I like to do a bit of gardening, and I'm trying some sunflowers this year. Here in northern Virginia, we've had an interesting summer so far, with frequent heavy downpours and wind the past several weeks. I guess that has something to do with some of the sunflowers falling over, but not all of them are falling. Anyone know a "trick" that I'm missing? How do you keep your sunflowers from falling over, even with rain and wind? Oh and they range from about 6 ft to 12 ft tall so far; the ones that fall are not just the real tall ones.
