Yes, it's true. Keep it warm through the winter, and feed it pretty generously. Usually, the larger the plant, the larger the fruit that it will produce. If you get it to produce fruit in less than 2 years, you're doing pretty well!

search this forum there are tons of information posted about PINEAPPPLE

I, like you, planted the crown from a grocery store pineapple. It took two years, and plant grew three feet across, but it produced a fantastic fruit and several off-shoots for further propagation. Pineapples require patience....wait 'til it blooms, the fruit takes several months to ripen. One day it will start to turn from green to gold....it will drive you crazy. LOL

Good luck.

I've been gowing pineapples for about 10 years. I'm no pro, just a hobbyist, but I get fruit every year.

In South Florida, I get blooms somewhere between December and January. The fruit sets within a few weeks, and we have golden pineapples in July.

If I don't see a blossom by Christmas, here's my trick, and it always works on plants that are at least 2 years old:

1) Trim off the bottom leaves. I take of the 10 or 15 oldest bottom leaves. This seems to direct more energy to the center of the plat and shock it a little.

2) Use a high-phosphorus fertilizer after you trim the plant. I use a standard liquid 15-30-15 and give a very haelthy dose to the plant. Then, it stays in full sun with only occasional watering. Bloom usually shows up withina month.

I've also learned a TON from this Hawaiian page:

Good luck!
