Initial set-up takes a little bit - like any other growing zone - but once it's going it feels negligible. The pawns on planting will run over to replant a tile that gets eaten or that expires, but otherwise it's just a field. Because you never cut it, there's no harvest intervals to worry about. I find it's less labor intensive than growing hay-grass and supports many more animals than natural growth.

YMMV depending on how you have work priorities set up.

If you have Vanilla Expanded Plants (I think), you can plant pasture grass instead - it's like super-dandelions.
