Do You Trim Dianthus pixie

Do you trim the dead flowers after bloom?
Doug says - yes. Simply prune or pinch off the dead stems as low to the rest of the plant as you can. If you pinch off the seedpods, you'll have a bunch of ugly "sticks" sticking up over the plant. Pruning off the stems lets the leaves show up over the rest of the summer and you can hope for a bit of a rebloom. :-)
