many tomato blossoms are not turning into fruits

[grasswire]

It's my understanding that indeterminate tomatoes do not require pollinators. Many -- probably half or more -- of the blossoms on my sungold maters are not converting to fruit. What's up with that? I'm used to seeing full bunches.

1. too hot maybe

over 90deg. some of them stop setting

2. No tomatoes require pollinators (perfect flowers - pollinate upon opening) - so something else...

Could be the plant is setting what it can handle as far as available nutrients (you never get all blossoms set), though could be impacted by heat or humidity (yet that is much more of an issue with larger fruited types).

3. Many tomatoes will not set fruit if the temps are too high.

When it cools off a little, they will usually start getting fruit again.

4. thanks everyone!

It's probably the heat, then. I have them growing in containers, staked up against a white wall that gets a lot of heat. I'll be sure to do a lot of feeding to sustain the growth. The two sungolds I have eaten thus far were sooooooooo good.

5. Has it been above 75 degrees at night? Tomatoes will not set in excessive heat.

6. Determinate or indeterminate, they still need pollinators. How's your bee population?

They're not the only ones. Flies, moths, butterflies, hummingbirds, and even random beetles and spiders will pollinate. Our yard is full of clover so we're flooded with bumbles and honey bees this year. Any sign of blossom-end rot on the fruits that do set? If so, their feet are too wet. It's been a weird season.

9. I was surprised to see some people didn't think they needed pollinating. My squash didn't get

pollinated last year. I have planted several "bee friendly" plants, and this year everything is fine.

10. no really, nralieghliberal is right

tomatoes are self pollinating.

11. Wait a minute. They don't require another plant (like kiwis), but nightshades do require pollinators

Some plants have to have two different plants (and in the case of kiwis, a male and a female), but a lone tomato plant will produce. In that context it is self-pollinating, but you still have to have insects to distribute the pollen between flowers. Bumbles do the heavy lifting on our nightshades. I've never heard of a plant producing without pollinators. Perhaps I have some research to do.

7. It may be the heat. Last year

I had tomatoes that ripened in November because fruit set in September.

8. It is the heat

day time temps > 94 degrees for a period of time cuts down the pollination %
