The Proportions of the Grass Fertilizer

Winterizing fertilizer such as the ScottsGuard has variations in high levels of potassium and a little lower levels of nitrogen. This proportion is different from turf-building fertilizers used during early seasons such as warmer weather conditions.

If you look closely at the contents of the Scottsguard bag then you will notice some numbers. Let’s understand what they mean!

The Scotts WinterGuard is a 32-0-10 product meaning that it contains:

  • 32 percent Nitrogen
  • 0 percent Phosphorus
  • 10 percent Potassium
The Proportions of the Grass Fertilizer


During the winter-long season, plants may have difficulty resisting the cold. This nutrient helps them to handle the extreme chilling conditions and stress caused by sudden weather changes.

Also, potassium supports nutrient absorption and reinforces the plant at a cellular level from the root to the tip of the leaf blades resulting in a healthy-looking lawn.


Growth slows down during the winter months and this is very alarming. The plant could go into a dormant state and if not provided with food, it will die!

Nitrogen helps to prevent this by promoting leaf growth in cold temperatures. The fast green-up color and thick lush coat of grass are all due to this specific nutrient.


This nutrient is like a catalyst for the other two. The right amount will boost the performance and help in the healthy growth of the roots and other parts of the plant.
