Watering, pruning, propagation, and repotting details from plant data
Alpine waterleaf thrives in consistently moist soil, mimicking its native alpine bog and streambank habitats. Water regularly to keep the soil damp but not waterlogged.
Reduce watering slightly during winter dormancy, but never allow the soil to dry out completely. Ensure good drainage to prevent root rot.
Pruning is generally not required for alpine waterleaf, as it maintains a neat, clumping habit. Remove any dead or damaged foliage at the base of the plant as needed.
Deadheading spent flowers can tidy the appearance, but is not essential for plant health.
Alpine waterleaf can be propagated by division of established clumps in early spring or fall. Alternatively, fresh seeds can be sown in autumn or after a period of cold stratification.
Division is the most reliable method for home gardeners.
Repotting is infrequent, as Hydrophyllum alpestre prefers to be undisturbed. If grown in a container, repot every 2-3 years in spring or fall into a slightly larger pot with fresh, well-draining potting mix.
Ensure the new pot has adequate drainage holes.
