SEEDING MIXTURE RATE (lb/acre)
Tall Fescue 80
Sericea Lespedeza 20
Kobe Lespedeza 10
SEEDING NOTES
After Aug. 15 use unscarified sericea seed.
Where periodic mowing is planned or a neat appearance is desired,
omit sericea and increase Kobe lespedezo to 40 Iblacre.
To extend spring seeding dates into June, add 15 Iblacre hulled
Bermudagrass. However, after mid —Apr. it is preferable to seed
temporary cover.
NURSE PLANTS
Between May 1 and Aug. 15, add 10 lb/acre German millet or
15 Iblacre Sudongross. Prior to May I or after Aug. 15 add
40 Iblocre rye (grain).
SEEDING DATES Best Possible
Falk Aug. 25 Sept. 15 Aug. 20 — Oct. 25
Late Win ter. Feb. 15 Mar. 21 Feb. 1 — Apr. 15
Fall is best for tall fescue and late winter for lespedezos.
Overseeding of Kobe lespedeza over fall —seeded tall fescue is
very effective.
SOIL AMENDMENTS
Apply lime and fertilizer according to soil tests, or apply
4,000 Iblocre around agricultural limestone and 1,000 Iblacre
10-10-10 fert&lzer.
MULCH
Apply 4,000 Iblocre grain straw or equivalent cover of another
suitable mulch. Anchor straw by tacking with asphalt, netting,
or roving or by crimping with a mulch anchoring tool. A disc
with blades set nearly straight con by used as a mulch
anchoring tool.
MAINTENANCE
Refertilize in the second year unless growth is fully adequate.
May be mowed once or twice a year, but mowing is not necessary.
Reseed, fertilize, and mulch damaged areas immediately.

Planning and Design Manual, 1988.
SEEDING MIXTURE RATE (I/acre}
Species 200 (4_511, 000ft 2)
Tall Fescue
NURSE PLANTS
Between May 1 and Aug. 15, add 10 Iblacre Sudangrass or
10 Iblacre German millet. Prior to May 1 or after Aug. 15 add
40 lblGcre rye (grain).
SEEDING DATES
Best: August 25 — October
Possible: February — April 15
Avoid seeding from Nov. to Jan. If seeding must be done at this
time, add 401blacre rye grain and use a channel lining that offers
maximum protection.
SOIL AMENDMENTS
Apply lime and fertilizer according to soil tests, or apply
4,000 Iblacre ground agricultural limestone and 1,000 lb/acre
10-10-10 fertilizer. Operate tillage equipment across the waterway,
MULCH
Use jute, excelsior matting, or other effective channel lining
material to cover the bottom of channels and ditches, and staple
securely. The lining should extend above the highest calculated depth
of flow. On channel side slopes above this height, and in drainages
not requiring temporary linings, apply 4,000 lb/'acre grain straw
and anchor straw by stapling netting over the top.
Mulch and anchoring materials must not be allowed to wash
down slopes where they con clog drainage devices.
MAINTENANCE
Inspect and repair mulch frequently. Refertilize in late winter of
the following year, use soil tests or apply 150 Iblocre 10-10-10.
Mow reqularly to a height of 2-4 inches.
Refer to Appendix 8.02 for botanical names.

Maintenance Inspect sediment fences at least once a week and after each rainfall. Make any
required repair-, immediately.
Should the fabric of ®a sediment fence collapse, tear, decompose or become
ineffective, replace it promptly.
Remove sediment deposits as necessary to provide adequate storage volume
for the next in and to reduce pressure on the fence. Take care to avoid
