currently grass only spreads when it is recently planted. this is good, because it allows you to make cool patterns with grass. however it also makes grass farming incredibly difficult. in order to “split” grass seeds one must continually dig up grass and replant it, and the spread rate is so slow that it takes a huge ammount of time and shovel durability to get even 1 new grass seed. basicly i want the spread rate on grass seeds to be higher. and before you ask, yes ive tried it with and without fertilizing, its about the same.
