Did you know that, according to the Colorado State Forest Service , late winter is the best time to prune trees in Denver? While there’s never really a bad time to remove dead branches, October through March is the best time of year to prune trees in Denver because trees are less susceptible to pests or disease during the winter season.  Because trees are still dormant in late winter wound closure will happen sooner if they’re pruned right before new growth emerges. Some of you may wonder how we’re able to determine which branches to prune or remove. Now that most of the leaves have fallen, how can our crew identify what will be able to grow them back come spring? Well, our exceptional crews have the training and experience to know what to look for to adequately prune trees in Denver. They’re able to use several determining factors to figure out how best to treat your tree. 3 ways to prune trees in Denver First, they begin by assessing the trunk and limbs for anything that m...

Let’s face it, in the fall, it seems natural to rake your leaves up before the snow sets in. But did you know that there are some great benefits in leaving your leaves unraked? For instance, using your unraked leaves as mulch around the base of your tree trunk can provide exceptional nutrients for your tree and lawn over the winter. They can also provide a warm cozy spot for bugs and animals to hibernate in so they’ll be ready to pollinate or add soil diversity come spring. However, there are some cases in which raking up your leaves is the best course of action To keep your trees healthy. For example, we’ve been seeing a lot of leaf spotting on our cottonwoods and aspens lately. This is usually caused by fungi or bacteria that can fly back up into open spores on tree limbs if not raked properly. Leaving the diseased leaves amuck allows for wind, rain, and even other pests to transport the disease anywhere. Spotted Leaves These leaf spot diseases come from a variety of fungal ho...

Here at ArborScape, we’ve observed a widespread case of fireblight in our apple and pear trees this season. It’s likely due to all the rain we received earlier this year, which is one of the many ways this disease can spread. Fireblight is an incredibly destructive bacterial disease that affects pomme fruit trees, such as crabapples, pear, and apple trees, as well as quince and firethorns. So if you have any of these trees, you’ll definitely want to be on the lookout for the following symptoms . Symptoms of Fireblight Fireblight can cause damage to just about every part of the host tree. Symptoms to look for can include damage in the form of a canker on the tree’s trunk or limbs or even leave behind a scorched-looking effect on branches and leaves that can even look wet.  But the easiest telltale sign is that the tips of the branches start to curl in, almost forming what we call a “shepherd’s crook”. If you’ve noticed any of these issues with your trees, don’t hesitate to get...

Have you ever wondered how trees stay alive during our torrid winters? While we’re able to bundle up against the cold weather, trees are left vulnerable outside against the harsh elements. So how do they stay protected enough to bloom again in the spring? This is where plant hardiness comes into play. But what exactly is plant hardiness? While a plant’s overall health is usually the best indicator to see if and how it survives winter, plant hardiness is more of a descriptor of a plant’s ability to survive adverse growing conditions, such as the dry, frigid winters we get here in Colorado. We’ve mentioned before why some leaves change color in autumn, and how chlorophyll production slowly stops as part of the tree’s natural cycle into dormancy. But that’s only the start of how a tree prepares itself for winter. This is where a plant’s hardiness comes into play. During autumn, a tree can sense the dwindling temperatures and shorter days so it starts to store its energy in the root sy...
