Eliminating Bermuda Invasion in Tall Fescue Lawns

The Bermuda Problem

Bermuda grass invading Rebel Supreme Tall Fescue. Once established, Bermuda is nearly impossible to selectively remove.

Eradication Options

Nuclear Options (Kill Everything)

• Non-selective herbicide (RoundUp) – NOT recommended for intelligent gardeners
• May require 2-3 applications
• RoundUp dangers: well-documented environmental/health concerns

Solarization (Earth-Friendly)

• Water thoroughly
• Cover with CLEAR plastic in summer heat
• Weeks later: everything dead
• Remove plastic, start over with sod/seed

Black Plastic Alternative

• Blocks light → grass dies from darkness
• Slower than clear plastic solarization
• Effective for smaller areas

Why Selective Removal Fails

Bermuda's aggressive stolons/rhizomes intertwine with fescue. No herbicide kills Bermuda without killing fescue. Physical removal leaves fragments that regenerate.

Prevention Going Forward

• Healthy, dense fescue at correct mowing height resists invasion
• Organic program builds soil favoring desired grass
• Immediate action on small patches before establishment
