I tried to plant by the moon a couple of times years ago but didn’t see a difference. Maybe that’s why last year was the worst ever.

Jan. 23rd-27th A barren time. Best for killing weeds, briars, poison ivy, and other plant pests. Clear wood lots and fencerows.
28th-29th A favorable time for sowing grains, hay, and forage crops. Plant flowers. Favorable days for planting root crops.
30th-31st Start seedbeds. Good days for transplanting. Plant carrots, turnips, onions, beets, Irish potatoes, other root crops in the South. Also good for Leafy vegetables.
The amount of rain you get is important but the *timing* of it is just as important.
If corn gets plenty of rain *except* when it tassels, you still won’t have a great corn crop.
Each crop has its preference for when it most wants water so I make sure I water the garden throughout the season as I rarely plant full rows of anything these days.
When growing on a large scale if you don’t irrigate there is the occasional year when you can do everything else perfectly and still have a disappointing crop.
And there is the occasional year when you can do everything wrong and still have a surprisingly good crop.
My great uncle used to say that farming was Gods way of keeping man humble.
I believe it!
