I have an ornamantal grass (fescue i think) which has been in a pot for a few years now,but this year,the frosts have turned the blades yellow.
I know im probably supposed to give it a haircut,but several years ago,i did this to another and the whole thing promply died! Its gonna have to come out of the pot anyway as you cannot actually see it anymore,but am reluctant to trim because of what happened last time.Dont wanna loose it because in summer-it looks like a big green cushion and is a good size (2ft across).
Any ideas as to how i can keep this one alive after trimming???
