Frequently Asked Questions
Should I fertilize my Zoysia grass after the first frost?
No, you should avoid fertilizing once the ground begins to freeze. By that point, the grass has entered dormancy and will not be able to absorb the nutrients you provide. Applying fertilizer too late can actually waste money and encourage unwanted weed growth during the early spring.
How much fertilizer do I actually need to apply?
Follow the application rates printed on the bag exactly, as these are calculated for optimal coverage. Most professional recommendations suggest about 0.5 to 1 pound of nitrogen per 1,000 square feet for a fall feeding. Using more than the recommended amount will not make your lawn grow faster and might burn the roots.
Can I combine weed control with my fall fertilizer?
Yes, many homeowners use a weed and feed product in the autumn to target persistent invaders. However, ensure that the herbicide in the mixture is safe for Zoysia grass, as some broadleaf killers can cause damage if the grass is already stressed. Applying a pre-emergent herbicide in the fall is also a smart way to stop winter weeds before they sprout.
How long before winter should I apply the final treatment?
Aim to apply your fertilizer about four to six weeks before the average date of the first frost in your area. This gives the roots enough time to take up the potassium and store it for the winter months. This timing acts like a nutritional insurance policy for your lawn.
Will fall fertilization help my lawn green up faster in the spring?
Absolutely, because a well-fed root system is a healthy root system. When the grass wakes up in the spring, it will have a stored reserve of energy waiting to be used. You will notice a thicker, greener lawn much earlier than you would if you had skipped the fall feeding.
