Is it okay to cut back native grasses at this time? All different varieties?

Right now would be a fine time to mow or cut back grasses. There are two types: cool season and warm season. The cool season grasses have just started to grow and may have some new green leaves that are about three inches long or shorter. The warm season grasses will be dormant for the most part until May. As long as the material you are cutting back is the dead stems and leaves from last year, you won't have any problems. Cutting down to a height of 3-4" from the soil surface would be a pretty safe cutting height at this time of year. If you have any more questions, please feel free to contact me directly.
I hope this helps.
