One way of inarching a citrus tree is to connect a second rootstock directly to the main rootstock instead of the scion. The scion, therefore, is budded onto the main rootstock and the second rootstock is utilized as an auxiliary to the main one. An example of the method can be seen in the top figure of the gallery on the left.

     The first results of this type of inarching have been excellent. The plants are Valencia on Swingle citrumelo with rangpur lime (limao cravo) as the inarch. The figures in the lower part of the gallery show the rootstock unions and a tree at 3 years of age.

     The main rootstock in this type of inarching should be the one resistant to diseases, for instance, Swingle citrumelo, while rangpur lime is indicated as the inarch to contribute with vigor, precocity, productivity, and drought resistance. This method is called "SLAVE STOCK" in our nursery since the second-rootstock's main function is to help the primary rootstock.
