I buy any gardening book that has to do with PA. I also buy the farmers Almanac every year and know whether it's a good year to plant things or not. It nailed it this year ... rain, rain, rain. So I didn't plant a garden or any flowers at all. Didn't even buy a hanging basket. I also have books on bulbs, perrenials, annuals, tree's, shrubs, and houseplants including bonsai tree's. You can never have too many books!!! At least thats what I tell the hubby
