Common problems on the Front Range
- Mountain pine beetle in drought-stressed pines
- Pine wilt nematode (esp. Scots and Austrian pine)
- Pine needle scale
These are general tendencies for this group of plants on the Front Range, not a diagnosis. Many are stress-driven and preventable with good siting and watering. For a specific plant or an active problem, consult a certified arborist or your local CSU Extension office.
Planting & establishment
Water deeply every 7 to 10 days through the first 2 summers (less for xeric pines in heavy clay, they're prone to root rot). Winter water 1 to 2×/month October to March when soil is dry and unfrozen, evergreens transpire year-round. Year 3: taper to twice per month in summer; only during extreme drought thereafter.
