Growing a pineapple plant at home is a simple project for any gardener. Use the technique with students in the classroom to teach about plant structures and plant growth. It takes approximately 20 to 24 months for pineapple plants to bloom and yield fruit, according to the Pineapple Working Group in Hawaii. However, after plants reach 2 feet in height, it is possible to force bloom them for earlier fruit production. Pineapples are tropical plants and require a great deal of sunlight to thrive. The group advises alternating indoor and outdoor time (weather permitting) to give pineapple plants the best light for optimum growth.
Select a ripe pineapple from the local supermarket or fresh produce market. Make certain all leaves are green. Disregard pineapples that have yellow or brown leaves.
Stand the pineapple on a cutting surface. Remove bottom row of leaves closest to the fruit by pulling them off by hand.
Use a ruler to measure 5 inches from the base of the pineapple stem toward the fruit. Make a small dot with a permanent marker to indicate the 5-inch location. Rotate the pineapple and repeat measuring until there is a row of dots. These make the cutting line.
Lay the pineapple horizontally on the cutting surface. Insert a sharp, long-bladed knife into one of the dots previously drawn. Cut along the dotted line using a back and forth motion until the top is cut off.
Set aside the pineapple fruit. Place the pineapple top on its side to expose the fresh fruit base. Make a thin slice on the base of the top. Repeat until small white dots reveal themselves. Stop slicing when the white dots appear. These are the root nodules.
