Hi, I'm new at growing sunflowers, and need some help please. I purchased "Perry Morse" Mammoth Sunflower seeds. I planted them according to directions in early March. They are rather tall now, but the heads are all drooping.
My questions are:
1. Should I tie the heads to the stakes? If so, how tight?
2. How much water should they be getting now?
3. Bugs..... I have been trying to keep the bugs off of them, but am having trouble. I would say that I have on 3 sets of plants at least half of the bottom leaves are chewed through.
4. When will I know when their done?
Any suggestions or help would be greatly appreciated. I live on the West side of town (Litchfield Park).
