Large-Leaved Waterleaf problems — and how to fix them
Large-Leaved Waterleaf (Hydrophyllum macrophyllum) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Slug and snail damage
The large, soft, hairy leaves are highly susceptible to slug and snail feeding, particularly in moist conditions; apply iron-phosphate pellets in early spring as growth emerges and after heavy rain throughout the season.
Drought stress and leaf scorch
Even brief dry spells cause leaf margins to scorch and the plant to wilt; in garden settings away from natural water sources, install drip irrigation or water deeply twice weekly during dry periods.
