Recommendations for all new DOT contractsInvolving native plant installations on roadways
1. Include 6-9 months dedicated to weed eradication
2. Induce multiple weed flushes with irrigation, deep soil wetting essential
3. Kill weeds with mixture of systemic herbicides for both grass, broadleaf and sedge plants
4. Anticipate 3-5 spray applications 5. Why?

Recommendations for all DOT contractsFor large scale establishment on roadways
1. Protocol for Pili grass starts after weed eradication period, 3 phase approach
2. Phase 1: drop seed on drip line and cover w/hydro-mulch cap
3. Phase 2: fertilize and mow – develop enhanced plant structure for seed production
4. Phase 3: seed laden mulch used to populate between row space

Cutting Pili grass too short results in some
stem death and loss in vigor

Recommendations for all DOT contractsFor large scale establishment on roadways
1. Protocol for Pili grass starts after weed eradication period
2. Permanent drip irrigation lines for establishment and long term persistence
3. Assuming a shortage of seed for broadcast establishment, 3 phase approach
4. Drop seed & cap, mowing to develop seeding plant structure, seed laden mulch for b/w spaces
