Cut off the leafy crown of a pineapple with a very sharp paring knife.
Remove completely any fruit from the cut side of the crown. This would rot and possibly kill the roots before the plant has a chance to establish itself.
Stand the crown upside down, cut side up, on a paper towel for 6 to 8 days to dry. Very carefully remove the lowest inch or so of leaves to expose some of the stem. Be careful not to damage the small brown buds on the stem or any of the tiny roots that may already be sprouting.
Fill an 8-inch clay pot with a mixture of soil and compost, in a ratio of 2 parts lightweight potting soil to 1 part organic compost.
Put the pineapple crown into the soil and press the soil around the base of the crown firmly. Be careful not to cover any leaves of the crown and be sure the soil does not get into its central leaves. Place the pot outside in direct sunlight.
Fill a spray bottle with water and apply a light mist to the leaves and soil mix in the pot until they are damp. The mix should be dampened once a week.
After planting, fertilize your pineapple every two or three months according to the manufacturer's instruction.
