ref: you want the water and food at the bottom not the top

Indeed, the roots need the water.

I plant my potatoes down to a spades depth so when the hilling up is done, I figured that hoeing a trench in along the center of the hilled row and filling it with water would concentrate the water down to the roots.

If you just spray water on the hills, it runs down the side and less gets to the roots.



I appreciate it late for planting but I'll see how growing goes in the warmer months.
