So the Japanese beetles got away from me and have entirely defoliated 7 of my 42 new vines planted this year, while only 2' or less tall. A number of other vines are hanging on by a thread, with a few leaves. I'm wondering: if a new vine is hit that hard with all its leaves destroyed so young, can it bounce back or is it a lost cause? Should I be scrambling to try and replace these vines ASAP this season? I've had some Japanese beetles past years in my garden, but nothing to this magnitude. I had no idea they'd be that much more attracted to grape vines than anything else I've ever grown at this location.
