The answer to 'lawn fertilization maintenance tips' is to fertilize your lawn 2-3 times per year, in early spring, late spring, and late fall. This helps promote healthy grass growth, improves soil quality, and prevents weeds. Use a balanced, slow-release fertilizer and apply it according to the manufacturer's instructions. Be sure to water the lawn thoroughly after applying fertilizer to help it absorb into the soil.
It's also important to mow your lawn regularly, leaving the clippings on the grass to act as a natural fertilizer. Aerate your lawn once a year to improve air and water flow to the roots. If you notice any bare or patchy areas, overseed those sections to fill them in.
