Watering raspberries

I water the raspberries by hand. I use 2.6 and 3.1 gallon watering cans. Under each bush I pour 0.7 gallons of water. I have 150 raspberry bushes. I need 105 gallons of water to water everything. Water has to be carried through half the garden. It's about 180 feet. It takes about 4 hours to water everything. But this is if the water goes well. I can of course use a hose. But then the magic of the garden is broken. After all, the garden is not for fruit. The garden is what makes the right mood :)
