WETLAND DEVELOPMENT
VEGETATION PLANTING FOR MARSH DEVELOPMENT


Planting Methods

A firm seedbed is essential for vegetation establishment. A well-packed seedbed will permit a close seed contact with the soil and a shallow, precise seeding depth.

Seeds can be planted with a no-till grass drill equipped with a seed box agitator, which is the recommended method. Drills without grass seed attachments may have difficulty seeding light or chaffy grass seeds.

Unless planting in cropped fields where competition is expected to be minimal, the existing vegetation will need to be killed with herbicide and organic matter will also need to be removed. Grasslands should be mowed and burned prior to herbicide application.

Plants can be planted by using conventional tillage methods if no-till equipment is not an option. The area to be planted (if the soil has been disturbed by construction) should be disced and then rolled with a cultipacker. This very firm seedbed is necessary to keep the seed from settling down too deep in the soil and allow the seed to be placed in close contact with soil. Seeds can then be planted using a fluffy seed grass drill, *hydro seeder (the amount of fibrous material should be reduced so not to impair the growth of the Cover/Companion Crop or marsh vegetation and the amount of native should be doubled), air seeder (with lime or potash as a carrier), fertilizer cart or other seed spreaders with a seed carrier. In these methods, the area should be cultipacked after planting.

*hydro seeding is a controversial method of planting marsh seeds and should be investigated completely by the contractor before using this method to establish native vegetation.


PLANTING TIMES

Seeds should only be planted May -- July or after the first frost in the fall. If a cover/companion crop needs to be planted to prevent soil erosion than the seeds can be planted with a no-till grass drill through the cover/companion crop.

NATIVE GRASS PLANTING TECHNIQUE

Planting Methods

A firm seedbed is essential for prairie vegetation establishment. A well-packed seedbed will permit a close seed contact with the soil and a shallow, precise seeding depth.

Seeds can be planted with a no-till grass drill equipped with a native grass box and seed agitator, which is the recommended method. Drills without grass seed attachments may have difficulty seeding light or chaffy grass seeds.

Unless planting in cropped fields where competition is expected to be minimal, the existing vegetation will need to be killed with herbicide and organic matter will also need to be removed. Grasslands should be mowed and burned prior to herbicide application.

Native grasses can be planted by using conventional tillage methods if no-till equipment is not an option. The area to be planted (if the soil has been disturbed by construction) should be disced and then rolled with a cultipacker. This very firm seedbed is necessary to keep the seed from settling down too deep in the soil and allow the seed to be placed in close contact with soil. Prairie seeds can then be planted using a fluffy seed grass drill, *hydro seeder (the amount of fibrous material should be reduced so not to impair the growth of the Cover/Companion Crop or native vegetation and the amount of native seeds should be doubled), air seeder (with lime or potash as a carrier), fertilizer cart or other seed spreaders with a seed carrier. In these methods, the area should be cultipacked after planting.

*hydro seeding is a controversial method of planting native seeds and should be investigated completely by the contractor before using this method to establish native vegetation.


**Plateau herbicide is a pre or post emerge applications on native planting sites. Plateau can be applied at rates of 4 to 12 ounces per acre for residual weed control. Plateau can be applied with other pre-emerge herbicides up to 14 days after planting when targeted annual weeds have emerged but are less than 6 inches tall. Plateau will provide residual weed control for up to 2 months after application. Plateau is not recommended for establishment of Switchgrass. Plateau can also be safely used at the beginning of the second growing season should weeds become a problem.

PLANTING TIMES

Native seeds can only be planted May and June or after the first frost in the fall. If a cover/companion crop needs to be planted to prevent soil erosion than the native seeds can be planted with a no-till grass drill through the cover/companion crop.

Cover/Companion Crop

Spring: Annual Rye (Lolium multiflorum) at 20 lbs. Per acre
Fall: Oats (Avena sativa) at 32 lbs. Per acre.

Cover/Companion Crop should be planted at the amounts indicated above because higher amounts will impair the growth of the native vegetation.
