My two alpacas got into my backyard and rubbed themselves all over my 5 pampas grass plants. They were scratching their backs with the sharp leaves. BUT now my pampas grass is not standing up anymore but appears all squashed down. It is still green. How can I revive it so it will begin to grow tall again?
As long as it is still green, it should recover just fine. If, however, the plant show signs of browning (or yelowing), I would prune it out. Thes plants are normally pruned back to the ground each year anyway, so if you have to resort to this, it will not hurt the plant.
