We recently posted about getting your lawn ready for the cold weather season and included information to ensure your lawn will have a good chance of surviving the upcoming winter. Applying a late season fertilizer was included as an important measure to take, as timing is critical.
For instance, fertilizer that is applied too early on in the season will promote succulent growth during the fall season, which can affect the health of your lawn heading into winter temperatures. A late-fall fertilizer application replaces the need for a spring fertilization and will allow you to delay it until late May or early June. Here are some of the principles of late-season fertilization to apply to your lawn.
According to Ontario’s Ministry of Agriculture, Food and Rural affairs, these are the principles of late-season fertilization:
- Roots remain active at cooler temperatures because of nitrogen.
- Nitrogen enhances fall colours and increases chlorophyll content.
- An increase in chlorophyll content means an increased production of photosynthesis
- Increased photosynthesis is a sign of increased sugars in the turf. These sugars are not used for growth (at the time you fertilize) but rather are stored for winter survival and growth recovery in spring
- Increased sugars make the grass plant less susceptible to damage from freezing temperatures.
- Late-season nitrogen applications promote deep rooting during the fall so during spring and summer they re-develop healthier roots.
- Your lawn will return to a green much earlier because the nitrogen stored in the roots is ready when grass shoots resume growth.
