Spring is the perfect time to mow, fertilize and scarify the lawn. Scarifying should be done before fertilizing and mowing, as it loosens up the lawn and improves nutrient absorption.
The best time for dethatching is usually in spring or fall when the grass is actively growing and temperatures are not too extreme. Fertilizing helps keep the grass healthy and strong. It is best to use a lawn fertilizer with a balanced ratio of nitrogen, phosphorus and potassium.
