Stipa tenuissima - comb or cut ?
I have a few stipa tenuissima plants that are now 3 years old. I've been advised to cut them back in spring but yet when I look it up, it says that you just comb out the dead growth.
I did email the Crocus about it and they said cut them as in the summer mine just get all wet and flop where as you don't see that at RHS Wisley.
Do I just need to be brave and cut them back ?
