...is your garden journal. Do you have one?
I think last year starting a garden journal was the best piece of advice someone gave me. How else would I remember how long it took for my seeds to germinate or get their first true set of leaves or when my first cherry tomato ripened. This information is very helpful when the Impatience sets in. You know what I'm talking about...when it just seems like that seed isn't going to sprout or those tomatoes are never going to turn red.
Your journal doesn't need to be fancy; a simple notepad would do. And, your journal doesn't need to have an entry every single day. You can just write on the more significant days (planting, sprouting, putting outside, harvest, etc).
Putting together a journal can be a fun way to spend an hour or so in anticipation of planting.
