In the garage there were 2, 10' diameter, floor to ceiling plastic clam-shell growing units.  

If I don't keep it under control, it will take over the yard.Some of the canes are about 4 inches in diameter, and probably 20-30 feet tall.

If you have roots that have grown to a larger diameter, it has been a much longer term issue that can easily break a lot of pipe, making it un-serviceable.

I use upgraded drywall anchors (rated 50 lbs), rods that are 1" in diameter, and then pick up grommeted 84" or 96" curtains/drapes from a local charity shop or amazon.

(This was an old house which originally had a septic field—this pipe was cast iron and was larger than any I had at any other house—I recall it was ~8 inches in diameter).

The fragrant flowers appear in mid-spring to early summer and are often six to ten inches in diameter.

One of the trees we removed was almost 4 feet in diameter at the base, and only 6 feet from the house.
