It may feel counterintuitive, but winter is actually one of the healthiest seasons for tree trimming. When trees are dormant—and not busy pushing new growth or showing off their leaves—it’s the perfect time to give them a little shape-up.

Once snow enters the forecast, emergency pruning and storm-damage calls spike—fast. Scheduling now ensures your trees get the attention they need before the weight of winter puts them to the test.

DLC is now offering Holiday Light Installations this winter, and we’re kicking things off early with a little Christmas in July cheer.

Most people know us for pruning, removals, and preventative care—but there’s another side of our work that’s just as important: We plant trees. And lots of them.

Colorado summers can be tough on trees. This quick guide shares essential watering tips, pest-watch reminders, and simple ways to keep your trees healthy and stress-free all season long.

As spring arrives in the Denver Metro area, trees, shrubs, and plants awaken from dormancy, requiring proper spring maintenance to ensure your landscape thrives throughout the growing season while protecting against pests, diseases, and environmental stress.

The Emerald Ash Borer (EAB) has killed millions of ash trees, costing billions. Denver could face up to $1B in losses if all its 210,000 ash trees die, with removal costs, lost property value, and replacement expenses. Prevention and treatment are key.

Norway Maples, a popular new tree along South High Street in Denver, grow 60-90 feet tall and have tough bark and bright yellow fall foliage. They're less susceptible to storm damage and are recommended by the Colorado State Extension Service.

The Hippopotamus is the closest relative to the whale, illustrating how species adapt to environments. Similarly, deciduous trees evolved to drop leaves to conserve water and food in dry climates, helping them thrive globally. Denver’s urban canopy has increased humidity.

The Tetrastichus planipennisi wasp, released in Boulder to combat emerald ash borer (EAB), targets EAB larvae by laying eggs that feed on them. With up to 100 eggs per host, it helps slow EAB spread. Other wasps may be introduced this summer for further control.

Each year brings more warm, dry days into fall and winter, and this year is no different. Though trees slow down in October, they’re still alive. Warm, dry days can wake them, much like poking a hibernating bear. Keep them hydrated and healthy.

The biggest threat to Denver trees isn’t insects or disease—it’s snow on leafed-out trees. Heavy snow in spring or fall can break branches or topple trees, especially those with weak growth or improper pruning. Young trees are especially vulnerable.
