Dianthus plants prefer well-draining soil with a slightly alkaline pH (around 7.0).
Dianthus plants require regular watering, especially during dry periods. However, overwatering can lead to root rot, so it is important to allow the soil to dry out slightly between waterings.
Dianthus plants prefer full sun, but can tolerate some light shade.
Dianthus plants are hardy and can tolerate cold temperatures, but may not survive in extremely hot or humid conditions.
Dianthus plants can be propagated by seed or by taking stem cuttings. Seeds should be planted in early spring, while stem cuttings can be taken in early summer.
Dianthus plants are susceptible to fungal diseases, such as powdery mildew and leaf spot. Regularly removing dead or infected plant material can help prevent the spread of disease. Pests, such as aphids and thrips, can also be a problem, and can be controlled with insecticidal soap or neem oil.
