Live oak pruning that keeps a 300-year tree standing
The Duffie Oak has stood in Midtown for about 300 years. Live oaks survive hurricanes that flatten pines, which is why the risk is never the whole tree. It's one long limb over the roof, a hollow fork, or a crew with a chainsaw and no plan.
The southern live oak is why people fall in love with Mobile. The Duffie Oak, the city's oldest living landmark, is roughly 300 years old, 30 feet 11 inches around at chest height and 126 feet across, recognized by the Alabama Forestry Commission as a famous and historic tree. The University of Florida's hurricane research lists the native live oak as a survivor species, and after Sally you could see why: the oaks along Government Street were still standing while pines were on roofs across the county. A live oak is low, wide, dense-wooded and deep-rooted. Left alone in the right spot, it outlives the house.
The trouble starts with the limbs. A live oak grows horizontal limbs that can run 40 or 50 feet and weigh more than a car, and over decades they reach over the roof, the driveway and the street. Pruning a live oak is about managing that weight and that reach without wounding the tree: deadwood out, clearance over the roof and the street, reduction cuts at the ends of over-extended limbs to bring the weight back toward the trunk, and small, well-placed cuts that the oak can close over. What it is never about is topping, lion-tailing (stripping the interior and leaving tufts at the ends, which makes limbs more likely to break, not less) or cutting flush to the trunk. The resurrection fern and Spanish moss stay; neither one hurts the tree.
Timing matters less for live oaks than for most trees, but late winter, before the spring flush, is the best window for heavy work, and the months before June 1 are when hurricane-prep thinning should be done. The permit matters too. A live oak on the street side of the sidewalk is a City tree and needs a Mobile Tree Commission permit to prune; inside the historic districts, any oak of 8 inches or more is a Heritage Tree and needs one; and the permit requires the work to be done by a certified, licensed and bonded arborist. Our ISA Certified Arborist writes the pruning plan, we pull the permit when one applies, and the cuts are made by people who understand what they're standing in.
What's included
Arborist's pruning plan
An ISA Certified Arborist walks the tree with you, marks what comes out and why, and puts it in writing.
Deadwood and clearance
Dead limbs out, clearance over the roof, gutters, driveway and street, with cuts placed where the oak can close them.
Weight reduction, not topping
Reduction cuts at the ends of over-extended limbs bring weight back toward the trunk. We never top or lion-tail a live oak.
Fern and moss left alone
Resurrection fern and Spanish moss are harmless. They stay.
Permit handled
Right-of-way oaks and Heritage Trees in historic districts need a $75 Tree Commission permit and a certified arborist. We do both.
Cleanup and photos
Brush chipped and hauled, the lawn raked, before-and-after photos the same evening.

Questions we get about live oak pruning
Do I need a permit to prune my live oak?
If it's on the street side of the sidewalk, yes, from the Mobile Tree Commission. If it's inside a historic district and 8 inches or more across, yes. On a developed lot outside a historic district and off the right-of-way, no. On an undeveloped lot, a live oak of 18 inches or more needs one. It's $75 per tree and we apply for it.
When is the best time to prune a live oak?
Late winter before the spring flush is best for heavy pruning, and any time before June 1 for hurricane-prep thinning. Deadwood can come out any month. Avoid heavy pruning in the heat of July and August if it can wait.
How much can you take off at once?
Less than people think. Removing more than about a quarter of the live canopy stresses the tree and pushes out weak sprouts. If a limb over the roof needs more than that, the answer is reduction cuts now and a second pass in a year or two, or a cable.
Should I have the Spanish moss removed?
No. Spanish moss and resurrection fern take nothing from the tree. Heavy moss can add weight on a limb that's already over-extended, and in that case the fix is the limb, not the moss.
The live oak is lifting my driveway. Can you cut the roots?
Carefully, and not many. Cutting roots on more than one side of a live oak, or close to the trunk, is how a survivor species becomes a hazard. We'll look at it with you; often the better answer is a driveway repair that bridges the root.
Can you cable a split fork instead of removing the tree?
Often, yes. A co-dominant fork with a crack can be braced with a steel rod and the limbs cabled above it, which takes most of the risk out without losing the tree. It needs to be inspected every few years.
