How to Graft Diospyros cathayensis? Detailed Explanation of Grafting Methods and Technical Key Points

Diospyros cathayensis is a shrub-type plant, also known as "pinglan." It is a plant used for making bonsai. Because its fruit looks very much like a bullet, people call it "jindanzi" (golden bullet). One thing that sets Diospyros cathayensis apart from other bonsai plants is that it has separate female and male plants. These two types differ in flowering and fruiting. Moreover, most Diospyros cathayensis plants can only flower and fruit reliably after grafting. So how do you graft Diospyros cathayensis? Let's learn about it together with Shuaishuai below!

I. Grafting Techniques for Diospyros cathayensis

1. First, let me tell you that the grafting time for Diospyros cathayensis is in early May. Early May is the best time to graft Diospyros cathayensis.

2. For stump grafting of Diospyros cathayensis, cut off all the useless branches, leaving only three to five healthy, vigorous branches. Then use a sharp cutting knife to make a split down the middle of the cross-section, with a depth of about two cm. Do not split too deep, otherwise it will damage the main trunk.

3. From a plant that has already fruited, cut off a thick branch. It is even better if the plant has axillary buds, because grafting with this kind of branch has a higher success rate. In addition, use a sterilized sharp blade to cut the bark on both sides of the base of the scion, about two cm, with a depth similar to that of the rootstock. Then insert the trimmed base of the scion into the split, and tie it tightly with a binding tape. Then put a plastic bag over it.

II. Key Technical Points of Grafting

1. It is best to choose April for grafting, because the sap of Diospyros cathayensis oxidizes very quickly. Once oxidized, it will immediately turn black. Choosing an overcast day after rain is best.

2. After grafting is completed, it is best to put a small transparent bag over it. This can prevent rain from soaking it. If it encounters water, it will die. This is something to pay attention to.

3. When cutting with a knife, do it in one go, and make any supplementary cuts precisely, with no debris. The knife must be sterilized before use. Do not touch the cut edge with your hands. After grafting, place it in a shady place, because strong sunlight will dry out its moisture and can directly scorch it to death.

The above are the grafting methods for Diospyros cathayensis. Have you all learned them? Grafting is very simple. The main thing is whether you can handle some of the details properly. The cutting is the most important part. After grafting, take extra care of it and do not let problems arise along the way.
