Sugar on burnt grass is an age-old remedy that always yields awesome results. Multiple things affect grass blades and cause them to burn. Burnt grass turns yellow, brown, or wispy and looks like a lost cause.

Full Details of Helping Burnt Grass with Sugar

However, this guide will tell you how to use sugar to promote the regrowth of new and healthy grass after it is burnt down.

Can Sugar On Burnt Grass Help?

Yes, sugar on burnt grass has been known to help accelerate the growth of fresh, new grass blades. Sugar feeds the beneficial microbes in the soil that convert nitrogen into a form that’s easy for the grass root to absorb. Hence, it promotes the uptake of nutrients and promotes new growth.

– Role of Sugar

Sugar itself, when added to the soil, is useless for grassroots. Plants and grasses have little to no way of taking in sugar and utilizing its energy.

Which means that to elaborate the fact of how exactly does applying sugar on sun-scorched grass help this notion has quite some aspects of so because it is a perfect binding agent due to its carbon and nitrogen content.

Role of Sugar on Burnt Grass

Sugar encourages and makes it easy for burnt grass roots to absorb nitrogen from the soil. Nitrogen is the most vital nutrient that roots need for their development, regeneration, and growth. It is also needed to form chlorophyll that the new grass blades use to make food for themselves, which is the matter of photosynthesis.

Whenever you apply nitrogen to the soil, either as a commercial formula or an organic one, it needs to be converted into a form that the roots can absorb first. Microbes in the soil carry out this conversion.

Note that these microbes love sugar and increase exponentially when you add it to the soil. You will see your burnt grass growing fresh new leaves faster than ever.

– Soil Amendment

You can even use sugar as an effective soil amendment to grow the best grass. However, one way to add it to the lawn is by using sugar water, as it is a great binding agent. As sugar is dissolved in water, it can reach deeper down in the soil and reach the growing ends of the roots where it is needed the most. 

Adding sugar has been known to promote the downward growth of the roots into a more extensive system. When sugar is part of your soil’s amendment, it makes nitrogen easily available to the plant and roots’ roots. Anything planted in such a lawn grows vigorously and much more healthily than otherwise.

Soil Amendment for Lawn Grass

Beneficial bacteria in the soil use sugar as a source of energy to convert nitrate into nitrite, which the roots need for their survival and growth.

That is why it is key to be mindful that no matter what type of soil amendment you go for, you must check their ingredients list to confirm that it contains a significant quantity of sugar.


How To Help Burnt Grass?

To help burnt grass, you must fertilize it by applying sugar, you must not mow it. In addition to these, you must also water it to help with the scorched grass, remember that composting and mulching will help the grass.

– Fertilize with Sugar

Sugar is a fertilizer that is easily applied all over lawn grass. You can use any quantity, but a more accurate estimate is one pound of sugar per 300 square feet. This is the ideal amount of sugar that works the most effectively if evenly spread all over. 

The simplest method is to take sugar in powdered or granulated form and sprinkle it over the soil as evenly as possible. Instead of sprinkling by hand, use the bucket method; otherwise, you will miss a lot of spots and end up dumping too much sugar in one spot. 

Fertilizing Soil with Sugar

First, you must take a plastic bucket and drill several pencil-sized holes at the bottom of it. Then you must fill it with the measured quantity of sugar and then walk across your lawn in straight lines holding the bucket upright.

You can later lightly spray the sugar with water, absorbing it fully into the soil. Wait to water it using too much pressure, or the sugar will get blown off.

Powdered sugar is much better as fertilizer than granulated sugar, which takes time to dissolve in the soil’s water. Technically, you can also use brown sugar, but it often clumps together and refuses to absorb into the ground. It might even form a thick layer on the surface that will prevent water from seeping into the soil.

– Don’t Mow Burnt Grass

Adding sugar is one of many ways you can help burnt and dead grass grow back up. You might be tempted to mow the grass low to get rid of the brown grass so that the new one grows back up. However, that is not such a good idea when it comes to grass that is already weak. 

Mowing Grass on the Lawn

You need to leave the affected grass as it is and allow new grass to grow unimpeded. When the new grass blades grow thick and long enough, then you can rake up the old burnt ones. 

If the long, scorched blades have begun to irritate you too much, mow it with a mower with especially sharp blades. Remember that the dull blades do not cut grass blades fully and further damage the grass.

– Proper Watering

Water is important to help absorb sugar into the soil to help with grass that has been burned. However, there is a technique for watering such grass, especially if you have applied sugar. 

First of all, only lightly sprinkle water over ground or granulated sugar. Secondly, a burnt lawn cannot be watered the same way as a healthy lawn. There will still be healthy patches of green grass here and there amidst the yellowed and brown patches. 

The sun burnt spots are better off watered early in the morning, however, when the sun hasn’t risen high and the day is still chilly. This way, the sensitive grass patches can absorb all the water they need to heal themselves and dissolve the sugar given. 

Water on Grass

Watering at noon or after that will yield no beneficial results. This is because most of the water will evaporate before the soil has had a chance to quench its thirst. Refrain from watering during the evening or the nighttime. In all probability, root rot caused by fungi will soon destroy the lawn, and that too sooner than burns ever will.

Deep watering is the key here to reviving grass that has burnt. With shallow watering, only the surface of the soil is moistened, and grass roots tend to stay in that layer instead of branching deep down.

– Include Some Compost and Mulch 

If the grass has been burned b drought or the sun, then covering the soil with a layer of compost and mulch helps a lot. This layer helps lock in moisture in the soil by not allowing it to escape into the air.

Compost itself is a magical remedy for damaged and dying grass. Compost has the ability to bring burnt grass back to life because of how enriched it is with nutrients and useful microbes.

Compost Mixed with Sugar

You can think of compost as a superfood for all grass types. Not only does it provide nutrients to the roots, but its microbes convert it into an easily absorbable form.

Mulch can be anything organic that breaks down over time. Yes, even newspaper and cardboard can be used as mulch. Just take care that only a thin layer of mulch and compost is used because you want to avoid blocking the sunlight from reaching the grass.


– How Long Does Burnt Grass Take To Grow Back Up?

Burnt grass can grow back up in as little as eight days if properly taken care of. Make sure you water the burnt patches abundantly and use sugar to accelerate the growth of new roots and leaves.

– How To Revive A Grass Burnt By Dog Urine?

To grow the grass back after it has been burnt by dog urine, you must wash that patch as soon as possible. Use a large volume of cold water to dilute the urea present in urine. Try adding one inch think new topsoil to that patch. Keep the affected area lightly moistened for the next few days until you see the grass blades turning green again.

– How To Revive Grass That Has Burnt From Fertilizer?

Water a grass that has suffered burns from overfertilizing copiously but slowly. After that, deep water that specific patch with a large volume of water daily for the next five days consecutively to flush out all the salt and chemicals from the soil. If the grass doesn’t start reverting to green after five days’ worth of watering, then your grass is dead. 


Sugar is known for breaking down thatch and other organic soil build-ups. It also selectively inhibits the growth of weeds, which helps the grass to spread and grow thicker.

Before you go, let us quickly summarize some important points regarding using sugar on burnt grass.

  • Adding sugar to burnt grass helps improve beneficial microorganisms in the soil. 
  • These microbes convert nitrites to nitrates and help new grass grow.
  • In addition, sugar can be sprinkled over the lawn and then lightly sprayed with a little water.
  • Technically you can use brown sugar just as well, but we advise always going for white table sugar.

Sprinkling sugar on grass that has suffered burns alone will not revert the grass to green again. It is a common hack that does accelerate the growth of new roots and leaves and is worth giving a shot at.
