How Winter Fertilizer Keeps Lawns Green and Healthy During Winter Months

As a turf manager, you know that your customers want a healthy, verdant lawn even through cold winter months. Plus, winter fertilizer, called winterizer, adds potassium to protect turfgrass at the cellular level.

That’s why you need ProScape 25-0-5 51% MESA 1% Fe to put down on your clients’ lawns.

8 Benefits for Using Winterizer Two Times in the Fall

When should you fertilize fall lawns?

Ideally, you should apply ProScape 25-0-5 51% MESA 1% Fe from the end of August to the beginning of September. You use the second application toward the end of fall, starting in mid-to-late October. The second application of winterizer hardens turf cells and concentrates on the turfgrass’s root system.

The winter fertilizer is the best fertilizer to put down all season and can be the only fertilizer you use all season long.

Here are eight benefits for using a winterizer in the fall:

  1. It helps the root system to develop deep into the soil. These deep roots grow root hairs that go deep enough in the ground to find hidden moisture stores.
  2. If some of your customers only fertilize once a year, it should be in the fall with a winter fertilizer because it promotes a deep green color that lasts through the winter. It also encourages early green-up in the spring.
  3. Every year, cool season turfgrass gets most of its nutrients during autumn, making winter fertilizer essential for turf’s development and longevity.
  4. The potassium in winter fertilizer hardens turfgrass’s outer cell walls to protect them from bursting due to freezing temperatures.
  5. Use winter fertilizer only on cool season grasses. Lawn care experts recommend that you plant a cover crop, such as annual ryegrass, on warm season lawns.
  6. Cool season grasses prefer temperatures between 65ºF to 75ºF. And cool season grasses remain green well into December. This type of turf will turn brown when temperatures drop to freezing temperatures.
  7. A hot, dry summer depletes cool season turfgrass. Cool season lawns need to recover from summer stress and time to prepare for the upcoming winter. 
  8. Also, you apply 75% of cool season grass’s annual nitrogen in the fall. Turf will uptake and store that nitrogen well into the winter and use it when soil temperatures drop into the mid-30’s.
