I planted my pineapple about 5 years ago from the head of a store bought pineapple and even though it hasn't died and is still growing, it hasn't got nearly big enough to produce fruit or even approached the size I've seen other planted pineapples get.
About a year ago I planted it in a new pot with fresh soil and compost, it seemed to get a little better. I noticed what looked like smallish pineapples growing near the bottom. But beside that it's mostly still the same.
I water it as often as I can remember (usually every second or so day), and keep it in full sun. Is there anything I should be doing that I'm not?
