With spring around the corner, you might be itching to plant and prune. Colorado State University Extension offers free monthly webinars to help cultivate your green thumb.  

Held at noon on the second Wednesday each month, the 2025 horticulture webinars each cover a different topic – from vegetables and soil to insects and native plants. Trees and lawns get some love too. 

Registration is required, and all webinars are recorded and posted afterward on the PlantTalk website.
