Squaring my Circle

 I am reading this book about gardening and thinking how easy it is when you are in the States and you know your last frost date and zone and so on... Amazingly, all that info was just a websearch away! So: Last Frost: Zone 11, Apr. 21 - Apr. 30 First Frost: Zone 12, Nov. 21 - Nov. 30 Plant Hardiness Zone 7b -15°C to -12.2°C   Now I'm off to do some serious planning! Thanks PlantMaps !
