The spiky shape of the pineapple plant makes it a conversation-starting focal plant. Its compact nature also makes it ideal as a potted plant. Start and grow a pineapple plant from a fruit obtained from your grocery store to add a tropical element to your potted plant collection. Though it may take several years for your plant to grow a fruit of its own, you can enjoy its low-maintenance prickly foliage for its own sake.
Cut off the top inch of the pineapple fruit with the prickly top still intact. Slice off the fruit from the top's stem with a knife. Set the top aside to dry for 48 hours.
Get a gallon-sized pot ready for planting during this waiting time. Place an inch of gravel at the bottom of the pot. Fill the rest of the pot with an equal mixture of sand or perlite and traditional potting soil.
Plant the pineapple when the 48 hours is up. Bury the pineapple top so that its bare stem is in the soil and its bottom leaves are resting on the surface of the potting mix.
Water the pineapple twice daily with enough water to keep the top 3 inches of soil moist. The pineapple will begin growing within two months, signaled by new leaves sprouting from the pineapple top.
Reduce the amount of water you're providing once the top starts growing. Supply approximately 1/2 inch of water weekly.
Pineapple plants thrive on low water and may actually rot or experience root problems if watered too much.
Fertilize the pineapple. Use a standard 10-10-10 garden fertilizer, applied at the rate listed on the fertilizer's label as potency varies by product. Fertilize once every eight to 10 weeks once the pineapple top starts growing.
