I live in Washington, and P. Vivax grows to large sizes here. I got a new plant and I'm not sure where to plant it. I want to use it as a screen and grow a grove, but I don't know if there's any danger growing it near the house or cars. Do they topple or break and are they heavy? I'm considering planting on this little terrace 5 ft off the ground that's surrounded by concrete on two sides to effectively prevent root spread, but it's right by the house. These suckers grow tall and I don't know if I should be elevating them.
Another place I can plant them is in a back filled koi pond surrounded by 20ft pines but it's right by the road and power lines which are about 20ft away. Any suggestions?
