To propagate a pinapple
plant, use a fresh pineapple that has healthy leaves on the crown. Twist or cut off the crown (leafy stem) just above the fleshy part of the fruit. Strip away the leaves from the lower inch of the crown. Place the crown in a narrow vase or glass filled with water that will allow the bare stem to stay in contact with the water, but hold the leaves above the water. Place it in a bright spot that is protected from direct sun. Keep the water level in contact with the bare stem at all times. Change the water weekly.
Roots usually appear within a week or two. When the roots are an inch or more long, then put it into a 4 or 6-inch clay pot using a damp soil less, peat-based potting mix. Water thoroughly whenever the top inch of soil feels dry. Gradually increase the light so that it ends up on a sunny windowsill.
Pineapple
plants do best in direct sun and warm temperatures (above 60 degrees). If you move yours outside in the summer, introduce it to direct sun gradually over the course of two weeks. You can increase the chance for flowering by keeping it quite potbound in a peat-based potting mix. Water thoroughly whenever the top inch of soil feels dry. Fertilize regularly at half strength when it is in good light and
growing vigorously.
