My sunflowers are all in a row, right out in the open, to act as a "living wall" in between my patio and lawn. I get nervous when it's really windy during a storm, and have lost a couple that have been blown to the ground. Should I stake the rest out? I was thinking of putting a stake on either end of the row and then running string from one stake to the other on one side of the flowers, then tying off and running another string about a foot higher on the stake on the other side of the flowers. I'd keep adding support strings as they grew higher. Does this sound crazy or will they be OK with the wind when they are tall and heavy with a flower?
