I have had a coreopsis (presto) in a sunny spot in my front garden for about a year, it was in good health up to a few weeks ago. It had seemed to survive Winter quite well, but now I’m not sure what has happened to it. It has not been particularly cold lately, it was definitely much colder during Winter.
It looks like it’s collapsed from the inside or something crushed it as there was a few partially broken branches/stems, I have removed any completely dead segments and this is the remaining plant. The leaves seem OK but none of them plant seems to be upright and supporting itself, am worried that it's slowly dying but there hasn't been much progress in it either dying or coming back to life.
I’ve been watering it regularly along with the rest of the plants around it, everything else is fine. Not sure if I should cut it back or leave it and hope for the best
Thanks for any advice,
