Water Dianthus pungens thoroughly when the top 2-3 cm of soil feels dry to the touch. Avoid waterlogging, as this can lead to root rot.

Reduce watering frequency during winter months when the plant is dormant, allowing the soil to dry out more between waterings.

Deadhead spent flowers regularly to encourage continuous blooming and maintain a tidy appearance. Lightly prune back after the main flowering period to shape the plant and prevent it from becoming leggy.

Remove any dead or damaged foliage as needed.

Dianthus pungens can be propagated by stem cuttings taken in late spring or early summer.

Select healthy shoots, cut them about 7-10 cm long, remove lower leaves, and insert them into a moist, well-draining rooting medium. Rooting typically occurs within 3-4 weeks.

Repot Dianthus pungens every 2-3 years or when the plant becomes root-bound. Choose a pot that is only slightly larger than the current one.

Use a well-draining potting mix, ideally one formulated for Mediterranean plants or with added grit.
