Fast - growing trees for impatinent gardeners

摘要

Trees provide benefits almost too numerous to count, helping to moderate climate, improve air quality, conserve water, and shelter wildlife—to name just a few. They shield our homes from harsh winds and blazing sunlight, easing our heating and cooling costs. Trees can provide privacy, emphasize beautiful views or screen undesirable ones, and complement architecture. But trees also inspire us and tug at our heartstrings. We form emotional bonds to trees, and we mourn the decline and death of magnificent old specimens.
