Georgetown homeowner guide · Updated July 2026
Georgetown's live oaks are the county's oldest and most protected — which makes the pruning calendar, cut-sealing discipline, and Sun City's mature-canopy needs the local rules that matter.
Georgetown's canopy is its inheritance — Old Town's heritage live oaks predate the neighborhoods around them, and Sun City's mature plantings are entering the decades where professional care decides their next fifty years. The stakes are set by oak wilt, the fungal disease that kills live oaks through root-connected networks: here, when you prune matters as much as how.
The safe pruning windows for oaks are July through January — avoid February through June, when the sap-feeding beetles that spread oak wilt are most active and fresh cuts are open invitations. Every cut on any oak, in any season, gets pruning paint immediately; it's the one tree species where sealing cuts is standard practice, and a crew that doesn't carry paint for oak work is telling you something. Trenching between infected and healthy trees is the containment tool when the disease appears nearby — an arborist conversation, not a chainsaw one.
Old trees need structure work, not volume removal: dead-wood clearing (the ice-storm insurance), roofline clearance cut to the branch collar, and canopy thinning that never exceeds a quarter of live growth. The local reviews document the right instincts — minimal-removal pruning framed around tree health, and companies that explain cuts before making them. What mature oaks never need: topping, lion-tailing, or the flush cuts that invite decay. Any crew proposing to "top" a live oak should be thanked and dismissed.
Written scope naming each tree and the work on it, proof of liability insurance (tree work is the trades' highest-risk category — verify, don't assume), oak-wilt-aware practices stated plainly, and cleanup included. ISA-certified arborists earn their premium on diagnosis, preservation decisions, and anything touching heritage trees; production trimming crews are fine for routine clearance. For removals near structures, ask how the tree comes down — rigging and section work, not felling — and confirm stump grinding is in the quote or priced separately.

July through January is the safe window — February through June is peak oak wilt transmission season. Whenever you cut, paint every oak wound immediately. Non-oak species can be pruned on their own schedules.
Yes — it's active across Central Texas and spreads through root networks between live oaks, which often share roots in older neighborhoods. Prevention is cheap: paint cuts, prune in-window, and get an arborist opinion fast if a neighbor's oak browns suddenly in summer.
For routine clearance, a well-reviewed crew is fine. For heritage trees, disease questions, preservation decisions, or anything you'd grieve losing — pay for ISA-certified judgment first, then let the crew execute the plan.
