Q.Growing Blackberries

I am a bit confused as to how do you measure water using inches? Water as far as I remember is measured using volume units, not length units. This refers to your article on growing Blackberries where you recommend to water the bushes 1 inch of water per week.
Thanks abbabba

Typically, water would be measured by a rain gauge, which gathers a square inch of space to gauge how much water has fallen. So, for example, 2 inches of water would be roughly about 2 ounces. So for a square foot, about 2.25 gallons per week - for an inch it would be half this amount.

It is a good idea to water deeply (for about 20 min. or so) every other day or two, depending on the weather. Once temps reach 85 F and up, daily watering is often necessary.
