when to try prop. perennial flowers?
I'll be moving sometime over the next few months and would like to take some of my garden with me, if I can..:) I've tried, using cuttings/methods described in here and elsewhere, to root special echinaceas, phlox, veronica, and hellianthus, w/o success over the last few months. I expect some of it had to do with the excessive heat we've had.
Not sure, but think I read the best time to try rooting perennials is spring/early summer, or new/early growth. Is that true?
I'd much appreciate any info, or references that would help me decide whether to try.
