... Also you mention seed libraries ? Do you mean like browse through a catalog and order ahead of the season? I have an online acct with Boston Public Library; do you mean check out those resources?
some libraries will have a garden seed collection that people work with and maintain. free for people to use. if you are into gardening you can talk to your local library and ask them if they would let you start one. the idea is similar to a book reading library, but instead of checking out books you get some seeds of whatever you would like to try to grow and in return you can bring seeds back after they grow or you can bring in things they don't have to share or ...
you can use lime in gardens if the pH is too low to bring the pH up, but you may not really need it. corn not growing can be for more than a single reason so i would not jump to that conclusion from a single attempt.
