I've got my tuna can out in the garden...

Sweet corn takes an inch of water a week. I started watering this past weekend.

A tuna can is about one inch deep. Fill the can, cut off the water...

Here I thought you were planting tuna cans hoping to grow more. The neat thing with corn is the leaves are designed to funnel water to the roots. I go out after a dew in the morning and most of the garden is dry but it is wet around the roots where the leaves have directed the water down the stalk.

Dang, y'all keep it up, I'm learning a lot about corn.
