Site factors to consider
- Critical: Cold HardinessThe average low suits it fine; our real cold risk is the swings, late frosts, and intense winter sun, so wrap young trunks and give it shelter.
- Watch: TransplantsIt resents being moved, so start with smaller stock, plant in spring, and get the spot right the first time.
Common problems on the Front Range
- Aphids and honeydew
- Verticillium wilt on some species
- Leaf scorch in hot, dry, windy sites
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 7–10 days through the first 2 summers. Winter water 1–2×/month October–March when soil is dry and unfrozen, winter desiccation is a top killer of newly-planted trees. Year 3: taper to 2×/month in summer, then rely on natural precipitation.
