That's a great quick idea to have proper spacing with minimal effort.
But I have a burning question. And I don't want to seem rude or anything but... Why did you leave the 'high vis orange plastic barrier material' on once they were cut and planted?
Wouldn't the slit (X) tell you where they should be located (if they failed to sprout)? Does it not interfere a little when removing the dead stalk at the end of the season?
Sorry, I'm just trying to learn and thanks to youtube and their world full of regurgitaters, I am forced to ask the unasked.
