Grafting is a rather traumatic process for both the supporting plant and the cutting.

The first thing is to take into account in which tree you are going to graft the lemon tree. Ideally, use a tree as similar as possible, such as an orange or other citrus from a close family. If you use an orange tree, do it before autumn, so that the bark is looser and with the sap circulating more easily. The most common is to graft of a lemon tree with T-shaped incision:

  1. Prepare a knife or tool as sharp as possible and disinfect it with alcohol.
  2. Once the tool is clean, make a T-shaped cut in the rootstock, and separate the bark very carefully, trying not to break it.
  3. The green layer under the bark must be left uncovered, which is where the lemon graft should be applied, which you will have to have previously prepared and cut around the bud.
  4. The graft is fitted as close as possible to the rootstock and covered with plastic or some other protection above and below the bud to prevent insects from entering the wound or becoming infected with harmful microorganisms such as bacteria or fungi.
