What rootstock is used for grafting crabapple?

1. What to use

1. Seedlings: Seedlings propagated by sowing can be used as rootstocks. This has a higher affinity and there is no need to worry about rejection. It is conducive to healing between the two, can ensure a higher survival rate, and the root system is relatively developed.

2. Hawthorn tree: It is an excellent rootstock with strong cold resistance. Some varieties can withstand temperatures as low as minus 50 degrees Celsius. Using it as a rootstock can improve its cold resistance and avoid frost damage. It also has strong adaptability and can grow in poor loam. It has deep roots and is relatively strong and tenacious.

2. Grafting method

1. Time: The time of grafting depends on the grafting method. If it is branch grafting, it can be done in spring before budding. If bud grafting is chosen, it can be done around July to September in autumn.

2. Scion: The selected scion can be one-year-old branches, and more than two full buds can be cut. This can increase the survival rate. An incision is cut at the bottom, and it must be flat.

3. Grafting: Bud grafting often uses the "T" grafting method, where the cut buds are inserted into the rootstock and then tied tightly from the outside to fix it.
