bred to withstand environmental stresses over a wide geographic area and can be considered
“environmentally tolerant.” Of particular delight to homeowners and
professionals is Rugby’s ability to provided high quality turf even at both
low-moderate fertility levels and limited moisture.
Rugby has
good disease resistance to Leaf spot, Powdery Mildew, Dollar Spot, Stem Rust, and Fusarium
Blight. It maintains a medium-dark green texture even under low-moderate nitrogen and
water inputs. Rugby is an excellent variety to blend with other bluegrasses, perennial
ryegrass, fine fescues and tall fescue.
