Bulbous Buttercup problems — and how to fix them
Bulbous Buttercup (Ranunculus bulbosus) 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.
Corm rot in wet soils
The swollen stem base is highly prone to rotting in waterlogged or heavy clay soils; always plant in sharply drained ground and raise beds on heavy soils using grit incorporation.
Competition from vigorous grasses
In grassland settings the bulbous buttercup is easily suppressed by coarse, rank grass growth; manage surrounding sward height and avoid fertilising to keep the plant's low-fertility niche open.
