You have to be very careful, it is absorbed by any green parts of a

got it on or drench with water.

I accidently sprayed a young potato, drenched with water within 30
seconds....no good, dead tatty

Oh I was rather hoping strong woody bushes might not be so vulnerable
but it seems not

Not summat to be messed with eh?

Definitely not. But it can be used with proper precautions, and is a
valuable tool in a large garden or park. As well as to kill stuff like
bindweed that is difficult to dig or pull completely.

Woody stems don't absorb glyphosate, so it can be used with reasonable
safely around established trees or shrubs. If you get any on the trunk,
it is not absorbed easily. My neighbor sprays it right on the trunks of
his cherries to clear the area around, with no problem.

Martin's advice about not using to fine a spray is very important,
because any drift will be deadly.

Another thing I do is to mix in a blue biological marker, so that I can
see very easily where I've sprayed. That way 1) I don't waste the
product when doing the drive, and 2) if I make a mistake, I can quickly
see and snip off the leaves that have gotten the stuff on them. The
marker disappears after a few days.

I always wonder about the trunks on young trees that can still be green
like young fruit trees and young Holly trees.
