Saving Wilting Mandevilla: Shade, Soil, and Plastic Pot Liners

Diagnosing the Wilt

Jeni's Mandevilla vines wilted despite moist soil and morning sun. The culprit? Plastic pot liners retaining excess water, causing root rot. Both plants declined, confirming a systemic issue.

Immediate Rescue Steps

1. Remove plastic liners immediately.
2. Move plants to bright shade (no direct sun).
3. Allow soil to dry nearly completely.
4. Water only when a skewer inserted to the bottom comes out dry.
5. Apply a systemic fungicide if rot is advanced.

Long-Term Care

• Use pots with drainage holes; no liners.
• Provide morning sun, afternoon shade.
• Mist foliage in hot weather for humidity.
• Fertilize biweekly with bloom-boosting formula.
• Acclimate gradually to brighter light once recovered.

Why Plastic Liners Harm

They create a perched water table, suffocating roots. Even with drainage holes in the outer pot, the liner traps moisture. Always plant directly into well-draining mix in a pot with holes.
