The Q&A Archives: Pineapple Plant

Question: 3 years ago I started a pineapple plant that is 32

Answer: Pineapples need full sun, very high humidity, and night temperatures that don't dip below 65F, to mimic the conditions of their native habitat. Pineapples will generally fruit in about 18 months although this can vary significantly due to growing conditions such as temperature, light, fertility, etc. Since your plant is over 18 months old and has not fruited, try placing an apple in the top of the plant, cover the plant with a large, clear plastic bag (like a dry cleaner bag) and poke a few holes for aeration. (Note: move the plant out of direct sun. Covering a plant in the sun with a plastic bag will "cook" it!) After about two weeks remove the apple, keep the plant well watered and wait. The ethylene gas released from the apple will usually initiate blooming. A central stalk with a miniature pineapple on the end will grow up from the plant. Continue to water well during this period. When the pineapple reaches full size and turns from greenish brown to the yellowish brown color of a ripe pineapple it is ready to be cut from the plant. Hope this works for you.
