I have a beautiful zebra grass. I was wondering if I should trim it in the fall or wait until the spring. Thanks!
Honestly, it makes no difference to the plant whether you trim it now or in spring or at all for that matter. If you don’t like the way it looks now (straggly) then trim it back now. I would probably leave it until spring so the dead foliage will catch some leaves ans later snow to help insulated it over winter but Zebra Grass is so hardy that the choice is yours. Peter Bowden
