Look in second hand stores for some gardening books.
I got this [one] (http://www.amazon.co.uk/The-Gardening-Year-Readers-Digest/dp/0276001354) for €2 recently and its particularly well illustrated and informative. I have a fair collection now it's turned into a bit of a hobby in itself to collect them!
