Fertilizers are generally applied in the early spring, just before the growing season begins, and again in the fall, after the growing season has ended. Some plants and trees require mid-season applications; in these cases fertilizer should be added during the midsummer months. Lawns require feeding approximately every 45 to 60 days from spring through fall.
