Troubleshooting
'Black Krim' Tomato problems — and how to fix them
'Black Krim' Tomato (Solanum lycopersicum 'Black Krim') 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.
Fruit cracking
Large, thin-skinned fruit splits at the shoulders after irregular watering or rain; water evenly, mulch, and harvest at first full colour.
Green-shoulder / uneven ripening
Shoulders can stay hard and pale in heat; provide gentle afternoon shade in extreme sun and avoid heavy nitrogen feeding.
Late blight
Dense foliage and damp weather invite spreading brown lesions; prune lower leaves, improve airflow, and water at the base.
Blossom-end rot
Beefsteaks are especially prone to a leathery base from inconsistent moisture; keep watering steady and mulch rather than dosing calcium.
