Sidalcea "Elsie Heugh" seeds not germinating
I sowed these just over two weeks ago. I read that they needed a period of chilling so I put them in the fridge for two weeks. Pressed down onto the soil. Lightly covered with perlite. Kept under my lamp, in our garden room. All my other seeds have germinated, but not these. Not one single one. What have I done wrong? Does anyone know how long they usually take to germinate?
