Sometimes gardeners - I know I do - get tired of being berated for gardening sins of omission or commission. One of the most forgiving, intelligent, and wickedly funny gardening writers I know of is Henry Mitchell who was, for a quarter of a century, the gardening columnist for The Washington Post. He'll make you feel less ashamed of your own gardening errors as he cheerfully includes himself among the gardening sinners. There are three books of his collected columns and a couple of other books besides - not necessarily about gardening. I read them and then bought them and each winter when it seems, in Canada, as if spring will never come, I treat myself to some Henry to keep my spirits up and my gardening brain honed to be ready to leap into action on the first decent gardening day. Try him - you'll love him!
