Summer-Planted Cottonwood in Wyoming: Managing Transplant Stress

Why Timing Matters

Planting a 10-foot cottonwood in summer (Cheyenne, WY) is high-risk. Deciduous trees establish best in spring (after frost, before leaf-out) or fall (after color change, before freeze). Summer heat amplifies transplant shock.

Critical Care Protocol

1. Hole preparation: Twice the root ball width, same depth, backfilled with native topsoil.
2. Mulch: 3 inches organic, not touching trunk.
3. Water: 1 inch every 3 days (pan test). Daily watering in dry climates may be needed initially.

What to Expect

Yellowing leaves are a stress response. If the root ball was intact and watering consistent, the tree should recover and push new growth next spring. Do not fertilize the first year.
