Mandevilla Transplant Shock: Organic Soil Amendment for Recovery

Diagnosis

Brown leaf undersides on new 25-gal pot mandevilla in heat = transplant shock. Roots haven't colonized new soil; water/nutrient uptake fails. Sister's plant fine = individual variation.

Rescue

1. Organic soil treatment: Rhizofuel (rootfeed.com, ~$22) or quality compost/humus blend.
2. Apply: Work into top few inches; water in.
3. Mulch: 2–3" to conserve moisture.
4. Water: Consistent moisture (not soggy) while roots establish.

Why Organic Amendment

• Stimulates root growth.
• Improves soil structure/water holding.
• Feeds beneficial microbes.

Mandevilla recovers fast once roots engage. Heat + new pot = perfect shock storm. Organic amendment accelerates root colonization.
