I have tried various methods to sprout my seeds. I have them in regular potting soil, takes anywhere from 5 to 20 days to sprout.
I have been using another method that gives me 90 % success rate.
I nick the seeds, place the in a damp paper towel surrounded by ground up sphagnum moss and place in a plastic baggie and them place them on top of an under counter refrigerator. the temp on top of the fridge is a steady 90 degrees.
they sprout anywhere from 3 days to a week. I then carefully place them into individual peat pots with more ground up moss on top.
after placing the sprouts in the pots, they come to the surface in a few days.
see photo. these sprouts are from a cross between moonstruck and wild grape.
