Sow wildflower seeds to create a striking natural and changing display of colorful flowers. The display will change as new flowers come into bloom and some more aggressive flowers edge out others. Preparing the planting site in which to sow wildflowers entails some time and effort, and maintaining the planting site requires basic gardening skills. Wildflowers are very versatile and can provide a less formal, more interesting array of flowers or a splash of color to borders or areas around trees. Choose wildflowers that are native to the area and fully acclimated or sow wildflower seeds that are new and interesting.
Select a planting site with full sunlight at least six hours per day and up to 12 hours if possible. The planting site should have good drainage and aeration and be protected from prevailing winds by a building, wall, shrubs or fence lines.
Eliminate weeds by watering them to stimulate growth and then pulling them by hand or spraying them with a weed-specific herbicide, following label directions. Herbicides are available at garden stores. Grass provides protection against erosion and some seed mixes contain grass seed.
Incorporate compost or sphagnum peat moss into the top 6 inches of soil with a shovel or rototiller. Use 3 cubic yards of organic matter per 1,000 square feet.
Water the planting site to germinate any weed seeds that are brought to the surface and apply herbicide, according to label directions, as soon as they bloom. Repeat the process until a manageable number of weeds continues to bloom.
Choose a wildflower seed mix that creates the effect you want and one that flourishes in your site according to the label. Select a formulation that states on the label the different heights, colors and bloom times so a continuous and changing array of flowers can be grown.
Sow seeds in the fall and water them in the spring to germinate the seeds, or sow the seeds in spring or early summer.
Sow 4 to 8 oz. of seed for each 1,000 square feet or follow directions on the package for specific seeds. Rake the planting site lightly, mix six parts dry sand to one part seed, and sow small planting sites by hand. Lightly tamp the seed into the ground with your feet after planting. Use a fertilizer/seed spreader, available from home improvement centers, for larger sites.
Continue to pull or spray with herbicide any weeds that come up after the wildflowers are established. Water the wildflowers once per week until the soil is damp to a depth of 6 inches.
