Jonathan Green (10620) Black Beauty Dense Shade Grass Seed - Cool Season Lawn Seed (7 lb)

Beautiful color, quick growth

Great quality seed. Very easy to use and guaranteed growth in the shade.

Beautiful grass! It took a while to germinate the first time—probably because I didn’t do much soil prep, just spread the seeds on top, and the weather was cold for a couple of weeks. Once the temperature warmed up, it started growing much faster. On my second try, I tested a smaller patch and did a few things differently: I lightly covered the seeds with a thin layer of soil and watered twice a day. The instructions suggested watering up to four times daily, but I didn’t have time for that—twice a day still worked really well. It sprouted within a week and looked great. Definitely recommend, especially if you can give it consistent care!

This is excellent grass seed. In the past, whenever I bought a $30–40 bag, it seemed like only a small portion was actual seed and the rest was filler—fertilizer, weed control, or other additives. This product is 100% grass seed, which made it feel like a much better value and exactly what I was looking for. As the photos show, the hardest part was the prep work. I weeded the entire backyard and turned over the soil by hand, which took about 12 hours. But that effort paid off. Three weeks later, I’ve got solid coverage. After seeding, I bought a sprinkler and watered for about 20 minutes each morning and evening. The results so far have been excellent. I probably overseeded a little—I used the 15,000 sq. ft. bag on an 800 sq. ft. area—but it definitely contributed to the results.

This may be a good product for other soils and shaded conditions. Unfortunately, it did not grow in our soil in an area between two wooden fences that gets little sun.

best seed i ever purchased

I have not used this variety of seed, but have used Jonathan Green seeds before and they are great. I can't judge this yet, though. It takes about 10 to 21 days to germinate, and they are asking for a review 3 days after I got the seed.

The name says Dense Shade, but don't believe it. We worked hard for two weeks preparing our yard before planting this seed in our backyard, which gets sun for half the day and is shaded for the other half. We bought a 25 lb bag from Amazon and picked up 2 more 5.6 lb bags at Home Depot to finish up on March 23rd. By October, very few spots of grass had grown. I don't know if the seed was old or what the problem was, but today, our yard looks just as barren as it did before we started reseeding last year. We are very disappointed with this product!

Very happy with the product. Germinates in 3 to 4 days,

So far no grass but maybe too cold? Will try again in the spring

this grass seed was for areas of my lawn which on both sides have trees which are dark areas. i have just looked at the growth today and there is hardly any grass there. all in all this was purchased to give growth in my dark areas and it did not do that. it was quite expensive as well .

shadey side of house with trees covering would not grow grass until this stuff! great product, came up quickly and has grown nicely!

Very fast germination & coverage however does not survive the UAE summer 😑
