Pinion pine, ponderosa pine, Rocky Mountain juniper, Douglas-fir, white fir and blue spruce are good choices to achieve the look and feel of the great outdoors right in your backyard. Other trees used occasionally to achieve a natural look include lodgepole, limber and bristlecone pine and Englemann spruce. Don't assume, however, that all these native species are drought-tolerant. Once established, pinion, ponderosa pine and Rocky Mountain juniper are, but Douglas-fir, white fir, and blue spruce thrive on additional moisture. Consider soil conditions, however, before watering.
All evergreens share some common needs.
Lack of snow cover and warm days alternating with very cold weather creates problems that winter watering can help overcome. Do not use black plastic as a mulch, as it inhibits air and water from entering the soil. Native evergreens aren't heavy feeders. Too much fertilizer can lead to pest problems. Don't use a lawn-type fertilizer that contains weed killer.
