Did you know you could grow a pineapple bush from the top of a pineapple? Believe it or not it's becoming more popular. Since we can still find whole pineapples in the store with the tops still attached it's a easy project to take on.
Here are some basic steps.
Cut the top off a pineapple and remove all the fruit. If you leave any fruit on the top it will rot the top and this will not work.
Remove the bottom 1 1/2" of leaves. the stalk with root but the leaves will rot.
Dry the top of the pineapple for two days until a callous forms. Depending on the humidity this could be as short as a day or as long as a week. Do this in a cool and dry place. If you skip this step the stalk will rot.
Dip the stalk end in water and then into rooting hormone. This makes rooting faster.
Lay the stalk in a clay flowerpot of fast draining potting soil so that only part of the stalk is touching the soil. Do NOT put the entire stalk in the soil. (This means do not plant the stalk in a vertical position. If you do this then it is highly likely the stalk will rot. If you live in a dry climate like Arizona, then put the pot and stalk in a plastic bag to conserve moisture.)
Mist frequently to keep the soil moist but not wet. Roots on your pineapple bush should appear in 2 to 3 weeks.
Once roots appear, re-pot the pineapple in a vertical position into a fast growing potting soil.
Remember pineapples are actually bromeliads. Hence they like tropical conditions. High light, constant humidity and constant lite fertilizer in the summer time.
In 2 to 3 years, your pineapple bush will grow another pineapple. In order to pick a few fruits each year just replace the picked pineapple, with its top and the cycle will continue.
