News Release

2018 Four Seasons Gardening Winter Webinar Series

University of Illinois Extension’s Four Seasons Gardening program focuses on environmental stewardship, home gardening, and backyard food production. The webinars are being offered at the U of I Extension offices in Waterloo and Collinsville.

On February 27 at 1:30 p.m. The Green Pathway to Invasion: Ornamental Invasive Plants will be presented. May of our worst invasive plants actually started as ornamental plants. Join Chris Evans, University of Illinois Extension Forestry and Research Specialist, as he explores why some plants end up becoming invasive, discusses some invaders that are still in the ornamental trade, and gives recommendations on how landowners can influence the surrounding natural landscapes through their planning decisions.

The webinars are free and are presented by a live instructor with participation across the state. In Waterloo you may attend at the Monroe County Annex Building, 901 Illinois Avenue and in Collinsville at 1 Regency Plaza Drive, Suite 200. Each session will last about one hour and handouts will be provided.

On March 13, 1:30 p.m. the topic will be Tree Care in Urban Soils, and on March 27, 1:30 p.m. Keep on Growing: Tips for Extending the Gardening Season.
