Sweet Violets prefer consistently moist soil, especially during dry periods and active growth. Water deeply when the top few centimeters of soil feel dry to the touch, but avoid waterlogging, which can lead to root rot. Reduce watering frequency in cooler months or during summer dormancy.

Pruning for Sweet Violets is quite straightforward and minimal. Focus on deadheading spent flowers regularly to encourage continuous blooming and prevent unwanted self-seeding. Remove any discolored, damaged, or diseased leaves to maintain plant health and aesthetic appeal. A general tidy-up of older foliage in late autumn or early winter can also be beneficial for overall vigor.

Sweet Violets are easily propagated by dividing their stolons (runners) in spring or autumn. Simply dig up a clump, separate the rooted plantlets from the main plant, and replant them in new locations. They also readily self-seed, and seeds can be collected and sown.

Repot container-grown Sweet Violets every 1-2 years in spring, or when they become root-bound. Choose a pot only slightly larger than the previous one and use fresh, well-draining potting mix. This helps refresh the soil and provides space for new growth.
