Q.trumpet vine is not yet showing signs of green
I have a trumpet vine that is not yet showing signs of green. It is covered in dry brown clumps of leaves. We had a late blizzard this spring which damaged many trees. Do you think it might be dead, as it was subjected to late spring cold?
Trumpet Vine should be hardy from down to Zone 4.
Nearly the entire United States suffered below normal winter temperatures. This may be the cause of the loss of you plant, not necessarily the late spring blizzard.
Trim away any dead material and see if any new growth may appear.
I'm still seeing loss and damage in my garden this spring. I understand the frustration, but sometimes the loss makes for new planting opportunities!
