Packera millelobata prefers consistently moist soil, especially during its active growth period. Water thoroughly when the top 2-3 cm of soil feel dry. Avoid waterlogged conditions, as this can lead to root rot.

Reduce watering slightly during dormancy.

Deadhead spent flower stalks to encourage more blooms and maintain a tidy appearance. Cut back the foliage to the ground in late fall or early spring to make way for new growth.

Remove any dead or damaged leaves throughout the growing season.

Packera millelobata can be propagated by division of established clumps in early spring or fall. Sow seeds in fall or early spring. Cuttings can also be taken from basal shoots in spring.

Repot Uinta Ragwort every 2-3 years, or when the plant becomes root-bound. This is best done in early spring before new growth emerges.

Choose a pot only slightly larger than the current one, and use well-draining potting mix.
