Requesting help with verbena, please?
I live at 9000 ft. My Pink & purple verbena were doing great in my large planters on my deck. However the leaves are turning brown now. Too much water. Not enough. I water thoroughly every other day. southern exposure. Use bloom booster weekly. Any help would be greatly appreciated. As I have a lot of $ invested already in these planters. Which I'm sure all of u can relate . Thank you, (tried to upload pic but option n/a)
