Does anyone know if verbena is killed off by frost/snow? The ones in the front are back as they always are, the ones in the back, which were in pots, aren't. Could the winter have done 'em in? Thanks GerryMumsnet
my mum took cuttings over the last year - stuck the cuttings in water, they rooted and sprouted, took cuttings off the top of the cuttings, etc. Ended up with 20 of them. So - yes, cuttings seem to work well.
Have you tried cutting them back hard and being very nice to them? Ours are coming back (in flowerbeds) but there's a garden round the corner where they're all in full bloom. Am quite tempted to knock on the door and ask how they did it.
If you want to protect plants in pots you can wrap fleece or newspaper round the pots, which can help, or just bring them in.
