What could be the problem - the temps in the greenhouse. Most likely far too hot and that means non-viable pollen. What are your average daytime and nighttime temps in there? What sort of cooling system are you running. Got your shade cloth on? What % of shade are you using.
Zone 7 GH growing this time of year is nigh on to impossible due to the internal temps.

I bought an early girl at home depot before the flowers were on it... kind of a small plant then. I have 5-8 tomatoes on it currently. The first tomato doesn't look like it's going to get any bigger and it feels like it is taking forever to turn color ( weeks now) and it's still as hard as a rock. In mean while 2 cherry tomato plants are turning color.
I hope this early girl puts out some more flowers and tomatoes... I was expecting more off of it. I only bought this as a back me upper incase my heirloom plants didn't make it.
Between what I don't eat fresh and giving some away... I plan to sun dry them. I've never canned before, but I LOVE sun dried tomatoes... I can't keep them for long... I eat them like potato chips.

For future reference: Don't put 12 tomato plants in a tiny (1.5 square meter) spot (who knew they would grow like this?!)

Yeah, right. If you do, you have to keep them trimmed/pruned.
I do very tight planting myself but in 1.5 meter square I would plant 6. Max 8 smaller ones. Even then, I keep my plants pruned. Here is a picture of one.
One main doubled. Then each of them doubled. Now there are 4 branches growing upright ; no side branches/suckers are allowed to grow. This one is the one with maximum branches, Four, NO More.
I realize that there are those who do not prune. That is their choice and style. But in small space gardening it will be a tough task.

Nice plant. I'll definitely prune them next time. I did look it up earlier and came to the conclusion that it was not necessary (which suited me, naturally). Then they grew and grew and grew: I put up a greenhouse and within a month they went from 30cm dying plants to 2m dying plants.
Upon your recommendation, last week, I hacked away some of the smaller suckers, but it's heartbreaking to do anymore. I copied your frame-style supports because it fit into the existing structure without having to put stakes through the roots. I also did a bit of florida-weave around the central ones and some fence-tying on the far ones. Much effort put into rescuing these 12 falling plants; and now I've left them in the hands of my housemates for a month. I'll let you know how the tomatoes turn out, if any do come out.

Another strange thing that happened to me this year... Bakers Creek sent me an empty cucumber packet with a large order I had made. I don't know how the order picker didn't know it was empty.. seems obvious to me. They shipped me 2 packets of it that week.
But the packet of black sea was labeled that on the plastic envelope. I never bought from that seller before on amazon... won't be doing business again.

I was discussing this with the sample lady at the grocery store (I will talk to anyone!). I have a row of San Marzano, and a row of Chocolate Stripes, 25 of each, right next to each other. Both varieties started from seed, by me. The Stripes are producing BIG, both in fruit size and number. The San Marzanos look like large pear shaped cherry tomatoes.
I am in South Central KY, she is a good 100 miles away in NW Tennessee, having the same issue with San Marzanos! Hers were bought as plants.
No answer, sorry, just commiseration!

I agree with one of the other posters that it's best to take the tomato plant out of its container (no matter which type of container) prior to transplanting. I go as far as to break the root ball to "free" the roots. Otherwise, you get a limited root system and small fruit. Nurseries sell products to prevent transplant shock, and while I'm sure they don't hurt, they're probably not 100% necessary.
Since your plant is in the ground, you could take something like a yard stick or similar device and poke it into the ground as far as it'll go and it might help break the bottom of that biodegradable pot and maybe free the balled-up roots.

Picked my first one last night! Not entirely ripe, but since rain was predicted for today, I didn't want it to split. It was one of my mystery tomatoes from my Glacier seed pack. A little over two ounces. Have more blushing on the same plant and fruits start to blush on both of my Stupices! So excited to start having ripe tomatoes!

I would say it's probably alright, I think it's sterilized. More information in the link below and you can decide for yourself.

Yeah given all the controversy about it its one decision you'll have to make for yourself. Personally I'd compost the grass clippings with lots of other stuff before using it around food crops but that's just my opinion.

I have read that tomatoes should be fine in pH range like 5.6 to 7.2 but 5.2 would be way too low. I would add fast acting lime. Probably the soil test has also made some recommendation on how to deal with low pH situation. I would shoot for like 6.8 as optimum level for 99% of garden vegetables. But anything from 6.2 and up should be fine in the short run.
OTOH, changing pH takes time and cannot be done overnight. The best time is in the fall , to add lime and let it work.

Could this be my problem?
Definitely. Plus compost isn't going to neutralize soil pH within one season and most compost has a pH of around 7 not 8. 3" of compost will decompose fairly quickly and the soil will return to its native pH.
Dissolving some lime in water to use on the plants may get you through this season but I can't begin to know how much or how often. You'll have to let the plant appearce tell you if it is working or not.
Then this fall consider liming the soil well so it has time to work before next year.
Hope this helps.

Hey Walkie,
The pot is too small.. And on top of that it seems to only be half way full.. You could try to transplant but that would be difficult now and larger transplants don't take too well.. If it were me I'd prune up the first 3-4 nodes (branches) and fill the pot to the brim with soil.. In the future - 10 gals and up .. Good luck =)

I would have started it early, topping the mains and letting lower laterals to take over. But probably it is not too late. It is only early summer.
The winds knocked down my Mortgage Lifter. Its branches were like 8ft but only 6ft supported. Now, I let them drape but I pinched all its growth tips. I'll see what happens.

Carolyn:
These are all new varieties for me. It was not my intention to smear TF. I know things happen and I'm sure they would not be in business as long as they have if this was a common occurrence. I was freaking out a little I guess as I was looking forward to these varieties and not knowing exactly what I had. As far as my end I can only say I am very meticulous, but of course mistakes can happen. After looking at the opalka plants with suspicion for a long while I noticed that my SMR were getting very long and slender and then finally they were unmistakably opalka. I thought then maybe I had made a mistake so I looked up the growth habit for both and they were indeterminate and what was supposed to be opalka were determinate. Also the Anna Russian were noticeably wrong. I think the Italian Heirloom are probably right. They are decribed as pear shaped and while a few look like hearts most are oblong with slightly pointy ends but more oblong than pear I would say. I will look again at the NAR as they might not be completely ripe. I was going to wait until the other varieties showed color before I reported anything. I was just wondering if anyone else was having any problems. From Baker Creek I got Green Zebra, Cherokee Purple, Kelloggs Breakfast, Pantano Romenesco, and Stupice. All of those excluding KB (which have not blushed) are looking good. Also I grew Yellow Brandywine, Black Krim, German Pink, and another variety that I got as a local heirloom that are all looking good. I will gather more info and see if I can figure anything out on my end but it looks like some are not showing true to anything that I was growing.

Upon further review:
I think the NAR are OK. I was either looking at the wrong plant or thought it was blushing pink. I have one on now that looks like it will be red.
I think what I thought was Italian Heirloom are in fact Anna Russian. Wispy foliage and the immature fruit are dead ringers on tatanias database. They were early as was reported. I would say they are more orange red than pinkish red though.
So either I have blundered badly, but only with the seeds from one vender or they are mis-labeled. All the packages are identical except for a printed label. I am going to try to start more seed and see if I can get them up big enough to at least identify them if not get some mature fruit. It's going to be pushing it with average first frost being early to mid-October. I do hope it was my mistake. I will report my findings. Thanks Carolyn.

There are two kindsof Powdery Mildew so I'm asksing where, specifically are you growing your tomatoes,in a geographic sense,such as coastal CA, coasta lFL, hot humid south with plants too close together or otherwise
,so it might help if you did that.
The treatment for both is the same,a good anti-fungal, but first take off and dispose of all affected foliage before you treat with any ant-fungals.
Carolyn

Yep I did prune as much as i can, as for the whole GMO thing I dont even understand it, I just want to use a pesticide/fungicide that not going to have me keel over if i eat my own tomatoes lol. As for why I want a "3 in 1" spray is because I am a newcomer to gardening. Much like my mature plant paid the price when I just jumped into using miracle grow.
I see some occasional bite holes, and the powery mildew is indeed on my two youngest plants. But Im trying keeping it simple as possible. Thats why i went with the tomato spikes. Helped the Nitrogen burnt plant recover and flourish. Meanwhile keeps me error free.
Also Im in the midwest,Nebraska to be exact. we've had some unseasonably friendly weather. Its late july and were are hitting 70s tops. Usually in the 90s. Sparse rain, but here in the midwest anythign we get...is usually too much lol.

Nothing you can do given the situation in the pic except some massive pruning which will only make problems worse for all. I'd root some cuttings from the one you want to save and then plant them elsewhere. It is still early enough in the season to get some fruit from them. Meanwhile leave this one alone and see what it does. Consider it a good learning experience for the future.
Dave

Thanks Weicker and Dave. I appreciate the fast responses.
I never thought about a later setting variety. It makes perfect sense though. I know it doesn't look it but there wouldn't be much pruning except to remove some of that flowering cilantro(the trellised vines of the loner plant are right there). I may try that and root some cuttings but I will leave everything else alone.
This is all one giant learning experience Dave! I think that is what I enjoy most about gardening outside of the satisfaction of growing my own food. :)


I have had this problem this year and so have 2 other friends that live 10 miles and 12 miles away. I took my leaves & soil the CSU diagnostic lab and they said it was herbicide damage from contaminated horse and cow manure! The worst part is that the hay meadows were sprayed with herbicide to kill thistles, the animals ate the hay, the herbicide went through unchanged, the manure was 6 years old. Dang! It was still toxic to tomatoes even after being in the environment that long.
We washed all the soil off of the damaged tomatoes and repotted in potting soil. They really didn't improve but the new plants in potting soil are fine.
The people in the lab said that the fruit is PROBABLY okay to eat.... DANG again!



Kumato is a hybrid variety developed by Syngenta in Spain and Western Europe as a result (per Syngenta)
"Developed through the natural crossing of a wild and domestic tomato" (parentage unknown except by Syngenta).
and seed distribution is heavily controlled by the corporation to a group of highly corporate-vetted commercial growers in only a few countries (primarily Australia) for commercial sales.
It was marketed in the US only recently under a different name - Russo Bruno if I recall correctly - with the same controls on the seeds..
Lots of info available about it on the web.
Dave
Below is a picture of my Kumato plant.
One this is for sure that it has a vine growing habit very much like cherry/grape tomatoe. Its branch stretch out very long and tall but the branches are thicker than cherry plants.
Since I planted mine as an experiment from store bought fruits, I am not sure what I will get. But so far the fruits are more plum shaped than round. The fruits that I bough were the size of a big cherry, maybe 2 oz each.
I wonder how OP's plants are doing, in terms of production and fruits shape/size.
