Cutting back & propagating creeping phlox
I have some patches of creeping phlox that are along a sidewalk and have taken over a good portion of the sidewalk. I would like to cut them back and also propagate some for other areas of the lawn.
I have tried dividing the clumps in the past but I always end up with a bunch of dead looking branches underneath and leading to the green stuff I actually want to move.
So first I was thinking I would trim them back - mostly along the sides and just a tad on the top. The tops look fine they have just spread too far. How aggressive can I get in cutting them back? If need be can they be cut back to the ground (or a couple inches of the ground)?
Then I just read you can propagate by stem cuttings so I was thinking I would take some cutting for some new beds I am building. When is the best time and what is the best technique for this?
Thanks for the help everyone. I read here a lot and only post occasionally but always get great responses!
