My search feature is not working, so I'm asking something that I'm sure has been asked before. I live in south Tx and want to find a good grass for my outdoor enclosure (for a leopard tortoise) . I was going to do a pasture grass, but I'm not sure if I want 2'-4' of grass in the enclosure. I was thinking of a turf grass like zoysia or a bermuda grass. I just need to know if the pasture grass can be trimmed to a shorter height, and if zoysias and bermudas are as nutritious as the pasture grasses. Also a lot of the pasture grasses down here have Johnson grass included in them, that can go through a toxic period during times of drought.... anything you have to share would be appreciated.
