Ficus nitida are amazingly well suited for this climate. I would have never guessed. They can brown out in bad winters. 2003, 2007, 2011, 2013 come to mind in my Arizona history. However, 100% green in PHX all the other winters. And even after a brown out, you prune them, water them and the recovery is well underway by late spring.
More importantly, every summer they handle the otherworldly summer highs and rough sun. Yuma, AZ, which averages just over 2" of a precip. a year has some of the largest Ficus nitida in the country. Certainly these are irrigated. Yet remove Ficus from PHX, Yuma and Palm Springs, and you lose one of the biggest producers of the color green in the cultivated landscape.
They truly blow my mind.
What's more surprising, here, their roots are remarkably friendly for such a large tree. Mesquite roots buckle sidewalks, shift block walls and irrigation pipes. Quite frankly, Mesquites are a nasty tree in cultivation. Better suited for large open spaces. I had to repair my mom's block wall because of Mesquite. Yet I've seen Ficus drop their roots deep here, probably to escape hot surface soils, they leave bricks planted around them intact more often than not. This is not the cause in coastal CA where the soil temps remain a lot friendlier.
I could go on and on about Ficus. So I'll end it now!
