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. 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B003AYWG46 | | Best Sellers Rank | 444,256 in Garden ( See Top 100 in Garden ) 840 in Grass Seeds | | Brand | Jonathan Green | | Brand Name | Jonathan Green | | Colour | Green | | Customer Reviews | 4.4 out of 5 stars 2,447 Reviews | | Global Trade Identification Number | 00079545103231 | | Item Type Name | Black Beauty Ultra Mixture | | Item Weight | 11.79 kg | | Item weight | 11.79 kg | | Manufacturer | Jonathan Green | | Manufacturer Part Number | 10323 | | Material Features | Natural | | Material feature | Natural | | Model Number | 10323 | | Number of Pieces | 1 | | Plant or Animal Product Type | Fescue, Kentucky bluegrass, Ryegrass | | Sunlight Exposure | Full Sun | | Sunlight exposure | Full Sun | | UPC | 079545103231 | | Unit Count | 11829.4 millilitre | | Unit count | 11829.4 millilitre | ## Product Details - **Brand:** Jonathan Green - **Colour:** Green - **Global Trade Identification Number:** 00079545103231 - **Item weight:** 11.79 kg - **Material feature:** Natural - **Number of pieces:** 1 - **Sunlight exposure:** Full Sun - **UPC:** 079545103231 - **Unit count:** 11829.4 millilitre ## Images ![10323 Black Beauty Ultra Mixture, 25-Pound - Image 1](https://m.media-amazon.com/images/I/61QHzcleAVL.jpg) ## Questions & Answers **Q: How to plan the seed—walk around my land and throw it on the land by hand? Pour the seed into the machine letting the machine disperse the seed??** A: Overseeding use a walk behind spreader or by hand which is difficult to get uniform spread. On dirt scratch rake down an inch or more spread seed lightly rake it in and top with 1/4 inch of peat moss. If ground is compacted aerate then seed. Fertilize and weed killer should only be used on tall fescue between September and May. I am in New Jersey check your climate zone. Fall is best for planting otherwise early Spring after last frost. Love the seed germinates well and is consistent. **Q: will the grass stay green for the summer months in Dallas, Texas?** A: Probably not the best option for Dallas summers and don’t try to seed in the spring or summer. You might be ok to overseed this fall. **Q: Is this a good over seed for the Central Florida Nature Coast area, Zone 9** A: You should be able to check the web site to see if it is recommended for your zone. I'm happy with the seed in Virginia, zone 7. **Q: Will this work in Maine?** A: I don't see why not. My brother lives in NH and have used the Jonathan green products and says he loves them. I just know this grass seed is awesome. I tried the other brands and last spring put down this stuff, and within like 2 days it sprouted. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Truly Superior Grass Seed! *by D***. on 26 May 2024* Marvelous grass seed.
