Water consistently when the top 2-3 cm of soil feels dry to the touch. Avoid overwatering, as this can lead to root rot. In hotter weather, more frequent watering may be necessary.

Reduce watering significantly during winter dormancy.

Pruning is generally not required for Cerinthe minor. Remove any dead or damaged foliage as needed. Pinching back young plants can encourage bushier growth. Deadheading spent flowers can prevent self-seeding if desired.

Cerinthe minor is easily propagated by seeds sown directly outdoors in autumn or early spring. Seeds can also be started indoors a few weeks before the last frost. It may also self-seed readily in the garden.

Repot young plants if they become root-bound, typically in spring. Use a well-draining potting mix. Mature plants generally do not require frequent repotting and prefer to be left undisturbed once established.
