  1. Yellowing Tomato Leaves Maybe Normal:
    High Temperatures?

    Yellowing leaves can be a sign of different issues that may be effecting
    your tomato plants. There are disease and fungi that create leaf patterns
    that may turn leaves yellow. There are nutritional issues that may turn
    leaves yellow. There are insects and pests that, you guessed it, will turn
    your tomato plant leaves yellow. Those reasons are reason of concern and
    often merit a specific treatment or response from the gardener.

    There are however, other reasons for leaves to turn yellow that aren’t red
    or should I say yellow flags of alarm. Determinate variety tomatoes die out
    once they reach a set height and set fruit. That is a normal yellowing and
    life cycle of the tomato plant. The video highlights my indeterminate
    varieties of tomatoes and follows 4 planting areas of the ‘Brandywine’
    variety tomato. With 7-10 days of 95-105 degree heat and nearly 100%
    humidity… a healthy tomato plant responds. That response is often
    yellowing leaves. And that is nothing to worry about. The tomato sheds
    leaves knowing it can fall over, set roots to the ground from its stem and
    grow strong again. It doesn’t know we have it staked up.

    You do have to make sure you keep the basics going. Make sure they are
    being fed, watered and inspected and managed for diseases and pests. When
    all those thing are in check… sometimes yellow leaves are normal. The
    ‘Brandywine’ always gets yellow leaves and ‘leaf die out’ come the high
    heat in my area. My new variety ‘Matt’s Wild Cherry’ is yellowing heavily.
    Around this yellowing tomato are healthy green tomato plants that have been
    cared for the same way. The only difference is the heat, humidity and how
    different tomato varieties respond to the climate in your Zone. There is
    something you can do and that is to try out different tomato varieties each
    year and remove varieties that do not do well in your Zone.

  12. ooops ….forgot to say thanks

  13. My husky cherry tomato leaves are also yellowing. I am also in zone 7.
    Thanks for the info, I was a little worried.

  14. i also have a tip, always grow multiple of the same variety and keep the
    seeds from the biggest, healthier and most producing to ensure good genes
    in future crops.

  15. I am think of creating something like that next year.

  16. 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.

  17. Yeah, all those container tomatoes where the frost damaged. They did great.
    I slacked off on pruning to let them grow. And they did nicely.

  18. I’ve had like a dozen on there at once. Its very cool looking when that
    happens.

  19. thanks gary!

  20. 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.

  21. I agree. Do the basics and notice what your tomato do in the weather of
    your zone.

  22. 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.

  23. awesome. i’ve been watching a couple of mine a week now yellowing and was
    thinking negative. thanks for the post

  24. I’ve learned yellow can almost mean anything. Glad you did a video in it,
    the first place I start is a dose of cal-mag and that usually takes care of
    it and helps prevent blossom end rot as well. Thanks for sharing ;)-

  25. Nothing on the tomatoes for caterpillars. I have only seen 2 or 3 hornworms
    in years. Not that I want to jinx myself.
