RTF Tall Fescue
The only tall fescue that repairs itself. True underground rhizomes fill in bare spots naturally — no overseeding, no clumping, no bare patches.
Why RTF Fescue?
RTF (Rhizomatous Tall Fescue) is a patented tall fescue developed by Barenbrug USA that solved the fundamental limitation of every other tall fescue on the market: the inability to self-repair. Traditional tall fescue is a bunch-type grass — when damage occurs from traffic, drought, disease, or pets, bare spots stay bare until you manually overseed. RTF changes that with true underground rhizomes that spread laterally through the soil, sending up new shoots to fill in damaged areas without human intervention. It uses 30% less water than standard cool-season grasses, handles both sun and shade, and thrives in Tennessee's transition zone where Kentucky bluegrass struggles with summer heat and bermudagrass can't survive winter cold.
Self-Repairing Rhizomes
The only tall fescue with true underground rhizomes. Bare spots from pet damage, foot traffic, or disease fill in naturally — no overseeding required. RTF plants produce up to 20x more rhizomes than any other spreading fescue.
30% Less Water
New Mexico State University trials proved RTF maintains turf quality with 30% less irrigation than standard cool-season grasses. Deep roots access moisture other grasses can't reach.
Transition Zone Champion
Engineered for states like Tennessee where summers are too hot for bluegrass and winters too cold for bermuda. RTF handles both extremes without browning or dying.
Endophyte Enhanced
Built-in beneficial endophytes deter chinch bugs, sod webworms, and billbugs while boosting drought recovery and disease resistance. Safe for pets and livestock.

RTF Fescue vs HGT Bluegrass
Choose RTF Fescue if...
You need a grass that thrives in Tennessee's summer heat without struggling. RTF handles transition zone heat far better than any Kentucky bluegrass, uses 30% less water, and tolerates more shade. Its self-repairing rhizomes eliminate overseeding entirely.
Choose HGT Bluegrass if...
You want the absolute finest blade texture and are willing to provide more water. HGT is the #1 NTEP-rated bluegrass for traffic recovery and has exceptional disease resistance — ideal for northern climates or heavily irrigated sports fields.
RTF Fescue vs Standard Tall Fescue
Choose RTF Fescue if...
You want a tall fescue that actually repairs itself. Standard tall fescue is a bunch-type grass — it clumps, leaves bare spots, and requires annual overseeding. RTF spreads via underground rhizomes, uses less water, resists weeds better, and maintains a smooth, uniform lawn without the maintenance cycle.
Choose Standard Tall Fescue if...
Budget is the only factor. Standard tall fescue costs less upfront, but the ongoing overseeding, weed control, and bare-spot repair costs add up quickly. RTF pays for itself over time.
Maintenance Guide
Mowing
Maintain at 2.5 to 3.0 inches year-round. Mow as needed, never removing more than one-third of the blade in a single mowing. Keep mower blades sharp — torn leaf tips brown and invite disease. Leave clippings on the lawn to recycle nutrients.
Watering
Established lawns need about 0.9 inches per week, delivered in 1–2 deep sessions. New sod requires 2–3 times daily for the first 4 weeks with light, frequent applications. Water early morning to reduce evaporation and disease pressure.
Fertilizing
4 applications per year: early spring, late spring, early fall, and late fall. Use a balanced formulation at label rates. The most important applications are September and November. Allow at least 6 weeks between applications. Soil test recommended.
Seasonal Care
March–April: Begin mowing at 3 inches, apply pre-emergent if needed, first fertilizer. May–June: Raise mowing height if temperatures rise, begin supplemental irrigation. July–August: Maintain consistent watering, avoid fertilization during peak heat. September–October: Best time to seed or overseed, aerate and fertilize — the most important maintenance window. November: Final winterizer fertilizer, continue mowing until growth stops.
RTF Fescue FAQ
What makes RTF different from regular tall fescue?
The rhizomes. Standard tall fescue is a bunch-type grass — it grows in clumps and can't spread to fill bare spots. RTF is the only tall fescue with true underground rhizomes that spread laterally through the soil, sending up new shoots to repair damage naturally. This means no clumping, no bare spots, and no annual overseeding.
Is RTF Fescue good for Tennessee?
RTF is ideal for Tennessee. It was specifically engineered for the transition zone — where summers are too hot for Kentucky bluegrass and winters too cold for bermudagrass. RTF handles both extremes, uses 30% less water than standard cool-season grasses, and tolerates the shade from mature trees that many Tennessee properties have.
Does RTF Fescue really repair bare spots on its own?
Yes. RTF produces true underground rhizomes — horizontal stems that grow through the soil beneath the surface and send up new grass plants several inches away from the parent plant. Bare spots from pet damage, foot traffic, or disease fill in naturally over the growing season. Barenbrug's testing shows RTF produces up to 20 times more rhizomes than other fescue varieties that claim spreading ability.
How does RTF compare to Kentucky bluegrass for self-repair?
Both RTF and Kentucky bluegrass spread via rhizomes, so both can self-repair. The difference is climate performance: Kentucky bluegrass struggles badly with summer heat in the transition zone and needs significantly more water. RTF gives you the self-repairing rhizomes of bluegrass combined with the heat tolerance, drought resistance, and shade tolerance of tall fescue.
