Leyland Cypress Summer Planting Shock: Mulch, Deep Watering, and Guarantee Leverage

Diagnosis: Transplant Shock + Heat Stress

August planting + daily watering = root suffocation + heat stress. Browning from top down = classic shock pattern.

Recovery Protocol

1. Mulch 3″ organic (pine straw), not touching trunks.
2. Deep water: 1″ every 3 days × 1 month, then weekly (pan test).
3. No fertilizer.
4. Expect ragged appearance through fall; new growth next spring = recovery.

Guarantee Strategy

• Ask installer: "What's the guarantee period?"
• Document with dated photos.
• Near guarantee expiry: if trees still declining, demand replacement.
• Insist replacements be planted in FALL.

Why Summer Planting Fails

Roots can't establish fast enough to support canopy in heat. Fall/spring = 2–3× survival rate.
