Watering: Dilute the excess fertilizer by watering your lawn daily for a week. Ensure you saturate the grass with at least an inch of water. Delay Mowing: Let your grass grow a bit longer than usual. This allows for more photosynthesis, helping the grass absorb the excess nutrients.
To repair grass that has been burnt by fertilizer, first, thoroughly water the affected area to flush out excess salts. Wait for a few weeks to see if the grass begins to recover naturally. If damage persists, consider overseeding the area with appropriate grass seed, and keep it consistently moist.
Watering. Giving your lawn extra water helps to dilute and wash away the excess fertilizer. This remedy works best if done promptly after over-fertilizing but even if you already notice some browning or yellowing of the grass, water helps it to recover and bounce back.

If you've overdone it with the fertilizer, you may still be able to save your lawn. Burned lawns will need a generous amount of water to get back to green. It's vital that you water the lawn as soon as you spot any brown or yellow patches to prevent further damage.
Recognizing Over-Fertilization Lawn Symptoms
If you've accidentally spilled a bag of fertilizer before, you probably already know what fertilizer burn looks like. It shows up as scorched areas of the lawn (literally looked “burned”) and is typically crispy and yellow (or brown).
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.
The goal is to flush out all the excess salt from your lawn and leach the fertilizer from the soil and root zone. You'll need to water your lawn until the soil can't soak anymore. That means at least an inch of water daily for a week or two. Remember to do it even in areas where the grass seems healthy.
When you apply too much fertilizer to your lawn, the excess salts seep into the soil, surround the root system, and prevent proper water absorption. Once your grass is affected at the root level, it loses its health, vitality, and vibrant color, leaving you with dead brown patches.
While spreading fertilizer during light rain is generally acceptable, heavy rainfall can wash away the nutrients before they have a chance to soak into the soil. It's crucial to pay attention to the weather forecast and ensure only light rain is expected.
Symptoms and Signs of Over-Fertilization
Yellowing and wilting of lower leaves. Browning leaf tips and margins. Browned or blackened limp roots. Defoliation.
If possible, apply organic matter and/or a microbial inoculant such as compost tea or effective microorganisms (EM). Perhaps the microbes will do something with the excess, tying it up in their bodies or even biologically transmuting it into something else.
Too much fertilizer adds too much nitrogen and salt to the soil. It's called fertilizer “burn,” and can actually kill your lawn. Imagine the yellow or brown dog urine spots you see in lawns.
If the dried, burnt areas are limited to small bare patches in the lawn, then you may be able to encourage growth there by watering them generously and fertilizing those areas. However, be aware that fertilizing grass during hot weather can make grass less tolerant to heat.
In lawns, fertilizer burn may show up as scorched stripes where trips across the lawn overlapped too much, or it may involve the entire lawn or spots where fertilizer spilled. In garden plants, it often appears as brown, burnt-looking tissue on leaf edges and tips.
Over-fertilizing can cause what is known as a salt build-up which in turn causes the grass to 'burn. ' The result is brown, yellow, or streaked patches that are dry and unattractive. Over application can be just as harmful as under application and can have unsightly results.

For brown or yellowing grass, proper irrigation and soil enrichment are key. Rake dead spots, plant new grass seed, water regularly, and use high-phosphorus fertilizer to encourage healthy growth.
It can return to its initial green and lush look in a few weeks, or it can take months. It's a game of patience, and the timeline depends on the grass type, damage level, weather, soil conditions, and lawn care practices.
Prune all of the dead foliage off of your affected plants. If you're treating burned grass, reseed the area with new grass seeds over the damaged brown grass. You'll have to wait to see if the affected areas can recover, but pruning damaged growth away is a good start.
We know fertilizer is an easy way of making sure your lawn is healthy and green, but if you start to apply a little too much, you can dry your soil out completely. Over-fertilization will turn the grass yellow or brown, or even kill it completely!
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. Watering helps the fertilizer to activate and to break down and begin feeding nutrients to the lawn.
Magic Carpet is a strong slow-release fertilizer. It is not diluted, but it is a slow-release nature prevents it from burning your lawn. The strong commercial grade wax coating (XCU= 65%) on the granules allows it to break down slowly over time, usually taking 6-8 weeks to completely dissolve.
Most granular fertilizers dissolve within 24 to 48 hours, though the formula and brand may impact the overall dissolve time. Read through the packaging to get a better idea of how you should apply the fertilizer and how long you should wait to mow to ensure it dissolves properly.
If you're watering and fertilising properly but your lawn is still brown or patchy there may be other problems. One of the main causes of lawn not responding to fertiliser is the pH level or your soil being too high or too low.
