Water Calea anomala moderately when the top 2-3 cm of soil feels dry. Avoid overwatering, as this can lead to root rot. Ensure the pot has good drainage. Reduce watering frequency during cooler months when growth slows.

Prune Calea anomala to maintain its shape and encourage bushier growth. Lightly trim back leggy stems in spring or after flowering. Remove any dead or damaged branches throughout the year. Avoid heavy pruning.

Propagate Calea anomala from stem cuttings taken in spring or early summer. Dip cuttings in rooting hormone and plant them in a moist, well-draining potting mix.

Keep the cuttings in a warm, humid environment until roots form.

Repot Calea anomala every 2-3 years, or when it becomes root-bound. Choose a pot one size larger than the current one and use a well-draining potting mix. Repot in spring before new growth begins.
