Lesser Water Plantain problems — and how to fix them
Lesser Water Plantain (Baldellia ranunculoides) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Displacement by vigorous aquatic weeds
This delicate species can be crowded out by more aggressive marginals such as Typha or Glyceria. Keep the planting area clear of competing species by manual removal each spring.
Failure to flower without sufficient sun
In shaded positions, plants produce leaves but few flowers. Move containers to a sunnier pond shelf or clear overhanging vegetation to improve light levels.
Loss in nutrient-rich pond water
In heavily fertilised or high-nutrient garden ponds, this species declines rapidly. It is best suited to wildlife ponds with natural, low-input management.
