Best Grass for Shade: Shade Tolerant Grass Varieties for Low Light Lawns

Is your lawn grass assuming a spindly, weak, and discolored appearance that’s visually unappealing? Do you have trees or nearby building structures shading parts or the whole of your lawn area? If your answer to both of these questions is ‘yes’, then, you’re most likely dealing with a case of poor plant health due to low-light conditions.

Sunlight- just like air and water- is one of the natural resources that support the growth of grass. Insufficient sunlight exposure can lead to unhealthy lawn grass that lacks the characteristic lush, green appearance. Shaded lawns- therefore- present a growth challenge for most turf-grass varieties; regardless of whether the shade is coming from trees and shrubs growing on the lawn, or from nearby structures causing partial shading.

Fortunately, for homeowners, there exist a variety of shade-tolerant turf-grass varieties that do better in low-light conditions, provided that additional stressors are kept at bay. In this blog, we’ll look at five shade-tolerant grass varieties that you can choose from when looking to plant grass on your shaded lawn.

What grass grows in shade?

  1. Zoysia Grass

Zoysia is a great warm-season turf-grass for partially-shaded lawns. Requiring only about three hours of direct sunlight per day to grow and maintain its deep green turf color, this turf-grass variety is more shade-tolerant than cool-season alternatives like Fescues and Ryegrass. However, it’s still not as prolific at thriving in the shade as St. Augustine grass.

Fine-blade varieties like Zeon and Geo Zoysia have proven to be the most shade-tolerant Zoysia grass varieties. Apart from withstanding the shade, Geo Zoysia will also thrive even when faced with additional stressors like heavy foot traffic.

  1. Fescue

Fescue is a cool-season grass variety that can withstand lightly-shaded areas, but won’t thrive under dense shading. Some sub-varieties- like Tall Fescue- have additionally adapted to thrive under conditions of low soil nutrient. This is an important advantage because many grasses growing under tree-shades tend to die due to having to compete for minimal soil nitrogen with the roots of these trees. If you’re planning to grow Fescue on your shaded lawn, you’ll have to ensure it gets at least four hours of dappled or filtered sunlight exposure per day.

  1. St. Augustine Grass

St. Augustine’s minimal direct sunlight requirements (in comparison to similar warm-season turf-grasses like Bermuda grass) is what makes this turf-grass variety the preferred option for shaded lawns. However, not all St. Augustine grass varieties will thrive under conditions of prolonged sunlight deprivation. The Floratam sub-variety, for instance, requires averagely seven hours of direct sunlight per day to grow and stay healthy. Specific St. Augustine Grass sub-varieties that are highly shade-tolerant include Palmetto, Sapphire, and Seville. These varieties only require four hours of daily, direct exposure to sunlight to thrive. Still, they are best-reserved for partially-shaded lawns, as they may struggle to thrive in lawns that are deeply shaded.

  1. Rough Bluegrass

This bluegrass variety is the most-adapted to shady, cool, and wet conditions, making it great for shaded lawns in colder regions. Rough Bluegrass doesn’t even need direct sunlight exposure at all, as it requires just over four hours of dappled sunlight per day to thrive. By comparison, Kentucky bluegrass can also grow in shaded lawns- especially if planted via seed; but can’t cope without some hours of daily, direct sunlight exposure.

  • Perennial Ryegrass

This shade-tolerant Ryegrass variety needs minimal sunlight exposure in order to thrive, unlike many other Ryegrass varieties that don’t cope well in shaded areas. Perennial Ryegrass cultivar only requires about five hours of direct sunlight exposure per day. However, filtered or dappled sunlight is likely to hamper growth due to the total lack of exposure to direct sunlight.

Also, this cultivar does well in soil temperatures between 65-80 degrees Fahrenheit, but will struggle if soil temperatures exceed 85-degrees Fahrenheit. However, if you keep your soil adequately watered during the warmer summer days, your Perennial Ryegrass may maintain its healthy, lush appearance.

What southern grass grows in shade?

If you live in the Southern states, choosing the most appropriate shade-tolerant grass variety to grow in your lawn calls for the consideration of multiple factors, including: the soil type, the surrounding environment, the region’s climate, sunlight conditions, and amount and frequency of rainfall.

This- therefore- means that the most suitable grass varieties for the Southern-most states (like Florida and Texas) may not be the most suitable for Southern lawns located a bit further up (like in Virginia and North Carolina). For instance, Zoysia grass and St. Augustine turf-grass varieties are more likely to thrive in sunny and warm Florida than in the moderately warm Tennessee/Virginia region. Fine Fescues, meanwhile, would do better in shaded-lawns in Virginia.

Below, we take a look at how various factors should affect your decision-making when picking a shade-tolerant turf-grass for your Southern lawn:

  1. Appearance

For a shaded lawn in the South, your best chance at achieving aesthetic appeal is to pick a grass type whose natural appearance masks the stresses caused by the low-light conditions. A suitable grass type should have wide blades, a thick growth pattern, and striking coloration. One warm-season grass variety that bears all three of these characteristics is St. Augustine grass.

  1. Climate Conditions

In Virginia and Tennessee, considered as the upper South, the climate is not as warm as in the Southern-most states; and temperatures sometimes drop to very low levels. Add some shade to the equation- and what you have is a rather unfriendly growth environment for warm-season turf-grass varieties like Zoysia. Instead, go for a cold-season turf-grass variety like Fine Fescue.

  1. Soil Conditions

Across the South, most soil types have good drainage properties, making lawns in the region great for growing water-sensitive grass varieties like Zoysia and St. Augustine grass that tend to suffer from drought whenever the soil is overwatered due to frequent rainfalls and poor soil drainage.

How to make grass to grow in shade under trees

The excessive shade provided by trees normally hampers the growth of most turf-grass varieties. What’s more, trees tend to make use of most of the moisture and nutrients in your lawn soil, leaving little for grass to thrive on. This, however, doesn’t mean that you can’t successfully grow grass beneath a tree-shaded lawn area. Planting any of the shade-tolerant turf-grass varieties discussed above will set you on the path to success. To ensure your tree-shaded grass grows fast and stays healthy, consider the following purchasing, planting, and maintenance tips:

  1. When you’re making purchase decisions on a suitable shade-tolerant grass variety, consider one that is adapted to your specific geographic region. You can find credible information about turf-grass adaptability to specific climatic regions from various internet sources.
  2. When planting grass beneath very large trees like oaks and figs that provide excessive shading, consider pruning some of the foliage. This will open up spaces through the overhead canopy, allowing for more sunlight to reach the growing grass below. Remember, climbing large trees while pruning presents a significant safety risk as you may fall, which is why you should also consider hiring a landscaping professional to get the job safely done.
  3. When looking to feed your tree-shaded grass after planting, avoid applying commercial fertilizer, as grass growing in shaded areas typically requires less nitrogen nutrients in comparison to grass growing under direct sunlight exposure. Instead, apply slow-release organic compost, which you don’t even have to buy; as the internet is filled with lots of informative tips on backyard composting.
  4. Another maintenance tip to aid the growth and health of your tree-shaded grass is to minimize/keep off any stressors. These may include food traffic, herbicides, and pet urine.
  5. Mowing appropriately will also help your tree-shaded grass to thrive. This includes mowing at about one-inch taller than you would grass grown under direct sunlight; since the extra grass blade surface area allows for intake of more sunlight, in conditions where this resource is scarce.
  6. The final maintenance requirement to aid the growth of grass grown under tree-shades is to water often, more than you would a lawn that’s exposed to direct sunlight. This is because most of the rain is blocked from reaching the ground by the trees’ leaves. What’s more, the grass is still usually left to compete for whatever little rainwater reaches the soil with the roots of the trees.
