Troubleshooting
Seascape Strawberry problems — and how to fix them
Seascape Strawberry (Fragaria × ananassa 'Seascape') 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.
Grey mould (botrytis)
Its long, overlapping flushes give botrytis many chances. Keep ripe fruit picked, ensure airflow, water at the base, and remove any rotting berries at once.
Heat-induced flower drop
Day-neutral flowering stalls in prolonged heat above roughly 30°C. Provide afternoon shade and keep roots cool and moist with mulch to keep flushes coming.
Aphids and tarnished plant bug
Sap feeders distort flowers and cause catfaced, misshapen berries. Encourage predators, rinse off aphids, and keep plants vigorous with even watering.
Vine weevil in containers
Root-eating larvae cause wilting in pots and baskets. Use nematode treatments and renew compost regularly, since this cultivar is so often container-grown.
