Ensure proper air circulation around the plants to reduce the risk of fungal diseases. Avoid overhead watering, as wet foliage can contribute to the development of diseases.

Provide support for taller dianthus varieties to prevent them from flopping over, especially during heavy rainfall or strong winds. Stake the plants or use other support structures as needed.
