Lawn Fertilizers Provide Seasonal Care

We change our diets according to the climate, often switching from an abundance of fresh fruit, vegetables, salads and grilled meat to the heartier fare that comes with cold weather. Your lawn needs different nutrients throughout the year, too. Examining some of the more common lawn care products and how they work can help you set up a lawn care and feeding schedule that keeps your lawn healthy and green.

Above Ground and Underground: Keeping Your Lawn Healthy

Commercial fertilizers are commonly labeled with the letters N, P, and K. These stand for Nitrogen, Phosphorous, and Potassium. (K originates from kalium, which is another name for potassium.) Each of these ingredients nourishes plants and grass in different ways. Nitrogen promotes above ground growth including leaves and stems. Nitrogen promotes the "show" in "show and grow." Nitrogen is what produces rapid and lush growth.

Phosphorous nourishes roots, and helps establish sturdy root systems. This helps plants fend off invasive pests such as weeds, subterranean insects, and fungi. It also helps the flow of water and nutrients to reach all parts of each plant. Winterizing fertilizers typically contain more phosphorous than nitrogen, as grass slows or stops growing during winter.

Potassium, or potash, contributes to healthy root systems and also promotes durability. Plants under stress from extreme climates can benefit from extra potassium, but potassium can cause "burn" if too much is applied to your lawn. Consult your local home and garden shops for fertilizer products best suited to your type of grass and regional climate conditions. Please remember to read all product labeling carefully before using lawn care products.
