Our company can provide oak tree trimming from the months of November through the end of March. This is the optimal time for oak trees to be trimmed as recommended for those of us that reside in the state of Ohio. Our company can certainly provide an estimate any time of the year for oak tree trimming, but ultimately advise that these trees be trimmed in the time frame recommended for the health and vitality of the tree long-term.
