Black Cherry Tomato

Most new tomato varieties are designed. Black Cherry just appeared.

In 2003, Vincent Sapp, cofounder of Tomato Growers Supply Company and one of the most experienced tomato growers in the country, found an unusual plant growing in his beds. It wasn’t the result of a planned cross. It was a naturally occurring mutation. One plant doing something different on its own. Sapp recognized what he had, saved the seeds, and introduced Black Cherry to the market.

Within a few years it had spread through the heirloom tomato community the way genuinely good things do: one grower recommending it to another. It’s now one of the most consistently praised cherry tomatoes in American home gardens.

Not because it’s the sweetest. Not because it’s the most productive. Because it delivers real complexity in a bite sized fruit. That’s rarer in the cherry category than you’d think, and it’s what keeps growers coming back to it year after year.

Why it’s dark, and what that tells you

Black Cherry gets its distinctive exterior from two pigment mechanisms working at once. As the fruit ripens, the flesh builds deep red lycopene, the same compound that makes standard tomatoes red. Simultaneously, the skin concentrates anthocyanins, water soluble pigments that produce purples and near blacks. Layered together, they create that characteristic deep reddish brown to mahogany color you see at full maturity.

Anthocyanins respond to sunlight. The more direct sun the fruit receives, the darker and more intensely colored it becomes. A cluster tucked inside a shaded canopy stays lighter than fruit exposed to afternoon sun on the outside of the vine. This means the color of your harvest shifts depending on where the plant is growing and how it’s pruned. More sun, darker fruit.

Those anthocyanins also carry a nutritional benefit. They’re potent antioxidants, present here in higher concentrations than in standard red cherry tomatoes. The dark skin signals something genuinely different from what a red cherry delivers, both visually and nutritionally.

What the fruit is like

Black Cherry fruit runs about 1 ounce per fruit. That’s larger than Sweet 100 and noticeably bigger than a standard cherry tomato, while still being small enough to eat in one or two bites. Fruits grow in long trusses, and a productive plant in full season carries dozens of clusters at once. A single loaded plant can produce hundreds of fruit over a full season.

The flavor is where this variety earns its reputation. Rich, sweet, and noticeably complex. There’s a smoky, earthy finish that you don’t get from standard red cherry varieties. Most growers who try Black Cherry describe it as a dark heirloom in cherry form, and that comparison is accurate. It doesn’t pop with the bright tropical sweetness of Sungold. It isn’t the high acid crunch of Sweet 100. What it has instead is depth, the kind of flavor that makes you pause before reaching for the next one.

The skin is thicker than most cherry tomatoes. This helps during picking since the fruit doesn’t split just from being handled. It gives a more satisfying, meaty bite. And it extends shelf life slightly compared to thinner skinned varieties. The tradeoff is that thicker skin doesn’t prevent cracking when water uptake is sudden, it just raises the threshold.

Seed packets typically list 65 days from transplant. Real garden experience runs a bit longer. Black Cherry is notably slow to start fruiting compared to most cherry varieties. Once production begins it’s prolific and sustained, but expect the first weeks after transplant to involve more waiting than a faster cherry like Sweet 100 would require.

The ripeness puzzle, and how to solve it

This is the question every first year Black Cherry grower ends up wrestling with in late July, usually while staring at clusters of dark fruit that look like they could be ripe or could need another week.

Standard color cues fail here. Black Cherry doesn’t turn a clean, unambiguous red at maturity. The exterior goes from green to deep mahogany. Green shoulders persist even at full ripeness. Waiting for uniform color means waiting for something that never comes, and a perfectly ripe cluster quietly goes over on the vine.

Use three signals instead. Feel: a ripe fruit yields gently to light pressure without collapsing. Firm means wait. The blossom end spot: look at the very bottom of each fruit. As ripening progresses, this spot transitions from green to orange to red. That orange to red shift is your most reliable ripeness indicator. Aroma: ripe Black Cherry develops a noticeably stronger earthy, rich tomato scent. Two or three of these signals lining up at once is your picking window.

The simpler approach: pick clusters at 80 to 90 percent color and let the counter finish the job over a day or two. Flavor is identical. You sidestep the cracking risk that comes with leaving ripe fruit on the vine through a rain event, and you stop second guessing yourself in the garden.

How to grow Black Cherry, start to finish

Starting seeds

Start indoors 6 to 8 weeks before your last frost date. Sow seeds a quarter inch deep in a clean seed starting mix and maintain soil temperature between 70 and 80°F. Black Cherry germinates reliably in those conditions, typically within 7 to 14 days. A heat mat under the seed tray removes the guesswork when early spring ambient temperatures are still variable and inconsistent.

Light is as critical as warmth at this stage. Set up fluorescent or LED grow lights close to the canopy from the day seedlings emerge. Keep them 2 to 3 inches above the top of the canopy and raise them as plants grow. The goal is compact seedlings with short internodes and stout stems. A seedling stretching toward a distant light source produces a long, weak stem that never fully recovers once it’s planted out. That early disadvantage shows up six weeks later as a plant that struggles to support its fruit load.

Pot up into individual containers when the first true leaves appear. Move from the seed tray into something at least 3 inches across. Feed weekly at half strength with a balanced liquid fertilizer from potting up through transplant day. Black Cherry is a vigorous grower that benefits from consistent early nutrition. A stocky, well fed transplant goes into the garden weeks ahead of anything that was stressed, cramped, or starved during the seedling phase.

Black Cherry is open pollinated and grows true from seed. Save seeds from your best plant each season. Scoop seeds and gel from a fully ripe fruit into a small jar with water, ferment for 2 to 3 days to remove the gel coat, rinse, dry on a plate, and store somewhere cool and dry until spring. Over a few seasons, your saved line drifts toward what your specific garden rewards.

Transplanting

Move plants outside after your last frost date, once nighttime temperatures hold reliably above 50°F. Black Cherry planted into cold soil sits still rather than growing, and cold nights increase the risk of blossom abortion before the plant is even properly established. Waiting for genuinely warm conditions produces a faster, healthier start than rushing the transplant by two weeks.

Harden off seedlings over 7 to 10 days before leaving them out permanently. Set them outside for a few hours on day one and extend the time each day. This adjustment protects against the shock of direct sun, wind, and overnight temperature swings that can set a young transplant back significantly just when you want it establishing roots.

At planting, bury two thirds of the stem. Tomatoes grow roots along any buried section of stem, and a deeper root system makes a large indeterminate vine dramatically more stable, drought tolerant, and capable of supporting a heavy fruit load through August and September. Pinch off any leaves that would be buried so nothing rots underground. Dig deep enough to accommodate the length, or angle the stem in a shallow trench and bend it upright at the surface.

Space plants 24 to 36 inches apart in rows 3 feet apart. Black Cherry is a vigorous vine with dense foliage. Crowding creates the warm, still, humid air that fungal diseases need to establish quickly. Give each plant its full spacing from the start.

Soil and feeding

Rich, well drained soil loaded with compost, pH 6.2 to 6.8. Work a balanced organic fertilizer into the planting hole before setting the transplant in. This slow release foundation supports the plant through establishment without forcing sudden growth that can stress developing fruit early in the season.

Once the first flowers open, switch to a lower nitrogen tomato feed. High nitrogen after flowering pushes leafy growth at the expense of fruit set. Black Cherry is already a vigorous, leafy grower that doesn’t need encouragement on that front once fruit production has started. Feed every two weeks through the season, including late summer, when the plant is still actively producing hundreds of fruit and needs sustained nutrition to carry on through to frost.

Moderate nitrogen matters throughout the season for a second reason. Excess nitrogen competes with calcium uptake, which increases blossom end rot risk on a plant producing hundreds of fruit at once. The calcium supply line to each developing fruit is long, and irregular nutrition disrupts it. Steady and consistent feeding beats sporadic high doses every time.

Light and water

Full sun, 6 to 8 hours minimum. The sunniest bed you have. More direct sun means deeper anthocyanin development in the skin and more intensely colored, more flavorful fruit. Partial shade extends days to maturity, reduces flavor intensity, and makes the plant more vulnerable to the disease problems it has no built in protection against.

Water deeply and consistently, 1 to 2 inches a week at the base of the plant. Deep, infrequent watering drives roots downward, making the vine more stable and more resistant to drought stress than frequent shallow watering would. A drip line or soaker hose laid at the base keeps moisture off the foliage, which reduces fungal disease pressure significantly over a full season.

Mulch is essential. Lay 2 to 3 inches of straw mulch around the plant after watering well. Mulch stabilizes soil temperature, slows evaporation between rain events, and buffers the wet to dry soil swings that cause cracking and blossom end rot. Black Cherry has thicker skin than most cherry tomatoes, but thicker skin is not immunity to cracking. A sudden surge in water uptake after dry soil will still split ripe fruit. Consistent mulch and consistent watering remove most of that risk before it starts.

Support and pruning

Plan for a large plant. Black Cherry is fully indeterminate and keeps growing until frost kills it. In good soil with a long season, plants routinely reach 7 to 8 feet and carry an enormous fruit load. Set a heavy duty cage or a pair of tall, sturdy stakes at planting time, before the roots spread out and before the plant needs support. Driving stakes around an established plant disturbs the root zone and the timing is always worse than getting it right at transplant day.

As stems extend through the season, tie them to the support with soft plant ties or strips of fabric. Nothing that can cut into the stem as it thickens. Check every tie every two weeks. A loop that was comfortably loose in May becomes a ligature by August if the stem swells around it. Wet foliage after a heavy rain adds substantial weight to loaded branches. The structure needs to hold all of that at once without the stem taking damage at the tie points.

Prune to two or three main stems by removing suckers below the first flower cluster. Strip any foliage touching the ground: it’s the first point of contact for soil borne disease spores. Above the first flower cluster, let the plant branch and develop naturally. Black Cherry’s productivity comes from those upper branches. Removing them reduces your harvest without improving fruit quality. The dense upper canopy also shades the fruit from sunscald in hot afternoon sun, which matters in warm climates where exposed cherry tomatoes can blister. Keep that canopy intact.

Expect a slow start to fruit production. Black Cherry builds root mass and canopy structure before committing to heavy output. First time growers often mistake this slow start for a problem and respond with excess nitrogen, which pushes more leafy growth and delays fruit set further. Hold the feeding schedule steady and let the plant move at its pace. Once production begins, it typically continues through to hard frost, often outlasting faster starting varieties by weeks.

Problems to watch

Fruit splitting. The main issue, especially during heavy rainfall after a dry stretch. Thicker skin raises the threshold compared to thin skinned cherry varieties, but a sudden surge in water uptake still splits ripe fruit. Pick clusters at 80 to 90 percent color before any forecast storm. Mulch consistently to buffer soil moisture between events. Our tomato fruit problem guide covers splitting, cracking, and other common fruit symptoms in full.

No disease resistance. Black Cherry carries no formal VFN or other disease resistance coding. Rotate beds each season, water at the soil rather than the foliage, and strip spotted lower leaves the day you see them. Early blight starts at the oldest, lowest leaves and climbs upward as summer progresses. Getting ahead of it early does more than any spray applied after the plant is heavily infected.

Slow first fruit set. Normal. The plant is building roots and structure first. First time growers who overfeed with nitrogen trying to speed things up push more leafy growth and delay fruit set further. Keep feeding steady and moderate, keep watering consistent, and let the plant run its own timeline.

Hornworms. A 7 to 8 foot vine loaded with dark fruit is exactly what they’re looking for. Check the undersides of leaves and look for stripped stems weekly. Dark droppings on the ground below a branch are the sign. Handpick or treat with Bt at first appearance.

Container growing

Black Cherry can grow in a container, but it’s a demanding container plant. The vine is fully indeterminate, growing all season and needing substantially more root space than a compact or semi determinate variety. A container that looks adequate in June can be completely root bound by August with most of the productive season still to come.

Use at least a 15 to 20 gallon container of quality potting mix. Set a cage or tall stake at planting. Water daily in summer heat since containers dry out dramatically faster than ground soil. Feed every week to 10 days because containers flush nutrients much faster than ground beds. Expect lower total yield than a ground planted vine with unrestricted roots. Flavor is identical. If a container is what you have, Black Cherry works. Just don’t undersize the pot.

Black Cherry vs the other cherry tomatoes

Sungold is the most direct comparison in most growers’ minds. Sungold is sweeter, fruitier, and consistently top rated in taste tests that prioritize sweetness. Black Cherry is less sweet and more complex. The smoky, rich depth is a different flavor category entirely. Both are worth growing, and they complement each other in the same garden rather than competing.

Sweet 100 is faster to first fruit, more productive early in the season, and easier for beginners. It’s a thinner skinned, higher acid cherry with none of Black Cherry’s complexity. They’re different tools for different priorities.

For growers who love Black Krim, Black Cherry delivers the same dark heirloom flavor family at cherry scale. Same color, same smoky depth, same complexity in a fruit you can eat out of hand without slicing. Our heirloom tomato guide puts the full dark family side by side.

The verdict

Vincent Sapp found something unusual growing in his beds and had the sense to save it. More than twenty years later it’s in gardens across the country because growers keep choosing it again the following spring.

Black Cherry isn’t the sweetest cherry tomato you’ll grow. It isn’t the easiest or the earliest. What it is, is the most flavorful dark cherry tomato widely available, and one of the few that delivers genuine complexity in a fruit small enough to eat out of hand without thinking about it.

Give it a tall cage, consistent water, and a full season. It starts slowly, produces explosively once it gets going, and keeps going until frost. Our growing tomatoes guide covers how to fit a long season cherry variety into a full season planting plan.
