Does glyphosphate work alright at this time of year?.

No. It is a complete waste of time and money spraying glyphosate in
mid winter onto tough perennials. It needs sunshine and active
photosynthesis to inflict sufficient damage on the growing plant. It
will probably still harm anything delicate you accidentally overspray
even in modwinter, but it won't kill tough weeds.

Unless you want to kill couch grass in amongst leafless thorny shrubs
when it can be just about useful (although even that works better in
early spring when the grass is growing but the shrubs are still
dormant).

I have some bamboo shoots around the garden and I wish to terminate the
bamboo. Is it better to just cut down the shoots (they all have leaves
on) or to spray with the glyphosphate? Thanks for advice.

You will get much better results in early spring as the stuff is
starting to actively grow.
