Newer growth works better than old growth so later
in the season means it will not work as well or takes longer. Sometimes
it takes a few days to a week to see that the plant is dying. Things
with many roots and runners can be harder to kill.


That's for sure. I am fighting what seems to be a neverending battle against
honeysuckle, which took over all my shrubs and some trees last summer before
I realized how bad it had gotten--and it killed several rhododendrons and
other stuff.

Last year I spent two full weekends pulling, cutting down to the woody stem
at the ground, and dipping the main plants in pure roundup concentrate. That
was followed by application after application of strong roundup
concentrate--but it keeps coming back. Basically I have an acre of woods
that was pretty much a solid CARPET of honeysuckle (and some wisteria-type
vine) underneath, and it had completely covered two sides of a large 6 foot
chain link fence.

I can't ever let my guard down, because of course I can't keep it from
leaping across the creek and property boundaries.

BUT it's under control, off my shrubs and fence, and I will prevail!
