"Rhizomatous Tall Fescue (RTF) is a new type of tall fescue, which produces rhizomes. A rhizome is a creeping stem or runner that extends outward from the main plant underground. The rhizome will send a shoot up to the soil surface while extending new roots downward, forming a new plant. RTF behaves like a bluegrass, but like any other fescue it will survive the transition zone. The only seed you'll ever need!" - a quote from the RTF website: www.aboutrtf.com Curious about this product - has anybody tried their seed or sod? Sounds like a "too good to be true" product. Also sounds like it could end overseeding.........at first that sounds bad..........but progressive technology doesn't necessarily mean the loss of jobs or services; technology often creates new jobs and services that never would have existed otherwise......................... Would like to hear some pros and cons about this product.
