  • Fertilizer that contains weed killer is normally called "weed and feed." Some contain herbicides that kill weeds that have already begun to grow, called a post-emergent, while others contain a pre-emergent, which prevents the growth of weeds. It is good to get a fertilizer with a combination of both.

    Fertilizer Basics

    Your lawn needs three basic nutrients: nitrogen, phosphates and potash. Nitrogen keeps your lawn a healthy shade of green and allows for new growth. It is one of the most important nutrients that your lawn needs. Phosphates help build the root system, and potash helps your lawn resist disease.

    Cool Season Grass

    Cool season grass tends to remain green throughout the winter. If your grass is cool season grass, you will need to fertilize in the fall and early spring. Fertilize heavily in the fall before the weather becomes too cold, making sure that the effectiveness of the fertilizer has subsided before the weather becomes too severe. Fertilize in early spring, but again, be sure the fertilizer has lost is efficacy well before any severe hot weather comes.

    Warm Season Grass

    Warm season grass has the tendency to brown after the very first frost. You will want to fertilize your lawn after the grass has begun to turn green again, usually in the late spring. Be sure to fertilize well in advance of any severe hot weather, giving time for the fertilizer to have lost its efficacy before then. Fertilize once again after the summer heat has passed.

    Healthy Lawn Tips

    Feeding, watering, and regular mowing are three of the best things you can do to your lawn. When weeds grow and flower, they produce seed, so it is important to mow regularly to prevent this growth. Fertilize before it rains and while the grass is dry, or fertilize and use a water sprinkler to water your lawn. Keep grass cut between four to six inches to keep the roots cool and moist. Never apply more fertilizer than the package directs, as too much fertilizer can burn your lawn. If you spill the fertilizer, sweep or rake it up as quickly as possible and water down the area to dilute.
