Jonathan Green Fast Grow Grass Seed Mixture Review

My Rating:

The Jonathan Green brand is a family owned business that was originally established in 1868 by its namesake founder. Today, the label brings five generations of expertise to the table, and they are committed to providing organic garden and lawn solutions that improve their clients’ soil and make it more welcoming to grass, vegetables, and flowers. Each of their products is eco-friendly and are specifically formulated to be friendly towards children and pets.

One of the newest additions to their product line is the Jonathan Green Fast Grow Grass Seed Mixture, and it contains seeds that are carefully chosen for their ability to provide a hardy turf for families quickly. This mixture will germinate in as little as seven to fourteen days. This product can be purchased in 3lb, 7lb, 15lb, and 25lb bag sizes.

The seed composition for this mixture is as follows:

  • 59.10% Annual Ryegrass
  • 19.65% Perennial Ryegrass

  • 9.80% Kentucky Bluegrass
  • 1.55% Inert Matter

Ryegrass, which comprises the majority of this seed mixture, is naturally drought resistant, and because it is a quick growing ground cover, it also offers excellent erosion control. Because it germinates and matures quickly, it is a great natural suppressor for weeds.

The Jonathan Green Fast Grow Grass Seed Mixture is one of the highest rated seed grass mixtures on Amazon. At the time of this writing, 75% of reviewers have given it a four star (or higher) rating. When fast results are required, this is the seed mixture that homeowners turn to. Each seed included in the mixture was selected for its fast growing capabilities and its natural resistance to insects. On average, it will take 7 to 14 days for this grass seed to germinate and begin to sprout. The hardiness of the grass seed ensures that it will grow well in all types of conditions, including shade and sun.

The primary ingredients used in this grass seed mixture are an annual ryegrass and a perennial ryegrass. Ryegrass is a hardy, quick growing type of grass that offers a number of benefits, but its being used as the main ingredient in this mixture has caused a handful of complaints among users.

The annual ryegrass will germinate, grow, and provide ground cover for roughly a year, but then it begins to significantly thin out. As a result, the ground must be reseeded each year, and this has caused some complaints among reviewers. By comparison, the perennial ryegrass grows well in the shade, but some users have felt that there was not enough perennial ryegrass used in the mixture to provide adequate cover for the bare, shady areas of their yards.

With that being said, the high approval rating of Jonathan Green Fast Grow Grass Seed Mixture is a testament to its quality.

Would this grass seed mix well with Michigan bluegrass seed? We planted Michigan bluegrass seed a week ago not realizing the germination time is so long. Would it be a good idea to oversees it with something like this? We live in Central Nebraska.
