Plant them in sandy, medium loam soil with a pH of 4.5-5.5. Plant slips or suckers about 30 cm apart with 60 cm between rows if you will grow your plant to produce fruits. Use a general purpose fertilizer at intervals of 2 to 3 months at a rate of 50 g per plant. Water plants regularly in dry weather and apply an organic mulch to conserve soil moisture. If you live in a colder area grow you pineapple under cover making sure to maintain the temperature to at least 20 Celsius degrees (68 F) and the humidity to about 70 per cent.
Although the pineapple is an attractive houseplant, most peoples want their plant to flower and fruit. In the wild, the pineapple crown takes about 20 months to produce a ripe fruit, but your plant may need a longer time. The right size for the pineapple plant to start flowering is about 60-70 cm tall and at least 12-14 months old. An inflorescence bud will begin to form in the center of the leaves, but you will not be able to see the developing fruit until about two months later when a bright red cone emerges.
You can start harvesting your fruits when they are golden half way up. This will happen when the fruits are about six months old, about four months after flowering has occurred. The color of the shell changes from green to rich gold. The color change of the shell occurs first at the bottom of the fruit and moves upwards. During this change, the fruit becomes sweeter and the color of the flesh changes from white to yellow.
Propagation is simple. Use the terminal crown shoot as a cutting. Remove it with about 1 cm of the fruit attached. Also you can use slips or suckers that develop from below the fruit or suckers produced in the leaf axils. Dip the cut surface in fungicide and leave them to dry for several days. Remove the lower leaves and insert the cuttings in pots of sandy compost. Pot them on into 15 cm pots when rooted.
