Ficus between retaining wall and pool
I am looking for any resources that support that a ficus has an invasive root system and would not be an appropriate choice for planting in a 5 foot area that is bordered by a swimmming pool and retaining wall. I have a nursery that recommended and planted 4 ficus trees in this area. Having just moved to AZ from the midwest, we took their recommendation and let them plant them. Only by having someone come out to do yard clean up for spring did we have it called to our attention that this could be a huge problem. In addition, the soil is very hard and rocky and required a hard dig for the pool.
