Direct answer
Use Sprinklers after your crop plots are close enough together and your base has enough power to support automated watering. Place the Sprinkler near the middle of a compact field, then check the outer plots for any dry corners.
Best place to put a Sprinkler
Because Sprinkler coverage can miss corner plots, the practical rule is:
start with a compact farm, place the Sprinkler centrally, then confirm each outer crop plot is actually watered.
Avoid building a large square field first and assuming one Sprinkler will cover every corner. Several players report that wide layouts can leave edge or corner plots dry.
Power and rain checks
Sprinklers are part of the larger farming automation loop, so do not treat them as only a crop-placement problem.
Before expanding a sprinkler field, check:
- whether your power grid stays stable overnight
- whether batteries can cover cloudy or rainy periods
- whether a switch or later control setup can stop watering when it is not needed
- whether your Greenhouse plan changes how rain affects the farm
If your grid is already strained by drills, powered buildings, or other automation, add power stability before adding more Sprinklers.
Sprinkler not watering: quick checks
If crops are still dry:
- move plots closer together
- rotate or reposition the Sprinkler and check the corner plots again
- confirm the Sprinkler has power
- avoid assuming rain will solve every watering gap
- protect key crops with a Greenhouse when storms become the bigger risk
A good farm layout should make watering easier, not leave you manually fixing the same corner plots every day.
