Water
Water consistently, especially during dry periods, to keep the soil evenly moist. Avoid waterlogging, as this can lead to root rot.
Allow the top inch of soil to dry out slightly between waterings for optimal growth and flowering.

Watering, pruning, propagation, and repotting details from plant data
Water consistently, especially during dry periods, to keep the soil evenly moist. Avoid waterlogging, as this can lead to root rot.
Allow the top inch of soil to dry out slightly between waterings for optimal growth and flowering.
Remove spent flower stalks to encourage reblooming and maintain a tidy appearance. In late winter or early spring, trim back any dead or damaged foliage to promote new growth. This also helps prevent fungal diseases.
Divide established clumps in early spring or fall. Carefully separate the root ball into smaller sections, each with healthy roots and shoots.
Replant immediately into well-draining soil and water thoroughly to help them establish.
Repot container-grown Heuchera every 2-3 years, or when the plant becomes root-bound. Choose a pot only slightly larger than the current one.
Refresh the potting mix with a well-draining blend, incorporating compost for nutrients.
