    Weakness equals pests. It’s easier for scales and aphids to strike, because street trees have limited resources they can put toward defending themselves

    These painful injuries show up as small yellow and brown spots on the needles

    What this means is that when trees in urban areas run up against ground as hard as concrete wherever they turn, they get desperate, and it is only as an absolutely last resort that they finally find a way out into sloppily backfilled trenches. Once they get there, they are a problem

    Regardless of species,this is how many social ills are incurred

    The culprit is sentenced to death for its excursion under the sidewalk and into what it thought was paradise. The offending tree is cut down, and its successor is planted in a built-in root cage to discourage such behavior in the future

    An iniquitous tragedy…I have no metaphor for it.

    The roots of forest trees don’t actually grow very deep

    Counterintuitively

    This “pruning” (it’s actually more like a massacre) is often only for aesthetics, which dictates that the crowns of trees lining a walk or driveway are all the same size and shape

    the care simply stops

    A myopic and irresponsible cosseting

    lovingly cared for and watered

    when the roots are pruned, the brain-like structures are cut off along with the sensitive tips. Ouch! After that, it is as if this interference makes the trees lose their sense of direction underground. They stop growing roots down into the soil and form a flat plate of roots near the surface instead, severely restricting the trees’ ability to find water and food

    The mechanics of planting also haunt the trees for the rest of their lives

    the soil is a complete disaster
