Step-by-Step Growing Guide
Pineapples are terrestrial bromeliads that grow as rosettes and fruit only once per mother plant, then produce ratoon shoots (pups) for subsequent crops. Grow in zones 11–12 year-round outdoors or as a container plant in warmer rooms. Root the crown of a store-bought pineapple by removing the lower leaves, allowing to dry for a week, then planting in well-drained, sandy, acidic soil (pH 4.5–5.5). Position in full sun — maximum light is critical. Pineapples are surprisingly drought-tolerant with their central cup trapping water. Water by filling the central cup and lightly moistening the soil. Feed with a dilute foliar spray of liquid fertilizer monthly — they absorb nutrients through their leaves as well as roots. To force flowering on a reluctant plant, expose to ethylene gas by enclosing in a plastic bag with a ripe apple for 4–5 days. Plants take 18–24 months from rooting to first fruit.
