Pruning: Properly pruning your dianthus plants can help increase the chance of repeat blooming and keep the plant tidy throughout the year. Flowers should be deadheaded once spent, especially on varietals known for repeat blooms. Throughout the year, remove any stems or leaves that look diseased or damaged. Come fall, prune back the plant until there are only 1 to 2 inches of stem remaining above the soil. The plant will go dormant for the season and regrow the following spring.

Diseases:
One of the biggest issues dianthus plants have is vascular wilt. Characterized by dull green stems that droop and eventually dry out, wilt is technically a fungus that can eventually kill an entire plant. Treatment is difficult as fungicides are not effective—therefore, it's important to rotate your plantings frequently and avoid planting in any soil that seems diseased. Additionally, dianthus plants may have issues with other common plant pests, such as spider mites and aphids. To treat, you can apply insecticidal soap or neem oil until all signs of an infestation are gone
