Propagating Ornamental Pineapple: Top Cutting and Mother Plant Care

How to Grow a New Pineapple Plant from the Fruit Top

After an ornamental pineapple (Ananas comosus var.) fruits, the mother plant declines, but you can propagate the top (crown) and sometimes get a side shoot from the base.

Rooting the Crown

1. Cut the leafy top off the fruit, leaving ~1 inch of fruit flesh.
2. Remove lower leaves to expose ~1 inch of stem; you'll see small root primordia (bumps).
3. Let the cut end dry (callous) for 2–3 days in a shaded spot.
4. Plant in a small pot with well-draining mix (cactus soil or peat/perlite).
5. Keep barely moist; place in bright indirect light.
6. Roots form in 4–8 weeks. Tug gently to test.

Mother Plant After Fruiting

• Bromeliads are monocarpic—the flowering rosette dies after fruiting.
• However, it often produces offsets (pups) at the base before dying.
• Leave the mother plant in bright light; water when top soil is dry.
• When pups are 1/3 the mother's size, they can be separated and potted.

Key Fact

Pineapples are full-sun plants. Even indoors, they need the brightest possible light (south window or grow lights) to thrive and produce pups.
