The seeds will probably be fine. Not clear on what zone you're in, but what
the heck. Plant them and go for it.
I remember reading an article about some USDA office that had seeds in a
drawer of a desk that had been there since the '40's. No refrigeration, no
nothing. The seeds were over 80% viable. Go for it!

Hi,

I was cleaning out some drawers and I found a packet of tomato seeds
from 1991. Are they still viable?

If they are, is August a good time to start tomatoes in La Mesa, Ca?

Thank you for your time,

Karen R.
