Yellowing Tomato Leaves May Be Normal: High Temperatures? - The Rusted Vegetable Garden

Tips, Tricks

1. My tomato plants are producing flowers but there is no tomato. the growth of the plants are very good and the temperature is 32 degree celcius-36 degree,also the weather is very humid.What is the reason for this?
2. Hi Gary,
   
   Thanks for this video. I just fertilized my tomatoes last week and was a bit surprised that on couple cherry tomatoes, the matured leaves on the bottom were turning yellow. I was getting ready to give them more fertilizer...glad that you mention it's the heat! I did prune off the yellow looking leaves (even though they were disease free leaves), but now wondering if it was necessary. I can't wait for my echinacea flowers to bloom!
3. Just prune out the yellows leave that's what I do.
4. Thank you for the information. I had thought maybe I was watering to much. I didn't even think about the heat.
5. Gary?
   I repotted they pulled out of leaf curl then a few turned yellow in grow room?
   They are super crispy ( Roma's )
   But the tops are fine?
   I did a cycle of fertilizer it appeared that after that this went north?
   Sigh
   
6. tomatoes are tropical? tomatoes are one of the hardest plants to grow in the tropics.
7. I am think of creating something like that next year.
8. Nothing on the tomatoes for caterpillars. I have only seen 2 or 3 hornworms in years. Not that I want to jinx myself.
9. noticed the lovely patch of echinacea with butterfly's all over them, what do you spray your tomatoes with as a preventative for caterpillars? peace
10. Yeah the lime wouldnt change things that fast. The heat and rains put the plants into survival mode. Hopefully they hang in there till the temp breaks and they perk up again.
11. I was going to post a question about this in the Google group. My Sungold tomato leaves turned yellow. Curiously it was the morning after I did the lyme treatment, so I thought I did something wrong. It is very hot here in Georgia and it's pouring rain every day. The plants are still producing very nicely so I guess that it's the heat. Thanks for the video. It eased my mind. I love those tomatoes. I definitely want them to produce for as long as they can. 
12. having the same problem here in Turkey, this summer is so hot and temperamental, all of my plants had difficulties growing
13. ooops ....forgot to say thanks
14. Q 1- What tom var. is to the right and left of your yellowing cherry tomato? The ones with the hugh fruit...:31..."they do pretty well in the heat" Q2- My tomatoes are green and full of flowers but hardly setting fruit...could that be heat related, or rain we had earlier?
15. I've had like a dozen on there at once. Its very cool looking when that happens.
16. Was it a 'heated' argument. Yes pun intended.
17. Tomato plants are simply amazing. They are remarkably resilient and have all sorts of built in mechanisms in their DNA to make the best of the situation that they are given.
18. wonderful, thank you for settling an argument here. We have had a hotter than normal few weeks here and my tom's have been yellowing like yours. I'vebeen telling hubbie it was a heat issue, but he wouldn't have it.
19. awesome. i've been watching a couple of mine a week now yellowing and was thinking negative. thanks for the post
20. I like all of the monarchs on your coneflowers.
