About Grassology

Grassology is a patent pending grass seed mix that claims to reduce mowing, fertilizing, watering, and weeding. In addition, Grassology claims to guarantee “great green grass,” while also defending against insects and disease.

You want the greenest grass on the block, and you probably just watched a commercial for Grassology, hosted by none other than Bob Vila. And it totally sounds awesome, right?

But is there any merit to these claims? Let’s find out in our review.

How Grassology Works

Grassology is a “dwarf height,” ultra-low maintenance grass seed mix that claims to grow a longer root structure than other types of grass seed. As a result, you’ll have to mow, fertilize, water, and weed less. On top of this, Grassology is even guaranteed to give you “great green grass,” while also defending against insects, and disease.

What about the Claims?

Are the claims true? Probably not and here's why: In short, Root length and growth rate often have much more to do with the amount of water your grass receives, not necessarily the type of seed you use. For a full explanation, please see the Bottom Line section.

Grassology Pricing & Refund Policy

Grassology is currently priced at $14.99 plus $7.99 shipping and handling. Like most “As Seen on TV” products, you can purchase a second bag of Grassology for $9.99, at which point you’ll also receive a 25’ Pocket Hose Ultra.

Grassology comes with a 30-day, 100% satisfaction guarantee, less shipping and handling charges. In order to begin the refund process, you’ll need to contact customer service at 800-597-1622.

What are Consumers saying in their Grassology Reviews?

Based on a few months worth of Grassology Reviews we've accumulated, most customers complain of poor service, difficulty cancelling orders, and underhanded selling tactics. Regarding the product specifically, the most common complaints cite failure to work, poor seed quality, and that Grassology is simply a rebranded mix of Pearl’s Premium. Also, Because of the fescue and Kentucky bluegrass mix contained in Grassology, if you live anywhere in the Southern region where summer temperatures can be extreme, you may want to steer clear.

Bottom Line: Should you buy Grassology?

With all this in mind, what’s the deal with Grassology? We might hesitate to call it a scam, but there are definitely some red flags to consider. These include:

There is no seed mix list provided on the Grassology website, so you don’t know exactly what you’re putting on your lawn. On top of this, seed types are best suited to different climates (also known as “growing zones”), so you can’t be sure that the Grassology seed mix will even be ideal in your climate. However, it’s very likely that you could purchase a better quality mix specifically tailored to your climate at your local lawn maintenance store.

Next, while Grassology claims to come with a 30-day money back guarantee, this really isn’t enough time to see if it works for you. Because of this, we would highly recommend purchasing Grassology at your local Wal-Mart, Target, or Bed-Bath & Beyond. This way, you’ll be able to avoid poor customer service should you wish to return it.

Finally, keep in mind that if your lawn has numerous dead patches, excessive weed growth, or bald spots, Grassology will not be enough to make it green. Instead, you’ll need to apply additional lawn treatments beforehand.

  • Doesn't work

    I bought 2 pounds of the Grassology seeds a few weeks ago. I tilled and fertilized the backyard, watered everyday for a week, and never saw any grass. I then tilled and watered for a second week, and still saw no grass. I believe the seeds were 2 years old.

    Bottom Line: No, I would not recommend this to a friend

    Not sure what the seeds consists of, but I never got one blade of grass. I've seen the seed but it did not germinate.

    So far so good

    • Dontana, CA,
    • Oct 4, 2015

    I saw the bag of Grassology and bought it. I thought why not. I have nothing but dirt and I really want grass. So I read the directions and went for it. 4 days later I see grass appearing. I couldn't believe it. Bright, lime green grass. Wow! Everyday it gets thicker and more shows up. Thank you Grassology.

    Grass seeds are no good

    • Sep 9, 2015

    This Grassology is a scam. It does not grow. I bought 20 lbs. as filler for my lawn nothing grew. I wish I could get my money back. No. I would NOT recommend it to anyone. Take it off the market.

    Bottom Line: No, I would not recommend this to a friend

    it doesn't grow

    • San Diego, CA,
    • Aug 23, 2015

    This is a scam of sorts. I bought about $250 worth of grass seed and received four pocket hoses. Two of the hoses are no good, leak like sieve. The grass just simply doesn't grow very well. In the two places it did grow, it is very tall and not very dense. I would not waste a dime on this product.

    Bottom Line: No, I would not recommend this to a friend

    Very bad.

    • Omak, WA,
    • Aug 16, 2015

    I replanted my back lawn with this seed and I have no grass. It's an entire back yard of weeds. I am so upset with this. Don't buy it. Now I have to save money and start over. This product is a crock. Don't buy into there scheme. I'm sure Bob doesn't care what he puts his name on. He should endorse toilets, but then again I'm sure they wouldn't be worth what you put in them either. It only lets you give a minimum of 1 star. I don't give it a speck of one.

    Grassology Seed

    • Highland, CA,
    • Jul 31, 2015

    Planted seed and 14 days later no grass is showing. Seeded a new spot and 11 days later no grass on the first spot or the second spot. Whatever Grassology sent me did not grow.

    Rip off!

    • Tucson ,AZ,
    • Jul 30, 2015

    We carefully planted and watered the seed as directed. After 4-5 weeks, not a single blade of grass has appeared. Of course, it's now past the 30 day refund period! Don't believe a word of their sales pitch.

    We love our Grassology lawn!

    • Eagle Mountain, Utah,
    • Jul 16, 2015

    We have a Sandy hillside lot. I wanted a lawn that didn't require as much water or need to be mowed as often. We used Grassology. My neighbors have been envious of our lawn. It is low growing, requires a fraction of the water as our neighbors lawns, and maintains a dark green color. We couldn't be more pleased. We bought the seed at Wal-Mart, but have not been able to find it there anymore. I would like to expand our lawn. It us better and nicer than expected.

    Poor, do not buy

    • Decatur, IL,
    • Jul 15, 2015

    I saw no significant improvement with Grassology either way as compared to Kentucky Blue. Also the Pocket Hose is a Joke because it busted after a few uses.
