The Garden Bug: Wild Violets
By Brenda Weaver
If you choose to propagate wild violet plants, divide an established “clump” in spring or fall by gently separating the rooted stems from each other within the group, then replant them separately. Also, their seeds can be collected and sown in the fall, if you desire spring blooms. Other than watering following planting, and occasional watering throughout the growing season, wild violets require very little care. Their foliage is occasionally affected by spider mites in dry weather.
