Many tomatoes here WILL set fruit when the temps are over 95 - we have some dynamite native bees that can pollinate them. Mine didn't stop last year until August - they finally wore out in the 110+ temps. They were in afternoon shade and mulched very heavily.

Anything that is set will continue to ripen.

Be VERY careful about watering. If you are erratic, your changes of "Blossom end rot" (which is not really a 'rot", just tissue damage) go way up. Regular watering, preferably with a drip line under thick mulch.

They'll continue to grow to a point, and then split when the heat becomes too much. When you see the first one split, pull all your maters (even the green ones) and ripen in a brown paper bag. Cherry and grape tomatoes are generally an exception to this, and they'll finish on the vine just fine.

Thank you Lazygardens & Kojac_phx. That is very good news to me!

I have an heirloom beefsteak & a couple of Cherokee Purple that have set lots of fruit but I was worried I might now get the very tiny tomatoes to fruition. All three plants are on a drip system, in pots on the east side of the house with some trees around. My Green Zebra & Mr. Stripey are taking FOREVER to set fruit. I'm afraid I might not get a bountiful harvest from them.

I'd love to post some pics here of my plants, but don't know how. :-(

When it gets hot I usually put shade cloth over my plants and they continue to grow tomatoes,however I don't think they set much fruit after 96 degrees.They do fine until the monsoon's start then the tomatoes rot very easily.I guess the heat and humidity is too much for them.

Sounds like good advice to me. the real trick on tomatoes is to start them in October, and keep them though the winter (frost protection) that way you have nice vines ready to load up as soon as it's warm enough to set fruit.

Ok, I now know how to post a link to my photos. So here are some pics of my tomatoes! What do you think?
