Yes, I have seriously overthought this. Also, I have a lot of stuff to plant. Good grief. But I love having a plan, love knowing that I get to start in a week and a half, love knowing that while there’s not a lot to do now, I’m going to be busy for the next six months after.

*As soon as soil can be worked
