Doesn’t matter, mowing often will make the problem worse regardless of what’s being mowed. Plus, there are tons of local fauna that will use grass to hide, live and grow during the time you’ll be not mowing.

Would it be better to plant native grasses? Absolutely. But we should still encourage whatever biodiversity we can to help our local area. Every little bit helps, because it’s not just the grass that you’re helping by leaving it to grow.
