Trees & Soil Depth
For trees that require depth for a tap root to withstand storms, the following list may help narrow your choices...especially if you live in an area where soil depths may be fairly shallow. In areas with caliche or inpenetrable hardpan, planting these tree could be an exercise in frustration. However, where soil is deep enough these trees will live a very long time because they can tap water sources that enable them to be sustained even during periods of drought.
This list is biased toward trees grown in moderate climates so check with your nursery for varieties that might be intolerant of particularly cold climates.
