growth and reproduction of the plant.

② Temperature: When the indoor temperature in northern regions is above 20℃ in winter, cuttings can also be carried out, because its suitable growth temperature is 20-25℃. The indoor temperature in the north is dry and warm, and it is also easy for the plants to survive.

2. Steps for cuttings

Choose one-year-old semi-lignified branches, trim them to 10-15cm, insert them into the soil at a depth of about 4-6cm, and make holes in the soil. Then water them thoroughly and move them to a shaded place at 20-25℃ for maintenance. They will take root in 20-25 days and can be potted after 40 days.

After rooting, it should be moved to the sunlight to fully carry out photosynthetic reaction, ensuring sufficient light for at least 8-10 hours a day to make the plant stronger.

3. Notes

After cuttings, foliar fertilizer should be applied with nitrogen, phosphorus and potassium fertilizers. You can spray 1/1000 potassium dihydrogen phosphate aqueous solution and urea once every ten days.
