Last year I put a plumbago plant into my wash tub of flowers and it did great. This year I repeated it and now most of the blossoms have gone and all I have is a spindly looking plant If I cut it back will it grow more flowers this season? This is a new plant, not the one I had last year. I live in KY

Cut back all leggy stems or branches that detract from the plumbago's overall shape after each flush of blooms. ... Reduce pruning to just removing spent flowers six to eight weeks before the average first fall frost date in your area.
