A lot of plants get those. Roses get them and your are supposed to cut them off, I leave them and I don't see any difference.........
So how is your corn doing? I planted mine late, close to the end of June, but it's starting to get little silks and ears growing. I'm so excited about it. None of my family gardens and it sucks, I want someone to be excited with me. I drag my husband outside everyday when he gets home from work to see the corn ears. He's so wonderful, he comments on it and pretends to care....... LOL
