Jonathan Green Black Beauty Ultra Grass Seed Review

My Rating:

A lush green lawn is the desire of every homeowner, but it is often difficult to achieve. This is especially true for homeowners who live in arid or excessively humid climates. This is where the Jonathan Green 10322 Black Beauty Ultra Grass Seed Mix can assist. For more than 5 generations, the Jonathan Green name has been synonymous with beautiful lawns and gardens, the newest addition to their product line is no exception to this association. Through meticulous scientific research, the brand has created this seed mix to meet the challenges associated with growing green lawns.

The USDA requires that all grass seed be tested for germination and content. The Black Beauty Seed Mix is comprised of the following:

  • 30% Dakota Tall Fescue
  • 30% Montana Tall Fescue
  • 20% Tombstone Tall Fescue
  • 10% Blue-Tastic Kentucky Bluegrass
  • 10% Frontier Perennial Ryegrass

What makes this grass seed mix different from that of its competitors is that it is comprised of 100% grass seed. There are no fillers or other unnecessary additives in this mixture. This means that this seed mixture is guaranteed to germinate faster and fill in the damaged areas of your lawn more quickly and efficiently.


  • The 7 pound bag of Jonathan Green Black Beauty Seed Mix can be used to cover up 2,800 square feet for reseeding and 1,400 square feet for seeding new land.
  • The fescue, bluegrass, and ryegrass seeds used in this mix were chosen specifically for their lush, dark green appearance.
  • The Black Beauty Seed Mixture was created specifically to grow in sandy or clay like soils, and it will grow well in both partial and full shade.


  • Some users reported that it took up to two weeks before new grass growth was seen.


The Jonathan Green 10322 Black Beauty Ultra Grass Seed Mix is specifically formulated for damaged lawns that have clay-like or sandy soil. The addition of frontier perennial ryegrass seed to the list of ingredients ensures that the grass seed will germinate more quickly than its competitors. The Blue-Tastic Kentucky Bluegrass is ideal for filling in damaged areas of your lawn. Each of the grass seed included in this mixture has been carefully selected for the beautiful, lush green grass it produces.

This grass seed mixture contains seed that is naturally resistant to insects. One unique feature of these grasses is the fact that they feature an invisible waxy coating that wards off disease. This same waxy coating protects the growing grass in times of drought by preserving moisture within the leaf.

Although this review focuses on the seven pound bag of Jonathan Green 10322 Black Beauty Ultra Grass Seed Mix, it is also available in 1lb, 3lb, and 25lb options. The seven pound bag is advertised as covering up to 2,800 square feet; however, buyers should be aware that this measurement applies only if the lawn in question is being reseeded. For lawns that are being seeded for the first time, it will adequately cover approximately 1,400 feet of soil.

In order to enjoy the best results from the seed mix, the manufacturer recommends not using any chemicals to kill weeds in your lawn for a month before seeding and for six weeks after seeding. The use of chemical fertilizers should also be avoided for a minimum of six weeks after seeding, as the synthetic chemicals can essentially “drown” seedling grass. When mowing newly sprouted grass, you should use sharp blades at the mower’s lowest setting. Doing so avoids ripping out the new grass by the root.

User reviews for the Black Beauty seed mix have been mixed to positive. At the time of this writing, over 65% of users have rated it four stars or higher. There have been a number of complaints reported in which users said that the seed failed to germinate and produce any grass, or if it did, the growth was very slow. It should be noted that it is hard to determine if these complaints can be attributed directly to the seed mix as there are many variations in the types of lawns that the seed was planted in and in the quality of care the seed grass received.

Overall, the Jonathan Green 10322 Black Beauty Ultra Grass Seed Mix is a bit of a crapshoot. There are many types of factors, like the soil in your lawn, that will affect how effective this grass seed is; however, the majority of consumers are satisfied with its performance. It often takes a certain amount of trial and error to achieve the type of lush green lawn that all homeowners envy, but the Black Beauty seed mix offers an excellent starting point to begin with.
