History of the Black Krim Tomato

The Black Krim tomato comes to us from the Crimean Peninsula, which is why it’s also known as a “Black Crimea” tomato (or a Noire de Crimee). It’s thought that soldiers who returned home at the end of the Crimean War (1856) gathered up Black Krim tomato seeds that were then passed down through their families.

Black Krim tomatoes became known outside of Crimea when they were introduced to Seed Savers Exchange (SSE) in 1990 by Lars Olov Rosenstrom of Sweden. These were the first commercially available “black” tomatoes in the US.

Characteristics of the Black Krim Tomato

The Black Krim (Lycopersicon esculentum or Solanum lycopersicum ‘Black Krim’) is a beefsteak tomato that turns a dark maroon color with “green shoulders” — the area on the tomato right around the stem. The more sun exposure a Black Krim gets, the darker the color it turns. When grown in very hot and sunny climates, the color deepens to almost black — hence, the name.

Ripening Season

The Black Krim is a mid- to late-season indeterminate tomato, meaning its fruit will mature and ripen at different times, rather than all at once.  Black Krims start to ripen in August. Under ideal conditions, you’ll be able to harvest into September, at which time the nighttime temperatures will drop and bring tomato season to an end.

Tomato Qualities

The inside of a Black Krim contains reddish-green flesh with a moderate to low number of seeds. Their flavor is described as sweet but also salty, with a smoky quality to it.

Tomato Size

Black Krim tomatoes are medium- to large-sized fruit (6-12 ounces) with a somewhat flattened shape. The size and weight of the fruit makes Black Krims prone to cracking.  

Planting Zones

Black Krim tomatoes are frost-tender and do best in plant hardiness zones 10 and 11. They have been grown all the way into zones 7 and 6, although the cooler temperatures could affect the size of the fruit your plants will produce.

In climates with long growing seasons, you can plant seeds outdoors 2-4 weeks after last frost. Otherwise, start your Black Krim tomato seedlings indoors 6-8 weeks before the last frost (do research to know when this will happen in your area).

Size and Spacing

Tomato plants should be planted deeply with only the top 4-6 leaves showing. Moisten the soil prior to planting. Plant tomatoes 24-36 inches between plants.

Once planted, tamp the soil gently — do not compact it. Water your newly planted tomatoes thoroughly, taking care not to get the leaves wet. You may also apply fertilizer at this time.

Set up stakes or cages because the Black Krim grows between 4 and 6 feet tall.


Tomatoes are self-pollinating, which means you can grow a single tomato plant and still get fruit from it. They’ll also pollinate naturally with help from bees, birds, and wind. Greenhouse tomatoes may need to be artificially pollinated to ensure a crop of fruit.

Plant Care

Proper planting is only the start of things. You also need to know how to provide the ongoing care that your Black Krim tomato needs so that you’ll be rewarded with a healthy tomato harvest.

The following sections will provide highlights about tomato care. For a complete guide on optimal tomato plant care, from planting to harvesting and storage, please check out our article on How To Grow Tomatoes: The Complete Guide For the Best Tomatoes.  You may also be interested in our blog post on how to grow big tomatoes!


Tomatoes need a sunny, but sheltered, location where they get at least 6 hours of sunlight.  8 or more is better.


The soil tomatoes grow in should be well-draining and amended with compost and decomposed manure to a depth of 24-36 inches. For heavy or clay soils, raised beds with a soil mix tailored to the needs of tomatoes should be used for planting tomatoes.


Allowing the soil around your tomato plants to dry out puts the fruit at risk for cracking and splitting. Not only could this ruin the fruit, but it could provide a means for disease to enter your plant. 

Spread a 2-3 inch layer of mulch around your tomato plants, but keep the ground clear of mulch three inches around the base of the plant. Water on a regular basis and always water at the base of the plant to keep the foliage dry.


Tomatoes require specific nutrients (such as calcium) to produce their best crops of fruit. To learn how to determine what your tomatoes need and when they need it, consult our ultimate tomato fertilizer guide.


Pruning and pinching are a tomato care technique that can help your tomato put forth its best yield. But you need to know when to do this and what tomatoes need it. To help you with this, visit our pruning tomatoes guide.

Black Krims are known to be susceptible to blight and Fusarium or Verticullium Wilts. Experts recommend rotating the location of heriloom tomato plants each year as a preventive measure against blight and other diseases.

During the growing season, check your tomatoes often for signs of fungal infection. If you see any dead or dying foliage, remove and dispose of it in the trash.

To learn how to detect, treat, and take steps to prevent diseases, read our tomato diseases guide.


Tomatoes are often plagued by aphids and whiteflies. Inspect your plants regularly for signs of these tiny critters. If you find them, treat with powder, neem oil, or insecticidal soap (only when temps below 90 degrees F). Don’t spray your tomato plants with water to avoid risk of fungal infection.

Tomato hornworms are another tomato pest. Unlike aphids and whiteflies, they’re large and easy to spot. If you find tomato hornworms on your tomato plants, remove them by hand (they only look scary).

When to Harvest Black Krim Tomatoes

In August, start checking your Black Krim tomato plants for harvesting. Fruit that is ripe will easily release from the stems. Expect an average of 30 tomatoes per plant harvested over a period of about 30 days. You’ll need to visit your plants every few days to pick tomatoes.

Picked Black Krim tomatoes can be kept on the counter. They’re best if eaten within 1-2 days of picking.
