Magnolia Teddy Bear – Root System

Question

Hi, I have a Magnolia – Teddy Bear Tree approx six metres high ( hopefully it has reached maturity ) I is situated approx one metre from a brick retaining wall The wall is approx two and a half metres high and approx twenty cm thick. Having said all this- is the root system of a Magnolia Teddy Bear considered invasive ? In my situation do you think i have any concerns moving forward regarding the root system damaging the retaining wall ? The Magnolia was planted approx five years ago. I would appreciate your advise. Thank you Regards.

That is close to a structure for any tree to be planted, and Southern magnolias are known for their horizontal, rope-like roots. If planted near the house, plumbing pipes could be an issue. However, 'Teddy Bear' is a much smaller variety of magnolia. I did see in one reference that the chance of root damage was low. Another reference even suggested planting in front of retaining walls and fences, so it should be okay. Here is more:
