Timing: Apply fall lawn fertilizer once between August and November, right before winter hits, 6 to 8 weeks after the summer feeding.
Best Fall Lawn Fertilizer
While this fall lawn fertilizer dose is important, an application at the end of October or early November is essential. At that time, apply a fertilizer with a formula of 13-25-12. The push of phosphorus will stimulate root growth through November and even into early December.
In general, try your best to apply it between September 1 and October 15. The farther north you live, the earlier you should apply it. The goal is to have at least one month of active grass growing weather remaining before winter takes its grip.
You should fertilize your lawn a day or so after a light rain or using a sprinkler. This prevents the application from being washed away. The moisture gets your soil damp and ready to receive nutrients. Do not apply fertilizer before or after heavy rains.
Fall Fertilizer Timing
For the majority of cool-season lawn owners, apply fertilizer anywhere from September through early November. The further north you garden, the sooner you'll feed your lawn. Fine-tune the timing for your locale by talking with your local extension service or garden center.
Ideally, you'll want to mow and rake before fertilizing, so that excess lawn waste is removed and the fertilizer will have an easier time reaching the soil.
Watering after fertilizing washes the fertilizer off of the grass blades and into the soil, where it can get to work nourishing your lawn. It's also important because if fertilizer sits too long without being watered in, it can burn the grass.
The composition of a fall fertilizer is a bit different than its winter counterpart. While both fertilizers contain potassium, winterizers usually contain a higher amount of this mineral to sustain your grass when the ground freezes.
We recommend waiting 24 hours after fertilizing to water your lawn, which will give the fertilizer time to settle. After the 24 hours are up, it's important to give it a good soak—not just a quick spritz with your hose—to activate the fertilizer and help the critical nutrients absorb into the soil.
Can I put too much fertilizer on my lawn? There is the idea of “too much of a good thing,” and that definitely applies when it comes to fertilizing your lawn!

The November fertilizer application is the second most important time for cultivating a cool season bluegrass or tall fescue lawn, with September being the most important application. The November application helps the lawn flourish in several ways.
The theory behind late fall nitrogen fertilization of cool season grasses is very simple. Apply low rates of N fertilizer (40 to 50 lbs/acre) in the late fall (mid October to late November) when cool temperatures have reduced top growth, but root growth is still active.
Don't fertilize during a drought.
Most fertilizers need a thorough watering or two to soak into the soil, and allowing the fertilizer to sit on top of the lawn without watering it in could burn the grass. You may want to delay the application until wet weather arrives.
While the best method for determining exactly how much fertilizer is needed is a soil analysis conducted by a laboratory, most cool-season grasses require 2 to 4 pounds of nitrogen per 1,000 square feet each year, and a majority of this nitrogen should be applied in two fall applications; one in September and the other ...

All fertilizer labels have three bold numbers. The first number is the amount of nitrogen (N), the second number is the amount of phosphate (P2O5) and the third number is the amount of potash (K2O). These three numbers represent the primary nutrients (nitrogen(N) - phosphorus(P) - potassium(K)).
Although some fertilizers benefit from slightly moist grass, if your lawn is too wet, it will fail to properly absorb the nutrients. This includes both granular and liquid fertilizer products. You should avoid applying foliar fertilizer to wet grass because it could lead to nutrient burn.
If fast results are desired, lightly water the product in after application; however, watering-in is not required.
At Master Lawn, we typically say to wait 24 hours before watering your lawn after fertilizing. But it is important to make sure that it does receive a good watering session soon after that 24 hour waiting period.

The short answer is “yes,” but only if is of a certain type. Granular and liquid fertilizers and those containing post-emergent herbicides must only be applied to wet grass. In contrast, foliar fertilizers and those that contain pre-emergent herbicides and should not be applied to wet grass.
