SEED BED PREPARATION:
LIMING-Apply lime according to soil test recommendations. If the pH(acidity)of the soil is not known, an application of ground agricultural limestone at the rate of 1-1 4
tons/acre on coarse-textured soils and 2-3 tons/acre on fine-textured soils is usually sufficient. Apply limestone uniformly and incorporate into the top 4-6 inches of soil.
Soils with a pH of 6 or higher need not be limed.
FERTILIZER-Base application rates on soil tests. When these are not possible, apply a 10-10-10 grade fertilizer at 700-1,000 lb/acre. Both fertilizer and lime should be
incorporated into the top 4-6 inches of soil. If a hydraulic seeder is used, do not mix seed and fertilizer more than 30 minutes before application.
SURFACE ROUGHENING- If recent tillage operations have resulted in a loose surface additional roughening may not be required, except to break up large clods. If rainfall
causes the surface to become sealed or crusted, loosen it just prior to seeding by raking, harrowing, or other suitable methods for fine grading. The finished grade shall
be a smooth even soil surface with a loosen uniformly fine texture. All ridges and depressions shall be removed and filled to provide the approved surface drainage.
Planting is to be done immediately after finished grades are obtained and seedbed preparation is completed.

Maintenance: are both sun and shade tolerant.
Significant maintenance may be required to obtain desired Maintenance:
cover once centipede is planted. Acceptable for sodding. Hard Fescue is not recommended for slopes> 5%. Prefers shade.
SEED BED PREPARATION:
LIMING-Apply lime according to soil test recommendations. lithe pH(acidity)of the soil is not known,an application of ground agricultural limestone at the rate of 1 to 1 4 tons/acre on coarse-textured
soils and 2-3 tons/acre on fine-textured soils is usually sufficient.Apply limestone uniformly and incorporate into the top 4-6 inches of soil.Soils with a pH of 6 or higher need not be limed.
FERTILIZER-Base application rates on soil tests.When these are not possible,apply a 10-10-10 grade fertilizer at 700-1,000 lb/acre. Both fertilizer and lime should be incorporated into the top 4-6
inches of soil.If a hydraulic seeder is used,do not mix seed and fertilizer more than 30 minutes before application.
SURFACE ROUGHENING-If recent tillage operations have resulted in a loose surface additional roughening may not be required,except to break up large clods.if rainfall causes the surface to
become sealed or crusted,loosen it just prior to seeding by raking, harrowing,or other suitable methods for fine grading.The finished grade shall be a smooth even soil surface with a loosen
uniformly fine texture. All ridges and depressions shall be removed and filled to provide the approved surface drainage. Planting is to be done immediately after finished grades are obtained and
seedbed preparation is completed.
NOTES:
1. Permanent seeding, sodding or other means of stabilization are required when all construction work is completed according to the NPDES timeframe's table.
2. A North Carolina Department of Agriculture soils test(or equal)is highly recommended to be obtained for all areas to be seeded,sprigged,sodded or planted.
3. Use a seeding mix that will produce fast growing nurse crops and includes non-invasive species that will eventually provide a permanent groundcover.Soil blankets may be used in lieu of nurse
crops.Mat,tack or crimp mulch,as needed to stabilize seeded areas until root establishment.Mulch must be applied uniformly over the soil with a cover density of at least 80%.
4. Ground cover shall be maintained until permanent vegetation is established and stable against accelerated erosion.
