Pineapple Plant Decline After Repotting: Root Rot Warning

Your pineapple (grown from a top) yellowed/browned after repotting into a larger pot with cactus mix. The diagnosis: root rot from excess soil holding water.

Why It Failed

• Pineapples have tiny root systems—must stay potbound.
• Repotting added wet soil around roots → suffocation/rot.
• Watering schedule unchanged worsened it.

Emergency Fix

1. Unpot. Remove all added soil. Check roots: firm/white = hope; mushy/brown = likely dead.
2. If healthy roots remain, repot into original small pot with original mix.
3. Water sparingly. Bright light. No fertilizer.

Correct Propagation Method

1. Root crown in water (bare stem submerged, leaves above).
2. When roots 1+ inch, pot in 4–6" clay pot with damp peat mix.
3. Water when top inch dry. Gradually increase sun.
4. Keep potbound. Fertilize half-strength in good light.

Never repot a pineapple unless the pot cracks. They thrive on neglect and tight quarters.
