Colorado blue spruce (Picea pungens) is adapted to Colorado’s climate, but no tree is immune to wind, saturated soil, drought, or structural defects. Root depth varies with soil, water, and site conditions; a spruce should not be assumed to have weak roots simply because roots are often concentrated near the soil surface.

Check for warning signs from a safe distance

Look for a new lean, exposed or lifted soil around the root area, a cracked trunk, or large dead branches. A sudden change after a storm may indicate a serious structural problem. Do not push or shake the trunk to test stability, and do not approach a tree that is leaning, uprooted, or near power lines.

Support long-term tree health

  • Water during prolonged dry periods when the soil is not frozen, adjusting for rainfall, soil type, and the tree’s age.
  • Spread a 2–4 inch layer of mulch over the root area where practical, keeping it several inches away from the trunk.
  • Avoid cutting roots or changing soil levels near the trunk; both can weaken or stress the tree.
  • When planting a new tree, choose a suitable site and stake only if needed. Use flexible ties that allow some trunk movement, check them regularly, and remove the stakes once the tree is established, generally within one or two growing seasons.

Watering and mulch support tree health, but they cannot anchor an unstable tree or guarantee protection in high winds. Do not stake a mature tree or install cables as a do-it-yourself fix.

After a windstorm

Stay clear of damaged trees, hanging limbs, and downed branches near utility lines. Contact the utility if a tree or branch is touching a power line. For other significant damage, have a qualified arborist assess the tree before attempting pruning or cleanup. Do not top a tree, cut large limbs from a ladder, or try to straighten a tree with a lifted root plate.

An arborist can evaluate the trunk, roots, and canopy and recommend whether the tree can be retained, needs pruning, or should be removed. Seek an assessment promptly if the tree has shifted or the soil around its base has lifted.
