Anatomy of a Tree: The Trunk
Just as knowing your body and how to take care of it, learning the parts of a tree and the roles they play can help you keep your trees healthy and in good shape. Today, we’ll take a look at the tree’s most fundamental structure, it’s trunk and branches.
Every Day is Earth Day
Earth Day was April 22 and a lot of people no doubt made resolutions, just like they did for the New Year. And just like New Year’s resolutions, many will be forgotten within a few weeks.
Trees of Colorado: Ginkgo Biloba (Maidenhair Tree)
If you want a beautiful, exotic shade tree that’s a living fossil too, you might want to look at the gingko. Unique among existing trees, the gingko is a species apart. It has no living relatives, all others having disappeared over its 270-million-year history.
When is the Best Time to Prune Your Trees?
Experts agree that the best time to prune most landscape is from mid-February until early March. The trees are still dormant but are nearing the time that new growth will emerge. Late winter pruning allows enough time for the wounds to heal without exposing them to a full winter of stress. Plus, it encourages new growth to occur in places you want it.
The Bristlecone Pine
Bristlecone pines are tough customers. They grow where nothing else will and last for centuries. In fact, a Great Basin bristlecone pine in California’s White Mountains has been calculated as being 5,067 years old, making it the oldest known individual tree on earth. Clonal colonies of plants and microorganisms can last for 10,000 or more years—the Pando colony of quaking aspens in Utah, for example—but when it comes to individual organisms, the bristlecone is champ.
Fall Home and Landscape Checklist
While the holiday season tends to focus on indoor activities, there are several things to do outdoors, too. From making your home attractive and welcoming to visitors and passers-by to getting a head start on spring, here are some things to consider.
The Colorado Blue Spruce
The mountains of Colorado kept an arboreal secret for centuries until botanists identified a variety of blue spruce unique to the Rocky Mountains in 1862. Today, the Colorado blue spruce is one of the most popular ornamental and landscape conifer trees in North America. It’s also the official state tree of Colorado.
The English Oak
From the mythical forests of Robin Hood to the parks of Denver, the majestic English oak has graced temperate climate landscapes for centuries. And centuries is a key word when talking about English oaks—they live for hundreds of years, especially when well cared for. The oldest living specimens are in Bulgaria and Lithuania, estimated to be around 1,500 years old.
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.
