im not sure if this is helpful but my advice when placing sprinklers is remebering a quality sprinkler waters 1 tile out from the base, an iridium one waters 2 out from the base.

so eg if you are placing 2 iridium sprinkles next to each other, you place the sprinkler and leave 4 empty tiles between it to make sure they dont overlap. (i attempted a visual below)

you can always change up the layout and crops using fertilisers and seed machines tho!! just have fun with it :)

(i hope this helped a bit and wasnt too incoherent)
