After receiving almost 3 inches of rain over the past 5 days, long term weather forecast is for many rainless days with day time temperatures ranging from 95F(35C) to 105F(40.5C). Nights will be at or above 75F(24C).
Tomato’s and Peppers stop pollinating and blooms drop occur when:
Daytime temperatures greater than 32° C (90° ) Pollen sterility occurs, flowers may drop.
35° C (95° F) Much reduced fruit set .
Night time temperatures less than 15.5° C (60° F) or greater than 24° C (75° F) will result in poor fruit set.
Take extra time to check your garden. Cucumbers, squash, zucchini and okra may need to be harvested every morning. A good rule is harvest while young, smallish and still tender.
It is the time of the year tomato horn worms are hatching and are active eating your tomato vines. Check your vines very carefully.
Late evening is a good time to find and remove horn worms as they come out of hiding from the days sunshine and heat and began feeding on your tomato vines.
As temperatures rise and rains are less frequent, observe you garden for signs of drought stress. If plants look stressed, drooping leafs in the early morning you may need to increase your irrigation schedule to 2 or even 3 times a week to your plants healthy.
Heavy mulching around your plants will help in weed control, reduce moisture loss and keep soil in your plants root zone cool.

I’m wondering if tomatoes can be adapted to lower nighttime temperatures. Here they have been consistently below 15 degrees C but I’ve still got fruit.
It’s good to know about the effect that excessive heat might have, anyway.

OSU, University of Oklahoma and Texas A&M University ‘experts’ say tomato’s and peppers may well produce crops, at lower or higher temperatures, but they are not ‘optimum’ temperatures and in general pounds(Kilo’s) per-plant will be much reduced and fruit quality may be effected as well.
Enjoy the fruits of your gardening efforts and Happy Gardening.

We have had so much rain this June … can’t complain … this time last year we were in drought. It is a problem I love having. On another thought … I agree … common sense is uncommon !!!

Weather service claims our average rain fall is around 30 inches a year, but, over the past 10 years it has been closer to 18 – 20 inches than 30 inches. We have spring rains when we get most of our moisture and another wet spell in mid to late fall.

I envy you those 3 inches of rain, but it sounds like they’ve already evaporated long ago.

Don’t be misled, I wouldn’t want to live any where else, but, my soil is mostly a tight clay based soil, hence if it does not rain slowly over a long period of time a good part of any rain runs off into the local creeks and ponds. On the other hand clay soils are good at retaining moisture once it has had time to soak in.

I wish we could swap a wheelbarrowful of clay for one of sand. We’d both be happier mixing them into our soils.

Grin… you have a trade. Then you can make bricks and clay pots and I will have a sandy base to plant my garden.
