About Cuore di Bue Tomato
Solanum lycopersicum 'Cuore di Bue' · also called Cuore di Bue tomato, ox heart tomato · edible
Cuore di Bue is a classic Italian oxheart beefsteak with large, ribbed, heart-shaped red fruit, dense low-seed flesh and rich flavour. The indeterminate vines are productive but need firm support for the heavy fruit, plus full sun and a long warm season. Its foliage and unripe fruit are toxic to pets.
Preferred mix: Deep, fertile, free-draining loam
Watch for — Fruit cracking: Heavy fruit splits after rain following drought; even watering and mulching steady soil moisture.
Why cuore di bue tomato needs this mix
Cuore di Bue Tomato is a hungry, thirsty crop — it wants a rich, moisture-retentive but free-draining loam, well fed and never baked dry.
- Cuore di Bue Tomato grows fast and has a big crop to fill, so it draws heavily on both nutrients and water — a lean mix simply cannot keep up.
- Plenty of organic matter holds moisture evenly, which prevents the stress problems (bolting, bitterness, blossom-end rot) that come from a drying-then-flooding cycle.
- It still needs structure: rich does not mean airless, so grit, perlite or leaf mould keeps roots oxygenated.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons cuore di bue tomato struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- A poor, thin or sandy mix starves cuore di bue tomato — growth stalls, leaves pale, and yields collapse.
- A heavy, compacted, badly drained soil rots the roots and brings fungal problems despite all the feeding.
- Letting a rich mix dry to dust then drowning it causes the classic moisture-stress disorders this crop is prone to.
Under-feeding and inconsistent moisture. Cuore di Bue Tomato needs genuinely rich soil plus steady watering — most disappointing crops come down to one or both being short.
