Getting the tops of willows to mature
Hi. I live in southern Wisconsin.
I grow willow plants and I want the tops of the plants to stop growing and mature by early in October. I use these for a religious holiday.
The problem is that the plants keep growing and producing baby leaves at the top. As soon as I snip them, they start to wilt.
Instead, I'd like them to stop growing and fill out at the top. A farmer friend suggested growth regulator and perhaps the addition of nitrogen. What do you think?
