Every year I sow 18 or so cells of Impatiens and every year I get 1 maybe 2 plants. Is there a secret to starting Impatiens I'm not aware of? I've researched online for directions, sowed the seeds on the surface , have them on a heat mat with a humidity dome and still nothing. Its only been 12 days but I'm starting to get anxious. Everything else is up and growing like crazy. Should I be worried?
Any suggestions?
