Does My Lawn Need a Winterizer Fertilizer?

 

Many fall lawn applications have used the term “winterizer” to promote the sale of fertilizer blends from August through November. As we cold weather starts to move in, you’re probably wondering if you should be applying a late fall fertilizer as well. Now is the perfect time to do so since the ground has yet to freeze and the grass is still green. However, it’s important to understand what a winterizer is supposed to do as there are many myths surrounding these applications.

What are Winterizer Fertilizers?

Contrary to popular belief, winterizers are NOT meant to encourage fall lawn growth. That’s what early fall fertilizing is supposed to do. A late fall fertilizer helps lawns store food for winter and encourage more growth and rooting in early spring. It's crucial to your lawn’s success in the spring, but not all winterizers are created equal.

It was once believed that winterizers should be low in nitrogen and high in potassium and phosphorous, but this is no longer the case. Research has shown that winterizers should contain mostly nitrogen. When choosing a late fall fertilizer, make sure you look for blends that are made mostly from nitrogen. Also look for labels that say that most of the nitrogen is quick releasing rather than slow releasing.

When Should They Be Applied?

The best time to apply a winterizer is after the grass stops growing in late fall, or right around the time you put your mower away for the year. The grass should be green on top and active below the surface, which is usually around this point in mid-November. You can usually use less fertilizer than what the label says because you don’t want unabsorbed nitrogen to leach into the groundwater.

What Products are Recommended?

We recommend using Pro-Start 5-3-4 from North Country Organics. It’s a natural, non-burning, eco-compatible starter fertilizer that also makes a good choice for a winterizer. This is because it builds a thick and invasive root system that lasts through the winter and helps the grass come up thick and lush in the spring. This fertilizer blend also increases the lawn's feeding efficiency.

It’s hard to believe that nearly all the warm weather is behind us, at least for now. It’s time to put away the mowers, prune the trees and apply winterizer fertilizer. Remember that what you do today will affect your lawn in the spring, so it pays to take those extra steps this Fall!
