Tomato ‘Black Krim’ Seeds

Heirloom Beefsteak Variety

Tomato ‘Black Krim’ is a highly sought-after heirloom beefsteak variety originating from the Crimea, prized for its distinctive dark colouring and rich, complex flavour. Producing large, flattened fruits with deep red-purple tones and characteristic dark green to brown shoulders, Black Krim stands out both in the garden and on the plate.

Fruits typically weigh between 8–14 oz (225–400 g) and offer a unique flavour profile — rich, smoky, slightly sweet with a natural salty tang. This makes Black Krim an exceptional choice for slicing, salads, and fresh eating.

As an indeterminate (cordon) variety, plants grow tall and continue producing fruit throughout the season. Vigorous and productive, Black Krim performs well in both hot summers and varied growing conditions, though consistent watering is important to reduce fruit cracking.

How to Grow Tomato ‘Black Krim’

Sow seeds indoors from February to April in fine seed compost. Cover lightly (approx. 3 mm) and maintain a temperature of 18–22°C for germination.

Once seedlings develop, pot on into larger containers and grow in bright, frost-free conditions. Harden off plants before planting outdoors after all risk of frost has passed.

Plant in a sunny, sheltered position in a greenhouse or outdoors in warm conditions. Provide strong support such as canes or stakes, as plants can reach 4–6 ft (120–180 cm) in height.

Remove side shoots regularly to maintain a cordon habit. Water consistently and feed weekly once flowers appear to support fruit development.

Care Tips

Maintain even watering to reduce the risk of fruit cracking

Provide good airflow to support healthy growth

Harvest fruits when fully coloured for the best flavour
