Pineapples are tropical plants that originated in Brazil and Paraguay. The pineapple is a member of the bromeliad family, and has the same cascading leaf spray that most bromeliads do. The fruit of the pineapple has a spiny, rough exterior. The fruit's yellow flesh is sweet and nutritious. You can remove the stem of any pineapple and plant it to grow into another pineapple plant.
Purchase a pineapple that is not overripe. To test for ripeness, pull one of the leaves in the pineapple's stem. If the leaf pulls out easily, the pineapple is too ripe. Choose one that holds tight to its leaves when they are pulled.
Use a sharp knife to remove the crown (top) of the pineapple. Remove the entire stem plus an inch or so of the top of the fruit. Use a spoon to carefully scrape out the flesh from the crown. Any flesh left in the crown will rot and attract insects.
Cut very thin slices off of the bottom of the crown until you see circles on the surface. These circles are rudimentary root structures, which develop into root systems. Once the circles are visible, there is no need to slice any more.
Fill a flower pot with potting mix. Water with a watering can to moisten the potting mix throughout.
Place the pineapple stem on top of the potting mix. Gently but firmly wiggle the stem until the crown is beneath the surface of the soil. Allow only the stem to protrude from the soil line.
Place the flower pot in an area of your yard that gets at least 8 hours of full sunlight. Keep the soil moist, but not wet. The plant will grow for two to three years before it grows a new pineapple.
In gardening zones where winters are harsh, bring pineapple plants indoors to protect them from icy weather. Treat the plant like other bromeliads: provide at least eight hours of artificial light, and mist the leaves with water every other day. Take the plant back outside in spring, after the last threat of frost has passed.
