question: I love my Jacaranda tree. We suspect roots are reaching into the plumbing and causing problems. Also seems like the root system is expansive and going below the concrete drive way. What type of root systems do Jacarandas have and can they be the culprits of such damage? I dont want to remove the tree on speculation. Also, once tree is removed is it possible roots will grow back and cause the same problem even without the tree? Thank You for your help!

 

Answer:  Hi Marcy, It all sounds like nonsence to me. I have no idea what “plumbing” means. It is very rare for any plant or tree to attack properly constructed water suppy pipes. Sometimes water-loving plants will grow into already-leaking (ie badly constructed) drainage or sewerage pipes. In general, jacarandas do not cause trouble with their roots, but any plant can do some damage, particularly if poor construction is involved. Note down the name of the person who warned you about the root problems and put it on the refrigerator headed up:’Not to be trusted”.  Don
