The answer to 'how to maintain lawn fertilization' is to follow a regular fertilization schedule and use the right products for your lawn. Proper lawn fertilization helps promote healthy grass growth, improves drought resistance, and prevents weed and pest problems.
For most lawns, it's recommended to fertilize 2-4 times per year - in early spring, late spring, summer, and fall. Use a balanced, slow-release fertilizer formulated for your grass type and soil conditions. Apply the fertilizer evenly across the lawn according to the product instructions, and water it in thoroughly after application. Avoid over-fertilizing, which can damage your lawn.
