What to do with Phlox after flowering
I planted what i sort of remember was a phlox in a tub a few years ago and was wondering what to do once it has flowered. It has flowered really well again this year. Do i need to cut it back at some point and can i chop it into several plants later on in the year as it is getting a bit full in the pot. Am i also right in remembering it was a Phlox?
