A winter fertilizer application is considered to be the second most important, or sometimes the most important treatment for the lawn. This application is done in late fall, typically Late October through early December. A winter fertilizer should be a mix of slow release and fast release nitrogen. A fast release fertilizer will help to build carbohydrates into the lawn now to promote repair work on summer damage, while a slow release will continue to assist the lawn throughout winter. Winter fertilization will also promote a quicker green up in spring.
As the weather gets colder, the lawn goes into a protective mode against the temperatures, frost and frozen precipitation so the blades grow slower, turn brown and get a little hardier as it prepare for dormancy. Under the soil, it is a different story. The root system keeps growing and becomes thicker, stronger, and deeper into the soil. The better the root system, the better the chances it will withstand drought, stress and disease during next years summer months.
A winter fertilizer assists and strengthens the continuously growing root system. The lawn will try to repair itself from damage done during the summer during the fall. Drought, heat and disease take quite a toll on the lawn and cause serious damage, so it is important to get extra carbohydrates to the root system. Carbohydrates help protect the lawn from damage and disease that can be done in the winter months.
Sum it up
To sum it up, a winter fertilizer is one of the most important things you can do for your lawn. Whether it is to help rebuild after a long hot summer or just to prepare for a quicker green up in the spring, carbohydrate building winter fertilization is the answer.
It is always a good idea to consult with a lawn care professional and ask any questions you may have. Look around, ask friends or family, and research companies on the Better Business Bureau to find a company that you can trust.
