Split graft for citrus fruits: how to graft lemon, orange and other citrus fruits using the split grafting technique. Moon, period and useful tips to increase the chances of engraftment.
We have already talked about the methods of propagation of citrus fruits and among the most effective ones, we have reported thegrafting; a grafting technique particularly suitable for the propagation of citrus fruits is grafting split. In this guide we will provide you with all the instructions on when and how to perform asplit grafton the plants ofcitrus fruits. From the best time to pick up the scions to advice on rootstock.
We remind you that thesplit graft it is not the only method of propagating citrus fruits; whoever wants can perform other types of grafting, sowing, layering or multiplying citrus fruit by cutting. If, with the cutting and layering, a specimen identical to the mother plant is obtained, with thegraftingit will be possible to obtain a more robust, resistant and long-lived plant.
Sowing also has several advantages but, sometimes, it may be necessary graft the citrus plant made to sprout and grow from the seed. If you want to grow a lemon plant starting from the seed, the guide might be useful:like sowing a lemon tree.
What type of graft to use for citrus fruits?
The techniques ofgraftingused with citrus fruits are thesplit graft, the crown graft and the vegetative bud graft. L'split graftit is probably the simplest to perform and offers excellent opportunities for engraftment.
Citrus split graft or interlocking graft
L'graftingis a very effective method of propagation as it is possible to obtain a more robust and long-lived specimen, the result of the union of two plants: one provides the root system and is calledrootstock, while the other, called scion or nesto, develops the crown.
L'split graftit is performed on a rootstock that must not exceed 10 millimeters in diameter. After cutting the rootstock at the desired height for the plant (a dry cut horizontally), a vertical cut can be made that precisely goes tobreakin two the rootstock for a depth of about 3 centimeters.
Prepare the scion so that the tip is the same length as the cut engraved in the rootstock. The scion cut must be complementary to the split made in the rootstock. Due to this characteristic, thesplit graftit is also calledinterlocking coupling.
Insert the scion into the rootstock and tie the graft with raffia and seal with elastic insulating tape. To encourage rooting, it is possible to spread mastic for grafts, this prevents the development of fungal diseases and the entry of water into the affected area, preventing molds and rot that could irreversibly compromise your work.
Split grafting Citrus fruits: period and moon
The best period to practice split grafting for a citrus plant (orange, lemon, mandarin ...) is from April to May. As for the moon, old moon is chosen.

Interlocking or split grafting of citrus fruits, tips on rootstock
The mother plant or rootstock, before being carved and grafted, it will have to be cleaned of the shoots and twigs at the base. Also eliminate the suckers which are those lateral jets placed at the base of the plants, very abundant right in the citrus fruitsand in other wood species. The suckers tend to steal lymph and energy from the plant by subtracting the energy that your rootstock could use for the grafting of the scion. The removal of suckers and shoots must be performed before grafting. In the period after grafting, monitor the rootstock and eliminate any lateral jets and suckers that may arise after grafting.
