Growing Groceries Classes

Growing Croceries online classes are popular with gardeners of all ages & novice to intermediate abilities. If you want to grow edible crops at home or in your local p-patch, this educational series is something you will enjoy. Classes cover diverse topics and a cornucopia of foods you can cultivate in the maritime climate – from summer fruits, berries, and vegetables, to perennial herbs, cool season crops, winter greens, and tender spring veggies. Classes are held online via zoom on Wednesday evenings from 7pm to 8:30pm. But they fill up fast, so don’t delay. Check out our complete lineup of Growing Groceries classes.
