Your email prompted me to do some poking around on the web. I could not find any scientifically robust evidence that moon planting does, or doesn't, make a difference. I think one really clear principle that argues against any influence is that the most powerful known force at work between the moon and any object on earth is gravity. The gravitational attraction between the moon and a single seed is so negligible as to be unmeasurable (I think it's much smaller than the attraction between you and the seed, but I don't have the calcs at hand to confirm that), and is dwarfed by other effects having nothing to do with the phase of the moon, such as air pressure, humidity, soil moisture and chemistry, electrostatic charge, seed orientation, etc. etc. etc. 

A believer is likely to counter that the key word in the above paragraph is "known." If one believes in forces unknown to physics, then it's a different conversation. But to my mind, extraordinary claims require extraordinary evidence--i.e., rigorously conducted, blinded tests giving results that can be reproduced by others--and I don't think that exists for moon phase planting.
