I have a landscape customer who is asking me about irrigation options and there is an issue regarding a Tree. This is a fairly small front yard and one section is bordered by the parkway sidewalk, entry sidewalk, property line and the house. This entire section is has roots from a big Silver Leaf Maple probably 12 years old. If you've seen these mature trees they have major surface roots. So as an irrigator would you: a: trench through the roots and irrigate with sprays b. avoid trenching the roots and use rotors or c. move to the next job.
