Good growing medium, right humidity, possibly a propagator and plenty TLC.
Keep them damp and warm. They need to be a certain temperature to germinate.
I keep old egg cartons (cardboard ones) and fill them with composted soil. Then I stick them in a bucket with about 1/2 inch of water in the bottom. After about a week, I put one seed in each egg holding compartment and barely cover the seed with dirt. The important thing next is to not water, but keep about 1/4 inch of water in the bottom of the bucket (to soak up into the soil). I also cover with a plastic bag (like you get from the grocery) then leave it alone for about 7-10 days. Seeds should sprout by then....
