Keep soil consistently moist but not waterlogged, especially during warmer months. Water at the base of the plant to avoid wetting the foliage, which can lead to fungal issues.

Reduce watering in autumn as the plant enters dormancy, allowing the soil to dry slightly between waterings.

Remove any dead, damaged, or diseased leaves as soon as they appear to maintain plant health and appearance. After flowering, deadhead spent flower stalks to encourage more blooms and prevent seed formation.

Cut back all foliage to the ground in late autumn or early spring.

Propagate Hosta plantaginea by division in early spring or autumn. Dig up the clump and carefully separate it into smaller sections, ensuring each section has at least one growth bud and some roots.

Replant immediately at the same depth as the parent plant.

Repot container-grown Hosta plantaginea every 2-3 years, or when the plant becomes pot-bound. Choose a pot one size larger than the current one. Use a well-draining potting mix.

Spring is the ideal time to repot, just as new growth begins to emerge.
