Good growing medium, right humidity, possibly a propagator and plenty TLC.
Make sure you have the right soil, keep it damp and enough sunlight. And don't move it around.
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....
