Zenith Zoysia Grass Seed 100% Pure Seed Review

My Rating:

Zenith is a relatively new variety of Zoysia grass. This "synthetic" seed is the result of a combination of 3 selected parent clones. Through cross-pollination, this grass, first sold in 1990, should inherit desirable traits including better color and resistance to insects, drought, and disease. It has blades comparable in width to many Bluegrasses, Centipede, and a few Rye grasses. It looks very similar to Meyer Zoysia (Z-52). Tests have shown that Zenith Zoysia produces a better quality turf than Zoysia seed that has been imported. This grass seed was produced by the Patten Seed Company.

Zoysia can produce an established, fully covered lawn in as little as 6 months IF the following directions are adhered to. Zoysia seeds must be planted either in late Spring or in Summer. One to two pounds of Zenith Zoysia Grass Seeds per 1,000 square feet is required. Plant on grass free, weed free, prepared soil. Use approximately 1/8" soil cover, so that good soil to seed contact is made. Don't plant in the Fall or with Ryegrass. Mow the area regularly to keep it shade free. Water once or twice a day (in the morning and the afternoon) for the first 15 to 25 days until the first seedlings sprout, then switch to every other day. When it rains you can skip watering. Water as needed after the first 8 to 10 weeks.


  • Grows amazingly well in very hot weather
  • Produces a superior golf course tee, rough, or fairway
  • Low nutrition and water required
  • Once Zoysia is established it should choke out many weeds


  • Not good for overseeding on established lawns
  • Harder to mow with rotary mower compared to cool weather grasses
  • Should be planted on level ground 


  • Creates a dark green very dense lawn
  • Hardy and drought tolerant in both extreme cold and heat
  • These seeds are non-GMO, don't contain filler, and they have an excellent germination rate


Zenith Zoysia belongs to the Japonica family, just like Meyer Zoysia, and bears many similarities to Meyer Zoysia, like color and blade width. Zenith is a bit less dense, allowing later interseeding using tall fescue. Like other Zoysias, it spreads slowly, so 1-3 pounds every 1,000 square feet is the recommended seeding rate.

Zoysia seed has been (pre-treated) in order to improve germination speed and percentage. Like other pre-treated seeds, Zenith Zoysia must be planted in the same season, and storage is not recommended. If you must store, it should be in a dry, cool area. Occasionally Zoysia turf may suffer minor damage from leaf rust or Large Brown Patch, or from insect pests including mole crickets, bill bugs, and grubs. For the most part, well-maintained Zoysia grass is tolerant or resistant to the majority of turf and insect diseases. This is an environmentally friendly grass.

Seeded Zoysia grass becomes dormant during Wintertime and turns golden brown until the warmer temperatures come back in the Spring.

Zenith Zoysia is a slow growing grass but can result in a beautiful, long-lasting lawn if conditions are right. Its texture is intermediate, its shade tolerance is good, and its soil preference is loam or clay. This grass should be mowed frequently to maintain its appearance. Mow every 7 to 14 days at low fertility, and 1 to 2 times a week if the yard is overly fertilized. A broadcast or drop spreader is recommended to spread Zoysia seeds evenly. Broadcast seeds should be dragged or raked lightly, using a lawn roller for insurance of good soil to seed contact. Don't bury seeds deeper than 1/4" deep. If these seeds are planted too deep no germination could result.

Apply fertilizer at 4, 8, and 12 weeks. Do not use a fertilizer that is high in nitrogen in late Autumn. If possible, mow any lower areas using a reel mower. A rotary mower is good at higher levels. Start mowing at approximately 2" height whenever weeds or grass are ready to be cut. Use the sharpest mower blades for the finest result. Zenith Zoysia produces a tough grass that will need a clean cut for the sake of appearances. Zoysia seed should not be planted if pre-emergent herbicide has been used within the last 60 days. Herbicides shouldn't be used at all until approximately 12 week's growth has occurred.

    Hi Mark,

    When you say the seed is “primed” you are correct in saying it needs to be planted that season or stored correctly but this seed is not actually primed. It is pretreated with potassium nitrate, which is a chemical scarification treatment to help overcome dormancy issues and increase germination percent. Primed seed is a physiological treatment and involves hydrating the seed with a controlled imbibition (http://seedbiology.de/seedtechnology.asp). I am not aware of Patten seed using priming on their commercially available seed as osmotic priming does not perform well on small seeded plant species and solid matrix priming is a patented process that they do not have rights to.

      Thanks for pointing that out Alex, I changed the language.
