Scotts Turf Builder Grass Seed Perennial Ryegrass Mix Review

My Rating:

Ryegrass often has an unfair reputation because the fact that it is primarily an annual grass is mistaken for poor quality. In reality, ryegrass has many advantages to offer. For example, it assists with erosion control, efficiently recycles nutrients, and aids the soil in recovering nitrogen. In recent years, the introduction of perennial ryegrass has made this strain of grass seed a favorite among residential homeowners, and golf courses, along with schools and universities. The surface of this grass reflects light well, which gives it an attractive shine.

The Scotts Turf Builder Grass Seed – Perennial Ryegrass Mix is guaranteed to produce thicker and greener grass than its competitors – and to grow more quickly. A 7lb bag of this grass seed mixture will provide up to 2,900 square feet of coverage for reseeding and 875 square feet for new lawn coverage. Because of the properties of the ryegrass strain used in this mixture, this is Scotts recommended choice for homeowners whose lawns have compacted soil.

Read on to find out more about why Scotts Turf Builder Grass Seed – Perennial Ryegrass Mix has become one of the bestselling types of grass seed!


  • This grass seed works exceptionally well in compacted soil.
  • Each seed is coated with Scotts’ patented WaterSmart PLUS Coating to feed it essential nutrients and to protect it from disease.
  • The ryegrass used in this mixture has a high traffic tolerance.


  • For some users, the seed failed to germinate.
  • The bag does not contain seven pounds of grass seed.


The Scotts Turf Builder Grass Seed – Perennial Ryegrass Mix is specifically formulated for use on compacted soil. Not only does it grow quickly, but the perennial ryegrass seed chosen for this mixture holds up well in high traffic areas – making it the preferred choice of schools, universities, and other similar facilities. Perennial ryegrass is well-known for its ability to assist in erosion control, and its lush, dark green hue is aesthetically pleasing.

One of the standout features of this grass seed is Scotts’ patented WaterSmart coating. This specialized coating protects the seeds from diseases and insects. It is also designed to jumpstart their growth. When compared to untreated seeds, seeds equipped with this technology absorb twice as much water and nutrients. This prevents the seeds from drying out – even if they are not watered for a day or two as recommended by Scotts. It also provides the coated grass seed with essential nutrients that allow them to grow faster than untreated seeds.

The best time to plant Scotts Turf Builder Grass Seed – Perennial Ryegrass Mix is when the temperatures are between 60 and 80 degrees. For most regions, this will be around Labor Day. Perennial ryegrass is a cool season grass, and it grows best under these conditions. The cooler weather allows the new grass time to develop a strong root base before the cold weather sets in. Alternately, this grass seed can also be planted in early spring because of the heavier rainfalls and cooler temperatures.

The ryegrass seed used in this mixture will, on average, begin to germinate approximately five to ten days after being planted; however, depending on seasonal conditions, it can take 30 to 60 days before the grass fully matures. In order for the grass to grow, it must be watered on a daily basis. The experts at Scotts recommend watering new grass seed once a day until the grass reaches a minimum height of two inches.

A single 7lb bag of Scotts Turf Builder Grass Seed – Perennial Ryegrass Mix will provide 875 square feet of coverage for newly seeded lawns and up to 2,900 square feet of coverage for lawns that are being reseeded. Newly planted grass seed will need to be fertilized according to the manufacturer’s instructions.


By and large, reviews for Scotts Turf Builder Grass Seed – Perennial Ryegrass Mix have been positive. At the time of this writing, 67% of reviewers on Amazon had rated this grass seed mixture four stars or higher (out of five). For a small percentage of users, the grass seed failed to germinate. A handful of reviewers were dissatisfied that 49% of the bag’s overall weight was due to the seed coating, rather than providing a full 7lbs of grass seed.

Despite these minor complaints, those who have used this perennial ryegrass mixture have praised its growing power and the beauty of the mature grass. So long as the manufacturer’s instructions are carefully followed, this product seems like a solid investment.
