Growing Sunflower

View the Sunflower page

18 May 18 Carol Graf-Haslam (USA - Zone 10b climate)
When should I plant Mammoth grey stripe sunflower seeds? I live in Southwest Florida and the temperature can range from 32 for a few hours during the winter with highs in the mid to Upper sixties but starting in April the temperature goes into the 90 +range. Should I plant them in October or November 4 a January crop or plant them in March for a May crop? I don't want them to burn and I don't want them to freeze. Please help. Thank you and I am glad to see that the friends in South Africa are also in the same predicament as I am.
