Can we see some pictures ?

It's hot here, 95-100+ every day, nighttime around 60.

That's a biggie, and also 35 to 40 degree temp swings imply wicked dryness.

Do you have flowers without fruit, or is it a lack of both? These plants in full sun all day? You also have a break in the weather coming right about now, don't you?

Don't forget the pics.

I will try to upload some more photos, but here's that for now! :)

We are in a historic drought in California. It's crazy dry here, and with the late summer fires it's also pretty dusty and hazy. But they had a darn tomato festival here last month, so I know someone is growing them successfully!

I have lots of flowers! Not as much as earlier in the summer when there were tons, but there are still a lot. Some of them wither up completely, and then others, the yellow blossoms wither but the green part that should be the top of a tomato looks good.

Last year it was still in the 90s at Thanksgiving, and then it turned cold pretty quickly. The year before that, we got some fall weather around the beginning of November. The plants are in full sun for most of the day, probably from about 9-4.

Thanks for the help!

Here's a full shot of my super classy raised bed. Be kind, it was my first garden ever. :)

I've been stalking these guys for weeks. It looks like there should be a tomato in there, right?

I'm sorry all these photos are sideways. They're directly from my phone and I guess that's just how they upload.

Lots of good looking blooms.

I think it's probably too hot, since I think tomatoes set fruit best when temps stay below 85 or 90. You're obviously getting blossoms.

In some cases too much nitrogen in the soil causes more vegetative growth rather than fruiting. Was there a lot of nitrogen in the potting soil you used in the bed?

Keep them watered, and fertilized. When the high temps drop to below 90 they will start setting fruits. Heat kills pollen so they will continue to grow, but won't set fruit until the heat wave breaks.

How many tomato plants do you have in that space? To me, it looks like there are dozens and dozens. The leaves are quite small too...are they in full sun? The excessive heat might have something to do with pollination, but the plants should be growing nicely if all other conditions are met, i.e enough water, nutrients, air flow, spacing, etc.

I cannot judge the quality and health of your plants based on the pictures, but I think one of the possibilities for not having fruits can be high temperatures. So if you are getting consistent temps over 90F, then it is likely that your plants are aborting (aka blossom drop).
Just a brainstorming type of thing :-)

"The leaves are quite small too...are they in full sun? ...but the plants should be growing nicely if all other conditions are met..."

There's an enormous difference between your zones 2 and the OP's zone 9, and one of those is that high heat can cause a chunky stocky indeterminate to get all wonky thin. The plant can also have a hard time recovering from that state when the weather breaks cool after sustained high heat. Maybe it's just emaciation.

Maybe this can be eased by changes in watering/shading/fertilizing. Maybe not, I dunno, but it also tends to produce weeny rooted clones. Again, this happens only to some people in super hot/dry areas. Right now I have one Sweet 100 that's over-summered, a few more that were layered from it in the dirt, a couple that were rooted in water from cuttings from it, and some more that were grown from seed started in July. The mama plant is one sick puppy (that may or may not pull through fruit-wise), the outdoor clones are skinny, the seeded starts are chunky, all except mama are flowering, and there's not a hint of fruit in sight.

Hey, it's an experiment and the dirt's not being used otherwise, but the point is that sustained heat, lack of fundamental soil moisture, and very dry air can smack tomato plants silly.
