Way too hot for cukes and strawberries...the toms should take off huge once it cools down a bit.

Re cherry tomatoes, yes, if they're indeterminate, and you can keep them alive, they'll start producing again. Sounds like you may have planted them kind of late? Survival in the heat is more likely if they're only four feet tall. It's the really big vines that have a hard time pumping water when it gets really really hot.

Cukes are more heat tolerant with fruit set. If you have male and female flowers, you ought to have cukes. Maybe do some manual pollination? I believe that cukes often respond to high heat by putting out mostly male flowers, though.

If the plants are in relatively good health and you mulch HEAVILY(and I mean HEAVILY) and maybe provide some shade cloth, you just may be able to keep them going until it cools off some and they kick back in.

I pulled mine after nursing them along for several weeks in extreme heat with no results. The problem with keeping them in was that temps are not expected to moderate here until the end of September and that's a long time to try to support the plants without any yield. Now I have time to plan for my fall planting and the garden has time to rest. I live on the Gulf Coast and I think of our down time as being July and August, whereas in cooler climes, it would be December to March. Also, my experience with fall plantings of the veggies that are usually Spring planted has been inconsistent because of the nature of the seasons' turning here. We will have extended spells of mild temps followed by abrupt temp drops when the cold fronts blow in, followed by yet more mild temps. It plays havoc with the spring type vegetables. I will be planting things that can tolerate these kinds of fluctuations. Getting them to germinate in the still hot days of late summer and early fall will be a challenge, but I have some ideas and am slowly amassing what I need to implement them.

I'm with ya there about the difference in gardening philosophy in the south compared to the north. Exactly right about July and August. I agree about fall plantings, in that the seasonal temperature profile in the fall is different than in the spring. It gets cooler in the fall faster than it gets hotter in the spring. Fall plantings are therefore somewhat more of a challenge than spring plantings.

Most years, I am unable to keep crops going through July and August, but this year seems better, perhaps because of occasional rain and slightly moderated temperatures.

I'm putting in bush beans in the next few days, (for the first time in mid-summer) and I think the challenge will be getting the seedlings to survive. But if they do, I'll be sitting pretty in October.
