I think more trees out in the country and every things has a peak season. Soursop I have acquired a taste for it was a very wierd flavor at first but the juice refreshing. Still my mouth freaks out a likkle though LOL. Love guinup....lotsaround but they seem pretty dry on the outside so must be season ending for them. Also you can find more as you know on Market Days in Sav, Lucea, etc. where they have more variety.
