Local know-how
What we see in Thornton yards
Thornton has grown steadily north of the city. The older neighborhoods toward the south end have mature trees, many planted in the 1950s and 1960s, that now need regular pruning and sometimes removal. Much of the rest of Thornton is newer, with young trees that benefit from structural pruning while they are small.
Emerald ash borer has been detected in Thornton, and ash trees are common in older yards and along streets. If you have one, an inspection tells you whether to treat it or replace it. When you replace a tree, choosing a species different from the rest of the street helps protect the neighborhood from the next pest.
The open plains around Thornton bring strong wind. Young trees planted too deep or left staked too long often lean or snap. We plant at the right depth and remove stakes after the first year, so trees grow their own strength.

5 out of 5 stars
They helped us pick a tree that will not grow into the power line, planted it at the right depth and left a watering schedule on the fridge. It leafed out well this spring.

A spring snow dropped a huge limb onto our garage roof late at night. They came out once the snow eased in the morning and lifted it off in sections. Took longer than I hoped, but they told us why.

The arborist checked our two ash trees and was honest that the small one was not worth treating. We injected the big one and replaced the small one with a different species. Clear prices for both.
