|I was wondering if you could recommend a tree for an area of my yard. I live in Walnut Creek, CA - hot and dry (although I will irrigate) in the summer (80-100 degrees F) and can get as low as 25 degrees F over the winter. Clay soil, but well supplemented. The location is along a west-facing fence, good sun, about 10 feet wide by 30 feet long, near a swimming pool (about 10 feet from the pool). I would like to have trees roughly 40 feet tall (not too tall as they will dwarf the yard) to screen a possible 2-story house in the neighboring lot. I like the liquidambar trees (very nice light green color and wavy leaves in the wind)- these trees grow well in the area and would look nice. But I am concerned they might get too big and their roots might damage the pool. I also like ornamental pear, but both of my pear trees contracted fireblight and were destroyed. I'm not fond of the Italian cypress. Any suggestions?
