Fall Fertilizing for Cool Season Grasses: Fall Fertilizer Lawn Care


Date: October 1st, 2014


While it may seem like an odd time to fertilize your lawn, fall fertilizing is a crucial last step in lawn care programs. Fall fertilizing will strengthen your lawn's roots and give them a strong support system for the following seasons.

The guide below is for cool season grasses. How do you know what grass type you have? Check out the map to the right.

A large section of the U.S. is classified as having transitional grasses. This means that both warm and cool seasonal grasses may grow in the area. If you live in the transitional area, a clue to which type of grass you may have will occur after the first frost. If your lawn turns brown after the first frost, then your lawn is most likely a warm season grass.

When do I fertilize?

The exact date will vary due to weather temperatures, but the final fertilizer application should be made when the grass stops growing but before the ground freezes. Typically this is in the months of October and November. Proper timing is essential – if applied too early when the grass is still growing, your lawn can become susceptible to disease and injury from winter weather and snow mold.

Which fertilizer?

Before applying a fertilizer, the first step is to understand the 3 number formula on the package. For example, 5-10-5 is a very common fertilizer. The first number in the sequence represents nitrogen; nitrogen promotes lawn blade and foliage growth. The second number stands for phosphorous, which helps root growth, and the third number is for potassium, which promotes cell function and the absorption of trace elements. But which is best for the fall?

In September or October, grass is recovering from a long hot summer and may be coming out of a drought-induced dormancy. Giving your lawn a fertilizer rich in nitrogen will promote blade growth. Turf Line Winterizer Fall Fertilizer is specially formulated for fall use and has an 18-0-12 formula.

This and other winterizer fertilizers are specially formulated with higher potassium than regular lawn food to makes grasses more winter hardy.

How do I apply the fertilizer?


Fertilizer comes in two forms: granular and liquid form. Granule fertilizer should be spread with a broadcast spreader. Set the rate-of-flow lever according to the fertilizer bag. Pay close attention to the instructions on the bag. If you are unsure, it is better to apply too little rather than too much.


Control Lawn Disease, Weeds and Insects


Leaf piles may be fun to jump in, but leaves left on the lawn encourage lawn disease by preventing sunlight and fresh air from reaching the grass. Use a rake or blower to collect them and add them to a compost pile. Or, prepare them for mulch.

For weed control during the winter months, apply a pre-emergent weed killer.
