Wildflowers can give a drab section of landscape a beautiful pick-me-up. All you need is a sunny area and some time to grow wildflowers. The most difficult part is the site preparation; growing the flowers is quite easy. Flowers of every color will grace your landscape with very little care. When using native wildflowers, you will grow hardy flowers that attract butterflies, bees and hummingbirds. Wildflowers are good for the environment and provide a natural, beautiful garden.
Prepare your site by adding compost over the soil and tilling to a depth of about 4 inches. The tiller will mix the compost into the soil. Rake out weeds and old grass. If you are sowing a large area, wait at least two weeks, then till and rake again. Rake the area out to create a level flower bed.
Buy seed native to your geographical area and plant in early spring. Sow about a third annual seeds to two-thirds perennial. You can find the coverage per square foot on the back of the seed packets.
Prepare seeds for planting, if needed to germinate. This information will be on the back of the seed packets. Preparation might include placing the seeds between two pieces of sandpaper and rubbing them together, or placing the seeds in moist paper then in a plastic bag and putting them in the refrigerator for a couple of weeks. Most wildflowers, however, do not need such treatment.
Place half the seed in a bucket and mix one part seed to 10 parts sand. Use a hand-crank cyclone seeder or spread the seed mixture by hand. Sow the entire area with the first bucket of seed-sand mixture. Mix the rest of the seed with sand and spread it.
Use a lawn roller to press the seed down on the surface of the soil. Wildflower seed will not germinate unless it has good contact with the soil.
Spread a light covering of straw over the seed bed. The straw will keep moisture in the soil, keep the seed from floating when watered and help keep birds from eating the seed.
Water to keep the seed bed moist every other day until the flowers come up. After they sprout, water only when the weather is very hot and dry.
Mow the flower bed in late fall or early winter when the flowers start to die off. Mowing on a high setting will help distribute new seed for the following spring and keep weeds and other plants from establishing in your flower bed.
Replant annuals in the early spring. They will come faster than the perennials and give you a longer flowering season. Add new perennials if you want to make the garden thicker.
