Can glyphosate be used to kill the vegetative growth near the ground
without killing the entire tree? It wouldn't be a disaster if I did
kill it, but it'd be better not to. If I kill it I'll be duty bound
to remove it, and that looks like a big job 8-)

Glyphosate applied in sufficient amount to kill some growth is likely to
kill the entire plant. If you are in southern California, just wait. A
blight is killing oleanders from San Diego all the way to Thousand Oaks
and is likely to spread farther.

Is there any hope just west of Sacramento?

Yes, it will be several years before the blight can spread that far.
Perhaps, it will take long enough that a cure or prevention might be
discovered before then.


I can be patient. In the meantime, the only method I know to suppress
stump sprouting is light-tight covering, which is difficult in this case.
The oleander actually belongs to a very understanding neighbor, but their
mow-and-blow service will likely remove deep mulch and a solid cover will
be both difficult to fit and unsightly. Is there a better way?
