Impatiens seeds are usually started several months ahead of the average last frost date. They do not need pretreatment but they do need a warm soil temperature to germinate. Once they have true leaves, they should be fertilized lightly and grown in bright light. As the plants grow, they should be moved into larger pots to avoid crowding. Finally, they would need to be hardened off or gradually acclimated to the outdoors and then planted outdoors when the soil has warmed and all danger of frost has passed. I hope this answers your question.
