Cuore di Bue Tomato problems — and how to fix them
Cuore di Bue Tomato (Solanum lycopersicum 'Cuore di Bue') 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
Large oxheart fruit frequently develops leathery dark bases from uneven watering; consistent moisture and mulch are the remedy, not added calcium.
Catfacing and ribbing
Big beefsteaks can deform if pollination occurs in cool weather; warmth at flowering improves fruit shape.
Fruit cracking
Heavy fruit splits after rain following drought; even watering and mulching steady soil moisture.
Late blight
Spreading brown lesions in warm, wet weather; improve airflow, water at the base and remove affected tissue quickly.
