Preparing trees for hurricane season

Updated · Guide by TreeRemovalServices.net

Short answer

Prepare trees in the months before hurricane season (June 1 in the Atlantic): remove dead wood and hangers, have weak or decayed trees near the house assessed, and have dense crowns structurally pruned by a qualified arborist. Don't top trees or strip palms. Over-pruned trees fail more, not less.

Before the season

  • Have trees within reach of the house inspected for decay, cracks and weak unions.
  • Remove dead branches and any trees that are dead or failing.
  • Structurally prune young and mid-age trees to a single strong leader.
  • Thin dense crowns lightly, never more than needed.
  • On palms, remove only dead fronds, fruit and flower stalks.

Species differences

University of Florida IFAS research after the 2004–2005 hurricanes found that species vary widely in wind resistance. Live oak, sabal palm, southern magnolia and bald cypress were among the more resistant, while laurel oak, water oak, sand pine and Bradford pear were among the less resistant. Planting choices matter for the next storm.

Warning signs worth fixing before the season

These are the defects most likely to turn into failures in hurricane-force wind:

  • Dead trees or dead tops within reach of the house
  • Trunks with cavities, cracks, or mushrooms at the base
  • Multiple trunks joined in a tight V with bark pinched between them
  • Trees with roots cut by driveways, pools, or utility trenches
  • Trees suddenly exposed after neighboring trees were removed
  • Palms with dead, hanging fronds or heavy coconut clusters

When a storm is forecast

It's too late for major pruning. Tree crews are booked, and fresh cuts don't help. Secure loose items, clear gutters and drains, park cars away from large trees, photograph your trees and house for insurance, and know how to shut off utilities. Afterward, follow what to do after a storm.

Florida counties including Miami-Dade and Martin ask residents not to start any pruning once a hurricane watch or warning is issued (the Miami trimming calendar lays out the dry-season window). Cut branches piled at the curb can't all be collected before landfall, and they turn into wind-borne debris.

A pre-season calendar for Gulf and Atlantic coast yards

Atlantic hurricane season runs from June 1 to November 30, with most landfalls from August through October. Working backward from that gives a simple schedule:

Winter (December to February)

What to do
Have trees near the house inspected; book structural pruning and removals
Why then
Crews have openings and deciduous trees are bare, so defects are easy to see

Spring (March to May)

What to do
Finish pruning, remove dead trees, trim palms
Why then
Cuts made now have weeks to start closing before storms, and debris pickup runs normally

Early season (June and July)

What to do
Remove only dead wood and hangers that show up
Why then
Heavy pruning now stimulates soft regrowth just before peak season

Peak season (August to October)

What to do
Walk the yard after each storm; photograph changes
Why then
New cracks and leans show up after storms and saturated soil

Wind-firm roots: water, soil and construction

Most trees that blow over in hurricanes fail at the roots, often in soil saturated by rain that fell before the strongest wind arrived. Some of the root risk is set long before the season starts.

  • Roots cut on one side for a driveway, pool, trench or addition leave the tree anchored mostly on the other side. Trees with major roots cut in the last few years deserve a closer look.
  • Trees growing in narrow strips between pavement have a small root plate for their size.
  • Shallow soil over rock, common in South Florida, limits rooting depth and anchorage; it's one reason big ficus near seawalls in Fort Lauderdale deserve a pre-season look.
  • Trees suddenly exposed when neighboring trees or a woodland edge were cleared haven't adapted to wind from that side.
  • Don't add fill soil over the root zone or park equipment there before the season; compaction and buried roots weaken anchorage.

Common questions

Should I cut down big trees before a hurricane?

Not healthy, well-structured ones. They often shelter a house from debris. Remove trees that are dead, decaying or structurally failing, based on an assessment.

Does thinning a tree make it hurricane-proof?

No. Light, selective thinning can reduce wind load on a dense crown, but no pruning makes a tree storm-proof. Removing too much foliage, or stripping inner branches, makes limbs more likely to break.

Can I trim trees after a hurricane watch is issued?

Coastal counties ask you not to. Fresh cuttings can't be collected before landfall and become flying debris. Only pick up loose branches and secure outdoor items once a watch is posted.
