(9NEWS) — We’ve seen many images of the stunning fall colors coming out of the high country and other places in Colorado. Here in Denver, the transition to fall foliage has come around more slowly. But it is coming, and ash trees in City Park, Washington Park and even Wallace Park are leading the way.
(DENVER POST) — Autumn foliage may be a sign of summer’s end, but Denver Parks & Recreation is using the explosion of color as a way to motivate people to care for the long-term health of their trees — especially their ash trees.
Denver’s ash trees provide a colorful contrast to the subdued hues of the surrounding species, with white ash leaves turning a reddish-purple in the fall. Denver’s soil pH does not typically support trees with leaves that turn that color, which is why certain developers and city planners chose to plant large numbers of soil-tolerant ash in areas like Lowry, City Park and Wallace Park. And now those trees are being threatened by emerald ash borer.
