Question: I have bermudagrass in my trailing juniper groundcover bed. How can I get rid of it without hurting the junipers?
Answer: Probably the best way would be to pull and hoe as much of it out as is possible, then put a layer of roll-type mulch in place around the plants. Juniper groundcovers don’t root into the ground as they trail, so you can snug that type of covering up around the plants’ stems. Overlap the pieces by several inches, so the grass can’t grow up through the seams, and cover it with 1 to 2 inches of pine bark mulch. You will have to hand-treat any grass that comes up near the stems with a glyphosate or similar herbicide. Apply it with a foam rubber paintbrush to keep it away from the junipers’ stems.
