Starting seeds

I've decided to start some seeds.  I planted the following:

Tomatoes
Chilis
Peppers

Pawpaw Seed Stench

I decided to peel back the seed coat on my pawpaw seeds in hopes of discerning if the seeds are viable and enhancing germination.  Well some of the seeds were dried out and others appeared in good shape.  However the viable seeds reek of unwashed, crusted, week old butt.  They smell horrible!

Pawpaw Sprout

I tried germinating pawpaw seedlings back in November.   Out of seven seeds I only had one successful germination.  The picture shows the sprout breaking through the soil.
