My Grandfather was a firm believer in planting garden/crops on the right sign of the moon to get optimum growth and yield. For the past few years we've been planting tomatoes according to the farmers almanac which goes by by moon sign and we've had great success with tomatoes.
Coincidence? Maybe.
But...
The following photo has 2 tomato plants of the same variety, out the same batch, planted in tubs with the same type of soil...a controlled evironment. The one on the left was planted on a day NOT reccomended by the almanac, one on the right planted on a day MOST favorable for planting tomato plants.
I know this doesn't confirm anything but it does make you think.
We're gonna try another test with sign planting, this time with both plants in same tub, one planted on bad sign one planted on good sign.
