Jeffco Plant Lab Services and Costs

We serve everyone who has bug, landscape, or garden questions!

We specialize in plants, insects/arachnids, and horticultural problems in Colorado and the Rocky Mountain Region. We receive questions from home gardeners and plant enthusiasts, as well as professionals including arborists, nurseries, garden centers, and greenhouse producers. We also serve landscape professionals and turf specialists who maintain the grounds for HOAs, golf courses, private lawns, and sod growers, and pest control companies. If you have a plant, insect, tree, or lawn problem, we are your local resource to find solutions for healthier landscapes, gardens, and plants.

Phone and email consultations are offered free of charge. No charge to investigate or identify beetles sent out for Emerald Ash Borer confirmation.

Keeping ahead of COVID-19

This rapidly evolving coronavirus (COVID-19) has imposed an unsettling, fluid situation upon our community and its businesses. While the team here still aims to maintain a “business as usual” approach, we are making a number of significant changes to our operations to account for a situation that is far from normal.
