If you keep it warm all year long and feed it well then it should fruit in 2 years.
That's the bad thing about growing pineapple in a place that gets cold is that it will force
the plant to flower to soon alot of times it never gets a chance to reach two years of growth
the part of florida I'm in gets cold but not that bad but a few of my pineapple plant varieties
i grow always seem to flower way to soon around a years worth of growth but i still end up
with a great tasting pineapple...if i had only a few plants i would try moving them inside
but i have way to many plants to have to move lol
