How to Propagate Pineapple From Seeds

Collect the small, kidney-shaped beans from a mature pineapple by slicing the fruit into 1/2-inch slices. You will typically find the black seeds toward the bottom of the pineapple and you'll want to wash the fruity flesh and juice off the seeds before germinating them.

Sprout your pineapple seeds by placing them in a covered, sterile glass container and storing them in a warm place out of direct sunlight. Pineapple seeds typically take several weeks, sometimes up to six months, to produce small white shoots, which are the roots and then later green shoots, which are the plant.

Transplant individual sprouted pineapple seeds into their own soil-filled pot when the roots have reached about an inch in length. Cover pineapple seeds with soil, but leave the young, fragile shoots above the soil. You may also want to cover your young seedling with a small plastic dome to keep the atmosphere humid and moist, like the pineapple's natural tropical environment.

Care for you pineapple seedling and watch it grow, and in a couple of years it may produce a tasty, tropical fruit. Pineapple plants need watering about once a week and fertilize it as you see fit. Peel away dead or damaged leaves to maintain your pineapple plant's health and appearance, and keep repotting it as it grows to give it more space.
