Sowing by the phase of the moon

Moon gardening may work, but I am not methodical enough either to do it, or to keep notes to record if it actually works.

I am happy to potter in the garden any time, but I've noticed I get a real urge to be out there planting/sowing/moving stuff just before it rains. My mum was the same, so much so that even the neighbours expected rain when she was furtling about, whether the sky was overcast or cloudless.

I wonder if subconsciously we both react to a change in the pressure as the glass drops towards rain?
