• Dig a hole 2 to 3 feet deep and 6” to 12” wide. • Scuff the sides if they were glazed by the digging tool. • Fill the hole with water, then let it drain. • Fill the hole a second time and measure how much water drains per hour for several hours. • A rate of about 2 ” per hour is ideal, and 1-3” generally is okay. • Less than 1” per hour or significantly more than 3” per hour is problematic for perennial crops.
