Does your Richlawn Turf Food get old or expire?

Richlawn Turf Food does not expire or lose its effectiveness as long as it remains dry and granulated. It is important to store it where it does not get moisture or it will cake up and render it unusable in the fertilizer spreader.

Hi. I have two small dogs, and I am trying to find a fertilizer that will green my lawn and present no danger to my dogs. How long would I have to wait before letting my dogs walk on the grass after fertilizing it?

Any of the Richlawn products can be used on your lawn and are safe for pets to be on the grass right after application. Follow the label directions and water the turf fertilizer in and once it’s dry, the dogs can romp about. Unlike some fertilizers that contain herbicides or fungicides, Richlawn is organic-based and does not contain harmful attributes

I'm interested in doing my own fertilization this year. Overwhelmed with how to proceed. Will you assist me which of your products should be used when? Also, do you recommend a drop or broadcast spreader?

I would recommend our Pro-Rich Turf Food. It has a higher nitrogen content which is ideal to get the lawn off to a healthy start. We have a fertilizer reminder that we send out over the season as the time comes for the next application. You can sign up for it on our website. As to the spreader, the type whether it is a drop or broadcast doesn’t really matter. It’s just a matter of personal preference.

I recently moved to the Denver area from Michigan. I have always been a Scott's fertilizer, but some of my neighbors told me I should switch to your Richlawn Pro-Rich. Why should I do that?

Because our soils are very different than other parts of the U.S., more alkaline and lacking in organic matter, fertilizers can make a difference in how plants respond. National brands are okay, but lack some of the micronutrients that are needed in our regional soil conditions. Richlawn fertilizers are formulated for the Rocky Mountain Region, plus they are organic-based and overall will help improve the structure of our alkaline, clay soils.

I am planning to apply Richlawn Turf Food, but possible snow and colder temperatures are expected. Is it safe to apply your product under these conditions?

It is perfectly safe and ideal to apply Richlawn organic-based lawn fertilizer prior to moisture. Cold temperatures will not inhibit the effect of the fertilizer. If you can, core-aerate the lawn prior to fertilizing so the nutrients will filter down into the soil and increase assimilation.

Why cant i get 5-2-3 fert in California anymore used to buy it all the time?

I am not familiar with a 5-2-3 analysis fertilizer.  Would you happen to remember the brand name?

I made a mistake, and put down the Richlawn Winterizer, instead of the Turf Food. I'm scared I screwed up bad. Will my lawn survive?

You can use any of our fertilizers at any time of the season without and concern for damage.

Thanks for your note.

I've been using Scotts Turf Builder products for years (including Turf Builder + Halts in April) but am interested in trying Richlawn. What should be my annual schedule?

Thanks for your note. I would recommend following the holidays for an easy way to fertilizer.
Memorial Day
July 4th
Labor Day
If you need to during the season, use a liquid herbicide that allows you to target the weeds so you're not applying herbicide to the entire lawn. Regular applications of our fertilizer will thicken your turf and expand the root system to choke out many weeds in the future.

I hope this helps!!


Where can I find Pro Rich in my area? North Idaho 83815

We have a distributor in Spokane who recently received a shipment of Pro-Rich. I would recommend calling them for the name of the nearest dealer.

Thanks for your note.

Can too much Rich lawn turf food burn your yes? I had beautiful lush green grass and now I have patches of dried looking grass after applying Rich Lawn. I water immediately after application, but I am not watering everyday. I swear by this product, but don’t understand the dry looking spots. Thanks

Thanks for your note. There are several causes for brown spots in a lawn including-
Severely compacted soil
Insect damage
Lawn Disease
Not enough water
Mold from snow accumulation over the winter
It would be very difficult to burn the turf with our fertilizers. If you would like to send some photos, I would be happy to take a look and see if we can figure out what's going on.

where can I buy EKO Lawn Top Dressing near me ? - Centennial Colorado 80122 ?

Thanks for your note. EKO Top Dressing is available at these dealers in your area-

Tagawa Gardens Centennial
Big Toolbox- Parker
Big Toolbox - Centennial

I have a brand new sod lawn that was put in last fall in the front and a couple weeks ago in the back.I can't do anything in the back at this point but the front has some broadleaf weeds coming in and I need to get rid of them do you offer any kind of weed spray? Also if I look at your calendar I'm planning to use those product each month that the calendar shows for the time of year. Is that the proper way to use your product?

Thanks for your note. We don't have any type of week killers, but there are some good ones out there. I would recommend one that allows you to target the specific weeds, so you're not unnecessarily spraying the whole lawn.
It's not necessary to fertilize once a month. About every 7 weeks ideal throughout the growing season. We are re-doing the fertilizer calendar because it is a bit confusing.

With watering restrictions can we apply rich lawn pro rich earlier in the day and apply water at 6pm.

Thanks for your note. Pro-Rich does not need to watered-in right away after application, so that is no problem. It is best for the grass though if it is not damp overnight. That is the source of several lawn diseases.
The earlier in the day you can water the better. Or just before the sun comes up.

I have lots of dandelions and thistle in my lawn. This is my third year trying to control the weed by pulling - I'm losing the battle and the grass looks distressed. What natural product or treatment do you suggest to begin to bring this lawn into a more healthy state? THanks for your advise.

Thanks for your note. Unfortunately, for now there is no natural weed killer on the market that is effective. There is a vinegar product, but it kills grass as well, and pulling them by hand only breaks off the top part, and as you have seen, they come back because the root is still alive.
I would recommend a good broadleaf weed killer that allows you to spray only the weeds, and not broadcast it over the entire lawn. Once that is done, regular applications of our Richlawn Turf Food or Pro-Rich Turf Food will thicken your turf and choke out many weeds in the future. Our fertilizers also improve the soil and expand the root system so your lawn will need less water and will survive the stresses of winter and summer healthier.
I hope this helps!!

Hi again, It has been a month now since I inquired about the Richlawn Turf food in my local Home Depot. You responded saying we should be seeing it in a few weeks. I spoke with Home Depot in Durango the other day, and I was told they were having trouble getting the Richlawn Turf Food in and was not able to get any. Is this true, or is it just their incorrect answer? Thank you, R Messier

The store manager and I have both been trying to get it done,  but it has to be approved by corporate. We're well in to the season now and I doubt it will happen this year. ACE Hardware might be a better option and any store can bring it in from their DC in Colorado Springs. Their item number for it is 7174915.

Thanks for your persistence. It means a lot to us.

I have necrotic ring spot fungus in my lawn here in Greeley Colorado. I was told the only treatment for this fungus was to apply a combination of super soil stimulant and elemental sulpher to my lawn. I was also told this would take 3 seasons to fix and see results. Therefore, my question is, how would you fix this issue and would it be cheaper than using a lawn care company? Any and all assistance and help would be greatly appreciated and respected. Thanks for your time and help. Barry Harding

This is a complicated question. NRS is usually caused from poor watering habits, inconsistent fertilization using products with high nitrogen that break down quickly or highly compacted soils. I'm not familiar with a super soil stimulant, but sulfur treatments will help because sulfur will help to lower the pH which will slow down or even stop the progression of the NRS.
It's difficult to say how long recovery could take. If your lawn is in reasonably good health, it could be as short as one season.
Here are some things to do to help-
Raise the blade of the lawn mower
Regular watering but not to excess
Balanced fertilizer like our Richlawn Turf Food will help because it is a slow-release nitrogen that provides growth at a natural rate.
Use Richlawn Iron-Rich monthly to provide iron and sulfur
If you overseed, use turf types that are high in perennial rye and fescue, and not bluegrass. Bluegrass lawns are the most susceptible to NRS
You could accomplish this doing it yourself and save money Vs a lawn care company.

I hope this helps. If you have any other questions, please let us know.


My broadcast spreader wasnt working properly so some of the lawn ended up with a double dose of Pro-Rich. Will this harm the grass?

There shouldn't be any damage. Just water a few minutes longer to dilute it so it will break down.

Thanks for your note.

Specifically, what are the ingredients that are in EKO compost? Manure, straw, wood??? Does it have some kind of stamp of approval by the composting council of US? Thank you.

EKO Compost consists of poultry manure that is OMRI certified organic, and pulverized virgin wood.

Thanks for your note.

Is hog fuel/clay buster ok as mulch for garden path.

Hog fuel can be a little rough to walk on depending on how it was processed, but it certainly can be used in a garden path. Clay Buster is a soil amendment and is better used for that purpose rather than a pathway mulch.

I hope this helps. Thank you for your note.

How long does my pets and children need to stay off the lawn after fertilizing before it is safe

Our fertilizers are safe for kids and pets, but it should be watered in and let dry before much foot traffic. More so that it doesn't get tracked in to the house than for their safety.

Thanks for your note.

I have an established planting area with knockout roses and boxwoods. The original landscaper, just dug a single hole and amended the hole and planted each plant. The plants are surviving, but not thriving. Soil is clay primarily. Advice?

Assuming that the plants have been in their locations for at least a season or two, a good fertilization about once a month and regular watering should be all they need. We have a product that is called Richlawn Organic 100 and it is available at Home Depot and Lowe's stores. It come in a 40lb bag, and it is a great organic fertilizer for any type of plant in your landscape including your lawn. It is OMRI certified organic. If
If they are experiencing an issue with drainage due to the clay soil, use a bamboo stake around the plants to help aerate and improve drainage. Poor drainage is very common in our clay soils.

Thanks for your note. I hope this helps.


I have areas of my lawn that are uneven I would like to level them out. The underlying soil is clay. What do you recommend? Thanks!

Thanks for your note. We have a product called Earth Essentials Top Soil that would work well for your situation. Apply it at about a half-inch depth to the low areas. Allow the grass to grow up beyond it and then re-apply as necessary repeating the process until your lawn is level.


Hi, where can we recycle those plastic bags (seeds, top soil, etc)? Thank you

I would recommend that you ask your nearest garden center if there is a facility that they use for plastic recycling. One of the larger centers like Echter's, Nick's O'Toole's or Tagawa Gardens would probably have some information that would help.

Thanks for your note.

Where can I get Turf Food - live in Tulsa Oklahoma. HELP

Thanks for your note. We don't have any retailers in Oklahoma right now. We don't have enough of the raw material to expand out of our primary sales area which is Colorado. Hopefully, in the near future we will be in your area.

How can I order your rose products zip 44024

Thanks for your note. Unfortunately, our products are only available in Colorado. We just don't have enough raw material to expand beyond that. Hopefully at some point in the near future, we will.

Hi - I'm located in Denver, CO and was wondering which fertilizer you recommend for use now to get my lawn ready for the summer. I was also wondering if you had any tips on how to limit urine damage to my lawn from my dogs. Thank you!

Thanks for your note. Our Richlawn Turf Food is an ideal fertilizer for the entire season from spring and in to fall. We have a winterizer product that is good to use for the last treatment of the year, which should be done in mid-late October.

As far as good damage goes, Revive makes a product that is specific to that issue. It is called Revive Dog Spot Treatment and is available at Home Depot and Lowe's stores.

Where can I find your fertilizer in or near arvada

Our fertilizers are available at: Home Depot, Lowe's,  Echter's garden center, Malara Gardens all in Arvada.


With high temps coming later in the week, do you advise against using Pro-Rich Fertilizer until a day or two of cooler temps? I'm following the eight week schedule.

Thanks for your note. Temperature is not really a factor with Pro-Rich. It is non-burning due to its organic and natural components. I would stay with your schedule. Just water as normal after the application.

What should we do if our dog ate some of the Grow Rich Rose food?

Ingesting fertilizer whether it's ours or any other should be avoided. All of the ingredients in our products are natural and organic, so the dog may vomit, but I have never heard of any other complications from eating a small amount. If you have any concerns I would recommend you contact a veterinarian who could give you more professional advice.

Thanks for your note.



Hello, Do you spread Iron-Rich with the same frequency as Pro-Rich? If yes, do you also use a spreader? Do you only spread Iron-Rich if your grass is yellow?

Thanks for your question. Iron-Rich is a supplement that is intended to be used in between regular ferilizations. I would recommend it be used from June to August when the lawn is stressed from the summer heat. It keeps the lawn green without forcing a lot of growth, which means using more water, and also more mowing.
You would use a spreader at 50% of maximum opening.



Is Nature’s Yield Organic Compost similar to EKO Organic Compost? Please provide a comparison between the two products.

Thanks for your question. The difference between the two products is Nature's Yield Compost also contains peat moss.

Hello, Home Depot in Boulder did not have the Pro Rich Winterizer available last fall-are there retailers in the Boulder area that do stock it? Thanks

Thanks for your question. Pro-Rich is sold at garden centers and ACE Hardware stores. Mcguckin Hardware will have it as well as The Flower Bin, and Budget Home Center in Longmont.


I have done a soil test the last 2-years via the MySoil brand test kits. My Nitrogen is low; Phosphorus very high and Potassium is okay. All other nutrients such as Iron, Magnesium, Sulfur, Boron, Iron are at or near optimum range. My lawn looks poor. My assessment is not enough water nor have I aerated in a few years. I power raked about 5-years ago and bag clippings as I was told they do not break down at eleveation- I am about 5800'. My lawn is bluegrass/fescue mix. I feel like I am doing the right things, but getting no results for the effort I am putting in. Any ideas on what I could do differently?

Thanks for your note. Soil tests are good, but the results can be misleading. Your soil structure could contain all of the proper elements necessary for healthy plant growth, but they get held up in the clay soil we have and never reach the root of grass or other plants where they can be used.
You didn't mention what fertilizer you were using or if you had applied any this spring. I would recommend you use our Richlawn Turf Food 4-5 times throughout the growing season at 7–8-week intervals. Aerating is also one of the best things you can do to improve and maintain the health of your lawn.
I would never recommend power raking a lawn in Colorado under any circumstances because of the damage that is done to the crown of the plant. And, as we move out of more moisture and into more of a hot weather pattern, regular deep watering will become more important. Colorado lawns need about an inch per week which equates roughly to 20-25 minutes twice a week.

I hope this helps. If you have any other questions, please let me know.

Your FAQ's are great! New Q: a mature bush in a bed bordering the lawn that gets fertilized by the HOA has yellow-ish new growth this year. Definitely not the rich green as past years. We've cleared the base to amend with compost to which we mixed a tad of coffee grounds, but wondering how to best restore the lush dark green color. Is spraying leaves with ferrous sulphate helpful? Iron-rich looks like a possibility; how should it be applied? how many applications & how soon to know if it's working? A chloric ginella (sp?) maple tree was removed from the lawn 6 years ago - 6 feet away! Coincidence? would hate to loose this beautiful bush! TK U !!

Thanks for you note and your kind words. Generally speaking yellowish leaves on an otherwise healthy plant is usually too much water, or lack of iron. We have had a fair amount of rain recently, so that is a possibility. If you feel it is, take a wooden or metal stake and poke some holes around the base of the plant to help aerate it.
If the veins of the leaves look darker than the rest of the leaf it is chlorosis, which would be my suspicion because you mentioned there had been a maple there. Iron-Rich would be a good fix for that. Just get a couple of handfuls and spread it evenly around the base of the plant and then water it in about once a month from now through the end of August.
If you would like to take a couple of pictures of the leaves and email them to me, I could give you more definitive information.
My email is

I hope this helps.
