Best Grafts for Tropical Fruit Trees

What Grafts to Use on Popular Tropical Fruits Like Mango, Jackfruit, and Avocado

If you are growing tropical fruit you may find you need to use grafting to reproduce trees you have, or to change an old tree or parts of it from bearing one fruit to bearing another variety.

When it comes time to do this specialty work, it’s nice to be able to learn from the efforts of professional growers that have come before us, so that you don’t have to use trial and error to find the most successful grafts to use. Here, I’ve collected some professionals’ recommendations of what grafts are most successful for some popular species of tropical fruit.

    Mango

    Veneer grafting is the most practiced in Florida. Chip budding and saddle grafting are used, and spliced approach graft is also used in India and has long traditional usage there. 

    Cleft and whip are also recommended by Campbell & Ledesma.

    Cleft, whip, side-wedge, or approach.

    Rambutan

    Approach grafting, 100% success. Approach grafting under shadecloth from a top-cut rootstock to a live plant as a scion using a (very small) cleft graft, 88% success. The other method tried, standard cleft grafting, was not more than 42% successful in trials.
