Applying a winter fertilizer tocool-season grassis the last step in a year-round regimen to keep your lawn looking good.
Different states have their own laws about when you’re able to and cannot fertilize your lawn.
Washington, D.C., for example, prohibits fertilizing your lawn between November 15 and March 1.

What Is Winter Fertilizer?
Fall is the prime season to feed for cool-season turf grass.
It’s a time for your lawn to strengthen its root system and store nutrients.

Heavy rainfall washes away fertilizer and runs off into water systems.
The shorter grass will help the winter fertilizer reach the the root system where it’s needed.
In choosing a synthetic winter fertilizer for your lawn, look atthe NPK ratioon the fertilizer bag.
Instead, it will contain nitrogen and potassium, which will be reflected in the NPK ratio.
A typical ratio for a winter fertilizer will be 21-0-20.
Apply winter fertilizer about 4 to 5 weeks after your earlier utility of fertilizer in the fall.
A fall utility of fertilizer before the plant goes into dormancy can support root growth.

Do you should probably Fertilize Your Lawn in Winter?
Always perform a soil test first to determine if any nutrient deficiencies exist before applying lawn fertilizer.
The lawns current condition should dictate if it needs feeding, not the calendar.
