Striped Roman Tomato problems — and how to fix them

Striped Roman Tomato (Solanum lycopersicum 'Striped Roman') 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.

Blossom-end rot

Elongated paste fruit commonly shows leathery dark bases when watering is erratic; keep moisture even and mulch rather than adding calcium.

Late ripening

Dense-fleshed paste fruit matures slowly; start early and prune to a few strong stems in short-season areas.

Late blight

Brown lesions on leaves, stems and fruit in warm wet spells; improve airflow, avoid wetting foliage and remove infected parts.

Hornworm damage

Large caterpillars strip foliage and bore fruit; hand-pick or treat with Bacillus thuringiensis, checking stems at dusk.
