I have two lovely old magnolia trees around my house. The trees are quite large, and I assume quite old. This winter, some of the pipes had to be worked on, and some of the work was done around my trees. I was told that it was necessary to cut off some of the roots from both trees in order to put in new pipes right between the trees. The roots cut off were fairly thick (up to 3 inches) and within couple of feet from the tree trunks. I am very concerned that too much was cut off, and that my trees might now be damaged. I was wondering if the trees can recover from such drastic operation, and whether the trees have enough root support. I worry that with the strong enough wind, if the trees are not rooted properly, they may collapse onto the house. Any advice would be greatly appreciated. I already read advice provided on page 2 regarding magnolia tree roots, but I was wondering if anyone has anything to add. Thank you.
