This year I have harvested more seeds than I will use next spring. I plan to vacuum-seal them and I want to know if, except for drying them really well, I should consider anything in particular.
These seeds were harvested from plants that belong to the following genera: Calendula, Celosia, Centaurea, Cosmos, Dianthus, Echinacea, Helianthus, Lavatera, Matricaria, Tropaeolum and Zinnia.
The enemies of seeds are: heat, light and humidity, by controlling these you can store some seeds for many years.
Keep seeds at a cool to cold temperature of 40 degrees or less.
Avoid fluctuations in temperature such as a garage or storeroom that is cold in winter but blazing hot in summer.
Avoid light and never store seeds in direct sunlight or a well lit room.
