I've got two Griselinia littoralis shrubs in containers. Some of the
smaller, younger leaves on both plants have turned partially black, and the
black parts are limp. Would that be due to all the rain or recent weeks -
or something else? Are the shrubs in danger of dying, and should I cut off
all the affected leaves?

This plant is susceptible to phytophthora ramorum so one thing you
need to check is whether this has appeared in your area.

Discounting that though, I would guess that your shrubs are pot bound
and getting stressed. Grisselina is a thuggish plant when it gets
going and will root deeply and grow vigorously. It's very hardy in the
ground but in a container it can be susceptible to wet and cold. To be
honest, I wouldn't think of it as a container plant. On one estate I
manage it was planted en-masse as hedging and the landscape
contractors are chopping a foot off it three times a year at least.
