Hi All,

I have a huge Hollyhock growing next to my gas meter up
against the cement foundation of my house (wood floor
house with crawl space). Does this Hollyhock present
an kind of danger to either 1) the gas meter, 2) the gas
pipes, and/or 3) the foundation of my house?

Hollyhock has a long tap root with short side roots.
The roots aren't a danger.
