How to graft persimmon? The latest grafting techniques and methods tutorial

Persimmon is a relatively common fruit tree for us; friends in rural areas will see it often, and basically every household will plant one or two. When the persimmons ripen, the fiery red persimmon fruits hanging on the tree look very beautiful. When growing persimmons, in order to cultivate strong seedlings and increase yield, grafting techniques are often used, so how should persimmons be grafted? Let us learn about it together.

1. Grafting time

There are many grafting methods for persimmon, and different grafting methods have different grafting times. Cleft grafting is suitable in March to April, when the buds have already begun to swell, the rootstock sap has begun to flow, and the scion is in the dormant and swelling stage, which helps increase the grafting survival rate. Bud grafting has two suitable grafting times each year: one at the transition between spring and summer, in May when persimmons bloom; the second at the transition between summer and autumn, preferably in August when the autumn shoots begin to stop growing.

2. Branch grafting method

Branch grafting uses perennial, robustly growing, well-developed vegetative branches or fruiting branches as the scion, and it can be further divided into cleft grafting, bark grafting, and so on. Cleft grafting is suitable when the rootstock is thick; at 5-10 cm from the ground on the rootstock, choose a smooth and straight spot and cut it off, use a knife to split a narrow gap 3 cm deep in the middle, cut the lower end of the scion into a wedge shape, requiring the scion to carry 2-3 plump growing buds, insert it into the narrow gap, and align the cambium layers of the two. Bark grafting is generally carried out after the rootstock bark slips; choose a smooth spot on the rootstock bark and cut it off, make a vertical cut through the bark on one side down to the xylem, twist the knife left and right, so that part of the bark lifts up, cut the scion into a horseshoe shape, and insert it under the bark.

3. Bud grafting method

The bud grafting method uses plump, un-sprouted buds on one-year-old branches as the grafting buds; commonly used forms are the T-shape and the I-shape. For the T-shape, at 3-5 cm from the ground on the rootstock, make a T-shaped cut deep to the xylem, then take a shield-shaped leaf piece about 2 cm long and 0.6 cm wide from the scion and insert it. For the I-shape, cut an I-shaped slit about 2 cm long and 1.5 cm wide on a smooth part of the rootstock, cut a rectangular bud piece from the scion equal in length to the rootstock cut, insert it into the slit, then wrap the bud piece with the rootstock bark, remove excess rootstock bark, expose the bud, and tie it with plastic film.

4. Precautions

The persimmon plant contains an alkaline substance called tannin, which oxidizes very easily when it meets oxygen, causing wounds to turn yellow and black, so when grafting, it must be done by an experienced person. In order to avoid wound oxidation, proper handling must be done to prevent grafting failure.
