Most street trees are in the process of dying young, yet over 60% of the city’s tree budget is devoted to them (Hauer & Peterson). You’re like a battlefield doctor: watching street trees die before their time, cutting off dead limbs, giving trunk injections to slow, deadly diseases, cleaning up collapsed heart-rot trees, girdling roots or cut roots from sidewalk and roadwork, removing stubs and overcoming old flush cuts.
City trees have to be maintained, just like other infrastructure, over their entire lifetime. The challenge is to give trees the maintenance they need when they need it. If done right, this will reduce overall maintenance costs by huge amounts (Shigo). (2015) (November) by L. Peter MacDonagh on Deep Root.
