Shaded areas normally yield a thinning lawn, bare spots, and slow growth of grass. Areas in your lawn that have a dense shade due to tall trees and buildings can be difficult to get grass growing in them. The best solution is to plant good grass that grows in shade.
The best shade tolerant grass to choose from include St. Augustine grass and Zoysia (warm-season grass). Cool-season grass types for low light conditions would be Ryegrass, tall fescue, and fine fescue. Instead of planting just one species, you could also choose to mix grass seed to get a sun and shade balance.

Best Shade Tolerant Grass
When establishing a new lawn – using grass seed, sod, or hydroseed – shade is sunlight conditions are a major factor. Some lawn grass types do well in full sunlight while others can withstand shade and thrive.
Tall trees and buildings near your yard are a clear sign there will be some sort of shade covering your lawn for a considerable amount of time per day. Therefore, it is very important to know the sunlight requirements for different lawn grasses to guide you in choosing the right species to plant.
Here are the best shade resistant grasses to grow in a lawn with low light conditions:
1. St. Augustine Grass
St. Augustine grass is a warm-season lawn grass that is known to do well in shaded areas. This does not mean that it will always thrive in long, deep-shaded areas. It still has some sunlight requirements although not as long exposures as other options like Bermuda grass. (See my detailed guide on how to choose between St. Augustine and Bermuda grass here.)
There are some cultivars of St. Augustine grass that are highly resistant to shade. These include Sapphire, Bitter Blue, Palmetto, and Seville. These cultivars also thrive well in full sunlight. 4 – 5 hours of direct sunlight is enough, making them the best grass to grow in partially low sunlight conditions.
St. Augustine Grass Sunlight Requirements
The most common cultivar of St. Augustine grass is Floratam. It is widely found in the southern United States. However, it is not the most shade-resistant type to grow for such adverse conditions.
- Floratam requires at least 6 – 8 hours of direct sunlight to thrive well.
- Palmetto, Seville, and Sapphire cultivars require a minimum of 4 – 5 hours of direct sunlight per day.
Deprivation of light can show problematic symptoms such as thinning, disease attack, and stunted growth.
If your lawn is under a full shade, I still wouldn’t recommend growing any of these turfgrasses. You can, however, improve the survival ability of St. Augustine grass by cutting canopy above the lawn to allow a good amount of sunlight to penetrate underneath.
2. Zoysia Grass
You can grow Zoysiagrass as a shade-tolerant species. However, it still prefers sun and we cannot say that it is a shade-loving grass. Its low-light tolerance is better than that of Bermuda grass, so between the two, it would be the right pick. You can successfully grow Zoysia in subtropical areas, such as Florida.
Zoysia sunlight requirements
Being a warm-season turfgrass, Zoysia will require at least 3 – 4 hours of direct sunshine to thrive really well. This makes it a great choice for lawns with partial shade – such as those near tall buildings and distant tall trees.

Many sources recommend Zoysia cultivars with fine blades as the best shade-tolerant turfgrasses. A great fine-bladed Zoysia variety that is extremely shade-tolerant is Zeon. It is usually planted on golf courses and sports fields. Another fine-bladed shade-loving grass you can choose is Geo Zoysia. It produces a deep green turf that’s tolerant to wear and foot stress.
Some cultivars such as Emerald Zoysia may not be the best for long hours of shade because they grow very slowly and can be chocked out by aggressive weeds such as crabgrass.
Zoysia does not tolerate shade as well as St. Augustine grass, but it is better at surviving low sunlight conditions compared to Fescues and Rye.
Fescue is a great grass that grows in shade but that does not mean it will thrive well in densely shaded areas such as those with dogwoods. However, if you’re looking for a cool-season grass for shade, tall fescue would be excellent to plant in your lawn.
Turf-type tall fescue is shade-tolerant and can also grow well in drought conditions as well as low-fertility regions. It is, however, worth noting that even though fescue grass is shade-resistant to some extent, it still prefers full sun for optimum growth and coverage.
Fescue sunlight requirements
Fescues require 4 – 6 hours of filtered or dappled sunlight for healthy growth. However, even this alone may not be enough to make it grow well near trees. Ensure proper care, such as mowing higher, watering adequately whenever the ground is dry and applying moderate amounts of nitrogen fertilizers to give fescue grass a better chance of surviving low sunlight conditions.
If you do not want to grow tall fescue, you can opt for red fescue, fine fescue, or Chewings fescue which are good cool-season types.
Fine fescue is commonly grown in the central and north United States. The fine blades of this turfgrass make it suitable for growing in shady areas.

4. Rye Grass
Not all varieties of Ryegrass tolerate shady areas very well. The highly recommended grass type here for low sunlight conditions is Perennial Ryegrass. This cultivar does not require extensive hours of direct sunlight like other varieties.
Sunlight requirements for Perennial Ryegrass
- Plant ryegrass if your lawn will receive at least 4 – 5 hours of direct sunlight.
- If your lawn has filtered sunshine or dappled daylight perennial ryegrass will not thrive well.
Remember that rye is a cool-season turfgrass and will prefer climates where temperatures remain between 68 and 77 degrees Fahrenheit. It’s shade tolerance persists even in summer if there’s a little moisture on the lawn.
It is not uncommon to find ryegrass dying in the summer when temperatures are scorching – soil temperatures above 90 degrees.
The particular variety of bluegrass that’s excellent for shade is rough bluegrass. Rough bluegrass is best adapted to wet, cool, and shady areas. If you’re planting a lawn in hot temperatures, you might want to skip rough bluegrass because during summer, it dies off leaving bare spots in your lawn.

Rough bluegrass is aggressive in shady areas especially under trees so long as the climate is cool and the soil moist. It requires about 4 hours of dappled sunlight daily to thrive.
When discussing bluegrass, it is hard to leave out Kentucky Bluegrass. It is a great option for cool-season lawns. Kentucky Bluegrass seed lawns can still grow well in partial shade but will still require some amount of direct sunlight.
Is There a Full Shade Grass Species?
When shopping for grass seed, it is important to choose a shade-tolerant species that is well adapted for your region. Grass seed that’s adapted for Texas may not do well when planted in regions far from such environs.
On this list, the most shade tolerant grass can survive with barely 4 hours of direct or dappled sunlight. So, is there something like a full-shade grass species?
It is not possible to find full-shade grass seed because all plants require sunlight for photosynthesis. If the area in your yard where you want to establish a lawn is fully covered with shade, prune the branches of trees to allow penetration of some sunlight beneath. It will allow your grass to grow and thrive better.
How to Get Grass to Grow in Shade
Although the grass species and cultivars we’ve discussed above can grow under trees and low light conditions, it is important to observe a few care tips. These will help your grass grow fast, thicker, and fuller.
Any turfgrass with high shade tolerance still requires diligent care to flourish. Take for example areas where grass grows under trees. It will have to compete with the roots of those trees for nutrients, oxygen, and water.
Here are tips on how to get grass to grow better in areas with shade:
- Reduce stress on the grass – minimize foot traffic in areas of your lawn that receive less sunlight per day.
- Increase the mowing height – Mow your grass higher than you normally would to allow more surface area on the grass blades for maximum absorption of the limited sunlight.
- Treat lawn diseases promptly – Exposure to long hours of shade means your lawn remains wet for long during the cool seasons. This leaves your lawn prone to fungal diseases. Pay extra attention to the signs on the grass under low-light conditions and treat any diseases as soon as you notice them.
- Seed or overseed each fall – Overseeding heavily will help your turfgrass grow denser than weeds. I would recommend you overseed with 6 – 8 lbs of grass seed per 1000 square feet to achieve a great cover in low light conditions.
- Plant a dense shade mix grass seed – Even if your lawn receives dappled sunlight each day, one of the best ways to get grass to grow in shade is to use a shade mix grass seed.
A mix of shade-tolerant variety and self-repairing grasses can keep your shaded areas well covered. A good example is the Scotts Turf Builder Grass Seed Dense Shade Mix which does well under trees with as little as 3 hours of direct sunlight per day.
Other than observing the above tips for growing a dense cover of turfgrass in shady areas of your lawn, remember to get rid of stubborn weeds such as crabgrass and quackgrass to prevent them from choking out your preferred grass.
Also, feed grass in shaded areas a little more than the areas with full sun. The reason for this is that the competition for nutrients is higher in this area and standard feed amounts may not be enough to grow a thick lawn under shade.
Tall and Ornamental Alternatives
When normal turfgrass fails or becomes tough to maintain in shady areas, you can choose to plant tall and ornamental grasses. These are basically used for decorative purposes and can keep away the ugly bare spots in areas of your lawn that are covered with shade.
Some of the best ornamental grasses for shade include:
- Japanese forest grass
- Blue grama grass
- Korean feather reed grass.
- Autumn moor grass.
- Fall blooming reed grass.
- Little Miss maiden grass
Most of these grow fast, forming beautiful arching clumps with foliage. The leaves are sometimes variegated. The foliage coloration is what makes these grasses a great choice for decorating shady areas of your lawn.
