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.

Mature size: 1.5-2.1 m tall as a cordon; sprawls wider if left unsupported.

Indoor size vs how big it gets in the wild

Cuore di Bue Tomato reaches its full size within one growing season — there is no "long-term" size, just how big it gets before you harvest or it dies back. Indoors and in a pot, expect 1.5-2.1 m tall as a cordon. In the ground with no restriction it is a completely different plant — sprawls wider if left unsupported. — which is why the pot, the light and the pruning matter so much for the size you actually end up with.

It sizes up fast and once, racing from seedling to full size in a single season; after cropping it is finished, so size is a within-season question.

Growth rate and years to mature

Cuore di Bue Tomato is a fast grower. Realistically, expect a single growing season — it reaches full size in one year, then is done. Its feeding profile backs this up: balanced feed at planting, then a high-potassium tomato feed weekly once fruit sets. avoid heavy nitrogen, which delays ripening of the large fruit.

When cuore di bue tomato outgrows the room (or the pot)
