It was a slow start due to excessive rain in our northern area, but things settled down and this seed has taken root and is growing. Our yard was bare due to large dogs playing and chasing each other and ripping up turf with their nails, so it is difficult to grow anything. We fenced the area we want to start with, cleaned up the debris, mixed up compost, manure, and dirt and put down about 2 inches on top of the broken, sandy ground. We then over-seeded the area and set up some soaker hoses. When the rains started the hoses were turned off as it was a torrential rain. Things dried out a bit and the hoses are back on and it is looking good. It is too soon to say how this grass will work out with our two rambunctious pups, but I will update. Seed was a bit expensive, but if it works out it is well worth it! This brand was recommended to me by another dog owner, and they have been very happy with it, and I did research grass varieties, sustainability, and the correct grasses for my zone before ordering. So far, so good. I would definitely order this again.

I never have good luck with growing anything in my yard, so I wasn’t sure how this would turn out. Things that I plant usually don't grow well, if at all. But this product was a home run. It makes me look like a lawncare professional. I started by using a scarifier to remove all the weeds and moss from my neglected lawn, then applied a 3-inch layer of topsoil before planting Jonathan Green Black Beauty Ultra Grass Seed. Honestly, I couldn't be happier with the results! Disclaimer: the right prep work + frequent watering is essential to bring out the best this grass seed can offer. If you don't plan to invest the time to do those things, don't bother buying this high quality, expensive grass seed (or any grass seed at all for that matter). Check out Youtube videos for instructions for the prep. I followed the Silver Cymbal Youtube channel's guidance and that worked great. A couple years ago, I bought this same grass seed and spread it across my yard with no prep or watering/maintenance, and that just didn't work at all. First Impressions: The packaging was solid, and the seeds looked high-quality. The instructions were clear and easy to follow, which was a great start. Planting Process: I spread the seeds using a broadcast spreader. The seeds have this special coating that helps them absorb water and nutrients better. Within a couple weeks, I started seeing little green shoots, and by the second week, my lawn was looking fuller and greener. I planted the grass seed in early April, which was a bit too early for my location, but it still turned out great. Applying peat moss on top was key to retaining moisture for the seeds to germinate. Peat moss is expensive but totally worth it. It's like a wet carpet after you water it. Lush, Deep Green Color: The standout feature? The lush, deep green color of the grass. It looks like a thick, green carpet, and the uniform consistency is incredible. The grass blades are fine-textured and dense, making my lawn look like a professionally maintained golf course. The thick consistency of the grass keeps weeds out without me having to do much of anything in terms of weed treatment or removal. I did spray mesotrione + surfactant when i planted the seed, which I believe was crucial to prevent weeds while the grass seed was germinating and growing. Drought and Disease Resistance: This grass is tough! Despite some dry spells, it stayed vibrant and healthy with less frequent watering. I haven't seen any signs of common lawn diseases either, which is a huge plus. Easy Maintenance: Maintaining my new lawn is a breeze. The grass grows evenly, so I don’t have to mow or edge constantly. It responds well to regular fertilization, and it’s stayed lush through different seasons. The downside: Now I have to mow my lawn more often, because the deep roots that these grass seeds have grown have caused the grass to grow faster than substandard grass seed might grow. Value for Money: Sure, it’s a bit pricier than some other brands, but it’s worth every penny. The transformation in my lawn’s appearance and health is amazing, and it’s super low-maintenance. Conclusion: Jonathan Green Black Beauty Ultra Grass Seed has completely transformed my lawn. The lush, deep green color and thick, uniform consistency make it look stunning. It’s easy to maintain and tough against drought and disease. Adding a layer of peat moss to retain moisture really helped it grow fast. Highly recommend this grass seed to anyone wanting a beautiful, hassle-free lawn. Five stars! Pro tip: save a bit of the grass seed in case you have bare spots that you need to fill in later.

I purchased this to oversee the front lawn in the fall, while a little slow to germinate it came up. in the spring the yard looked fantastic , it was worth all the effort.. will be doing the back yard in the fall. recently used the seed at an income property with a large dirt area from some construction, wasn't really expecting anything as it's late in spring season , also didn't get much rain or water and surprisingly it germinated. this brand is much better then other seed I have used. Actually I have been please with all Jonathan Green products.

I've used JG Black Beauty Ultra a few times now and have had pretty good success. There are so many different factors when growing grass that you can't always blame it on the seed. This seed has been good the past few times I used it with a decent germination rate and great looking grass. You do have to be patient as the tall fescue seems to take awhile to germinate, but once it starts to grow it doesn't take too long to start thickening up. It seems to be growing very well in my sunny areas, but my shady clay soil areas it's still struggling to grow so I would guess it's going to have a tough time establishing in areas with more dense shade or wet conditions. Overall this is a classic grass seed that's above what most big box stores offer.

I bought the Grass Seed Mix for an area in my backyard where I wanted to grow new grass. I did a lot of research before buying, and this seed mix was recommended to me. The bag is 3 pounds, and while it is a little on the expensive side, the quality seems very good. I planted it about two weeks ago, so it is still early, but the results so far are promising. I am already starting to see growth, and the appearance of the new grass looks nice so far. The texture also seems good, and I am hoping it will continue to fill in well. One important thing is that you really need to follow the instructions carefully. The soil needs to stay moist, especially during the first couple of weeks. If it dries out, the seed may not grow well. I also recommend using starter fertilizer and covering the area with peat moss to help keep the seed in place and hold moisture. Another tip is not to put too much seed in one spot. Try to spread it evenly, otherwise some areas may become too crowded while other areas look thin. I am using this in New Jersey, and so far it seems like a good variety for this area. It is still too early for me to fully judge long-term pest resistance, but so far the grass is coming in nicely and looks healthy. Overall, this is a good-quality grass seed mix. It is a little expensive, but based on the results so far, I think it is a good value for the money. I would recommend it, as long as you are willing to follow the watering and preparation instructions carefully.

I watched Youtube videos on different grass seeds and the results. I also read the reviews here. I didn't believe everyone with the negative reviews so I purchased based on my eyes and the Youtube videos I watched. My neighbor/friend, across the street also watched some reviews and decided to go with GCI rather than the Jonathan Green. I chose the Jonathan green because it was clearly a nicer looking grass once it was established. First, I ordered the 50lb bag by accident. The order came and it was 2 25lb bags which I was okay with. I roughed up my soil then laid down 4 yards of grade A topsoil from our local place. I've used them before and it was excellent. I used a spreader to lay the seed and waited. It was like watching grass grow. :) I ordered this on Aug. 28, 2025. It's now Sept 26, 2025. Some grass grew and some didn't. The photo on the left is GCI Grass. This was planted 1 month ago on a bare lawn. The photo on the right is, Johnathan Green grass planted 3 days later. My back yard which received most of the new dirt is even worse than the front yard! Take a look at the 3rd picture. Hardly any of it grew. You can see where I laid the new dirt vs where I ran out. I was going to order more dirt but I wanted to see how this turned out first. I have a few other gripes. I was going to return the Jonathan Green grass (Purchased off of Amazon) and they wanted $50.00! THEN, I looked around and found that I could have gotten the 25lb bag for $80. shipped had I not ordered directly from the vendor on Amazon. This was overall a very expensiive ($243.00 +tx) purchase and it's garbage. I'm going to see if I can return as defective because it's clearly defective. ***I'd also point out a few more things. I do my lawn twice a year at the same time. The sun beats down hard on it which is why I chose this particular seed. My lawn typically looks amazing by now. The final picture is what it looks like in November (and it will look like this in 3-4 weeks again but I'll be using a different seed). UPDATE: 9/29/2025 - The photos below may be out of sync with my message because when they are posted, they are re-arranged. Also, Amazon did refund me for this stuff. I guess you pay a little more for the Amazon order but in the end, they take care of you.

Marvelous grass seed. My large lawn needed a spring refresh and a bit of patch repair after the winter weather. In my research for grass seed, finding quality uncoated seed at an acceptable price was a bit of a challenge. Black Beauty Ultra has the right mix of grasses, it is not coated, it has a high germination rate, and a very low weed percentage. Although a bit spendy, the 25lb. bag is the best value. From my results, I found this product to be an absolute winner! As a cost-cutting measure, most major brand grass seeds available from the big box stores are coated with a green spray-on clay coating. This is marketed as an aid to germination, but frankly it is not nearly as effective as advertised. The industry is well aware that clay coating is far cheaper than grass seed per pound. The clay adds lots of weight to the bag... but does little to retain moisture. In my experience with patching and reseeding lawns, doing this during moderate spring weather is ideal and avoids the intense heat of summer and poor germination rates. The best results have come from first checking the soil pH and adjusting accordingly. Then, rake up the thatch on bare spots and lay down enough seed to fully cover the patch. Thoroughly cover the reseeded bare spots with a quality potting soil or topsoil. This is important... and works much better than a spray-on clay coating on the grass seed. Keep the area frequently watered throughout the day for at least two weeks until growth is established. While germinating, do not let the seeded area dry out and do not walk on or mow while the new seedlings are beginning to grow. Wait about four weeks after reseeding before mowing. Once mowed, fertilize with a low to moderate nitrogen lawn fertilizer. Newly planted grass is a bit sensitive for the first 3-4 months and can burn easily if stressed by high nitrogen fertilizers. It is now eight weeks since patching and reseeding my lawn with Black Beauty Ultra. The patches are completely filled in and the entire yard is evenly green, vibrant, and very attractive. Check out this excellent grass seed for yourself. You'll be glad you did.

I overseeded my backyard this spring with Jonathan Green Black Beauty Ultra Grass Seed and I’m extremely happy with the results. This is a quality seed mix with no junk fillers — just good, hearty grass seed that actually grows. It came up fast and thick. Within about 7-10 days I started seeing nice green sprouts, and after a few weeks it filled in evenly and looks lush. The grass is dark green, strong, and has that premium look you want in a lawn. It’s handling the summer heat and foot traffic from my kids and dogs. Spreading was easy with a basic broadcast spreader, and the germination rate was excellent. I followed the simple instructions on the bag and kept it moist until it established, and it really delivered.
