Does Photinia have aggressive root systems
I am considering using Photinia as a tall screening hedge on the western side of my pool fence but need to know if they have an aggressive root system that might compromise the integrity of the pool and surrounding concrete.

Photinia does not have what is considered an aggressive root system. It generally has more shallow roots. Care needs to be taken planting any shrub or tree near foundations, well, septic systems and pools.
I would consult a pool expert to the spacing of plantings that would be a safe distance from the pool.
Here is a link with growing information.
