The seed mix shown in Table 3.5 is a recommended low-growing,relatively non-invasive seed • mix appropriate for very wet areas that are not regulated wetlands. Other mixes may be appropriate, depending on the soil type and hydrology of the area. Recent research suggests that • bentgrass(agrostis sp.) should be emphasized in wet-area seed mixes. Apply this mixture at a • rate of 60 pounds per acre. • Table 3.5 Wet Area Seed Mix • % % °/a • Weight Purity Germination • Tall or meadow fescue 60-70 98 90 Festuca arundinacea or Festuca elatior • Seaside/Creeping bentgrass 10-15 98 85 • Agrostis palustris • Meadow foxtail 10-15 90 80 Alepocurus pratensis• Alsike clover 1-6 98 90 • Trifolium hybridum • Redtop bentgrass 1-6 92 85 Agrostis alba • Modified Briargreen,Inc.Hydroseeding Guide Wetlands Seed Mix • • 24. The meadow seed mix in Table 3.6 is recommended for areas that will be maintained infrequently • or not at all and where colonization by native plants is desirable. Likely applications include rural road and utility right-of-way. Seeding should take place in September or very early October • in order to obtain adequate establishment prior to the winter months. The appropriateness of • clover in the mix may need to be considered, as this can be a fairly invasive species. If the soil is amended, the addition of clover may not be necessary. • • • • • • • • Volume II—Construction Stormwater Pollution Prevention 3-13 • •
