Planting is an inexact science, but here you go

Some time back I wrote that at a future date I’d print seed-starting dates for the remainder of the growing year. I’ve had a couple people ask about that, so I thought now would be as good a time as any to fulfill that promise.

I put together this calendar while farming for a living. Gardening is an inexact science, but I found that as a general rule these dates worked out more often than not. Having a list or calendar at least provides a reminder and guide to get things in that otherwise might be forgotten.

One important note: if you live at elevations higher than 3,000 to 4,000 feet then you might want to add two or so weeks to these suggested planting dates.
