Perennial grass grown in a pot

Question

Can the grass be left in the pot over the winter?

Answer 1

The care will depend on your growing zone and the hardiness of the perennial grass that you have planted.
Potted grasses can generally be moved to a shelter location, such as a garage or shed.
They can be wrapped with winter protection blankets to keep the roots from freezing.
