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.
