planting Karl Foerster grass in the ground

Question

Can I plant Karl Foerster grass in the ground, leaving the pot intact except for the bottom? I want to keep the grass contained in nice clumps that will stand upright. Is there a way to keep them from spreading haphazardly?

Answer 1

Karl Foerster feather reed grass has an upright growing pattern, and this cultivator is not invasive.
It will not spread with additional seedlings.
I would not plant using an open bottom pot for these reasons.
