Just wait a tad longer. Give plenty of water. On average it takes 10-15 months to flower. The plant will throw out a “flag” leaf just before the bloom comes out. The flag is just a small leaf usually smaller than 24” or so. Once the flowers emerge, expect about 6 months from flag leaf to harvest. Once the bloom stops producing the banana fingers, I just cut off the Purple Heart of developing flowers to help direct growth into the fruit. In central florida, I’ve had best luck waiting until the bottom most banana fingers just starts to turn yellow on the tree. The longer left on the tree, the higher the sugar content, experienced. The bananas sliced, topped in cinnamon, and lightly fried in coconut oil in a pan on the stove top makes a great natural sugar-glazed banana snack!
