Maintain consistently moist soil, especially during the growing season. Avoid waterlogging, which can lead to root rot. Water at the base of the plant to prevent fungal diseases on the foliage.

Reduce watering slightly in late fall and winter when growth slows.

Remove dead, damaged, or diseased leaves and flower stalks as needed. Cut back to the ground in late fall or early spring to tidy the plant and prevent overwintering pests. This also encourages fresh, healthy new growth.

Hosta hypoleuca is primarily propagated by division. In early spring or fall, carefully dig up the plant and divide the root ball into sections, ensuring each section has at least one growth bud.

Replant the divisions immediately.

Hosta hypoleuca generally does not require frequent repotting if grown in the ground. If grown in a container, repot every 2-3 years or when the plant becomes root-bound.

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