I recently purchased a home which has a big conical shaped Giant Sequoia in the yard. It is 30 feet tall and very healthy looking. It is about 16 years old. I live in Prescott, AZ at about 5800 feet elevation. Soil is mostly volcanic/granite and well drained. Climate is high desert with only about 14 inches of water annually. We get about a foot of snow each year with highs in the low 90’s and lows in the teens. The climate is ideal most of year, 350 days of sun each year. Thanks to Bill White for sending us this picture.
