I need some help with this. I want to plant my 40 acres in trees. Right now I have 5 acres in trees and I'm using soaker hoses to water them. This isn't a viable method of watering for all 40. I think I need to do drip irrigation. How do I do this in such a large area?? Is this going to be cost prohibitive?? I'm nervous about it but I know I'm going to have to do it.
