I started a pineapple plant at from the top of a pineapple it is approximately 3 years old it does bad in the winter time but it always pops back in the summer we live in Illinois my question is how long does it take to actually get a pineapple off of the pineapple plant

Depending on the cultivar, pineapple plant takes 2-3 years after root formation to fruit. That it does poorly in winter indicates you need to change your care. Only a very healthy plant has the energy to produce fruit. Pineapple is a tropical plant and needs to have moist, yet fast-draining soil. Do not let it dry out and do not let it sit in water. To ensure good drainage, add some sand, perlite or cactus mix to regular potting mix. It requires supplemental light in Chicago winters. This article gives a tip to trick the plant into fruiting. I hope it works for you. https://www.gardeningknowhow.com/special/children/planting-pineapple-tops.htm
