The answer to 'lawn fertilization maintenance tips' is to fertilize your lawn 2-3 times per year, in early spring, late spring, and early fall. This helps maintain a healthy, green lawn by providing essential nutrients. Use a slow-release, balanced fertilizer (e.g. 10-10-10 or 12-4-8) and apply it evenly across your lawn according to the product instructions.
Be sure to mow your lawn to the proper height (3-4 inches) before applying fertilizer, and water the lawn thoroughly after application. This will help the fertilizer soak into the soil and reach the grass roots. Avoid over-fertilizing, as this can damage your lawn.
