I apologize for this delayed reply to your gardening question. The spring rush has brought a deluge of questions and we are working hard to catch up!
I suggest you let those Plumbago plants go. You can cut them back but it really causes a delay while they regrow and get back into blooming again. Cut them back to the ground in winter. Next season cut back on the fertilizing watering a little to see if that helps minimize their tendency to over grow.
Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
