A PRECAUTIONARY TREE TALE
Former United States Vice President Al Gore first sounded the alarm about global warming in 1976. Three decades later, some dissenters say it isn’t so. But now there’s proof that even the trees know it’s real.
A 2018 Guide for Cutting Your Own Christmas Tree in Colorado
Did you know that by cutting your own Christmas tree (or Hanukah bush or Festivus pole) you‘re actually helping with forest management? Thinning forests lets sunlight reach deeper into the canopy, encouraging new, more diverse growth and reducing competition for nutrients.
Winter Watering Keeps Trees Healthy and Happy
Trees are living organisms that need nutrition all year round. Even in the dead of winter your trees and shrubs are busy underground, growing and storing food and energy for springtime emergence.
The Science of Fall Color
If you’ve ever wondered why some leaves turn red while others turn orange, yellow, or brown—or stay green all year long—the answer hides just below the surface. The leaves, you see, aren’t naturally green at all.
Put Your Fall Leaves to Good Use
Time was the smell of leaves burning was a sure sign of fall. While it was bad for the environment—and the occasional house or garage—the smoky aroma ranked right up with pumpkin pie and warm cider as a favorite seasonal scent until the practice was largely banned.
Today that aroma has been replaced by the ear-splitting sound of leaf blowers gathering leaves in a pile to be bagged and left out with the trash.

As long as the soil is workable, trees can be planted, and in most lower-altitude Colorado locations that means planting time extends well into late fall and even early winter before subsoil freezing becomes an issue.
Trees of Colorado: The Mountain Mahogany
If you’re looking for a small tree to accent your low-maintenance landscape, the mountain mahogany is an excellent choice. Native to Colorado’s rocky slopes, when mature, it has an attractive, twisted appearance that some liken to the African savanna.
