I have learned a lot from this forum, also learned from my own mistakes. After loosing numerous trees, I am at a point that my mangoes are doing well. Most of my mangoes are on Florida rootstock except for some multigrafted varieties I want on a single tree. Like this 4in1on Manilla rootstock (LZ, PPK, Juicy Peach and Maha) courtesy of Frank. Note, I am going by the fruit sizes in determining what is an early and late variety in my yard. I am in zone 9B and I do get some below 32F nights once in a while, but last year the lowest was 34.2F according to my weather station.
4in1on Manilla rootstock.

Early Varieties Orange Sherbet and Cat Saigon.


Late Varieties.
Sweet Tart and Dwarf Hawaiian on Corriente rootstock.

Icecream on Turpentine.

Lemon Zest on Turpentine.

Mallika on Turpentine.

Peach Cobbler on Turpentine.

Pickering on Turpentine.

Buttercream on Turpentine.

Carrie on Turpentine.

Some of my grafting work based on Har's top 5.

Others like Coconut Cream, PPK, Fruit Punch, Fairchild didn't flower for me this year, or aborted their fruitlets. So mangoes will grow here, don't give up!
