Water moderately when the top 2-3 cm of soil feels dry. Gaillardia arizonica prefers well-draining soil and is drought-tolerant once established. Avoid overwatering, which can lead to root rot.

Water deeply but infrequently, allowing the soil to dry out between waterings.

Deadhead spent flowers regularly to encourage continuous blooming and maintain a tidy appearance. Cut back stems in late fall or early spring to remove dead or weak growth and to shape the plant.

This promotes vigorous new growth and improved flowering in the following season.

Propagate by seed sown in spring, or by division of established clumps in early spring or fall. Seeds may require stratification. Cuttings can also be taken from softwood in late spring or semi-hardwood in mid-summer.

Ensure good air circulation for cuttings.

Repot young plants every 1-2 years in spring, or when they become root-bound. Choose a well-draining potting mix.

Mature plants are often best left in situ or repotted infrequently as division is a more common method of rejuvenation. Avoid overly large pots.
