Sure, you are tired of mowing and watering grass. Come next spring, however, you will be glad you spent a little time the next three months renovating or establishing that cool-season fescue. If you wait until spring to do your seeding and fertilizing, those tender new grass roots will gasp for life when they have to face our heat and humidity. Remember, fertilizer is not plant food, even though we often call it just that.
Plants make their own food, using water, carbon dioxide and energy from the sun.
Instead, fertilizers feed the soil so it can provide more and better nutrients for plants to absorb. Plants need 16 elements for growth. Secondary macronutrients include magnesium, calcium and sulfur. Micronutrients needed in minute quantities include iron, boron, manganese, copper, zinc, molybdenum and chlorine. Urea is a synthetic organic fertilizer.
