I am dragging the chain on seed planting this year.
It's just that every year, I feel that I jump out of the starting box just a bit early. This year I am going to wait until the spring equinox: 23 September.
I have only just found out about this... must have skipped that class in school.. oops.
I find it incredible that on this date, both hemispheres have equal day and equal night, and no matter where you are on earth (except the poles) the sun will rise due east and set due west.
