do i cut the dead foliage back? help!
i am fairly new to gardening. i bought a house in haddam, ct (zone 6) and it has a lovely wildflower/cottage garden along an old fence. some flower varieties in it are black eyed susan, coneflower, russian sage, monkshood, hyssop, delphinium, bellflower, and foxglove. since everything died back in the fall i left the dead foliage standing, afraid of what to do, and unsure of what the previous owner did. people have told me this is okay as it adds winter interest. my question is, what happens in the spring? do i leave all the dead stuff or do i trim it back? and if i do trim it back, do how low do i go? and in what month does this take place? i really want all of these plants to survive so that i can keep this beautiful garden for years to come. any advice would be greatly appreciated! thanks!
