There are lots of ways to start seeds and everyone has their favorite method.
This year I think I'll be sticking seeds collected from my own plants directly in ground.
(Getting tired of any extra work transplanting seedlings)
Otherwise, my favorite way of starting seeds is to use Perlite moistened with distilled water
and peroxide in a baggy. I think I'm using about 20 oz. distilled water and a teaspoon of peroxide.
There are lots of formulas online.
Moisten the Perlite and drain off any excess. Add the seeds and set in a warm spot out of direct sun.
If you need to stratify, put the baggy in the fridge for 3 weeks prior to putting in a warm spot.
Then check occasionally for any green showing.
When there is green, I then plant in ground and cover with Perlite to discourage fungus gnats.
Like said, everyone has there own method. I've tried methods of some and had 0 luck.
You'll need to experiment.
