Q.creeper vine dying from top
What can cause a Virginia creeper or a creeping charlie to start dying from the top? Our creeper was so full and lush and is now dying from the top down. We did have problems with white flies early this spring with excess rain and now have a drought going on. We did spray the vine early on with a mild detergent and water mixture that we were told to use for the white flies. What can we do to save this for the rest of the summer?

Damp weather then followed by dry weather can stress plants and invite insects and fungus.
Virginia Creeper is generally a hardy vine and a vigorous grower.
I would trim back the vine. Then treat with Neem Oil
Neem Oil acts as both a fungicide and insecticide.
