When should I stop watering my lawn for winter?
You should generally keep watering your lawn until a genuine cold snap arrives, though you can dial back the frequency to about once a week as seasonal temperatures drop. Continuing to water too long or stopping prematurely during unusually warm autumn weather makes it difficult to judge the grass's actual dormancy needs, leading to guesswork about moisture levels.
