Gardeners living in USDA zones 10 and 11 have the option of growing pineapple plants in an outdoor growing area. Because pineapple plants grow exceedingly well with little coaxing or intervention, planting a pineapple crown in a sunny location will often yield a delicious pineapple fruit. Pineapple plants grow and produce fruit slowly, often requiring between one and two years to produce a pineapple for harvest. Once your pineapple begins to mature, make sure you know when a pineapple is ripe and ready to pick from the plant to ensure the sweetest pineapple.
Watch the pineapple as it develops on the plant. Approximately four months after the plant flowers, the growing pineapple will begin maturing for harvest.
Notice the underlying green hue of the pineapple slowly begin to change at the bottom of the pineapple first. Over a period of one to two weeks, the pineapple will turn yellow at the bottom and gradually the yellow color will spread upward through the fruit.
Wait to pick the pineapple until the yellow color covers at least half of the pineapple. The more yellow the pineapple, the sweeter the flesh. Wait longer for the pineapple to turn more yellow in color, if you wish.
Clip the pineapple from the plant, using the pruning shears, when you want to harvest it.
