Pineapple tops refer to the top fronds and cap portion of the fruit removed during food preparation. Pineapple tops will root and grow into unique houseplants with proper care. Some lucky gardeners might even get the plant to produce small fruit. This easy gardening project works perfectly for children or for the novice gardener to learn about rooting and transplanting houseplants. This houseplant will add beautiful foliage to your indoor container gardens.
Cut the pineapple 2 inches below the fronds straight across on a cutting board. Remove the pulp and fruit portions around the edging, leaving only the front top and the center core (stalk).
Peel back leaves at the lower portion of the leaf section to expose additional roots. This exposes the bumpy areas where new roots form.
Place the plant in a cool, dry location for two to three days to dry completely. Drying the pineapple top before planting prevents rot.
Fill a half-gallon (6-inch-by-6-inch or larger) container with perlite, an absorbent fluffy potting medium. The container must have drainage holes to allow the free flow of water through the bottom of the plant.
Place the trimmed stalk (core) into the perlite medium and fill in around the plant. Water the perlite thoroughly. Place the pineapple top in indirect bright lighting for six to eight weeks until roots form. Water regularly to create even moisture in the perlite. Perlite should be moist but not soggy at all times. Place the pineapple top in bright light indoors in a warm 70 degree Fahrenheit location.
Gently lift the pineapple top out of the perlite after six weeks. Check the stalk and base of the leaves for protruding roots about 1 inch long. If you see none, place the pineapple top back into the perlite and water thoroughly. If the stalk contains roots, it's ready to plant in potting soil.
Rinse all perlite from the pot and reuse the original container or prepare a second 6-inch pot with new potting soil. Place the pineapple top into the soil mixture. Fill in around the roots and base of the plant, allowing the leaves to sit above the soil level. Plant depth will vary but the base of the leaves should sit about 1 inch below the pot edge.
Water the pineapple plant evenly and place in a location featuring indirect light. Allow the plant to become adjusted to the soil mixture for two to three weeks and move the plant to a sunny location. Water when soil becomes slightly dry and fertilize with a water-soluble houseplant fertilizer once a month.
