I was just talking about this on Facebook @ Hollyberry Herb Farm. This is a great chart, Thank you Town and Country Gardening.
Temperature, it’s all about the soil temperature.
Soil temperature is almost never to warm, however, soils that are to cool and damp at worst can cause your seed to rot in the ground and at best take many days to germinate. Seedling in cool soil grow slowly and often do not develop into healthy productive plants.
