Troubleshooting
Upright Hedge Parsley problems — and how to fix them
Upright Hedge Parsley (Torilis japonica) 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.
Invasive self-seeding
Plants shed abundant hooked seeds that cling to fur and clothing and germinate freely; deadhead as flowers fade and remove seedlings promptly to prevent naturalisation in borders or wild areas.
Slug and snail damage
Young seedlings and basal foliage are vulnerable to slug grazing, especially in damp, shaded conditions; use copper barriers, slug pellets (ferric phosphate), or encourage ground beetles.
