Commonly used rootstocks for grafting osmanthus fragrans include Ligustrum lucidum, Ligustrum lucidum, Forsythia suspensa, Fraxinus microphylla, Fraxinus chinensis and tassels. Although there are many rootstocks to choose from, not all rootstocks have a very good effect on grafting osmanthus. For example, grafting with Ligustrum lucidum leaves is prone to the phenomenon of thick top and thin bottom. The growth rate of water wax grafting is relatively slow.

According to my personal experience, tassel grafting has the best effect. After grafting, the crown of osmanthus fragrans takes shape quickly, with deep roots and lush branches and leaves. If you don't want to behead, you can use the docking method. Grafting of osmanthus trees should be carried out in tassel growing season, but it is not suitable for rainy season and dog days. The common grafting method of osmanthus trees is docking. Even if the old tassel pile is used for grafting, the survival rate is also very high.

Then the question is, how to graft osmanthus fragrans with tassel as rootstock? In fact, it is also very simple. Just do the following.

1, grafting rootstock treatment

In spring, before the tassels germinate, select the seedlings with relatively vigorous growth and cut them from the ground to about 125px. On one side of the rootstock, cut a knife at the position of about 1/3 with a depth of about 2-75px to prepare for grafting osmanthus fragrans.

2, scion treatment

When selecting sweet-scented osmanthus scions, we should choose 1-2-year-old and robust branches, cut them into about 10-300px, cut the top side into 2-75px, and cut the other side into a small slope with a 45-degree angle. After everything is ready, insert the scion into the joint of the rootstock, align it when inserting, and make the joint fit tightly. Then tie it tightly with plastic film, as tightly as possible. And then cured.

3. Grafting time

The grafting time of osmanthus trees should be carried out in the growth period, but it should be avoided in the rainy season and dog days. The reason is that there is too much rain in rainy season, and the rain enters the interface, which is not conducive to wound healing and affects the survival rate of grafting. If the temperature is too high in rainy days, a lot of water in the tree will evaporate, which is not good for grafting survival. Grafting should be carried out in the morning or evening when the humidity is relatively high, which can reduce the evaporation of water in the tree and is beneficial to the survival rate of grafting.

After grafting, if you want to make osmanthus trees flourish, you should make more efforts in daily maintenance, do a good job in fertilizer and water management, do a good job in pruning and shaping, do a good job in pest control, and cultivate osmanthus trees into bonsai with artistic value.
