Dealing with Shady Sites
Lawn Grass Options
Having a quality lawn in the shade can be a challenge. Lawns in shade areas are typically thin, weak, and of poor quality. In addition, lawns in shade areas generally do not have the ability to tolerate or recover from stress as compared to lawns growing in full sun. Start improving shade areas for grass growth by pruning trees and large shrubs as much as feasible to allow the maximum amount of light to reach the soil surface.
Significant shade such as this makes growing a quality lawn difficult.
Red fescue or other fine fescues are the primary lawn species in shade lawn mixtures. Among the more commonly used cultivars of the fine fescues are Jamestown, Banner, Barfalla, Checker, Highlight, Koket, Shadow (all chewings fescues); Dawson, Ensylva, Fortress, Pennlawn, and Ruby (creeping red fescues); and Aurora, Biljart(C-26), Reliant, Scaldis, and Waldina (hard fescues). Perennial ryegrass and tall fescue offer intermediate shade tolerance. Perennial ryegrass cultivars for shade include Birdie II, Citation II, Fiesta II, Manhatten II, Palmer,and Regal. Tall fescues best for shade include Falcon, Finelawn, Houndog, Jaguar, Olympic, Rebel,and Rebel II.Kentucky bluegrass generally does poor in the shade, but some shade tolerant cultivars include Bensun, Bristol, Eclipse, Glade, Nugget, Touchdown,and Victa.
After establishment, care of established lawns in shade areas is different than lawns located in full sun. Mow higher (near 3 inches), and fertilize less in the shade, as too much nitrogen can be detrimental to shade lawn species. About one to two pounds of actual nitrogen per 1,000 square feet per growing season is all that is needed. When watering shade lawns, do so as infrequently as possible, and water deeply. Reduce traffic over lawns in the shade.
Fine fescue and Kentucky bluegrass are used successfully on this shade
lawn.
If these practices have been followed but the lawn still fails, there probably is not enough light, even for a shade tolerant grass species. Shade tolerant grasses still need an acceptable amount of light to grow. Lawns in the shade often have problems with moss (discussion follows) or shade-loving broadleaf weeds (see Lesson 6-Weed Problems in Lawns). Ground ivy, or creeping charlie, is a prime example. These problems exist primarily because the lawn grasses are thin and weak, allowing easy invasion. Follow the steps outlined above to help avoid these problems. Another option is to try a shade tolerant groundcover, as discussed below.
