Marsin..I had a look on google and found this.
My pineapple is 3years old and has never fruited,so I put the pot in a
grocery bag,then put ten apples in it,I tied the bag tight round the bottom,
I didn't have a clear bag big enough for the entire plant,so wasn't sure this
would work or not,I left it for about 3 weeks the took the plant and
discarded the apples about a month later I have Pineapple fruit form.
But Marsin,I have also read that if you put a couple of apples on the soil of your
plant the ethylene gasses will spurt it into life..anyway good luck.
