|I have a spot in my front yard in which I'd like to plant a lilac bush. |
How deep do lilac roots go since there is a sewer line from my house to the street approximately six to seven feet under ground level. Will the lilac roots interfere with that line? Thanks.

|Roots from a lilac bush will generally remain in the top 18-24" of soil but they may spread out a bit (it's a natural tendancy for these plants to colonize an area). I wouldn't be at all concerned that lilac roots might invade a sewer line that is 6-7 feet deep.|
