Well, I wouldn’t say I’m an expert on anything. But, saying that, I follow a simple rule, plant above ground crops during the waxing (1st and 2nd quarter) moon, and root crops during the waning (3rd and 4th quarter) moon phases. I also try to plant according to the best sign during that moon phase, generally, above ground crops, like tomatoes, peppers during a ‘water’ sign (Pisces, Cancer, Scorpio); and for a root crop like potatoes, an ‘earth’ sign (Taurus, Capricorn, Virgo).
Here’s some details about what I said.
We planted our taters accordingly, and they took off after planting. But due to dry weather and weeds, our crop may not end up being that good.
