Early spring is the best time to plant trees in Colorado. Fall is the next best time to plant. Gardeners should complete all planting by mid-October.
The tree's growth cycle should be considered before planting. A tree should not be planted when it is producing new buds and has soft roots.
Gardeners should wait for a calm, cloudy and humid day to plant a tree. If they are planting a bare root tree, they should soak the roots in a bucket of water overnight before planting. Before planting, trees should be stored in a shady spot that is protected from wind.
