I get my calendar from the local feed store that has all the signs on it
Here's on the back page....
When the moon is in the barren signs, Gemini, Leo or Virgo, you can destroy noxious growth, deaden trees, pull weeds and turn sod best -- especially if the moon is in the last quarter.
Never plant anything in the barren signs, as they are only good for grubbing, trimming, deadening and destroying noxious growths...
yeah I know go ahead and laugh but once you plant, wean, castrate, etc according to the signs... you'll find they do better
gemini - arms
leo - heart
virgo - bowels
