Question: poplar roots
Hi some time ago I planted a poplar a few meters from home. Now it has grown a lot and the roots have spread considerably. This phenomenon has meant that a wall made of small holes is rising and breaking. Now the question is related to the perimeter wall of the house. I state that all the perimeter wall what is underground is of reinforced concrete. Above the house was built. COULD THESE ROOTS DETECT THE WALL INQUESTION ??
Answer: poplar roots
poplars are trees that can reach considerable heights, and quickly produce a large root system, which can extend up to 10-15 meters around the plant; these are not destructive roots, as is the case for example for the roots of sea pines, because the roots of poplars tend to develop downwards, in depth. The fact that the roots have raised a wall, however, indicates that your poplar is finding an excessively compact soil, and has begun to extend its root system even on the surface. This fact should not cause you to worry, because the roots of these plants tend to bypass obstacles, and not to cross them; this means that if they collide with the reinforced concrete structure of the house, they will simply begin to develop deeply, without affecting the foundation of your home in any way. Also in the case of the wall, it is probably a structure without foundations, under which the poplar roots pass: obviously the passage of the roots has caused micro displacements of the wall, which has cracked as it is not able to absorb these movements , albeit of a small entity. In many areas of Italy, poplars are planted along road avenues, even in areas where the houses are actually located a few meters from the trunk of the poplars, and I have never heard of houses ruined by their roots. plants. Very often I have heard instead of poplar roots that grow on the surface, ruining walls, paths, paving; to overcome this problem it is usually advisable to work the soil around the stem well, so that the plant is invited to develop deeper roots, which do not in any way damage existing structures. When the damage done by the roots to the surface structures is considerable, we try to identify the roots, digging and cutting them, in order to invite the tree to produce new ones: having found an obstacle that even ruined the roots , in the following years it will tend to develop its roots in another direction, avoiding stone walls and paving. Others tend to remove the surface roots of the poplar, to invite the plant to produce a deeper root system.
