Martin county is south Florida and they fruit here in one year. I have some small trees and they are starting to fruit. I sold all the nice trees to Fruitscapes they will be there next week. What I have left needs to put out some new growth. I will try to post picture tomorrow having trouble posting picture on this site
While there is no official definition, South Florida is generally recognized as Miami-Dade, Broward and Palm Beach Counties. Martin County, part of the Treasure Coast, has for the most part different climatic conditions than Counties Soyth of there. While Che will grow in the Southern areas, I say good luck fruiting it in the Southern areas.
Just cause Fruitscapes purchased them does not have any bearing on anything. He sells tree to nurseries to the North of him (including Top Tropicals which everyone knows ships "their" "certified" trees all over the Country) plus once you get iff Pine Island, the climate also chsnges.
