Hi,
I've been having Buxus problems
Perhaps photos with clarify things.

The plants have been in this condition of some time now, even prior to
the hot spell we've been having in London and the Home Counties. I've
been keeping the soil moist with regular watering and was wondering if
it can be revived. It had not been watered for a while about 2 months
back, hence it reached this condition. Shall I snip of the brown /
golden dead leaves ? Re-potting ? Planting in soil ?
Any advice would be most appreciated. Thanks.

Uncle.
