Well, I got this idea from +Aarica Langdon on +Blythe Raw Live show a while back. I tried it last month & the poor thing didn't make it. So, I am trying 2 more. These 2 have really good roots already, so hopefully, they will grab hold of the soil well.
Make sure you get a ripe pineapple by pulling on a leaf about an inch up from the top of the pineapple. If it pulls out easily, the fruit is ripe.
Plant it in good potting soil, water thoroughly & hopefully, it will take hold and grow. It takes about 18 months for the plant to mature and bear a new pineapple.
