There’s no specific timeline for mowing the lawn as there are a number of factors that determine the frequency with which you should do so. These include your local climate and how long it takes your grass to grow. Hot and dry climates slow down grass growth significantly, so you won’t have to cut your grass as frequently as you would in cool climates. Overgrown hedges should be trimmed or pruned back sometime during late winter or early spring because that’s when they’re still dormant and the risk of damaging the plants is lowest.
