Heuchera richardsonii prefers consistently moist soil but dislikes waterlogged conditions. Water deeply when the top inch of soil feels dry, especially during dry spells. Reduce watering in cooler months.

Avoid overhead watering to minimize the risk of fungal diseases.

Prune Heuchera richardsonii in late winter or early spring before new growth begins. Remove any dead, damaged, or diseased foliage from the previous year.

Deadheading spent flower stalks can encourage a tidier appearance and potentially more blooms. Shearing back can refresh the plant.

Heuchera richardsonii is easily propagated by division in early spring or fall. Carefully dig up the plant and gently separate clumps, ensuring each division has healthy roots and at least a few shoots.

Replant divisions immediately into prepared soil.

Repotting is generally not necessary for Heuchera richardsonii unless grown in containers or if the plant becomes severely overcrowded. If repotting, do so in early spring or fall.

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