Pineapples are hardy plants that like warm weather and good soil that is well composted. There are three ways to plant pineapples: from seed, from suckers and from the crown of the pineapple. The crown and suckers are planted in almost the same manner, but the seeds will require more attention.
Planting a Pineapple crown
A Pineapple crown is the leafy top of a pineapple like the ones that can be purchased in the local grocery stores. To remove the crown, twist the top and the crown will separate from the pineapple, leaving a cone shape at the base. Be careful not to get cut when twisting the top off, it is pointed and sharp. A good pair of gloves will help in this step of removing the top. At this point, take time to cut away any fruit that is attached to the bottom of the crown. Any excess fruit will damage the crown roots and they will rot. causing the plant to die. Next, pull off the bottom one or two inches of leaves, but be careful not to tear the plant base while doing this. When done, the pineapple will have a root base with a couple of inches above it for a stem. The roots should already be forming and look like little pimples in between the leaves that were removed. The pineapple is now ready to plant. Place it in a pot with some good planting compost and it will start rooting in about a week to ten days.
Planting pineapple slips or suckers
Pineapple suckers are also called slips, and they grow from the pineapple after the fruit has been picked. Pineapples only grow one fruit per plant, then their life has served its purpose and they die off. After the plants die they are left in the ground for a month or two and the suckers will grow from them. The suckers can either grow from the base of the pineapple or they can grow in between the leaves near the base. When suckers are about one foot tall, they can be cut from the mother plant and rooted in the same manner as the crowns. Just remove some of the leaves to make a stem and they can be planted directly in compost in the ground.
Pineapple seeds take patience because they take a long time to germinate, as well as they need a moist environment. The seeds of the pineapple are very small and black. They can be found in the base of the pineapple fruit when it is cut open. The best way to try to get them to germinate is to place them in a small pot with potting soil, then place the pot inside a small, plastic freezer bag. This will create a small greenhouse for the seeds to live and grow in. They need to be kept in a warm location with plenty of moisture until they germinate. This process can take several weeks, or even months, before germination takes place.
Pineapples are a very hardy plant, but in most locations, it is too cold for them to grow. In these locations, they make a very good house plant in the winter and can be placed back outside in the spring and summer months. Growing a pineapple can take from 1 1/2 to 3 years to grow just one pineapple fruit, so patience is a necessity with them.
