I have three Ficus Elastica in my front porch very close to the house foundation (2-3 feet). I have seem some comments about how agressive their roots are. In fact there are two big roots (1" thick) coming out of the planting bed were they are. Should I be concern about possible structual problems in the foundation, sidewalks, water, sewer lines, etc. due to their roots.? Should I move them to the backyard, 20-30 feet away from the house? Thanks in advance for the advice.
I would be more concerned that the plants will grow to about 30-40' and are probably not suitable for planting in front of a house porch. Best to move them while you can to a more suitable location. Proper pruning will help strengthen the plant, but try to site in a somewhat sheltered location as F. elastica are susceptible to wind damage. Here's some more info on the plant: http://hort.ufl.edu/trees/FICELAA.pdf
Depending on where you are in Houston, you may not have to worry. F. Elastica is zone 10a+ and we're in 9a -b. That being said, if it does survive, you may have quite the chore keeping up with the aeriel roots that, if left unchecked, will cause you problems... Unless, of course, you don't mind roots penetrating the roof and entering the living room through the ceiling... Could be a nice decorative touch. ;-)
