I also save seed but have not had your problem. I put the seed in packets/evelopes in a large galss jar with about 1/2 cup of dry milk llosely wrapped in facial tissue (like Kleenex). This seems to provide the dessicant necessary. Then I keep the jar in a dark and cool place for the winter. JonquilJan If you know others, you are learned. If you know yourself, you are wise.
