Spring in Arlington arrives on the wind, with May thunderstorms marching in from the west and bending the old pecans and post oaks that shade the city's older streets. When the sky clears, the canopy shows what it is made of, and each tree tells you whether anyone has looked after it. Wright Tree Service tends that canopy for Arlington properties with trimming and pruning that open a crown to the light, clearance for limbs hanging over roofs and driveways, and removal when a tree's time has come. Done well, pruning leaves a tree looking less touched, not more, as if it had simply grown into a better shape. Stand beneath a carefully kept pecan in high summer and the shade feels like a room the tree built for you.
