Wildflowers are defined as being flowers that grow in a particular area naturally, with little or no care. There are many varieties of wildflowers, most of which are native to the United States. You can grow annuals, which will last longer through the season or perennials that won't last as long but will return the following year. Some gardeners plant wildflowers to attract butterflies and birds while others use them for cut flowers or to make dried flower arrangements. You can plant wildflowers in fields, beds or containers.
Choose wildflower plants that have the same light and moisture requirements. The plants should be native to your area to grow best. Make sure the plants have healthy white roots and have been kept watered.
Place the container in an area that will get full sun or full morning sun and partial afternoon shade for hot locations. Large containers will be harder to move once they are full of soil, so placing it first will save some strain on your back.
Mix 1 part compost to 3 parts soil from your yard and fill your container to within 2 inches of the top. Make holes in the soil with a small gardening spade as deep and wide as the containers the plants were purchased in.
Place each plant into a planting hole so that it is at the same level it was in the container. Hand tamp the soil around the plant and water thoroughly to settle the soil around the root systems of the plants.
Spread a layer of pine needles or shredded pine bark over the soil in the container. This will prevent weeds from growing and help to retain some of the moisture.
Water the wildflowers once a week while the root systems are becoming established. After that, water when the top 1 inch of the soil becomes dry.
Apply an 8-8-8 fertilizer once you start to see some new growth to the plants. Re-apply in summer if there has been a lot of rain or the container you are using is large. Follow the manufacturer's directions on amount to be applied.
