i have 2 white cedar trees (tuja tree) in the middle of my garden in montreal. they are appr. 10 years old, were there when i bought the house. the plot is long 30 m and large 10 m, the cedars are just in the middle, 5 m one from the other. for the last 5 years i am trying to grow something, and results are less than spectacular. the location is good; i blamed it on the clay soil, and tried the raised beds for vegetables last summer. every new bed or raised bed or bottom-less container gets invaded by the very fine rootlets of the cedars. i wonder if there is any way of containing the cedar roots, or i just have to get rid of them. it will break my heart, they are really beautiful. can they get into the sewer pipes, or i'm getting paranoic now.
Yes: Arborvitaes will get into pipes that have openings where they can enter. The remedy is to replace the pipes. Penetration of planting beds can be corrected by installing a root barrier. http://www.google.com/search?q=root...s=org.mozilla:en-US:official&client=firefox-a
