Questions About Sunflower Plants

    I have seen squirrels and groundhogs start climbing a sunflower until it tips over from their weight. (I'm sure we can add raccoons to the list.) Then they bite off the seed head. But I think you'd be able to see their teeth marks so that probably isn't it. Is this wind damage - something like whiplash? Some people stake sunflowers. Of course, severe lack of water/heat stress might weaken the stem. Are these all the same hybrid? Obviously, I'm struggling to find the answer. I would dig up one of the affected plants and inspect it carefully including an exam of the roots. If you find nothing, I would let the seed company know.

    A leaf spot disease could be a virus or bacterial disease.
    I would suggest removing the plant and discarding.

    That Is a case of albinism. This is almost always fatal in plants. It lacks the ability to produce chlorophyll, which is what gives the plant its green color. This is also necessary for photosynthesis, which means the plant will die soon. It can't make energy for itself very long.

    You have a seed with a genetic defect. It will die since the plant can't do photosynthesis with white leaves.

    Thanks, BushDoctor. I had been googling descriptions and images for the past 2 weeks. I was thinking Sunflower Midge, but wanted to ask as this is my first time growing sunflowers :) I never saw any caterpillars, but maybe because I cut them off before they had time to mature.

    Most eating varieties are classified as either tall or giant.
    Look for “Mammoth Russian” or “Russian Giant,” two popular eating types that grow from 10 to 15 feet tall with seed heads 12 to 24 inches in diameter. “Kong” is another type that grows to 10 feet, with smaller heads. “Aztec Gold” is a popular eating variety. For a small garden, plant “Sunspot,” which reaches only 2 feet in height but produces 10-inch seed heads. Other types include “Jumbo,” “Giant Grey Stripe” and “Paul Bunyan Hybrid.”
    We do not recommend specific businesses, do a Google search for these seeds!
