|SAE:||Establishment of a Community Roadside Wildflower Planting|
Get Wild with your SAE. Here is a great way to educate people about the environmental necessity, economic value, and natural beauty of native plants.
If you decide you want to plant a roadside area, you'll need to find out if the city, county, or state had jurisdiction over your site. Contact your state highway department's wildflower coordinator for information on the state wildflower planting program. What has worked? What hasn't? Asking these questions first can save you time and money.
Arrange a meeting with the area supervisor. Ask what the vegetation management program is. Will they defer mowing until after the seeds have matured? Do they spray herbicides that could kill your plants? Who is responsible for maintaining the site after planting? Find out what maintenance is planned before you plant. You don't want to waste your money planting seeds that will be killed after germination or that will be mowed before they're able to set seed. If you can provide seeds, many states will help with planting and management. Some states even offer cost-sharing or other funding programs. Select eight to ten indigenous species that will provide a blooming period of at least two months, and include annuals and perennials. Native species often prefer the poor soil that occurs along roadsides. However, it's best to choose a site that is relatively free of road salts, motor oil, competing vegetation, and construction activities.
You'll want to pick a highly visible site for the planting, such as a rest area, traffic interchange, park turnout, or the approach into town and you'll want to choose species that will be visible at 60 miles per hour. Bright splashes of color are more important than individual plants. Plant wildflowers at the recommended rates, concentrating on smaller, denser areas rather than on larger areas of sparsely planted flowers.
Remember that plantings covering one linear mile may be too ambitious! Existing vegetation at the site shouldn't be a tight turf. The ideal turf would be warm-season, clump, or bunch-forming grasses, but depending on where you live in Georgia you may have to plant cool-season grasses such as fescue or ryegrass on roadsides, which compete with overseeded wildflowers. Areas where cool-season grasses occur may have to be periodically replanted with wildflower seeds.
Watch out for newly constructed highways, whose shoulders are prime sites for wildflower planting projects. Seeds germinate more readily in loose soils than in hard, compacted ones. If you plan far enough ahead, the highway department could plant grasses that will be compatible with wildflowers when they plant along new roadsides.
Ask if your highway department, which probably owns a flail mower or other equipment that lightly scalps the ground, can prepare the ground for you. Leave the plots staked so you can monitor them over a three-year period. Knowing which species worked and which didn't will help you decide what to plant later.Be sure to use signs to call attention to your wildflower area. You want everyone to know your FFA made this beautiful area possible and to remind road crews that they need to treat the area with care.

Seeding Rate: In lieu of hydroseeding, simple seeding methods can be used to establish wildflowers. For large areas, use the seeding rate indicated for the individual wildflower mix or species, usually 10 pounds per acre. In smaller areas, seed at the rate of four to five ounces per 1,000 square feet or comparable species seeding rate. For small beauty spots, where intense color is desired, double the normal seeding rate. In small areas seeds can be mixed with damp sand and spread by hand. Seeding in large areas may be accomplished with a special drill seeder or by mixing seed with dry sand by spreading with either a drop spreader or rotary spreader. Maximum seed to soil contact must be made to give desirable germination of seedlings on sloping planting sites. Raking or pulverizing can accomplish this. When seeding wildflowers with soil stabilizing grass, reduce grass seeding rates by 25 percent and follow NRCS fertilizing recommendations. After wildflower establishment, competition by the nurse grass can be reduced by an overspray of Poast (Vantage), Fusilade, Ornamec, or Select.
Mowing and Maintenance: Wildflower establishment in normally mowed areas results in 25-30 percent savings in maintenance costs, with a payback in reduced maintenance after two to three years since average establishment costs for wildflowers is $500.00 per acre, discounting labor and profit inputs. Mowing is a valuable maintenance practice. Trimming the perimeter areas defines the wildflower area. In addition to the dormant mowing in late fall when seeds have matured, wildflowers may be mowed for reblooming in summer when drought/heat stress causes significant loss of color. Mowing high (four to six inches) and light fertilization will initiate reblooming of several species in three to four weeks. Desired annuals and perennials should be overseeded after fall clean up.
