So sweet pea (flowers) are not frost hardy like eating peas and have a higher germination temperature? If you're direct sowing them, you'd plant them after all danger of frost has passed? Or they are somewhat frost tolerant and I can direct sow them a couple weeks before my "Definitely Won't Get Frost" date?
One source is telling me that the germination temp is 65-75 degrees, another, 55-65. Regardless, if I sprout them, do I need to make sure the soil that I put the sprouts in is around the same temp as I sprouted them? Does that question make sense? If I sprout them in the house at around 70 degrees and put them in soil that is, say, around 50 degrees, will they die?
Here's another dumb question: If I decide that I need to find out what the actual soil temp is, do I have to buy a soil thermometer? Or can I just stick my meat thermometer into the ground as far as it will go? (Shhh! Don't tell my dinner guests!)
