When is the best time to fertilize my grass?

The best time to fertilize your lawn in North Dakota is in the fall, before colder weather starts to discolor your grass. If you only fertilize once a year, this is the time to do it.

Why is fall perfect for fertilizing?

Homeowners don’t have to deal with the heat of summer and lawns get a much-needed break from high temperatures and periods of drought. At this point, the soil can be depleted of important nutrients that help promote growth. Fertilizing now will help protect grass through the winter and encourage it to green up in the spring.

How to know when conditions are right for fall fertilization

Ideally, homeowners should fertilize when the grass has slowed its growing to a point where it’s no longer necessary to mow, but the ground has not yet frozen. In North Dakota, this could be October or November, but our unpredictable weather may keep you on your toes. Keep an eye on the forecast!

If you fertilize more than once a year…

Many homeowners do a light fertilizing again in the spring to perk up the grass after its winter dormancy. Temperatures are still mild at this point in the year and a light feeding will encourage new growth. It’s important not to overfertilize in early Spring, which can compromise root growth. If you have pets who have killed areas of grass over the winter, this is your chance to perk those sections back up!

When fertilizing in the spring, be sure to wait until the ground has thawed and has reached a temperature of about 55 degrees. You’ll recognize that when lilacs start blooming and the green color has returned to the grass.
