Perriwinkle Care (Vinca Minor)
I live in zone 9 in South Louisiana.
I have several Periwinkle plants in a small garden. There's been no sign of life this spring, all I have is some dead looking stalks. Should I cut them back to the ground? What can I do to encourage them to grow. I do plan on adding some new plants this year.
Thanks,
Carl

Yes, cut them to the ground and add some liquid fertilizer like 10-5-5 or similar, in a small dose. Dig one up and look at the roots. Are they living ? They like dappled shade...do they get some ?

It's hard to talk about time since you didn't say where you are located but it's been such a cold crazy winter in much of the country that I would wait a couple weeks later than usual before doing anything drastic. I'm in NC and only starting to trim dead material which is a good couple weeks later than usual.
I would not dig up a plant just to look at it's roots. You'll subject it to transplant shock and set it back several months. Just look at the plant above ground. If you want to trim off the dead start at the tips and snip off a bit. If it looks dead on the inside then move further down and take another snip. If you get to a point where there is some green inside the stems stop cutting even if the leaves appear dead.
