The leaves are falling, the cider is flowing, and you’ve officially embraced sweater season. With that crisp autumn chill in the air, you’ve also probably started to dread the freezing temps and harsh winter ahead. During the late fall season in Central Indiana, the weather and timing is just right for root development. Fall fertilization treatment, also referred to as winterization or winterizer, is imperative to preventing seasonal root damage and keeping your lawn pristine come spring.
But is it really that important? We get asked this and a lot of other questions about turf treatment this time of year. Take a look at our answers below:
Why should I fertilize my lawn in the fall?
Just because you may be mowing your lawn less doesn’t mean the plant is dead or dormant. While your grass is not actively growing on top right now, it is growing beneath the surface. Like an animal headed into hibernation, your lawn’s root cells are thickening and storing carbohydrates for the winter. Therefore, it’s imperative to feed your lawn one last time before the damaging frost and snow hits.
Why is a late fall application so important?
Put simply, this final application will provide the protection your lawn needs during the long winter and a quicker green-up in the spring. You see, roots are the backbone of the lawn. Late fall weather provides these roots with the absolute best opportunity for growth. Applying nitrogen fertilizer now encourages a healthier and deeper root system going into the next season, and helps with color upkeep during the fall and winter. It also reduces the chances of drought damage because deeper roots allow access to more water. Late fall lawn prep also helps grass get through a harsh winter and prevents overwintering damage by hardening the plant. Plus, any seeding applied now has a much lesser risk of dying from colder temperatures.
What is winterizer?
Winterizer is simply another term that’s used to describe late fall fertilizer applications. Late fall lawn treatments are often referred to as a winterizer application in the lawn care industry because it’s usually applied in late October and November. The treatment encourages roots to store more food for winter survival.
What would happen if I skipped my late fall treatment?
Proper fall lawn care leads to a thicker, greener lawn with less weeds in the spring. Without a late fall application, your lawn might not develop a stronger, denser root system to help it look lush, healthy, and vibrant when the warmer months return. Taking action now means you’re making a solid investment in a beautiful spring landscape.
Can you fertilize a lawn with leaves on the ground?
We can fertilize the lawn with leaves on the ground. However, if the leaves are so matted on the ground that no grass blades are showing, you’ll want to remove the leaf cover. Not doing so not only affects fertilizing efforts, but it can block oxygen from reaching your roots and lead to snow mold problems in the winter. With that said, even if you aren’t planning on the late fall application, make sure to keep up with regular leaf removal!
When should I mow my lawn for the last time this year?
Now is the perfect time to start planning your final mow. You’ll want your grass to be short by the time the first frost hits. Getting to that lower-than-usual height should be gradual to reduce stress on the plant, so begin the process by lowering your mower blade by 1/3” each time you mow until you reach a well-cropped height (but not below 2.5 inches).
What else should I do for my lawn during the fall?
Raking leaves, treating weeds — there are a few more things to keep in mind this time of year. Read here for the short list of lawn care to-do’s to tackle before winter hits. (Hint: We can help with a lot these, so if you’re feeling overwhelmed, just give us a call!)
