i have a few pineapple plants i started from the crowns of pineapples i bought at the grocery store. they have grown well here and made pretty nice plants. I'm wondering if anyone else has had success getting a pineapple plant to fruit. Supposedly, ethylene produced from rotting apples and other fruits will cause bromeliads to flower. since the pineapple is in the family bromeliaceae it stands to reason that it should cause pineapples to flower and fruit as well. Does anyone know any other tricks?
