New Arborvitae Browning: Overwatering, Nursery Care, or Planting Issues

18 new 5-ft arborvitae, several browning. Hose watered, moisture meter reads wet. What to do?

Likely Overwatering or Nursery Issues

Nursery: how long dug? Watered properly?
You may be overwatering (meter = wet)

Dowel Rod Method (Better Than Meter)

1/4–1/2″ dowels, 12–14″, sharpened
Insert in root ball, pull daily
Moist = good, wet/saturated = bad
No malfunction risk

Watering Rule

1″ rainfall/week. Deep soak, not sprinkle. Mulch 4″.
