The answer to 'when to lawn care' is that the best time for lawn care tasks depends on the season and your specific climate. In general, spring and fall are the prime seasons for lawn care, with different maintenance tasks recommended for each.
In the spring, it's important to start your lawn care routine early, typically in March or April. This is when you should focus on tasks like aerating the soil, overseeding bare or thin areas, and applying a pre-emergent herbicide to prevent crabgrass and other weeds from taking over. Regular mowing, edging, and fertilizing should also be part of your spring lawn care regimen.
