1、 Grafting time

Time is an important factor in success, which can determine success or not. It can be selected in spring, that is, from March to April. At this time, the climate is very suitable. It is just in the growth period, which can improve the probability of survival. Just when everything starts to recover, it has entered the period of germination, and the incision can recover faster to ensure that it can survive later. Other seasons are not impossible, but they are not suitable. The climate in summer is hot, which is easy to breed bacteria and affect the survival rate. If it is operated in winter, the surrounding temperature is too cold, which inhibits the speed of healing

2、 Grafting method

1. Splitting: first cut the section of the rootstock with a knife, and then split it vertically. It doesn't need to be too deep. It can be kept at a depth of about 4-5cm. Cut off the strong scion, cut the lower end into a wedge, then pry the cutting edge of the rootstock with the back of the knife, insert the scion, put a plastic bag on the outside and tie it tightly, which can improve the survival rate

2. Subcutaneous branch connection: first select the position on the rootstock and choose the smooth and flat side as much as possible. Use a knife to make a cut, and then use the blade to gently pry open the bark, cut it, insert it inside, and wrap it tightly outside
