I thought I'd try and save money on bedding plants this year by growing more from seed but it's three weeks since I sowed my trailing lobelia seeds and there hasn't been the slightest sign of germination. Am I being to impatient? I have them on a dining room windowsill which has good light and daytime temperatures of around 21 degrees. Any comments or hints would be really helpful as I have some of the seeds left in the packet and could do something different next time!
