The RHS proclaim it to be the best way Chris! But I've never stored
mine in the fridge or freezer. Tiny one would burn, I always thought
and then if I want to scater them the following year, I defrost and
refrost?! I think it's not a good idea. Also I had a bad time once
freezing some capper seeds - they got too damp and moldy. I lost the
lot. I keep my seeds in paper envelopes, most of them I make myself or
use old seeds packets making sure I put the name on it. All are kept in
tins, one for flowers, the other vegs. I've done this for as long as I
can remember. This year I have grown 2 years old tomatoes seeds - all
came out and I managed to successfully grow proteas from seeds last
year, given to me by a friend who kept them in her shorts pocket for 3
weeks whilst visiting south africa )
