Moon sign planting always seemed so complicated...
Then I found: http://www.Almanac.com/PlantingTable
Makes it very easy to follow.
As to the validity or scientific reasoning, I guess you could equate it to the tides - which even affects ground water too. Such as weeding at what would be the lowest tide period would cause weeds to dry more and die sooner. Water preferences vary for root and above ground plants, and therefore selecting the cycle where the most favorable conditions exist for that plant gives them the best chances of germinating and starting better. (At least that is my take on it.) I have heard lots of other things about benefits too. All I can say is those who use it swear by it and those who don’t wonder if it works.
There are lots of examples of other effects too, like sawing lumber for air drying (heated drying overcomes it). Sawing at the wrong time results in warping and skewing - at the right time yields straight boards. (My father learned that in the late 40’s - long story.)
Bookmarked the page.
