Hi, Ive got some land in Cuyama valley CA, which is in the north east part of Santa Barbara county, which I would like to live on in a few years. the problem is that there is no well on the prop, and the valley is quite arid, 1-1.5 feet of rain per year, with a couple inches of snow as well. otherwise it is hot and dry. Though I would like to plant some trees now, so that in a few years when I have money to dig a well and move out there I will already have shade. as of now, there are is only tumbleweed and juniper bushes. are there any trees that will grow in these conditions without considerable water supplement?
