What's Happening in Horticulture? October 2025 |
Greetings gardeners,
As the season winds down, October is a good time to tackle yard and garden cleanup—with pollinators in mind. Many beneficial insects rely on dead stems, leaf litter, and brush piles to take shelter during winter. Traditional landscaping practices rarely leave enough resources for these important creatures to survive. Try something new this fall and incorporate natural habitat features into your winter landscape, rather than clear everything out. Read on for practical tips to guide your fall gardening projects.
