What can be used to graft sweet osmanthus in the north, and when and how to graft it

1. What can be used for grafting?

It can be grafted with Ligustrum lucidum, Ligustrum lucidum, Fringewood and Fraxinus chinensis. The survival rate of these rootstocks is relatively high, especially Ligustrum lucidum. However, grafting with tassel trees will improve their cold resistance and alkali resistance, making them more suitable for planting in northern regions. In addition, it is also very good to use its seedlings for grafting, and has the best affinity.

2. Grafting time

It is recommended to graft it in spring. In northern areas, it should not be done too early. It should be done after the temperature rises and stabilizes. Specifically, it should be between April and May, when the climate and environment are more suitable, management is easier, and the possibility of survival can be increased.

3. Grafting method

1. Processing the scion: Choose strong branches that have already become woody as scion. Leave one or two leaves on them, cut off the rest, and make sure they have one or two new buds. The bottom should be cut at an angle and both sides should be cut into wedges.

2. Grafting rootstock: After selecting the rootstock, make an incision at the top part, the length of which should be similar to the wedge shape of the scion. Then insert the scion, making sure it is aligned with the rootstock. Leave a little bit of the cut surface outside and finally wrap it tightly with plastic wrap.

3. Post-management: After the grafting is completed, cover it with a plastic bag to keep it warm and moist. It is best to make a few holes on it to allow for ventilation. Generally, the plant will survive after a week and the plastic bag can be removed. In the later stage, the side buds growing on the rootstock should be removed in time to avoid competition for nutrients.
