I’m in Cincinnati, OH. My climatis blooms abundantly in the late spring and then a few blooms come during the summer. I’ve even seen a couple in the late Fall this year. Is it OK to trim the plant back this late (Nov. 17th)? It’s 52 degrees F. today, going down to 45 tonite. Tomorrow, high 61 with rain and high winds, low 34.
