Is there a web site which gives instructions for saving seed from vegetables and fruits? I know the general method but there are some seeds which require special handling. For example, last Fall I saved seed from feijoa (pineapple guava) and those seed had to be allowed to sit in a bit of water, to ferment a few days, before drying. I successfully sprouted them. I would like to find a site which had this sort of special information about a wide range of fruits and vegetables.
