I've just planted a Phlox Paniculata (Flame) and reading on line the advice is to cut back to the base in autumn.
Does anyone know if this advice holds true to a relatively newly planted plant?
Hi SmudgesDad I have brighteyes and leave mine as they are, the stems go white and look great with the winter sun on them!
I leave them in autumn and cut down some time in Spring when I am tidying up for the bulbs to come through.
You can cut your phlox back in the autumn, but like fb I tend to leave it until the spring, then at least I can remember where they're planted. Cutting it all back to the ground in autumn I can't remember where stuff is in the spring, but if I leave the stems I know where not to dig.
