How can you take care of Vinca rosea?

To care for Vinca rosea (periwinkle), ensure it receives full sun to partial shade and well-draining soil. Water the plant moderately, allowing the soil to dry out between waterings to prevent root rot. Fertilize every few months with a balanced fertilizer during the growing season, and prune as needed to maintain shape and encourage bushier growth. Additionally, protect it from extreme cold and monitor for pests like aphids and spider mites.
