Hi PhoenixV: You don't really need books. Just go online if you have a question and type your question into the browser and the internet has so many answers for anything about gardening. Also if you have a question I might have the answer. I would check the library for gardening books if you are looking for gardening books. Also, there might be some good e-books online. Lulu.com sells ebooks and several other places.
I hope this helps and if you have another question then let me know.
