Tomato Varieties We Tried in our Hoophouse

Each year we grow two 96′ (29 m) beds of early tomatoes in our hoophouse. We plant them mid-March, start harvesting at the end of May, and pull them up at the end of July or beginning of August. By that point the plants have reached as high as we can go and the outdoor plants have started producing large amounts, so we don’t need to ask more of the hoophouse plants. Each year we grow varieties that we’ve had years of success with, plus a few new ones.

Last year I wrote My favorite tomato varieties, about the four we trialed then: Pink Boar, Geronimo, Cherry Bomb and Estiva. We decided to grow Pink Boar and Cherry Bomb again, but somehow we didn’t! Pink Boar developed more splits and more disease in the last few weeks as the season reached its end. Cherry Bomb was out of stock when we placed our seed orders, so we tried another red cherry, Sakura.

Sakura is a 55 day indeterminate red cherry. It did well, resisted disease. But when I checked why it didn’t seem very productive, I discovered that a confused planter had planted only one Sakura and an extra Black Cherry instead! Next year, maybe we’ll try Cherry Bomb again, or try really planting two Sakura!

We stopped growing Stupice, a 62 day indeterminate red, in favor of

more Mountain Magic, 66 day indeterminate reds. A plan is just a plan. Somehow, a bunch of Black Cherry (64-75 day indeterminate purple) got substituted for some  Mountain Magic and some Garden Peach at planting time, due to more worker confusion. We love Black Cherry, but they take longer to pick than larger tomatoes. Some might argue that Mountain Magic at 2 oz (56 g) are not that much bigger then Black Cherry at ½-1 oz (14-28 g), but as you see, they are at least twice as heavy. The disease-resistance of Mountain Magic, Glacier and Garden Peach was medium this year.

None of us missed the Stupice, with their green/yellow shoulder problem. As I noted last year, the lack of red lycopene in the shoulders might be due to too much heat. We did try not pruning the Glacier (56 day determinate red) at all this year, and we got less of a green shoulder problem with those, so that’s worth remembering. We’d like to keep that one, as it is so fast at ripening. Sungold is still faster, though catalogs claim Glacier should be one day ahead.

This year, I wanted to try several large red round fast-maturing tomatoes, and a couple of different colors. To be chosen for our hoophouse crops, tomatoes have to mature in 80 days or less. Our main red is Tropic (80 day indeterminate red). It’s good at setting in heat and has a good flavor, but this year had a lot of disease. This summer has been peculiarly mild, up until mid-August, so not a good test of heat-setting tomatoes.

Skyway tomatoes from Johnny’s

We tried two plants each of Skyway (78 day 8-12 oz (112-168 g) indeterminate red) and, for the second year, Estiva (70 day indeterminate red). Both looked impressive: big shiny unblemished fruit. But no flavor worth reporting. Estiva had good disease-resistance, and split resistance, but was slower to fruit than the 70 day claim.

We planned to try Premio (60 day 4 oz (56 g) indeterminate red), but didn’t get any seed. Maybe next year?

Mountain Fresh Plus tomatoes from Johnny’s

We did try Mountain Fresh Plus (75 day determinate large 8-10 oz (112-224 g) red, short plants) for a second time. “The most widely-grown market tomato in the East and Midwest” Johnny’s Selected Seeds. We are a fan of many of Randy Gardner’s “Mountain” series of tomatoes, but not this one. It wasn’t very productive, and the flavor wasn’t exciting.

 

Tropic remains our main red slicer.

Jubilee (80 day indeterminate orange) is our main orange slicer, and that did very well, with medium disease resistance this year. The fruit looked a little different this year. Possibly we were still sowing seed we bought during the pandemic, which came labelled “Probably Jubilee”. It’s also called Golden Jubilee.

Mountain Spirit tomato from Fedco

We also trialed Mountain Spirit (77 day indeterminate large yellow/red) and Purple Boy (80 day indeterminate large purple, Park Seeds). Neither of these wowed us much. Production was low and flavor was only so-so. We had hoped Purple Boy would be a good substitute for Cherokee Purple, which splits and yields poorly in our hoophouse. Mountain Spirit had a mushy texture.

I’m concluding (provisionally!) that large fruited tomatoes are not such a good idea for us. We do better with more productive, more modest sized tomatoes.

We came up with an idea to reduce the chance of misplanting in future. We didn’t want to write labels for every single potted tomato, so we have been labeling just the rows of 3 or 6 in a standard 1020 flat, which holds 18 pots. This means we often have more than one variety in a flat. We have small numbers of purple, brown and green pots, so we can use those for particular varieties. Mostly we have the standard black pots. Our new idea is colored dot stickers, which are often to be found in our office is oddly large numbers. I wonder if anyone else ever uses them?

My favorite tomato varieties

Over the years I have developed definite preferences about some tomato varieties, and I also enjoy trialing a few new kinds each year. We do our experimenting in the hoophouse, where we can keep a closer eye on the plants, and keep the labels visible (few weeds!)

New this year have been Pink Boar, Geronimo, Cherry Bomb and Estiva. Two of those I want to grow again, and two can fade into history.

Pink Boar is a beautiful fruit, with olive green strips on a wine-red background, and dark red flash. The flavor is sweet, tangy, rich and juicy like Black Cherry and some of the other dark-fruited tomatoes. The plants are vigorous (some say “aggressive”) and productive, although I do notice a bit of a tendency to split. Not big messy splits like Black Prince, but manageable if you pay attention to harvesting them when ripe. It may be our “beginner problem” of not knowing their ripeness signs as well as the other varieties. I recently told one of our crew “close your eyes and press the bottom of the fruit.” If it’s at all soft, it’s ripe. I learned this years ago from a completely blind friend who grew a garden.

75-80 days to maturity, indeterminate OP, 2-4oz (56-112gm), 2-3 inches (5-7 cm) in diameter. They were bred by Brad Gates from Black Boar and Brown Boar, as part of their Wild Boar series. I hear they grow OK in Texas. You can buy the seed from High Mowing, Baker Creek, Peaceful Valley, and Wild Boar Farms, the breeder himself.

Cherry Bomb is a firm, bright red cherry tomato with a sweet, well-balanced flavor. The 64 day, F1 hybrid indeterminate plants produce good handfuls of ripe 15-20 gm fruits at each harvest. They are not prone to splitting (unlike Sun Gold).

Cherry Bomb has a high resistance to late blight. We have rarely suffered from late blight, but I like to grow a few resistant tomatoes just in case. And we have been looking for a tasty reliable red cherry. This might be it. Cherry Bomb is sold exclusively by Johnny’s Selected Seeds, who rate this variety for outdoors, not just hoophouses. It’s out of stock until August 2023, so it must be popular!

We love Sun Gold, Black Cherry and Five Star Grape, but have still been searching for another cherry. We weren’t wowed by Washington Cherry or Riesentraube (gave those up after one year). Initially, we were taken with Amy’s Apricot, but we lost patience with its variability. It’s tasty, and a nice one for those growing only a few plants, who like surprises. But we have enough confusion, and want more predictability.

We appreciate Mountain Magic more each year! We have been growing Glacier and Stupice as early hoophouse tomatoes for years, but the green shoulders are off-putting. Glacier is a 56-day OP determinate with potato-leaf foliage and good flavor. Stupice is a 55-60 day OP with potato-leaf foliage, but is indeterminate. From suppliers’ photos you wouldn’t know these two varieties get green (or yellow) shoulders, and the descriptions often don’t mention that either. Some particular varieties are more prone to green shoulders and there is also a weather component. When these varieties are in sustained high temperatures (hoophouses!), lycopene (red color) production is reduced, and when direct sun beams on the tops of the tomatoes, temperatures inside the fruits rise. Perhaps we’ve been pruning them too much.

Another factor is that at high temperatures, chlorophyll can’t break down, and the red color is hidden. The yellow color is carotene, and it is more heat-resistant than lycopene. We’re ready to wait a few days longer, and have fruit that are red all round.

Mountain Magic is a 70-75 day indeterminate red 2 oz (56gm) hybrid, from breeder Randy Gardner in NC. It is productive, beautiful (no cracks!), trouble-free (resistant to both early blight and late blight, as well as Verticillium and Fusarium wilts) and, importantly, delicious. It looks a bit like Amy’s Sugar Gem, but is more regular, and has a better flavor. This year we increased the number of Mountain Magic and cut back on the Stupice and Glacier. Next year we will probably grow a higher proportion of Mountain Magic again. And stop pruning the Stupice and Glacier we do grow!

Not quite ripe yet! Jubilee tomato in late June.

Jubilee (also known as Golden Jubilee) is a lovely medium-sized orange 80 day indeterminate OP we have grown every year for a long time. Beautiful, meaty, delicious sweet fruit. Disease-resistant and crack-resistant. The seed has been harder to find since the start of the Covid pandemic. One year we even bought somebody’s home grown seed that arrived labeled “Probably Jubilee”. It was close enough under the circumstances. Reimer, Eden Brothers, Willhite, Victory, Sandia, Hoss Tools and Bentley have it currently.

For more Tomato Appreciation, see Craig LeHoullier’s Tomato Collection Tour. I linked to part 6: numbers 51-70, because Craig mentions Valencia, a selection of Sunray, which was selected from Jubilee (a stabilized cross by Burpee between Marglobe and Tangerine). In my search for a good reliable tasty orange tomato I have at some time tried almost all of these, without knowing their family connections.

Craig says his “Grow Every Year” category includes Cherokee Purple, Cherokee Green, Cherokee Chocolate, Polish, Lucky Cross. Others, such as Brandywine, Dester, Ferris Wheel, Yellow Brandywine, Anna Russian are grown in his garden every other year.

Our workhorse red slicer is Tropic, a heat-tolerant, disease-resistant 80-day indeterminate OP from the University of Florida program. Good sweet flavor, 8-9 oz (225-250 gm) fruit. The Southern Exposure Seed Exchange selection is available from Wilcox. Other suppliers of Tropic include Urban Farmer and TomatoFest.

If you are searching for heat-tolerant varieties, as we might all be wise to do, to face climate change, peruse the TomatoFest site Tropical Hot/Humid Tomato Seed Colleciton.
