The annuals will reseed and the perennials will resprout. The second year should be more spectacular than the first. With a little luck, some patience, and the right weather and soil conditions, you will have a beautiful flower display for years to come. It is a great way to reduce the size of the lawn you currently maintain. Put out a little work in the fall when the weather is cool and mow once or twice a year.
Several factors contribute to problems with wildflower gardens.
One mistake is planting on an improper site. Remember, lots of sun and good drainage is a must. Wildflowers do not like wet or shady ground. Another problem you may encounter is too much competition from weeds. This can be a result of not properly removing the existing vegetation prior to preparing the site.
