When is the Best Time to Prune Your Trees?
Experts agree that the best time to prune most landscape is from mid-February until early March. The trees are still dormant but are nearing the time that new growth will emerge. Late winter pruning allows enough time for the wounds to heal without exposing them to a full winter of stress. Plus, it encourages new growth to occur in places you want it.

The US Department of Agriculture publishes a list of Plant Hardiness Zones to help gardeners determine which plants are likely to survive in a given geographical location. But these zones are based on average minimum winter temperatures and don’t take other factors like precipitation and soil condition into account. Most of Metro Denver falls in USDA Zones 4-6, but with the wide range of growing conditions facing Coloradans, knowing a climate zone may not be enough information for successful planting.
