You can expect to see results from 1 to 5 days after you start using thefertilizer. The best way to find out is to test your lawn to make sure it’s getting the nutrients it needs.
You can do this by taking a sample of the soil and testing it for nitrogen, phosphorus, potassium, and other nutrients. If the test shows that the lawn is getting enough nutrients, then you know that you’ve got a good lawn and you don’t need to worry about fertilizing it anymore.

Does lawn fertilizer make a difference?
Even though you probably don’t have pasture to take care of, my accidental visual test plot offers an obvious answer to a question many homeowners have. The graph below shows the amount of nitrogen (N) and phosphorus (P) that is added to the soil during the growing season. As you can see from the graph, nitrogen is the most important nutrient, followed by phosphorus and then potassium (K).
The graph also shows how much of each nutrient is lost to evaporation, so the more nitrogen you add, the less of that nutrient will be available for the plants to use. In other words, if you fertilize too much, you’re going to end up with a lot of fertilizer left over, which means you’ll have to add more fertilizer to get the same amount out of your soil.
On the other hand, adding too little fertilizer will result in less fertilizer being available to your plants, resulting in a lower crop yield. This is why it’s so important to keep your fertilizer application rates low, especially when it comes to nitrogen and phosphorous, as they are the two nutrients that make the biggest difference in crop yields.
Should I water grass after fertilizing?
We recommend that you wait 24 hours before watering your lawn. It’s important to make sure that it gets a good watering session after the 24 hour waiting period. The water helps break down thefertilizer and begin feeding it to the lawn.
How often should you water grass after fertilizing?
After fertilization, rinse the grass blades with enough water. You should resume your normal irrigation schedule of 1 to 1 1/2 inches of water per week. Fertilize in the fall and winter when the soil temperature is between 60 and 70 degrees F (16 and 18 degrees C). .
When should you not fertilize your lawn?
Don’t applyfertilizer right after a storm. If a rainstorm has soaked your lawn and saturated the soil, it’s a good idea to wait a day or two. This will allow the ground to dry out some so you don’t create runoff—and wasted fertilizer—when you water in the future.
If you’re not sure how much fertilizer to apply, check with your local county extension office. They can help you figure out the right amount of fertilizer for your area.
How long does fertilizer last on grass?
Most liquid fertilizers will only last in the soil for about one to two weeks before they have to be reapplied. You will have to use them every two to three weeks depending on the type of fertilizer you have.
Fertilizers should be applied in a well-ventilated area and should not be left in direct sunlight for more than a few minutes at a time. They should also be stored in an airtight container away from heat and moisture.
Should I mow before fertilizing?
If you have a lawn mower, you can use it to mow your lawn.
