When to graft bayberry? Detailed explanation of grafting time and methods
Grafting is a common planting technique in our lives; many fruit trees use it to improve survival rates and achieve high and quality yields. Bayberry is a specialty fruit of southern China. In the past, its survival rate during planting was relatively low, but later, after using grafting methods, the survival rate of young trees was greatly improved. So how should bayberry be grafted? What is the specific operation method? Below, Qinnong Network brings you the grafting time and methods for bayberry. Let's take a look.
1. Grafting time
The suitable grafting time is a period with mild temperature, neither too low nor too high, generally from February to March, and at the latest it must not exceed Qingming Festival, otherwise the air humidity is relatively high, which will cause excessive bleeding and grafting failure. Moreover, at this time bayberry has already begun to sprout, and the bark and woody tissue have also formed and become hard and brittle. In warmer southern regions, it can be appropriately advanced to January to February.
2. Grafting methods
Select strong-growing, disease-free plants, cut off the current year's shoots to serve as scions, remove the leaves, and place them in a cool, moist place for later use. Cut away the bark at the wounded section of the scion, then cut the bottom end into a wedge shape. At a position 8-10 cm above the ground on the rootstock, choose a smooth, flat part, cut off the rootstock, smooth the wound, and then make a vertical cut in the middle of the wound, with a depth equal to the wedge-shaped part of the scion. Then insert the scion into the rootstock incision. Note that it should not be inserted completely; leave a length of 0.5-1 cm so that the incision is closely connected. Then tie the incision tightly with plastic film, fasten it, and keep it moist.
3. Management after grafting
If the rootstock sprouts within one month after grafting, remove the sprouts in time, as this helps the scion survive. After grafting, if there is excessive bleeding or if it is rainy, puncture the wrapping film to release water. After successful grafting, when new buds sprout, remove the film in time and pinch off the growing tips, leaving 2-3 stronger shoots. When they grow to a certain length, repeatedly pinch off the growing tips, which can speed up the formation of the tree crown. In summer and winter, whitewash the trunks of young trees, which can prevent sunscald and freezing injury.
