Virginia Creeper Problem
Doug says:
By the end of June - most plants should have leaved out. If yours hasn't then my guess it's dead. This is pretty uncommon for this plant if it survived its first year but generally speaking, it really isn't that late an emerger.
My .02 on this kind of question is that I give most plants the benefit of the doubt until mid-summer and then I pronounce the last rites over them on the way to the comost pile.
With this one - or any vine for that matter - I'd suggest you examine the base of the plant carefully because sometimes you'll get a top die-off and the plant will throw shoots from the base.
