New Hydrangea Wilting and Leaf Scorch: Transplant Shock Recovery

A hydrangea planted 3 weeks ago shows wilting blooms and scorched leaves despite fertilizer and regular watering. The gardener asks what's wrong.

Diagnosis: Transplant Shock

Common causes:

• Overwatering: "Regular watering" may mean daily, keeping soil soggy. Hydrangeas need moist, well-drained soil.
• Over-fertilizing: Fertilizer on a new plant burns roots. Use starter fertilizer (high P) or none until established.
• Sun exposure: Full sun all day can scorch a nursery-grown plant. Morning sun/afternoon shade is ideal.
• Root disturbance: Root ball may be dry or root-bound at planting.

Recovery Plan

1. Stop fertilizing.
2. Water deeply once a week (1–1.5 inches), more in heat. Check soil 2 inches down—moist, not wet.
3. Mulch 2–3 inches to conserve moisture.
4. Provide temporary shade (shade cloth) if in hot afternoon sun.
5. Remove spent blooms to reduce stress.

Soil Preference

Hydrangeas thrive in well-drained, loamy, acidic soil (pH 5.5–6.5). Amend planting area with compost if soil is heavy clay or sand.

Patience. Most recover in 4–6 weeks with proper care.
