How to Make a Pineapple Plant Fruit

Although most people think of Hawaii when they think of pineapples, the fruit actually developed in the Caribbean and Central America. Pineapples are a bromeliad that is distantly related to Spanish moss. Pineapples are used in tropical areas of Florida, California and southern Texas as a landscaping plant, where they produce a whorl of leaves that may span as much as 6 feet in diameter. When a pineapple reaches maturity, it produces a fruiting cluster of flowers on a stem. If your plant has not yet produced a new pineapple, you can force it to produce fruit.

Calcium Carbide

Leave a potted pineapple outdoors as fall approaches. Cooler weather and shorter days naturally induce the fruiting cycle in a pineapple plant.

Purchase calcium carbide tablets in a hobby or craft store.

Drop 4 tablets in a glass of ice water and allow it to dissolve.

Pour the solution into the center of the pineapple rosette once the solution stops bubbling.

Add fresh solution one week later.

Ethylene Gas

Place a large freezer bag over your pineapple plant.

Slip an apple into the bag with your plant.

Place the potted plant in the shade for three to four days.

Remove the bag, retrieve the apple and move the plant back into the sunlight. The ethylene gas released by the apple should induce the plant to flower, though according to horticulturalists from Texas A&M University Extension, it will take "a few months" for the flower to appear.

Times Does A Pineapple Plant Fruit?

The deep green, strap-like leaves and size of a pineapple plant (Ananas comosus) makes it a striking addition to a potted garden or outside in the garden in frost-free climates. The plants can take a long time to flower and set fruit, and they are only capable of producing a few edible fruits before the vigor of the plant begins to decline. Each flower stalk produced by a plant has the capability of setting fruit. The mother plant, or the first plant grown, produces a single fruit from the center of the crown. Ethylene gas, produced by both calcium carbide and apples, forces flowering. In large containers you can leave these shoots, or suckers, on the mother to continue growing. The time from initial planting to fruit set varies. The type of planting also impacts the time to first fruit.


It takes six months for a pineapple fruit to fully develop.
