I had to yank out one of my lantana last year. I didn't fertilize, but I did throw new dirt into the bed and replanted. It was AFTER it was growing pretty good and no frosts happened to zap it. It just needed a soil change. My lantana is coming out now, and I have been snapping and trimming dead ends as it usually just comes back from the roots. However, that gold lantana is coming back along the branches too. Good luck with yours.
