Answer: To be quite honest, in my experience zinnias are no more difficult than other plants. They do grow rather quickly so it is a good idea not to start them too early -- four to six weeks is plenty of time and be sure to wait to set them out until all danger of frost is past and the soil has warmed a bit. (An exception to this might be the Zinnia augustifolia types which need warmer temperatures and a longer lead time from seed but are fabulous garden plants.) Good luck with your zinnias!
