Emerald Green Arborvitae Establishment Watering Protocol

Newly planted 6-foot Emerald Green arborvitae (Thuja occidentalis 'Smaragd') need precise watering for survival — 1 inch per week via soaker hose until ground freezes.

Watering Schedule

• Frequency: Weekly (1 inch per application).
• Method: Soaker hose along row — ideal for even distribution.
• Duration: Run until 1 inch collects in rain gauge (typically 30-60 minutes).
• Winter: Continue until ground freezes solid (not just first frost).
• Year 2+: Reduce to drought periods only.

Why Winter Watering Matters

• Evergreens transpire all winter — frozen ground prevents uptake.
• Fall hydration = winter survival insurance.
• First year is critical — root system not yet established.

Monitoring

• Check soil moisture at 6-inch depth weekly.
• Watch for interior browning (drought stress indicator).
• Adjust for rainfall — don't water before/after heavy rain.

Consistent deep watering the first year = decades of trouble-free hedge. Skimping = replacement costs.
