Origin and history of the tomato

The ‘Crimson Crush F1’ tomato is a hybrid bred by Simon Crawford and a Ph.D. student at Bangor University. It was the first offered on the market by Suttons. Unlike heirloom varieties, this hybrid’s seeds may not produce plants that are true to the parent. So, if you try to save your seeds, your new plants may not have the same fruit size or taste. It is also possible that the plant might not have the same level of blight resistance as the original.

Taste and characteristics of the ‘Crimson Crush’ tomato

While bred for its blight resistance rather than an intense flavour, the fruits of ‘Crimson Crush’ tomato are nevertheless sure to please. Its fruits are high-yielding and have a juicy and sweet, yet slightly acidic, full flavour.

The fruit is medium-sized and round, with some slight imperfections that add to its charm. They grow to be about 200 g each on average. This makes them perfect for slicing and as salad tomatoes.

‘Crimson Crush’ plants produce an abundant amount of fruit on long trusses. When grown indeterminately, the plants can easily reach heights of more than 120 cm tall. So, it is important to support these plants with stakes, trellises, or cages.

Growing and caring for ‘Crimson Crush’ tomatoes

‘Crimson Crush’ tomatoes are truly blight resistant. Other varieties will succumb to tomato blight (Phytophthora infestans), but ‘Crimson Crush’ is very blight-resistant and will even fight blight. The plant will keep growing and still produce abundant yields even after developing blight symptoms.

They are best grown outside in your garden in the full sun but can also be grown in containers or in a greenhouse. As ‘Crimson Crush’ is a cordon-type tomato, allow one or two main leader stems to grow and pinch out the side growth for best yields. Use wire to attach your plants to a trellis as they grow, or place tomato cages over them to provide the support they need.

Like most tomatoes, ‘Crimson Crush’ requires rich, well-draining soil. Whether supplementing your garden soil, or for use as a potting compost, our Plantura Organic Tomato & Vegetable Compost will provide an excellent source of peat-free organic matter and a healthy dose of nutrients that will sustain your plants as they grow. You can start your seeds indoors in March and plant outside once the risk of frost has passed.

Water your plants regularly as tomatoes do not like to dry out. Inconsistent watering can lead to developmental issues, like cracking of the fruit or blossom end rot. Throughout the growing season, your plants will need more nutrients as they consume what is available in the soil. When the first truss starts to develop fruit, use an organic slow-release fertiliser like our Plantura Tomato Food.

Harvest and uses

When your ‘Crimson Crush’ tomatoes are deep red and slightly soft to the touch, they are ripe and ready to harvest.

This can be anytime between July and October, depending on the weather and when you planted your plants. It is also possible to pick unripe fruit that has started to develop colour and allow it to ripen inside your house. Your ripe ‘Crimson Crush’ tomatoes are great in salads, delicious as sliced tomatoes on their own or in sandwiches. While they are a juicy tomato, they are meaty enough to make great sauces as well.
