I use a sterile seed-starting mix. Usually they're made out of
ground-up peat moss, vermiculite and sometimes fertilizer. It's a
light medium which seeds like. More important: It's sterile, which
means no soil-borne diseases like damping off. You can get it at
Lowes or any garden center. I usually special order big bags, since
it's cheaper than the sizes normally carried.

It's also important to use clean pots. I use 5 oz. disposable plastic
drinking cups, with 4 holes poked in the bottom with an ice pick. If
you make holes in 2 at a time, they hold up better. They're a good
size for a plant, with no need for transplanting seedlings. They hold
up well til you get the plant in the ground. And you can write on
them with a glass-marking pencil. And they fit nicely in trays.

Best wishes, Dianna
