I just used the hedge trimmer to cut dead flowers and long stalks off of

That's a big one! Any time from now until spring.

I can't keep any of those Mediterranean woody labiates going very
long, because they all die from root-rot. It's generally a good
idea to renew them regularly, and layering works well. But whether
'not very long' is 5 years or 50 is entirely dependent on the
conditions. I should do better, with well-drained soil, but I
don't - and I am pretty sure that it's some unidentified fungus.


It's funny you should mention that but we can't seem to get Sage to grow on
our allotment. Grows for a year or so, even flowers well, and then just dies
back, does not seem to make any difference if it's in a pot or in the
ground. Yet 3 allotments along they have three large plants which have been
there for years. I'll have to ask for some cuttings and try them.
