Reviving a Wilting Bougainvillea After Purchase: Transplant Shock and Temperature Stress

Diagnosis

Wilting (not leaf drop) indicates water isn't moving through the plant. Causes likely include:

• Transplant shock/root stripping: Bougainvilleas have delicate root hairs; any disturbance causes wilting.
• Temperature shock: Sudden change from cool nursery to warm indoor (65→80°F) can cause vascular shutdown.
• Overwatering: Kills roots; wilting is first symptom. Phytophthora mold attacks wet roots.

Immediate Action

• Status quo: Don't repot, don't overwater, don't move.
• Water only when soil is dry; if soil is moist but plant wilts, do not water.
• Keep soil temperature stable; provide sun but avoid drastic temperature changes.
• Increase air circulation; reduce moisture to prevent mold.

Perspective

This plant is having a "bad day" from cumulative stress. Patience and minimal intervention are best.
