The pineapple is the quintessential tropical fruit, and its prickly plant and fruit--the fruit rises from the center of the plant on a long stick--can make an excellent conversation starter. Pineapples can be grown outdoors in USDA hardiness zones 9 through 11, or indoors in a pot. Wherever you grow your pineapple, you'll be happy to know that pineapples require very little water and can be prime for xeriscaping.
Get the pineapple ready for planting. If you already have a prepared pineapple crown from a garden store or nursery, skip to Step 2. Grasp the pineapple fruit in one hand and the base of its crown--the prickly leaf structure at the top of the pineapple--in the other hand. Twist the crown to pull it out of the fruit. Cut away any pieces of fruit still attached to the crown, and set the crown on your countertop for five days to dry.
Prepare the soil. If you're growing the pineapple outside, select a sandy loam patch that receives a minimum of 7 hours of sunlight per day. If your garden has no such area, use a standard gallon-sized plant pot. Add an inch of gravel at the bottom to assist with water drainage, then top it off with a commercially prepared potting mix.
Plant the pineapple. Sink the base of the pineapple crown into the dirt to a depth so that its prickly leaves meet the soil.
Water the pineapple plant. Water daily to keep the soil moist until new growth emerges from the top of the pineapple crown. This signifies that the plant has taken root. After that, reduce the watering to approximately 1/2 inch of water once a week.
