Although we are now past our LAST FROST DATE here in Redding, it's still a bit early to plant out my eggplants and peppers. these nightshades are particularly picky and like the soil temperature to be at 65 degrees F, which means the nighttime temperatures are staying above 50 degrees F. So I have planted out almost all of my tomatoes this week and the potatoes went out in mid-March, although they could have gone in a bit earlier. I also have tomatilloes and ground cherries, also nightshades, to plant, but I have no idea where they are going to go...
Here's a nifty little site that is full of great information in addition to a soil temperature map. Greencast is mainly a turf management site, but this is a great place to find your soils temperature at all times of the year, as well as evaporation information.
