Many growers in Florida would never plant Manzano due to suseptibility to Panama disease......is this a potential concern for you?

I know this is the reason Going Bananas has never carried them:

If so grow Brazilian...I love Manzanos..(more so than Braz...not as sweet with a "sub-acid flavor") I occasionally buy them at the local Spanish markets..just have never grown them (I grow Brazilians)...
