Greetings gardeners,

September is here, and with it come cooler nights, golden light, and full harvest baskets. While this is a time to savor the season’s bounty, it’s also a reminder to keep an eye out for changes in our landscapes. Recently, Japanese stiltgrass was detected in Wisconsin for the first time, an invasive plant that can crowd out forests, lawns, gardens, and other natural ecosystems. Staying aware of emerging threats helps us protect the places where we live, work, and play. Read on for timely tips and resources to make the most of your garden before fall.
