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. Review: No junk fillers and it comes in beautifully! - 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. ## Features - ESTABLISHES NEW YARDS & FILLS IN BARE SPOTS - Black Beauty Ultra Grass Seed quickly germinates for the fast establishment of newly seeded lawns.

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.

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. ## Frequently Bought Together - Jonathan Green (10324) Black Beauty Ultra Grass Seed - Cool Season Lawn Seed (50 lb) - Jonathan Green (16008) Veri-Green Starter Fertilizer for Seeding & Sodding - 12-18-8 Starter Lawn Fertilizer (15,000 Sq.
