Hi Penny,

Sorry it took so long to get back to you.  I'm not an expert with Roundup.
I too sometimes find that I can't pull up the weeds when they die back from
a dose.  I just figured that the root system is so dense or so deep that it
can't be pulled.  I just pull what I can and if sprouts reappear (which
usually happens), I reapply the Roundup.  

The Copper Shield is from Gardens Alive and it is supposed to stop
blackspot and other fungus.  I usually get powdery mildew on my monarda and
roses so that's why I'm trying it.  It's been so cool here though that even
my usual toadstools aren't sprouting.

Good luck in the rock garden.
