Dave Dexter and his crew from DEXTER estate landscapes moved this huge Valley Oak we grew to a Windsor, Sonoma County golf course from our growing ground at Main Street Trees in Napa. The lobata grew from an acorn that fell from the old trees on our property. This tree was about 15 years old. Valley Oaks are the most appropriate oak tree for our area with clay soil on the valley floor, although Coast Live Oaks grow great here too.
