When does crabapple grafting have a high survival rate
The timing for grafting crabapples is generally in spring and autumn. Spring is mainly for branch grafting, while autumn is supplemented by bud grafting. The survival rate of grafting in these two seasons is relatively high. The method of crabapple grafting involves inserting the treated scion diagonally into the scion insertion hole of the rootstock, tightly binding the scion and rootstock together, wrapping them with plastic film, and watering the rootstock continuously for 5 days; once new buds grow on the scion, the plastic film can be removed.
Crabapple Grafting Time
The timing for grafting crabapples is generally in spring and autumn. Spring is mainly for branch grafting, and autumn is supplemented by bud grafting. The survival rate of grafting in these two seasons is relatively high, but the specific grafting method still needs to be chosen based on the actual situation.
Crabapples are generally grafted before the spring sprouting or in July to September of autumn, as the survival rate of grafting is higher during these two periods because the temperature is suitable for grafting, especially in spring, when everything is reviving and suitable for growth.
Grafting crabapple tree stakesMountain ash, sweet tea, apples, etc., are all suitable for grafting crabapples, and different varieties of crabapples can also be used for crabapple grafting. The seedlings obtained from the播种繁殖 of crabapple seeds serve as the rootstock for the scion connection or bud grafting.
Crabapple Grafting Method
Step 1: Rootstock treatment: Retain branches with a diameter of 6 cm or more, wrap the rootstock with gauze, remove the wounds formed after the branches are removed, wrap for 10-20 days, and change the gauze until grafting.
Step 2: Scion selection: Choose healthy and vigorous middle and upper branches as scions, trim both ends of the branches, retain 3-4 buds, and then cut the bottom end of the branch to form two diagonal faces as triangular tips.
Step 3: Scion treatment: Soak the cut end of the scion in the scion treatment solution for 4 hours, and then let the soaked scion stand for 12 hours.
Step 4: Rootstock incision: Remove the gauze from the rootstock, cut a smooth diagonal face 5 cm long 2-3 cm below the wound of the selected rootstock branch, and cut a deep 2-3 cm incision in the central part of the smooth diagonal face to form a scion insertion hole.
Step 5: Grafting treatment: Insert the treated scion diagonally into the scion insertion hole of the rootstock, tightly bind the scion and rootstock together with plastic film, and water the rootstock continuously for 5 days; once new buds grow on the scion, the plastic film can be removed.
Crabapple Post-Grafting Maintenance Tips
1. Wiping off sprouts: After crabapple grafting, pay attention to the sprouting situation of the rootstock and scion. When the new shoots of the scion grow to 10-12 cm, all sprouts except the scion can be cut off to promote scion growth. Afterward, apply a new bud every 5 days until there are no new buds on the rootstock.
2. Reinforcing treatment of the new scion: Clamps can be used around the scion to prevent the joint from loosening due to swaying in the wind. When the new shoot grows to 50 cm, remove some leaves in time to prevent the weight of the new shoot from increasing, which could lead to the scion being blown off or falling off.
3. Fertilization and water management: After 7 days of grafting, the rootstock and scion are basically healed, and the first watering begins. After 20 days, check the survival status of the grafted seedlings and water again after fertilizing.
