Seeding mixture
Species' Rate (Ib/acre)
Tall fescue BO
Pensacola Bahiagrass 50
Sericea lespedeza 30
Kobelespedeza 10
Seeding notes
1. From Sept. 1 - Mar. 1, use unscarified sericea seed.
2. On poorly drained sites omit sericea and increase Kobe to 30lb/acre.
3. Where a neat appearance is desired, omit settees and increase Kobe
to 40 lb/acre.
Nurse plants
Between Apr. 15 and Aug. 15, add 10lb/acre German millet or 15lb/acre
Sudangrass. Prior to May 1 or after Aug. 15. add 25 Iblacre rye (grain).
Seeding dates
Best Possible
Early spring: Feb. 15 - Mar. 20 Feb. 15 - Apr. 30
Fall: Sept. 1 - Sept. 30 Sept, 1 - Oct. 31
Soil amendments
Apply lime and fertilizer according to soil lasts, or apply 3,000.5,000lb/acre
ground agricultural limestone (usethe lower rate on sandy soils) and 1,000
lb/acre 10.10-10 fertilizer.
Mulch
Apply 4,000 lb/acre grain straw or equivalent cover of another suitable
mulch. Anchor straw by tacking with asphalt, netting, or roving or by crimp-
ing with a mulch anchoring tool. A disk with blades set nearly straight can
be used as a mulch anchoring tool.
Maintenance
If growth is less than fully adequate, refertilize in the second year, accord-
ing to soil tests or topdress with 500 lb/acre 10-10- 10 fertilizer. Mow as
needed when sericea is omitted from the mixture. Reseed, fertilize, and
mulch damaged areas immediately.
