We got some pampas grass that has already been dug up

Question

Should we go ahead and plant it as it is fall here,or should we wait till spring? I don’t want it to die.

Answer 1

You should plant it in pots and bring it inside for winter. Unless you know that you have a "hardy" pampas grass (more cold tolerant than the standard varieties), it is not suitable for your climate.
