Firstly hello one and all!
I am hoping for some help with a question I got asked today which I am
not really sure about.
A customer of mine has a fairly small (6-7 foot) Araucaria Araucana
which got tangled up last summer with a dose of bindweed. In order to
correct this he sprayed the bindweed with some weed killer. He is not
sure of the type of weed killer but i think it was more than likely
glyphosate based as the bindweed has clearly died off with no sign of
The Araucaria now has several patches of bron around the middle of the
trunk and on some limbs. I suspect is is from drift from the weed killer
He wondered if this has damaged it for good or if it is likely to
Can anyone advise from similar experience?

Hi Alex, My gut feeling is that it should be ok, no doubt he will end up
with a few branches that will be brown but it shouldnt kill the whole
plant. Luckily, most modern weedkillers now are inactivated on contact
with the soil so, even though its in the ground around this tree, the
active chemical will by now be locked away by the clay colloids in the
soil. He may have to cut out the brown bits just so that the tree looks
better but as you know, as these things grow, the lower branches die out
anyway, so even the damaged branches wont look so bad as it matures and
grows. As long as the top branches are not dammaged it will be ok and
even then, it would very soon put out a replacement leader. He should be
