Oakdale residents were left flabbergasted when the trees that line their streets got a dramatic prune by council workers.
Many took to Facebook to voice concerns when many of the trees were completely cleared of leaves and branches.
But a Caerphilly County Borough Council spokesperson tried to reassure residents that the work, known as pollarding, is a traditional way of maintaining certain tree species.
The spokesperson said: “Although initially quite dramatic in appearance, these works are not detrimental to the trees and they will begin to regenerate new growth very swiftly.
“Once a tree has been pollarded it is good practice to repeat the process on a regular basis to control the growth rate and size of the trees.”
