My 6 year old son and I planted a pineapple top in some dirt for a fun experiment, and BEHOLD...it took root! My grandmother was an old-school Floridian gardener with the greenest thumb I've ever seen. She did the overripe apple in a grocery bag trick and made all her bromeliads bloom. The apple trick works. We started the plant in Northern VA...upstairs in a toasty bedroom during the depressing winter doldrums up there...then we moved to south FL and by goodness that pineapple was NOT staying behind if my son had anything to do with it! We got a pineapple after a little over a year of growth, and it ripened in an additional 4 months. It was very small but sweet.
