It's easy - Apply ClayMend with a Hose End Applicator

You simply apply ClayMend to your lawn and/or garden. Use a hose end applicator designed for liquids.

Water ClayMend Into the Soil After Applying

After you have applied ClayMend, water the lawn for a few minutes to wash it into the soil. ClayMend can be applied where plants are growing, and although it will not harm your plants it is best to wash it off of the plants into the soil where the benefits can occur.

Repeating Applications Can be Beneficial

Repeating applications of ClayMend can result in accumulated improvements to your clay soil, especially during the first year you use ClayMend. You can repeat applications every 4 to 6 weeks if desired.

Application Instructions

Unlike other liquid fertilizers and amendments that give you a dilution amount or setting on a sprayer, ClayMend is applied based on the size of the area you would like to treat. Many hose end applicators come with general instructions for applying other fertilizers. Disregard the instructions that come with the sprayer when applying ClayMend.

Video begins before ClayMend was applied, shows ClayMend being applied and worked into soil then returning a year later to show change over one year. Note that ClayMend was applied two or three more times during the first year and simply watered into the garden.

Some clay soils rely mostly on the biological activity in the process of restructuring the soil but other clay soils, such as those shown in the videos, break up right before your eyes. Remember that the microscopic organisms do take time to physically move the soil around and restructure it so that it is more porous.

Follow the Steps Below

Before You Get Started

First, you will need a hose end applicator designed to measure and apply liquids. Spray applicators that are designed to dissolve powders (like Miracle Gro) will not evenly distribute liquids.

Applicators that are designed for liquids are available at many of the big box hardware stores, many local hardware stores and many nurseries. You can also order online from internet retailers such as

Application in Three Easy Steps

Measured Product

Pour Product Into Applicator Bottle

Spray Onto Measured Area

First determine the area you need to treat. Then simply reference the recommended application amount listed on the product label. All our recommended application amounts are stated in ounces of product per 100 sq. ft. of treatment area. You can use a measuring cup or use an applicator bottle that has measurements marked on it.

Use your hose end applicator bottle to measure the product or pour the measured amount of product from your measuring cup into your hose end applicator bottle. Only use a hose end sprayer designed for liquids. Applicators designed to dissolve powders will not provide an even application with our products. The liquid applicators apply the product at a constant rate and the bottle will empty as you apply it.

Spray evenly over the measured area until applicator bottle is empty. Some hose end sprayers have an adjustable dial for dilution. Set the dial to 1 oz. and spray evenly over the area until the hose end bottle is empty. Keep an eye on the amount left in the bottle as you spray to make sure you are applying the product evenly. To get an idea of how fast to walk you can fill the applicator with water and see how fast it empties as you walk.

How to determine the square footage of your lawn

Get an approximate measurement of the area to be treated. An easy way to approximate the square footage is to pace off the yard. One walking step of an adult is generally considered to be approximately 3 feet. Pace off the length of the area and then the width of the area that you would like to amend. Most yards have strange curves and separate areas, we just need an estimate so pace to the furthest point. Multiplying the number of paces by 3 will give you total length and width in feet. Multiplying the width in feet times the length in feet will give you the total sq. footage. (L x W = total sq. ft.) This will be a rough approximation but adequate for our products.

Pour enough water into the applicator to fill it

For most application we generally fill the remainder of the bottle to increase the volume enough to cover the measured area. The water is only to increase the volume enough to get the product evenly distributed over the area. If you are only applying a few ounces of product it can be hard to get the sprayer to siphon out that small an amount without adding water for volume. The instructions for many hose end sprayers will say not to add water at this point. This is one of the areas that we deviate from their instructions. Because we measure based on square footage instead of dilution the amount of water is not important.

Turn on your sprinklers after applying the product

Spray area with water or turn sprinklers on for a few minutes to wash product into the soil. All of our products can be sprayed directly on lawns, on and around garden plants, on or around shrubs and trees or directly on bare soil. When applying to areas that are planted apply as close to the soil as possible. Our products will not harm the plants but if left on the leaves will not help the soil. Rinse it off of the plants with additional water. Our products can be applied over the top of ground cover or compost, but just like with planted area water long enough after applying to wash off ground cover or compost and into the soil.

Additional Application Information

  1. ClayMend is an inexpensive liquid amendment that is easy to apply directly to your lawn, garden or around your trees and shrubs. When possible, working ClayMend into your soil helps accelerate the process of opening your clay soil. When using ClayMend on your lawn, aerating it before applying ClayMend may help speed up the restructuring processes.

  2. A single application will provide improvement to your soil but we recommend applying ClayMend 4 or 5 times during the first year of use for accumulated improvement to your clay soil. After that apply ClayMend once or twice each year (spring and or fall) to continue improving your clay soil.

  3. As microbes process old plant residue they can leave your soil with the ability to hold more water and nutrients.

  4. Microbial soil restructuring can be sustained for longer periods of time than other soil amendments.

  5. Repeated use can make continuous improvements to your soil.

  6. ClayMend can be applied when temperatures are hot or cool even while it is raining.

How PetiGreen works

Here is How ClayMend Works

Clay soils typically do not have the right environment to support a high enough population of soil microbes that are needed to support healthy plant growth. ClayMend helps improve the environment of the soil so that over time it can support a large population of soil microbes which in turn support more healthy robust plant growth.

Safe when Used as Directed

ClayMend is Safe for Kids and Pets when Used as Directed

ClayMend is safe for pets and kids when it is applied as directed. Apply ClayMend to your lawn or garden using a hose end applicator and then wash it into the soil after each application with your sprinklers.

Application Temperature

ClayMend can be Applied During Cool or Hot Temperatures

ClayMend can be applied any time of year even in hot and cool temperatures. It can be advantageous to apply ClayMend in the fall or early spring when moisture in the ground is not as likely to evaporate as it might during hot summer days.
Apply when normal daytime temperatures are above 45° F. Microbial activity will go in and out of dormancy as the temperatures drop below 40° F and become active again above that temperature.
ClayMend can be applied even in hot temperatures and will still help improve the soil. We recommend applying it during the cooler part of the day, typically mornings are best. Summer heat can get to a point that it stresses grass and other plants even though biological activity is increasing and soil conditions are improving. Don’t worry about using ClayMend in the summer heat.  It will work to improve the soil even in sweltering heat.

Keep Lawn Watered

Keep Your Lawn Adequately Watered

You should keep the lawn and garden adequately watered so the grass and plants gets a sufficient amount of water and there is enough moisture for any seeds you plant to germinate.
You should avoid too much water because it can hinder beneficial microbial activity and increase the chance of detrimental fungi.

Cut Fertilizer by at Least Half

You can Reduce Fertilizer Pollution

ClayMend helps improve the efficiency of your fertilizer. Typically you can reduce the amount of fertilizer you apply sometimes by up to 30% especially if you mulch your grass and dig your old plant matter back into the soil after each season.
Mulching your grass clippings can help reduce the amount of additional fertilizer you use on your lawn. It can return up to 2 lbs. of nitrogen per 100 sq. ft. over the course of a year and it is organic and more balanced than chemical fertilizers without putting immediate stress on your lawn.

All Natural

ClayMend is All Natural

ClayMend is all natural consisting of naturally occurring ingredients including a proprietary blend of organic acids, beneficial soil microbes, nitrogen and sulfur.


PetiGreen can be mixed with ClayMend

ClayMend and PetiGreen can be Mixed Together

If you have dogs and need to address urine spots in your lawn you can mix ClayMend and PetiGreen together and apply them both at the same time.

Neutralize Dog Urine

ClayMend and Soil pH

Microbial activity helps drive soil pH toward neutral. As the environment of your clay soil improves, higher microbial activity can occur and the higher this activity the harder the soil is pushed toward neutral.

Safe for Vegetables

ClayMend is Beneficial to Vegetables, Lawns and More

ClayMend was designed to be used to improve clay soil for crop growth but it is also beneficial for other plants including lawns, shrubs, flowers and trees.


Frequently Asked Questions

Will PetiGreen Benefit My Lawn Even If I Don’t Have Pets?

Even for people who don’t have pets PetiGreen is a great soil amendment for your lawn. We like to think of PetiGreen as an amendment for lawns that has the side effect of preventing pet urine spots over time. Whether there is a pet in the picture or not, the same benefit occurs in improving the health of your lawn by improving the environment in the soil so that beneficial microbes can flourish. This helps improve the efficiency of fertilizer so you can typically cut the amount of fertilizer you use in half.  In addition PetiGreen helps naturally aerate the soil. It will also help process excess nitrogen that may have built up over the years that negatively impacts the growth of your lawn and make that nitrogen more available to the lawn.


Is PetiGreen environmentally friendly?

Not only is PetiGreen is environmentally friendly, it promotes the environment of the soil with true organic activity in the soil that helps in the reduction of fertilizer pollution and the conservation of water.

PetiGreen is made up of a proprietary blend of naturally occurring components that build the health and fertility of the soil. Healthy soil is more efficient at metabolizing dog urine.

Fertilizer pollution is an escalating problem in our world and by working with Mother Nature our products build the health and productivity of the soil naturally, we call it being “Powered By Mother Nature”. Products developed with mother natures own systems are beneficial to the environment as well as safe for your family and pets.


Will PetiGreen protect my grass from urine if I have more than one dog?

Yes, although you may need to apply PetiGreen more frequently.  It takes time before the microbes can prevent spots from forming but after a few months if you notice new spots are forming but are much smaller, you might adjust your schedule to every 5 weeks.


How often will I need to apply PetiGreen to protect my lawn from dog urine spots?

Applying PetiGreen every 6 weeks is adequate for most homeowners.  The dog keeps peeing on the lawn every day and it is important to keep on the 6 week schedule to build up protection and then to keep the lawn protected.  If damage to your lawn is severe and it is within your budget, you can apply PetiGreen every week for the first 6 weeks to help accelerate the recovery of those severely damaged lawns.




What can I expect after applying PetiGreen to my lawn?

Most customers see improvement in their lawn growth within  2 – 4 months even though they will still be getting pee spots.  Over time you’ll notice a reduction in the size of new pee spots and eventually, typically around 4 – 6 months for many lawns and 6 – 12 months for severely damaged lawns, the new pee spots fade away.

Even though it takes time for the microbial population to increase large enough to prevent urine spots, they can usually process enough nitrogen from the pee spots in just a few weeks so that new grass seed will germinate.  This helps keep your lawn greener while the population grows to the size that it can prevent the dog urine spots from forming.

The PetiGreen Routine is an essential the tools that helps to eventually control and prevent dog urine from killing your lawn.  Following the PetiGreen Routine natural aeration is improved, organic carbon is built up, fertilizer and water efficiency improves and that results in an even healthier lawn over time.

We recommend reading our Getting Started page when starting to treat the dog urine spots in your lawn.


Should I put PetiGreen just on the pet urine spots or can I treat my entire lawn?

PetiGreen should be applied either to the whole lawn or to the area your dogs use not just the spots.  PetiGreen works to improve the soil too the point that it will support a population of microbes that can eventually prevent dog urine spots from forming.


Can PetiGreen be used at a heavier than recommended application rate?

Yes, you can use up to 10 times the recommended amount of PetiGreen without damaging the lawn.

Application rates less the recommended rates will diminish the effectiveness of PetiGreen and are not recommended.


Will PetiGreen harm my flowers or other plants?

PetiGreen is a unique blend of soil conditioning ingredients optimized to protect your lawn from dog urine spots, but it will also improve the health of all your plants including flowers, vegetables, shrubs and trees.

Even though PetiGreen will not harm your plants it works in the soil so if you spray it on your flowers, vegetables, shrubs, trees, etc. makes sure you rinse it off of the plants so it gets into the soil where it can go to work to improve the soil.


How does PetiGreen keep dog urine from killing my lawn?

PetiGreen improves the environment of the soil so a larger population of microbes than the soil can normally support can survive.  When the population of microbes reaches a large enough size they can process the excess nitrogen from the dog urine more rapidly than the nitrogen can kill the lawn.  It takes time to reach a population that will prevent dog urine spots in grass but as you are using PetiGreen and the population is growing it can become big enough in just a few weeks that it can process enough nitrogen from the grass that new seed will usually germinate and start fill in the burn spots.  Eventually the soil environment improves and the microbial population increases enough that the nitrogen can be processed before it has a chance to damage the grass.



Should I start using PetiGreen before the cold winter weather or wait until spring?

PetiGreen should be applied as soon as possible regardless of the time of year, provided the ground is not frozen, so it can start building the microbes in the soil which is ultimately what protects your lawn against pet urine spots.  In areas where daytime temperatures are 45° F to 50° F or warmer during the winter it is best to use PetiGreen throughout the year since damage to roots can occur even when the grass is dormant.

In colder climates the microbial population will expand until the cold weather hits and then it will go dormant.  In the spring that expanded population will come out of dormancy and pick up right where it left off.  Then just continue with the program to improve the soil and expand the microbial population even more until your lawn is completely protected from new dog urine spots.


Will PetiGreen protect my new sod from dog urine spots?

PetiGreen is arguably the BEST soil amendment on the market for helping new lawn get established. It will help improve the underlying soil as well as release soil nutrients and encourage root growth.

With all these benefits, until the roots are established into the soil where they are protected from urine they are very susceptible to damage. PetiGreen will help quicken the root establishment process, but we advise trying to remove the dog from the new lawn if possible. Until the roots are well established you will see new urine spots.

Here is an article about Dog Urine and New Sod with more information that might be helpful.


Should I apply PetiGreen before or after I apply grass seed?

Start using PetiGreen about 3 weeks before applying new grass seed.  If you have been using PetiGreen for more than 3 weeks and you get new pee spots you can apply grass seed as soon as the new pee spots appear.


What are the ingredients in PetiGreen

PetiGreen is a liquid soil amendment designed to improve soil damaged by dog urine using a proprietary blend of naturally occurring organic acids, organic carbon, soil microbes with a little nitrogen and sulfur that work to keep the microbes dormant until PetiGreen is applied to the soil.


Will fertilizer affect PetiGreen and the Dog Urine Spots in my lawn?

Adding fertilizer to a lawn with dog urine spots can further damage the lawn and will increase the time needed for PetiGreen to control the damaged spots.  If possible we recommend NOT adding additional fertilizer to areas the dog uses until the urine spots have stopped and then fertilize at a reduced rate if it is needed at all.

PetiGreen increases the soils ability to process nitrogen in pet urine which contains an excessive amount of nitrogen. By adding fertilizer it will increase the amount of nitrogen the microbes in the soil needs to process.  It is nitrogen overload that kills the lawn and causes the dog urine spots to form.

Lawns that have been heavily fertilizing over the years can also be high in nitrogen. These lawns tend to have more severe urine damage where the dogs go and it can take much, much longer to process all that extra nitrogen before the soil improves enough to protect against new spots.  It is best in areas like these to keep the dog off the area if possible, to reseed after applying PetiGreen and letting the new grass get well established.  These soils can take months before they come around.

When there is an excess of nitrogen added to the soil, even when there are no pets, nitrates can build up and diminish microbial activity which impacts lawn and plant growth.  By cutting back on nitrogen use, using it sparingly and only when needed, you can actually achieve a greener, healthier lawn.

If you have fertilized already apply PetiGreen as soon as possible so it can start processing the fertilizer and begin to reduce the nitrogen overload in the soil.

It takes quite a bit of time for soil microbes to build to a population large enough to prevent new urine spots but as this population is growing a lot of nitrogen can be processed so that new grass seed will grow.  You’ll still get new spots but this will help keep your lawn looking greener until the microbes can prevent the new spots altogether.


Do I need to work or turn the soil to apply ClayMend or can I just spray it on?

You do not have to work the soil when applying ClayMend, however, working ClayMend into the soil will accelerate the restructuring process.  When applying ClayMend where you don’t work it into the soil you may consider applying a few frequent applications (every 5 or 6 weeks) to help accelerate the restructuring process maybe for the first year, then every couple of months as the soil improves eventually just a couple of times per year (typically spring and fall).

Applying ClayMend™ with an adjustable hose-end sprayer



Can I spray ClayMend on plants?

ClayMend can be applied where plants are growing including lawns.  Since ClayMend works in the soil even though it won’t harm your plants you will want to make sure your rinse it off of your plant to get the solution into the soil so it can improve the soil.


How often do I need to apply ClayMend and for how long?

When irrigation water is high in salt as one might expect from well water or reservoir water you will want to use ClayMend every 6 weeks.
Just one application of ClayMend will result in some improvement of your soil.  However you will get better results in plant growth with multiple applications.  Where clay is extremely compacted and where the soil can be worked we recommend a heavy initial application of ClayMend, maybe 2 or 3 times normal, and then 5 or 6 times throughout the first and every couple of months the second year.  After you notice significant improvement in your clay a spring and fall application should suffice.
Where clay is extremely compacted but existing plants restrict your ability to work ClayMend into the soil we recommend an application every 6 weeks for your first year.  The following year we recommend every two months and after that twice a year.


Is ClayMend safe to use around Pets?

ClayMend is safe to use in areas where pets will be when used as directed.  We recommend treating ClayMend as you would other fertilizer products keeping pets away while applying it.  Since the product does not have any benefit until it is in the soil just make sure that you water it in wherever you use it and after that you can let your pets on those areas.


Can I use ClayMend around water features with fish (Ponds, etc.)

ClayMend can be used around water features such as ponds with fish and other aquatic creatures.   It contains naturally occurring organic acids that occur in soil including the soil around the water.  The microbial population that ClayMend encourages is aerobic so any residual microbes that may result in the population expansion and end up in the water would perish from the anaerobic environment of the water.  As always, exercise good judgment when applying ClayMend by reducing water flow of the applicator around the water feature so that the soil amendment gets into the soil where it is beneficial and over spray is at a minimum.  We recommend keeping a border of a foot or two from the edge of the feature.  Over time the microbes in those areas should migrate to the untreated border.


What are the ingredients in ClayMend?

ClayMend is a soil amendment designed to improve clay soil using a proprietary blend of naturally occurring organic acids and soil microbes with a little nitrogen and sulfur.


Can I use PetiGreen and ClayMend at the same time?

Yes, you can mix PetiGreen and ClayMend and/or any of our other soil amendments together in the applicator bottle at the same time but you must use all that you mix at the time you mix them.

Do not dilute or mix products together and try to store them as the microbes may become active and react in the storage container and may leak or break the container.

Do not mix any HumicGreen products with other brands of products.


How do I apply PetiGreen?

Apply PetiGreen with a hose end applicator that is designed for liquids.  Unlike many fertilizers, herbicides, pesticides, etc. PetiGreen does not rely in a ratio of product to water but instead is based on ounces of product per square feet of lawn regardless of how much water is used.  We are only using the additional water as a carrier to give you more time to get the product out of the applicator and applied evenly to the area.

An example of a normal application covering 2400 sq. ft. would typically be to use 7 ounces of product and add some water to the product in the applicator.  You could add 12 ounces of water or 20 ounces of water and it would not make a difference as long as you make sure it is all applied evenly over the 2400 sq. ft. area so that all 7 ounces of product are applied to the lawn.

Applying ClayMend™ with an adjustable hose-end sprayer



What type of Applicator should I use?

Use a hose-end sprayer or for smaller area you can use a watering can.



Do I have to remove the dead grass when reseeding?

Generally you do not have to remove the dead grass when reseeding the dead spots.  Simply scatter grass seed in the dead spot and make sure it falls through the dead grass and makes contact with the soil.  The dead grass will actually shade the new seed reducing the possibility of damage from the sun.  If the dead grass is so dense that the seed does not drop through it to make contact with the soil you can fluff it up so the seed will drop through it.


Will ClayMend harm grass seed or new grass growth?

ClayMend will help improve the soil and the microbial population so that grass seed will have an easier time germinating and the new glass will have an easier time establishing new roots.  We recommend applying ClayMend before putting new seed down simply so you don’t wash the new seed away.


Can I put PetiGreen on new sod?

Yes, even though it won’t be able to protect the new sod until the roots of the new sod gets established, PetiGreen can help new sod get established more quickly.


How is ClayMend different than fertilizer?

ClayMend works to improve the environment of your soil so that it can process and store fertilizer into a form that your plants use.  ClayMend is used with fertilizer not instead of fertilizer.

Fertilizer is the food your plants need but it does nothing to improve your soil or improve the ability of your soil to process it for storage consumption by your plants.

You might think of it like how you would eat a walnut.  A walnut is a food you can enjoy but you can only eat it when you crack open the shell to get to the nut.  ClayMend works in a similar way of cracking the shell of fertilizer so the plant can get to the nutrients they need.
