 When To Apply Winterizer Fertilizer?

When the grass stops growing in the fall, but the winterizing is still active in the root system, apply it. The vivid green tint of your grass indicates that it is still alive.

Your exact location will depend on when this occurs, although it is normally in the middle to late November. It may even be early December on rare occasions.

The calendar below provides a visual picture of when to apply a winterized and other key lawn maintenance duties.

How To Fertilize Your Lawn In The Winter

Although you should read the directions that came with your winterized, the following are some general ideas to help you get the most out of it.

  • To guarantee consistent covering, use a fertilizer spreader.
  • It’s usually a good idea to use a bit less than the label recommends, as this decreases the risk of any nitrogen that hasn’t been absorbed seeping into groundwater.
  • See this guide for an in-depth look at fertilizer spreaders and how to use them.

The Best Fertilizer for Winterization

When it comes to selecting the best-winterized fertilizer, personal preference is key; however, Espoma EOFW30 Fall Winterizer has always performed admirably for me.

I get regular results and my grass stays nice and healthy all year, regardless of the weather (even when the nights are below freezing).

Warm-Season Grasses’ Best Winter Fertilizer Warm-season grasses are unique in that root growth continues while the blades are dormant. Much of this is due to the fact that in the winter, soil temperatures are warmer than air temperatures. 

The active root systems, which require potassium, benefit from winter lawn fertilizer. Temperature, drought, and disease tolerance are all improved by fertilizing root systems properly.

Choose a winter lawn fertilizer with a high potassium content for warm-season lawns. The last number in the N-P-K fertilizer formula is this. Fertilizers with a lot of nitrogen should be avoided. Nitrogen promotes blade growth, which isn’t required during the winter months.

Andersons 5-5-25 with Barricade is our winter lawn fertilizer recommendation for warm-season lawns. It has a good amount of potassium as well as a winter preemergent. This treatment protects your grass from winter weeds while also keeping it healthy.

Per 1,000 square feet of lawn, apply 8.1 pounds of Andersons 5-5-25 with Barricade. The optimal time is when the soil temperature reaches 70 degrees. Late autumn to early winter is a better rule of thumb. If there isn’t enough rain, don’t forget to irrigate your lawn.


A winter lawn fertilizer is meant to increase your grass’s resistance to harsh weather. It aids in the establishment of a strong root system and prepares the turf for spring.

However, just because something works for someone else doesn’t mean it will work for you. You must take into account the parameters listed above, as well as determine the sort of soil you have.

Your property’s aesthetic value will be enhanced by a healthy and green lawn with softer, thicker, and greener grass. The rest of the neighborhood will be envious of your lawn.
