Fernleaf - leave well enough alone?

| Last Fall I planted a fernleaf recovered from a neglected garden. It bloomed this spring and did well but has a couple of other plants' roots intertwined with its roots - a lysmachia, for example. The peony's rootball is about 10-12" across and the other plants are coming up from the middle. I sprayed the lysmachia with Roundup (regretfully, but I considered it an emergency) when the fernleaf was dormant. The Roundup doesn't seem to have affected the lysmachia - maybe too cold out? Now I'm wondering if the aggressive roots might still be strangling the peony roots. Should I leave it and see what happens next year, or should I dig it up and try and separate the roots? Here in Z4, I'd consider this mid- to late-fall. |

| I would go ahead and dig it up and separate the weed roots out. That would be better than spraying round up again next year. Fall is the best time to dig and replant or dig, divide, and replant peonies. You say your fern leaf peony has a 10-12 inch root ball. That may be large enough to divide in half. Be sure to leave 3-5 eyes on each division (or lots more). If you get some smaller divisions with eyes that break off, go ahead and replant those as well. If you want to get rid of those weeds, now is the best time of year. Good luck! |

| Do not be surprised if your fernleaf only has one eye with a bunch of roots. The finest leaf ones show this trait until very established. I agree to get the other roots out at this time. |
