Most of the Keitt trees I've encountered have been healthy, but I live less than a mile from the ocean. It's still the favorite late mango, evidenced by the fact that there are four (I'm revising that from 3) trees in the neighborhood planted in the front yards of three houses in the past three years. I'm sure that none of these neighbors have ever heard of Tropical Fruit Forum or of Sweet Tart, Lemon Zest, Mahachanok, Fruit Punch, Edgar, etc. One guy has a Haden, a Julie, a Glenn, and 2 Keitts, all in his front yard.
