well, my sunflower is growing in sun taxes where it gets lots of heat and sun, I water regularly but not excessively, any ideas on what's happening to her leaves?
Not an expert but when mine started to look like that I gave them a dose of Epsom salts. Just scratched it into the soil around the plant and watered it in. The plants greened up nicely. I never measure but if I had to guess I probably used about 2 teaspoons.
