7 Tips on preventing over-fertilization<\/span><\/h2>
If you don\u2019t know how to avoid over-fertilizing your lawn, you may accidentally overload the soil with nutrients and burn your grass.<\/p>
While you can still fix an over-fertilized lawn, it would be better if you could prevent it from happening in the first place. Here are some tips straight from lawn care experts:<\/p>
1. Know what your lawn needs<\/span><\/h3>
Guessing is not an option. Don\u2019t fall into the common misconception that you can simply buy any fertilizer, apply it, and your lawn will be beautiful in no time.<\/p>
Since not all lawns are the same, you\u2019ll need to test your soil to understand its specific nutrient needs<\/strong> \u2014 whether it be one of the primary macronutrients potassium, phosphorus, nitrogen, or micronutrients like calcium and magnesium. If you follow the recommendations on the soil test results<\/a>, you\u2019re less likely to over-fertilize your lawn.<\/p>
2. Fertilize at the right time<\/span><\/h3>

That said, you must not apply plant food in harsh weather conditions like extreme heat and heavy rains. Fertilizing your lawn under stressful circumstances can lead to nutrient runoff<\/a>, poor absorption, or imbalances.<\/p>
Experts recommend fertilizing when your grass is actively growing<\/a>:<\/p>
- The best time to fertilize warm-season grasses like Zoysiagrass and bermudagrass is late spring to early summer. However, you also can apply fertilizer in late summer<\/a> to early fall as needed.<\/li>
- For cool-season grasses like Kentucky bluegrass and tall fescue, the best time to fertilize is in late summer to early fall. Then, you can apply winter fertilizer<\/a> before winter and fertilize again in early to late spring.<\/li> <\/ul>
Pro tip:<\/strong> Keep a record of your fertilization schedule to monitor your fertilizer applications. Also, log information like the type of fertilizer used and the amount you applied in your record.<\/p>
3. Follow the instructions on the label<\/span><\/h3>
If you\u2019re using a commercially available fertilizer, you can find essential information on its packaging. Apart from the N-P-K (nitrogen, phosphorus, and potassium) ratio, you\u2019ll also find application instructions on the fertilizer label.<\/p>
It\u2019s good to stick to the recommendations of the fertilizer\u2019s manufacturer for the application rates and schedules. However, you also must consult the results of your soil test. This way, you can be certain that you won\u2019t over-fertilize your lawn<\/a> and cause nutrient buildup in the soil.<\/p>
4. Reduce fertilizer dosage<\/span><\/h3>

An under-fertilized lawn is easier to fix and has less damaging effects<\/strong>. You just have to add more fertilizer to correct the lack of nutrients.<\/p>
Pro tip:<\/strong> Unless you urgently need a specific nutrient to save your turf, using a slow-release fertilizer<\/a> is better. The gradual release of nutrients allows the grass to get the required nutrients without overloading the soil.<\/p>
5. Apply the right amount of fertilizer for your lawn size<\/span><\/h3>
If you don\u2019t measure the actual size of your lawn, you may overestimate its measurements and accidentally over-fertilize it. It\u2019s not uncommon for homeowners to apply more fertilizer than needed because they think their lawn is larger than it actually is.<\/p>
To avoid this mistake, don\u2019t forget to measure your lawn\u2019s square footage before applying fertilizer. Once you know the actual size of your lawn, you can now calculate the amount of fertilizer you need using this formula<\/strong>:<\/p>
Fertilizer needed = (N amount of nutrient needed in lbs. \/ 1,000 sq. ft.) * (1 lb. fertilizer \/ N percent of nutrient in fertilizer) * area to be fertilized in square feet<\/em><\/p>
For instance, your lawn is around 1,500 square feet and the recommendation in your soil test report is to apply 5 lbs. of nitrogen per 1,000 square feet. If you have a 20-0-0 fertilizer (which means there\u2019s 20% nitrogen and 0% phosphorus and 0% potassium), you\u2019ll need to apply 37.5 lbs. of this inorganic fertilizer<\/a> to your lawn. The computation is:<\/p>
Amount of fertilizer needed = (5 lbs. of nitrogen \/ 1,000 sq. ft.) * (1 lb. fertilizer \/ 0.20) * 1,500 sq. ft.<\/p>
6. Use other sources of nutrients<\/span><\/h3>

Shutterstock<\/a><\/figcaption><\/figure> You don\u2019t have to rely solely on inorganic fertilizers to provide the necessary nutrients for your lawn. In fact, you can use a combination of organic and inorganic fertilizers<\/a>. One of the most common organic fertilizers used by homeowners is grass clippings.<\/p>
After mowing your lawn, you can leave the grass clippings<\/a> and let them decompose to return nutrients to the soil naturally. Doing so can reduce the need for additional fertilizer.<\/p>
According to John Cobourn, water resource specialist, and Heidi Kratsch, landscape horticulture specialist, both from the University of Nevada Cooperative Extension, \u201cIf you recycle lawn clippings<\/a> back into the lawn, use only \u00bd pound actual nitrogen per 1,000 square feet of lawn<\/strong> for your spring fertilization.\u201d<\/p>
7. Monitor your lawn<\/span><\/h3>
Keeping an eye on your lawn doesn\u2019t mean you\u2019ll have to monitor it 24\/7. After applying the fertilizer, you only need to check your lawn once or twice a day for a week or two to ensure everything is as it should be. The following signs will confirm you\u2019ve fertilized your lawn properly<\/strong>:<\/p>
- Healthy new grass growth<\/li>
- Minimal thatch buildup<\/li>
- Better water retention<\/li>
- No signs of fertilizer burn<\/li>
- Uniform green color across the lawn<\/li> <\/ul>
But if you notice brown grass and bald patches, they are obvious signs of over-fertilization<\/a>. Additionally, over-abundant growth is another sign you might have applied too much plant food.<\/p>
FAQ about over-fertilized lawns<\/span><\/h2>
How do I fix an over-fertilized lawn?<\/span><\/h3>
To fix an over-fertilized lawn, you\u2019ll first need to check the extent of the damage to your lawn. Then, you must remove the excess fertilizer and saturate your lawn with water to leach the remaining fertilizer. If it doesn\u2019t fix the issue, you might have to replant the grass in the affected areas.<\/p>
How long will it take for my over-fertilized lawn to recover?<\/span><\/h3>
It depends on the extent of damage to your lawn, but most grasses recover after a few weeks.<\/p>
Does fertilizer burn affect the environment?<\/span><\/h3>
Yes. Apart from harming your lawn, fertilizer burn also has environmental impacts<\/a> like the emission of harmful gasses into the air and algae blooms that suck out oxygen in surface waters.<\/p>
Get help from a reliable pro<\/span><\/h2>
By following these simple steps, you can easily avoid over-fertilizing your lawn. But if you\u2019re unsure about your fertilization practices or simply don\u2019t want to worry about over-fertilization, don\u2019t hesitate to hire a local pro<\/a> for expert services.<\/p>
Also, avoid issues by letting a lawn care pro<\/a> handle other tasks like dethatching, mowing<\/a>, and aeration<\/a>.<\/p>
