1、 Grafting method

1. Time: different regions have different grafting times. The area to the south of the Yangtze River is from mid April to late October. The climate to the north of the Yangtze River is colder. It can be selected from mid May to late September. The spring and autumn season is the most suitable

2. Rootstock: the best rootstock for grafting is wild rose. Its root system is relatively developed and has strong disease resistance. The survival rate of grafting with it is high

3. Scion: the most commonly used method of budding is relatively simple to operate. First select the scion, cut the strong branches from the plant, take out the branches and buds from the middle part, and draw them from 1cm to 3cm above the buds

4. Grafting: select the smoother side of the branch, cut it and tilt it downward. Be careful not to cut it off. Aim the branches and buds at this interface, put them in and wrap them in plastic bags

2、 After management

1. Pruning: in order to ensure the growth of the grafted bud, the top of the lateral branch is toppled one week after grafting, which can promote the plumpness of the plant

2. Untie: when the new bud grows to about 10-15cm, remove the plastic bag bound on it

3. Water and fertilizer: after the plant survives, water and fertilizer can be applied appropriately to ensure the nutritional needs of the plant
