Pineapple plants are some of the easiest plants to grow either indoors or outdoors. Unlike other fruit-bearing plants, pineapple plants can survive easily in a self-contained pot and do not grow to be very large. Though they don't bear fruit very often (once or twice a year you will get a pineapple, at best), the pineapple plant is easy to grow in any temperate climate.
Twist the top off the pineapple firmly. There should be no fruit attached, only a thick green stalk with some pointy leaves.
Strip the lower leaves, and expose about an inch of the bottom of the crown. You will see several small brown-coloured bumps below the leaf scars. These are root starters and will help your plant take root in its new pot quickly. Do not damage these.
Let the partially stripped stalk sit for several days so that it can dry out. Then fill a small bowl with water and let it sit for up to two weeks. Make sure to change the water often. After two weeks, you should have decent root growth. During this time, take care not to expose the plant to extreme temperatures.
Fill a 12-inch pot with soil and then transfer the pineapple from the water dish to the dirt, making sure to completely cover all roots. You may then place the pineapple in a sunny area (like a window) indoors or on a porch. If you live in an area that is warm year-round, you can put the plant outside in a garden.
Water the plant at least twice a week and remove any leaves that brown as soon as possible. Fertilise the pineapple plant at least once a month. After a year your plant will reach maturity and then in two you should see your first fruit flower.
Be careful not to overwater your pineapple plant because this can cause root rot, which will kill your pineapple plant.
