If the brown leaves are staying on the shrub rather than falling, this
can indicate other problems. Alas, this is where my senior moment kicks
in so I can't remember the cause/s :~(. Sorry. Hopefully, it is just
drought-induced defoliation.

Good luck.

I was taught years ago that leaves going brown and leaves dropping are
two different processes. The lesson went something like something
tells a plant to slow down for the winter, the leaves stop doing their
job and change colour. After a while the plant notices this and as it
doesn't like hangers on it drops the leaves. In between we have all
the autumn hues. The bigger the plant, the longer it takes for it to
notice that the leaf is getting lazy as there's further to
communicate. Trees are the biggest plants which is why they hold the
autumn leaves longest.

Simple but sounds good to me.
