Water well and allow the pot to drain. Place the pot in a heated propagator or in a warm, bright spot indoors, until roots have developed. New leaves will soon form in the centre of the rosette. Once roots start growing from the base of the pot, transplant your pineapple into a larger container. Keep the plant in a warm conservatory or greenhouse, or on a window sill, and continue feeding and watering regularly, potting on as required.
