X-Seed Ultra Premium Quick and Thick Lawn Seed Mixture Review

My Rating:

A healthy, lush green lawn has much more to offer than just good looks. When it is in excellent shape, your lawn benefits the soil by acting as a natural barrier to erosion, building ideal climates for microscopic creatures to live, and by contributing to organic soil matter. In addition to boosting your home’s curb appeal, a healthy lawn functions as a natural air conditioner by cooling the around your home (thereby reducing your home’s energy consumption), and it reduces urban noise pollution by naturally absorbing sounds.

If your lawn is brown, balding, or bare, it’s time to ask for assistance.

Enter X-Seed Ultra Premium Quick and Thick Lawn Seed Mixture.

This new grass seed mixture offers a revolutionary method of seeding a new lawn or repairing bare patches with a minimal amount of effort. In addition to premium grass seed, this mixture also includes a professional grade fertilizer. The ingredients in the X-Seed Ultra Premium Quick and Thick Lawn Seed Mixture eliminate the need to lay down mulch on top of your new grass seed. The seed will begin to germinate in as little as 5 to 7 days and produces a rich, dark green hue.


  • Each bag of seed mixture is guaranteed to be 99.9% free of weeds.
  • The manufacturer does offer a satisfaction guarantee on each bag of seed that is sold.
  • Buyers have praised the promptness and helpfulness of X-Seed’s customer support team.


  • The price tag is expensive.
  • This seed mixture does not cover as much new lawn as its competitors do.


  • This seed mixture will grow well in both sun and shade conditions.
  • It is created for use in Northern parts of the United States.
  • The mixture uses perennial grass seed, so there is no need to replant year after year.
  • For new lawns, a 20lb bag will cover approximately 7,000 square feet.


The X-Seed Ultra Premium Quick and Thick Lawn Seed Mixture is designed to enable residential homeowners to achieve the beautiful, healthy lawn they have always wanted with a minimal amount of effort. The seed composition of this mixture includes the following:

  • 55% Perennial Ryegrass
  • 30% Fine Fescue
  • 15% Improved Kentucky Bluegrass
  • 4% Inert Soil Matter
  • ~1% of Filler

Each bag of X-Seed grass is guaranteed to be 99.9% free of weeds.

What makes this grass seed unique is that each bag is actually a mixture of premium grass seed and fertilizer. However, rather than using traditional paper mulch, this grass seed mixture contains coir. This non-traditional type of fertilizer is made from compressed blocks of coconut pith. When water is added to it, the coir will expand to four times its original size. The coir increases the ability of the seed (and the soil around it) to retain water, which ensures that the seed receives the moisture it requires to grow. X-Seed has also added Moisture Boost Plus Crystals to aid in water retention and reduce the need to water the new grass seed by as much as 50%.

While these additions can be helpful under the right circumstances, many buyers have struggled to figure out how often to water their new grass seed. Naturally, if it is watered too little, the grass will die; however, a few buyers have over-watered their seed, which has essentially “drowned” it. Reviewers have reported that X-Seed’s customer service staff have been excellent about answering questions and providing assistance when needed.

Because of the ingredients included in X-Seed Ultra Premium Quick and Thick Lawn Seed Mixture, X-Seed states that no soil tilling or preparation is required before laying down this grass seed. The seed can be dispensed with a handheld shaker bag or a drop spreader. After spreading, the seed will need to be raked and watered, but that is the extent of the effort required.

For new lawns, a 20lb bag of X-Seed Quick and Thick Lawn will seed approximately 7,000 square feet of lawn. For established lawns, the same 20lb bag will cover roughly 14,000 square feet.
