Needs light for germination so sow on top of the soil or only just barely covered

Rosa,

I did germinate them also in filter paper under light. Still, not a single seed sprouted. Anybody has any idea?

thanks

They do like to sprout in cool weather...myabe you need to place a sown and damp flat into the fridge for a couple of weeks and then take it out and place it in a sunny area...you should have sprouts in about a week to ten days.
