Bougainvillea grafting technology

1. Rootstock Selection

Bougainvillea generally uses the same species of purple flowers as rootstock. It requires good growth and no diseases or pests. It would be difficult for other flowers to survive as rootstocks, but grafting the same variety is more conducive to its growth.

2. Scion Treatment

Choose healthy and strong branches for scion, use new branches grown in the current year, and avoid old and overgrown branches. Keep leaves and 2-3 buds on the branches. Pruning should be carried out after the rootstock is prepared. The branches should not be left for a long time after being cut. It can be preserved in clean water for a short period of time, but not more than two days.

3. Grafting

Cut the trunk of the rootstock, flatten the wound, and make a longitudinal cut in the middle, leaving a notch about 2-3 cm deep. Remove the leaves at the bottom of the scion and cut the bottom into a wedge shape about 3 cm long. Insert the bottom of the scion into the notch of the rootstock so that the surfaces of the two wounds fit together. The wound of the scion should be partially exposed to facilitate healing.

4. Bandaging for healing

Use tape to secure the two together. Be sure to cover the wound completely to avoid bacterial infection and disease. After wrapping, you can cover it with a plastic bag to effectively keep it moisturized. You can also wrap it in newspaper to avoid direct sunlight. Generally, it will take two weeks to survive. After one month, the tape should be removed and normal maintenance should be carried out.
