What's New - Spring/Summer 2023

Important Update - Emerald Ash Borer is Here

Emerald ash borer has been positively identified in Carbondale. This exotic pest has killed over 100 million ash trees in the United States and was first discovered in the Front Range of Colorado in 2013. Since that time, Emerald ash borer has been found in numerous northern Front Range communities. While the Rocky Mountains have provided a natural barrier to this insect reaching the Roaring Fork and Vail Valleys, we knew it was likely to arrive here with human assistance – either via firewood or in nursery stock. Unfortunately, that day has arrived.

Emerald ash borer attacks both green and white ash varieties. The larva tunnel the cambium layer of host trees, reducing the tree’s ability to move water and nutrients, resulting in death. High value trees can be treated with systemic insecticides to protect them. If you have ash trees on your property that you want to protect, please contact us for an estimate.

For the Birds

Earth-Wise is a proud supporter of Colorado Rocky Mountain School’s osprey nesting project.  In recent years, Earth-Wise has donated time in the spring to remove unsafe material (entanglement hazards) from the birds’ nest.  Check out the osprey family on the CRMS live camera:

The Woman, the Myth, the Legend

A special shout out to our bookkeeper, Cheryl McGrath, who after 19 years with Earth-Wise (before Ed & Priska even owned the company!), is stepping into retirement.  We are grateful for her time with us and wish her the best in her new adventure!  In June, we welcome Sarah Carpenter, our new bookkeeper, into the Earth-Wise family.
