Fertilization: Fertilize Dianthus plants with a balanced fertilizer every 4-6 weeks during the growing season.
Soil: Dianthus plants prefer well-draining soil that is slightly alkaline. Amend the soil with compost or sand if necessary to improve drainage.
Sunlight: Dianthus plants need full sun to thrive. They should be planted in an area that receives at least 6 hours of direct sunlight per day.

Common Pests & Diseases
Dianthus plants are relatively resistant to pests and diseases, but they can still be affected by a few common problems:
- Aphids: These small, soft-bodied insects can suck the sap from Dianthus leaves and flowers. Treat with insecticidal soap or neem oil.
- Spider mites: These tiny pests can cause yellowing and stippling on Dianthus leaves. Treat with a miticide.
- Fungal diseases: Dianthus plants can be susceptible to root rot, powdery mildew, and other fungal diseases. Water the plants carefully and avoid overhead watering to prevent these problems.
