The wife found this image on social media from homesteadspirit.com and sent it to me the other day. I give her credit... she does know her husband.

She can see from my behavior, and the dearth of catalogs and posts, that I'm starting to get the itch to go outside and play in the dirt. Now, I have no idea what Cold Hardiness Zone these dates pertain to, but for me in Zone 6a, the dates are actually pretty close.

You'll notice that there doesn't seem to be any logic, rhyme, or reason behind how this data was assembled... at least I couldn't discern one at any rate. So I re-typed it into Excel and then sorted the data based on Seed Starting Date. You're welcome.
