Black Cherry tomato seeds produce hardy, vigorous vines loaded with gorgeous purple to mahogany brown cherry tomatoes 2.5 cm (1″) round. Enjoy prolific yields all season long! Rich, juicy cherry tomatoes with wonderfully complex, sweet flavour and firm texture. The little fruits of this variety look exotic and taste irresistibly delicious. A great snacking tomato, excellent in bruschetta.
Black cherry tomato seeds are easy to grow, and plants are naturally disease resistant. Vines typically grow at least 150 cm (60″) and require caging or staking for support. For best results, allow these cheery tomatoes to ripen on the vine, and harvest regularly. Fruits are ripe when they turn olive/eggplant in colour and they pop readily off the stem with a roll of the fingers.
Tomatoes are easy to grow from seed sown indoors in warm conditions. Sow from late Feb is you have propagation equipment or late March to early April otherwise.
Sow in small pots or cells filled with seed compost, then either place in a propagator or cover each pot with a clear plastic bag and place on a bright windowsill. The young seedlings need to be kept at around 18°C (64°F). Transplant into 9cm (3½in) pots when two true leaves have formed. Plant out into a greenhouse or polytunnel in May and be ready to protect them from frost until June.
When the flowers of the first truss are beginning to open, transfer to 23cm (9in) pots or growing bags, or plant outside in a warm sunny spot, 45–60cm (18–24in) apart
Cordon (or indeterminate) tomatoes – tie the main stem to a tall, sturdy bamboo cane or wind it round a well-anchored but slack vertical string (coming down from an overhead support). Regularly remove sideshoots that sprout from between a leaf and the main stem. When plants reach the top of the support or have set seven fruit trusses indoors or four trusses outdoors, remove the growing point of the main stem at two leaves above the top truss.
Bush (or determinate) tomatoes – these, and trailing types for hanging baskets, don’t usually need support. You won’t need to remove sideshoots.
Water regularly to keep the soil/compost evenly moist. Fluctuating moisture levels can cause fruits to split. Feed every 10–14 days with a balanced liquid fertiliser, changing to a high potash feed once the first fruits start to form. Irregular watering, together with a lack of calcium in the soil, can cause a problem known as blossom end rot (see below), when the base of the fruit turns black and becomes sunken.
For cordon (indeterminate) tomatoes, there is evidence that removing some leaves above the ripening truss (which allows the fruit to be warmer during the day but cooler at night) can encourage slightly earlier ripening, without negatively affecting cropping. Removing leaves below the ripening truss doesn’t improve ripening but can help to reduce the spread of diseases such as tomato leaf mould and tomato blight, where these are a problem.
