Farmers have planted and harvested crops "by the moon" for centuries. Though there isn't a lot of scientific evidence to support it, many still believe and some reports do support it.
I think the general "Rule of thumb" is plnt root crops, carrots, 'taters, radish, on a "waneing" moon(on the decrease, from a full moon) and flowering crops in the "waxing" moon(not sure of that term, but while the moon is increasing from a new moon toward full).
I have also read that clones taken and rooted during the "Waxing" moon(if thats the correct term) have greater survival rate and root faster.
