Troubleshooting
Mignonette Alpine Strawberry problems — and how to fix them
Mignonette Alpine Strawberry (Fragaria vesca 'Mignonette') 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.
Drought stalling production
Clumps stop fruiting and flag if the shallow root zone dries, a frequent issue in pots. Keep moisture even and mulch to sustain all-season cropping.
Birds and slugs
The small fragrant berries attract birds and slugs damage low-hanging fruit. Net plants, set slug barriers or traps, and mulch with straw to keep berries clean.
Botrytis grey mould on fruit
Ripe berries rot with grey fuzz in damp, congested plantings. Space plants for airflow, remove mouldy fruit and water at the base rather than overhead.
Loss of vigour over time
Older clumps crop less heavily after a few seasons. Refresh plantings by dividing strong crowns or sowing fresh seed every two to three years.
