Thanks, Guy! Fortunately, the one I have the most of is the morning
glory. No flowers on it yet, but I'm sure they'll be along soon. I
wonder if all the cloud cover/rain has retarded their blooms.

Looks like I'm in for a real battle with the bindweed, but I'll get on
it. Probably a war I can't win as it's out by the road near my
entrance, and I'm out in the middle of nowhere.

As for the poison ivy, this little bit is all I've detected. I'll cut
the vine at ground level and zap it there.

Greatly appreciate your help!
