This is a really instructive post. I have thought about putting in a sprinkling system for my garden but what a PITA it would be to get a pipe deep enough that it wouldn't freeze.
Thanks.
My brother ran a huge community garden in a small town in the mountains of Western Montana and had an automatic sprinkling system and a big stainless steel sink right in the middle of the garden for washing roots. I wish he were still alive so I could ask him how he managed it. I'm going to guess that he just attached hoses in spring and removed them before winter. I remember that winter -- a mild one by all accounts -- to have lows that hovered around 0°.
