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!
Farming is for wealthy people. They can afford to do it longer before they go broke.
