Tree care in Miami runs on two seasons, not four. The dry months from November through April are when you prune, plant, and fix problems.
The wet months from May through October are when trees grow fast, fungus spreads, and storms arrive.
Most yard damage I see traces back to work done in the wrong half of the year.
What the Dry Season Checklist Looks Like, November Through April
The dry season is your work window. Cooler air, less rain, and slower growth mean a tree recovers faster from cuts and transplanting.
November and December
Walk the yard after the first cool front.
Look up at every large tree and note dead branches, cracks where limbs meet the trunk, and any lean that changed over the summer.
Storm season just ended, so damage is fresh and easy to spot.
This is also the best stretch for planting. Roots get months to settle before the heat returns.
The best time to plant a tree in South Florida is not spring, which surprises people who moved here from up north.
January and February
Do your structural pruning now. This means removing crossing branches, thinning a crowded canopy, and shaping young trees. Cuts made in cool, dry weather close faster and invite less disease.
Watch for the signs a tree needs pruning rather than trimming on a schedule. A healthy live oak may not need touching for two or three years.
A fast-growing ficus might need attention twice a year.
March and April
Fertilize now if a soil test says the tree needs it. Mulch out to the drip line to a depth of 2 to 3 inches, keeping it off the trunk, as UF/IFAS Extension recommends for Florida yards.
Mulch piled against bark holds moisture and rots the base.
Finish any large removals before May. Crews book solid once storm warnings start.
How Wet Season Tree Care in Miami Changes the Job, May Through October
Wet-season tree care in Miami is mostly about inspection and restraint.
Heavy pruning in June opens fresh wounds during the very months when fungal spores travel most effectively.
May
This is the deadline month. Get wind pruning done before June 1. Thinning the canopy lets air pass through instead of pushing against a solid wall of leaves.
Full hurricane season preparation also covers clearing weak limbs over the roof and driveway.
Also check for hollow spots at the base. Tap around the trunk with a mallet. A dull, drum-like sound can mean decay inside.
June Through August
Watch, do not cut. Trees are putting on their fastest growth now, and so are the problems.
Look for these each month:
- Dark, sunken patches on bark, which often signal fungal infection.
- Mushrooms growing at the base or on surface roots.
- Standing water sitting around the trunk for more than a day.
- Sudden yellowing on one side of the canopy.
Bark that changes color is worth a closer look, since dark spots on tree bark can indicate sooty mold, a wound, or something worse beneath the bark.
Pests get busy too. Scale, borers, and weevils all peak with the heat, and pests and diseases kill trees faster in a wet summer than in any other season.
September and October
These are the highest risk weeks for hurricanes in South Florida, according to the National Hurricane Center.
Keep pruning light. Remove only hanging limbs and obvious hazards. Save the shaping work for December.
After any tropical storm passes, walk the yard again. Look for fresh soil cracks around the root plate. A tree that shifted in saturated soil may look fine yet remain unstable.
Which Tasks You Can Skip Entirely
Not every step in a generic tree care calendar applies here. Skipping the wrong ones costs money for no benefit.
Wrapping trunks for winter does nothing in Miami. Neither does dormant oil timing built around a freeze, since our trees never fully go dormant.
Topping is not maintenance. Cutting a canopy back to stubs makes a tree weaker and produces fast, poorly attached regrowth that snaps in the next storm.
Annual fertilizing is also unnecessary for most established trees in Miami yards.
Mature trees pull plenty from the soil once roots are established, and extra nitrogen just pushes soft growth that wind tears off.
When the Calendar Stops Being Enough
A checklist handles routine care. It does not handle a leaning trunk, a limb over a bedroom, or roots lifting a driveway slab.
Those need eyes on the tree, not a date on a page.
If you spot fresh cracks, sudden canopy dieback, or a tree that moved after a storm, call a professional that week rather than waiting for the next season.
Anyone comparing tree service in Miami should ask when the work is best scheduled, because a company that books your heavy pruning for July is telling you how much it knows about this climate.
