I'm a newbie at planting seeds inside (and this is my first DG post). I was amazed at the growth of these bush beans in just a few days - reminded me of Jack and the Beanstalk! There are a few that are just coming up. Is it too early to start setting them outside to harden? The temp has been hanging around 50-57 the last few days here in Fort Mohave, AZ. I just constructed my first square foot garden bed and have a spot to plant them - need to put up a trellis yet.
