Water moderately, allowing the soil to dry out slightly between waterings. Avoid waterlogged conditions, which can lead to root rot. Ensure good drainage, especially in containers.

Reduce watering during dormant periods to prevent overhydration.

Prune lightly after flowering to shape the plant and remove spent blooms. This encourages bushier growth and can prevent self-seeding if desired.

Remove any dead or damaged stems at any time of year to maintain plant health and appearance.

Propagation is typically done by sowing seeds in autumn or early spring. Seeds may require stratification for improved germination. Direct sowing into the garden is often successful in suitable conditions.

Cuttings are generally not a reliable method.

Repotting is rarely necessary as Odontites cebennensis is a short-lived perennial or annual that prefers to grow in its natural, often lean, habitat. If grown in a container and it becomes root-bound, repot in spring into a slightly larger pot with well-draining soil.
