Armstrong Garden Centers continues to host free weekend gardening classes this summer at every store location. Each class is instructed by certified nursery professionals who offer timely gardening advice and hands-on demonstrations. On August 9, at “Attracting Pollinators,” learn what to plant to create the best habitat for pollinators, which will thrive and help veggies, shrubs, and flowers be their best. On August 23, at “Small Space Gardening,” learn how to make the most of any outdoor space with unique small space ideas, with planters, patios, and entranceway groupings. No advance registration or RSVP is required to attend. Classes are open to gardeners of all levels. (www.armstronggarden.com)
