Very informative but light-hearted and funny. Includes areas to write in dates relevant to your planting zone and make some notes. I also really liked the fact that all of the pest management and fertilizer tips were for a more organic rather than chemical-based approach to gardening.
I have not actually followed their plan yet so I don't know how well it works in terms of getting plants in the ground and getting good harvests, and it's a bit late this year, but I'm looking forward to using their plan next year--particularly with regard to the stuff that needs to be done before the average last frost date. I usually forget until the weather starts to be nice and by then I've missed my chance to get a really good start on the growing season.
