  • Hi there Bruce, They are best planted, divided and moved in spring. They do not tolerate moving or division as well in the fall.

    My landscaper recommends both cutting them down to the ground and/or separating them in the early spring before everything starts growing. For us in SW Ohio, that would probably be late March or early April. :-)

    Yep, spring time is the best time to cut back and or divide your ornamental grasses. They don't like to be transplanted in the fall either. I learnded this the hard way in Pennsylvania one year when I moved some ornamental grasses in the fall and they all died as I remember it.
