The Pinyon Pine
When Spanish explorers reached the southern Rockies, they were greeted by a familiar sight. Large stands of short, bushy evergreen trees reminded them of the Stone Pines native to their homeland, so they called them by the same name—pino piñonero—a name they still go by today, albeit in a shortened form. And like its European cousin, the piñon, or pinyon, pine had been around for centuries, providing an important source of nutrition to ancient hunter-gatherer populations.
Plan Ahead for Spring Planting
Banish your winter blues by thinking ahead to spring. Avid gardeners know that winter is the best time to plan for the warm weather to come and get a head start on plentiful crops during Colorado’s short growing season. It’s also a great time to reassess your landscape plan.
The Chinkapin Oak
If you’re looking for a shade tree that a Denver city forester once described as being tough as a junkyard dog, take a look at the chinkapin oak. Sometimes spelled chinquapin, it’s a stately medium-size tree with a rounded canopy that’s native to the central midwestern US as far west as central Kansas and south into northeastern Mexico.
Trees for Sustainable Landscaping
Whether you’re going full xeriscape or just trying to optimize your landscape’s sustainability, don’t overlook your trees and shrubs.
Managing Storm Damaged Trees
This year’s winter has been a mild one with late March temperatures approaching the eighties. But Colorado residents know that Mother Nature isn’t ready to call quits to winter until mid-May, and she may be holding some snow and ice storms in reserve.
So You Want to Plant a Tree
Basic Steps, Prep and Where to Turn for Expert Advice
Adding a tree or two to your landscape is both an investment and a commitment. Taking some time to do your homework will pay off in long-term rewards, both aesthetic and financial.
Colorado Ecosystems 101
Its geographic diversity is one of Colorado’s main attractions. Our high plains, mountain valleys, alpine tundra, and high western plateaus offer a mind-boggling variety of roughly 60 different ecosystems. And with that variety comes a range of climates that dictate the plants and animals that will thrive in them.
Benefits of Rain Gardens
As urban areas are built up, the rain falling on them runs off rooftops and paved areas into storm sewers that carry it away. Instead of falling onto open ground, where it’s filtered by soil and plants, it typically flows through the sewers directly into a nearby river or stream, carrying pollutants such as oil and chemical products along with it.
When is the Right Time to Remove Your Tree?
By late springtime, your trees should be leafed out, growing, and healthy looking. If that’s not the case, it may be time to consider removing any that look like their best years may be behind them, pose safety risks, lack room to grow, or are an undesirable species or “volunteer” tree that’s messy or weak. Here are some things to look for, starting from the ground up.
Did You Know That the Rain That Falls on Your Property May Not Be Yours?
Just because rain lands on your property doesn’t necessarily mean you can collect and use it. In fact, it’s only been a little over a year that collecting water in rain barrels has been legal in Denver. And even that comes with a list of restrictions.
What We Can Learn from Tree Rings
You probably know that counting the concentric rings in a cross-section of a tree trunk can tell the tree’s age. But that’s just the beginning of the wealth of information contained in the rings. Scientists can examine and test the rings to uncover years, even centuries, worth of knowledge about climate, atmospheric changes, and local geography.
Why Do Trees Uproot?
If you’ve ever tried to remove a tree or clear a stump, you know that these plants can have extensive root systems that cling tenaciously to the soil around them. So why do we see so many stories of trees uprooted by storms? Here are some reasons.
