Homeowners choose zoysia for 3 main reasons:
- Drought Resistance
- Forms a dense turf
- Tolerates traffic well
Zoysia grass is a hearty and durable grass that features a beautiful light green color. It is a warm-season grass that thrives in regions with high heat and humidity. Zoysia grass is also drought-tolerant and accommodates moderate amounts of traffic.
It has the following advantages over other warm season grasses:
- Very low maintenance
- Stays green during times of drought
Zoysia's drought-tolerance is attributed to it's dense turf keeps its roots relatively cool. This helps the grass retain its moisture. Its aggressive, deep root system means it can still draw moisture from the soil when other species begin to fail.
Many experts refer to it as a transitional zone grass. Transitional zone grasses thrive in areas too warm for cool-season grasses and too cold for warm-season grasses. Imported from Asia in the late 1800s, it quickly turned into a preferred grass for homeowners.

Less Green Than Other Grasses
Although, it’s a dense turfgrass, Zoysia is not a real vibrant green color but stays a light or medium green during the growing season, turning brown during the dormant winter months. As a warm season grass Zoysia greens up in mid-to late spring when warm temperatures trigger its growth state, actively growing until late into autumn when temperatures begin to fall.
However, Zoysia will stay green longer than other warm season grasses such as the popular Bermudagrass or other varieties. Some homeowners choose a companion planting of ryegrass to achieve a four-season green turf.
Ideal Conditions for an Optimal Zoysia Lawn
Zoysia grass is a warm-season turf and thrives in temperatures above 75 degrees. Several days of sustained temperatures above 70 degrees will kick-off its growing season.
If you live in an area where the temperature does not suit St. Augustine, Centipede, or Bermuda grasses, Zoysia may be a better option. It can tolerate temperatures that are much lower than other warm-season grasses. It can withstand heat and moderate cold snaps. This makes it perfect for transitional zones.
Once temperatures dive below 55 degrees for a few days, Zoysia grass will brown and lose its green color. The grass is not dead; it is entering dormancy. Zoysia has a more pronounced discoloration than other warm-season grasses. Zoysia's winter appearance will disappoint homeowners desiring year-round green grass.
Zoysia lawns should receive anywhere between four and six hours of direct sunlight a day. Shady areas may not see rapid growth or spreading. However, Zoysia under shade will perform better than will Bermuda grass or Centipede.
A Zoysia lawn should receive between 1 and 1.25 inches of water every week, low relative to other grasses. If the grass does not receive enough water, it will begin to turn brown. The grass will quickly regain its color after receiving water.
Zoysia Grass Withstands Moderate Traffic
Another huge advantage with Zoysia is its ability to tolerate very high traffic which makes it a great choice for families who spend more time on lawn activities. Zoysia will stand up even to the daily use by highly active, outdoor children who can wear a lawn out very quickly. Zoysia lawns can quickly recover from traffic or stress if adequately watered.
Zoysia Establishment & Growth
You can establish a zoysia lawn with seed or sod. Establishing a lawn with sod provides the fastest results but is more expensive. Establishing a lawn with zoysia seed is slower but is more cost effective.
Zoysia spreads by stolons that creep across your lawn. Stolons creep away from established grass and plant roots as they make their journey. Zoysia’s stolons grow at a very slow rate but are heartier than other varieties.
Slow growth and deep roots makes the grass hardy and resistant to drought and extreme temperatures. Zoysia is not a good choice if you need to cover a large area in a short amount of time.
Zoysia grass blades are notoriously tough and wiry. You'll have to sharpen lawnmower blades frequently when servicing a Zoysia lawn. If edges are not kept sharp, damage to the grass can occur.
How to Fertilize your Lawn
Zoysia lawns need three to four pounds of Nitrogen per growing season. Potassium enrichment also contributes to the grass’s heartiness and drought resistance. Always use a 15-0-15, 15-0-10, 15-0-5 fertilizer unless a soil test indicates otherwise.

Zoysia Grass Maintenance Schedule
January – April
Applying a pre-emergent herbicide to the lawn in late February or early March will give a Zoysia lawn protection against a host of weeds. After using the pre-emergent:
- Reapply the same product in two months for maximum effectiveness.
- If the lawn already has existing weeds, apply a post-emergent herbicide at his time.
- If insect damage is visible, apply an insecticide. Infestations will worsen in the coming warm seasons.
- Overseed bare or thin areas before the grass enters its growing season.
Early Spring is an excellent time to check the pH level of the soil. It thrives in soil with a pH level between 6 and 7. If you find that your lawn is outside of the preferred range, you can find tips to correct the problem here.
If you need to adjust the pH, apply the correcting nutrient with the first round of fertilizer.
- May: Apply .5 to 1 pound of nitrogen fertilizer, along with any herbicides or pH balancing nutrients.
- June-July: Apply .5 to 1 pound of nitrogen fertilizer, along with any post-emergent herbicides.
- August: Apply .5 to 1 pound of nitrogen fertilizer.
Potassium is critical to prepare Zoysia grass for the coming winter. Potassium aids in the ability to fight off cold weather diseases and insect attacks.
September – December
Ensure that the Zoysia grass is continuing to receive adequate water amounts. While the grass is dormant in the winter months, it will need 1″ every 1.5 to 2 weeks.
Fertilization is not recommended in the winter months. Apply a pre-emergent herbicide to prevent any weeds from growing now. If the soil needs a pH correction, apply the appropriate products at this time.
