What kind of peas do you plant that you can start them indoors?
Snow peas..... :)
No kidding.
Seriously, I start them in peat pots and then dig a trench and place them in the trench.
They start much better indoors where the soil is warmer. Once they’re up and the weather isn’t horribly freezing, I put them out. They can take a light freeze, down to about 28 and bounce back.
