I am beyond frustrated with my pineapple plants. I have like 7 of them. Five of them came from 2 store bought fruit originally. These 5 are over 3 years old now. They are huge plants.... But REFUSE to flower and fruit. I have tried everything... Potassium/ethylene water from bananas. Apple slices in the crown. Fertilized, moved to a sunnier spot, moved to a shadier spot. Still nothing... I am so tempted to just pitch them out.
