Periwinkle - how to improve

We have a very old periwinkle growing over a dry stone wall, it does still flower but not a much as it  did before.  If I give it a severe hack back is it likely to improve the flowering for next year and if so when would be a good time to do it ?


  • Yes, do it. Take all the old trailing stems away, right back to the rosetted crowns. In the spring they'll burst up from the centres with flower and then new growth. You can do it now, then give it something well rotted and natural which will gently feed it preparatory for next season.


  • Thanks for your quick reply. I will start hacking it back next time I can get out in the garden.
