Grow a pineapple from a top by allowing the top to dry out, placing it in a light soil mix, and keeping the soil moist for up to two months. Once the top roots, place the plant in bright light.

Cut off the top of a pineapple within an inch of the leaves, and set it aside for a week to give the cut time to heal and scab over. Prepare a pot with perlite, sand and potting mix. Place the top in the pot with soil coming to just below the leaves. Put the plant in a location with plenty of indirect light, and water it well. The soil needs to be moist for the first two months so that the roots develop.

Once the roots have grown into the soil, give the plant six hours of direct sunlight per day. Decrease watering so that the soil dries out between sessions. During the summer and spring, give the plant a water-soluble fertilizer once every two to four weeks. Shade the plant during part of the day during the hottest months, and bring the plant indoors during the winter. If it does not blossom after three months, lay the plant on its side to promote the production of ethylene, which in turn promotes flowering.
