I have a major problem concerning concerning new shoots for my bushes. I
live in Winnipeg, Manitoba, Canada..... (500 miles north of Minneapolis, Mn)
I have been growing roses for over 40 years and this problem is killing
me....
All of the new shoots(before the bud head) are being chopped off like a
cut worm cut. I have been dusting regularly, but after two days
whoever/whatever is back right at it.I have not seen (or heard) a single
insect around my bushes , yet every morning the shoots are disappearing.
And yes, the whole shoot is missing, nothing on the ground underneath or
around.
What on earth is it? Some kind of night flying leaf cutter bee? The
weather and temps have been normal this year and last. I'm at a loss as to
what it is or how to stop it. Otherwise, roses are completely healthy.
Your comments here would be most appreciated.

Thanx
Don
