Kuum Tomato Grower Reviews and Photos

A tall variety, hitting 6.5 feet (2 m) and higher in the hoop house. It’s a heavy yielder and ripens early-to-mid season. The fruits are very large, red, and oblate. Very tasty, juicy, and sweet.

I grew it in 2013 and put it back on my grow list again this year. Almost all the tomatoes were uniformly around 7 oz (200 g). I really like that it’s early, tasty, and productive.

Absolutely loved the taste, it’s one of the best out of all the red varieties.

This year I planted two bushes in two different greenhouses. Seeds were from Redko, 2013 stock.

I’m pruning them to two stems. One plant already has 25 large fruits on it, and the other has at least that many. It’s a very worthy variety. I’ll be planting it every year. I’ll take some photos tomorrow.

I’ve grown Kuum two years in a row and I’ve been completely amazed by it both times.

Early, delicious, and a super yielder.

Not only does it ripen ahead of everyone else, but it pumps out a massive amount of large tomatoes while doing it.

It puts out a literal wall of fruit on the plant.

It’s staying in my collection forever.

The only downside is that right at the very end of the fruiting season, it can be susceptible to gray mold.

I highly recommend it to everyone.

Very good, reliable variety. Stable yields, and it didn’t drop its blossoms in the heat, which is a highly valuable trait for me. And it’s very tasty.

I plant this variety every year. I love it for its taste, earliness, and solid yields.

The fruits are red beefsteaks, sweet. They are usually the very first to start ripening in my greenhouse. Depending on the weather, they start blushing in late June or the first days of July. The plant has a mixed generative-vegetative habit. The foliage development is pretty moderate. It blooms heavily, which shows its great yield potential. But I will admit it does drop blossoms during the July heatwaves, since I don’t run shade cloth over my greenhouse. Despite that, the final yield compared to other varieties is still excellent. Indeterminate. For me, it doesn’t quite reach the roof of the greenhouse.

Planted Kuum for the first time in 2019. I loved it. Got over 20 large, tasty fruits per plant. Disease resistant. I saved seeds from it and… lost them lol.

I plant 2 bushes of Kuum every year. I really love it. Mamina Lyubov also got a permanent spot in my garden just like this one.

I’m growing this variety this year, and I am just not seeing these giant tomatoes. All my fruits are hovering around 7 oz (200 g). There’s no wall of fruit either. Maybe it’s because of the heat, the entire middle of the bush is empty. But why is the weight so low? Meanwhile, the plants right next to it have absolute hogs hanging off them, and I feed them all exactly the same.

Sergey, these were from your seeds…

The abnormal heat is what did it. The fruit weight dropped for me too compared to 2018-2019.

Yields across all my varieties ended up being just average.

Kuum ended up being mid-season this year instead of early, though it still gave a decent yield. There was no wall of fruit – the heatwave really took a toll.

My whole family ate some Kuum tonight, and the tomato itself was super watery and bland. And that’s despite me not watering the greenhouse for 3 weeks.

It’s just been a bad year for my tomatoes, and that includes Kuum.

How many years have you been growing Kuum? Did you actually like the taste in previous years?

T@tk@: “How many years have you been growing Kuum? Did you actually like the taste in previous years?”

I’ve been growing it since 2018. I loved the taste, its super yields, and how early it was.

It’s a very good variety. It’s just that because of the extreme heat, most of my varieties only managed to set two or three trusses. The only exceptions were Babushkino, Mamina Lyubov, and Zilbert, which managed to set four or five trusses.

I will always grow Kuum, it’s permanently in my top five.

Kuum. Indet, reliable heavy yielder. During a bad summer, stuck in a less-than-ideal shady spot in the greenhouse and pruned to 2 stems, it still loaded up with a ton of excellent red oblate fruits. Weights ranged from 7 to 14 oz (200 to 400 g). Excellent, balanced tomato flavor.

You always need reliable red varieties like this in your arsenal. Things like Babushkino, Roza Stasa, Borisovna’s Red Heart, Borisovna’s Red Giants, Serovskie, Kuban Red, Giant of Khakassia, Slastena, etc. They are workhorses for every occasion, from fresh salads to processing. Productive and low-maintenance. And most importantly, they have simple, familiar names that warm a Russian heart lol. The other day I practically broke my tongue trying to pronounce “Crnkovic Yugoslavian”.

Seeds from @Nata N. Thanks!

Kuum. Grew it in a poly greenhouse in 2019. Really liked it. Tasty, beautiful uniform fruits, and a heavy yielder.

Kuum is an indet. A fairly old, well-known slicer variety. The tomatoes are large, ranging from 7 to 14 oz (200 to 400 g). Red, meaty, juicy with a classic tomato taste. The flesh is dense, not mealy at all. I was refreshing my seeds this year.

This time I planted it in a spot with medium sunlight. It didn’t drop its blossoms like it used to when I had it baking in full sun, and the bush got so heavy it literally slid down its support string from the weight of the fruit. Good boy! Very productive variety. It pumped out fruit from mid-July all the way to the end of September.

As they say, you look at tomatoes like this and your eyes just rejoice!

I grew Kuum in 2025 and really liked it. It tastes better than Dzinovsky Yabukar, and the yield is higher too.

Svetlana (Svetikk), thank you!

Forgot to add that I grew it out in the dirt. The bush is quite vigorous, almost 6.5 feet (2 m) tall. Stayed healthy right to the end, no blossom drop, didn’t beg for extra potassium. The fruits didn’t shrink down in size as the season went on, they stayed almost perfectly uniform. Didn’t see any deformed monsters or megablooms on either of my bushes.

Just saw my old post here from 2020, so I decided to update and defend Kuum’s honor! Yeah, it was clearly just a bad weather year back then. I’ve grown this variety twice since then from my saved seeds, and both runs were highly successful. It’s a great, low-maintenance, heavy-yielding variety. Classic flavor, not bland at all, plenty of sugars and just enough tang. Meaty. They aren’t massive giants, but they consistently weigh in around 10.5-14 oz (300-400 g). My husband absolutely loves them, it’s the perfect size to slice up for a meal.

Overall, a fantastic variety for both fresh eating and all kinds of canning/processing!
