By the time this article publishes, we will be more than 70 days since Hurricane Michael toppled or damaged an incredible number of trees in the Panhandle. Enormous piles of once stately shade trees line the streets in neighborhoods and business districts in. The cleanup efforts have been phenomenal, over 4 million cubic yards of storm debris picked up in Bay County to date, but there is still a long way to go in the recovery process.
So, as gardeners, how can you help our community get back on track amidst your own struggles to recover? A few Florida Friendly Landscaping™ Principles come to mind.
- #1 Right Plant, Right Place – as you rebuild your landscapes, make sure to choose the appropriate plant for the location. Consider mature size and give those plants space to thrive!
- #4 Mulch – do you have bare ground that will eventually become landscape beds or turf but no resources or time to replant yet? Consider mulching the area to keep soil from eroding and to help improve soil though decomposition of natural products. Hint – see Recycling for free sources!
- Mulch tips https://sfyl.ifas.ufl.edu/media/MulchBrochure.pdf
- keep mulch 12 inches from tree trunks
- recommended depth in beds or under dripline of tree canopy (excluding within 12” of trunk) is 2-3 inches
- leave an 18-24 inch buffer around building foundations mulch free to reduce conducive termite conditions

#7 Recycle – driving around town I have seen some really creative uses for stumps, trunks, and branches that homeowners have constructed and messages of hope that bring a smile to my face. Another method of recycling is to use the chipped vegetative debris as mulch, either available as “utility mulch” by cities and counties or you may have some in your own yard right now.
- Utility mulch does come with some words of caution because there is an increased risk of introducing weeds to your landscape with untreated storm debris. However, if you need mulch for pathways or planting beds you will be helping your community’s cleanup effort by reducing waste accumulation. Just watch for “volunteer” plants and manage as needed.
In Bay County, there are 4 locations where you can load and haul off your own utility mulch from storm debris
- Under the Oaks Park – 5843 E. U.S. 98, Panama City, FL 32404
- G. Harder’s Park – 8110 John Pitts Rd., Panama City, FL 32401
- Chapman Park – 2526 Rollins Ave., Bayou George, FL 32404
- Laird Park – 6310 Laird Park Rd., Panama City, FL 3240
For sources in your county, check with your Solid Waste Department for utility mulch availability.
After a devastating windstorm, as we just experienced in the Panhandle with Hurricane Michael, people have a tendency to become unenamored with landscape trees. It is easy to see why when homes are halved by massive, broken pine trees; pecan trunks have split and splayed, covering entire lawns; wide-spreading elms were entirely uprooted, leaving a crater in the yard. However, in these times, I would caution you not to rush to judgement, cut and remove all trees from your landscape. On the contrary, I’d encourage you, once the cleanup is over and damaged trees rehabilitated or disposed of, to get out and replant your landscape with quality, wind-resistant trees.
First, it’s helpful to take a step back and remember why we plant and enjoy trees and the important role they play in our lives. Beyond the commercial aspect of farmed timber, there are many reasons to be judicious with the chainsaw in the landscape and to plant anew where seemingly sturdy trees once stood. For example, trees provide enormous service to homes and landscapes, from massive cooling effects to aesthetic appeal. Take this thermal satellite image of Hurricane Michael’s path that simultaneously shows the devastation of a major hurricane and the role trees play in the environment.

In the lighter colored areas where the wind was strongest and catastrophic tree damage occurred, the ground temperatures are much higher than the unaffected areas. Lack of plant life is entirely to blame. Plants, especially trees, provide enormous shading effects on the ground that moderate ground temperatures and the process of transpiration releases water vapor, cooling the ambient air. Trees also lend natural beauty to neighborhood settings. There is a reason people termed the hardest hit areas by Michael “hellscapes”, “warzones”, etc. Those descriptions imply a lack of vegetation due to harsh conditions. In this respect, trees soften the landscape with their foliage colors and textures, create architecture with their height and shape, and screen people from noise, unpleasant sights and harsh heat.
Though all trees give us the benefits outlined above, research conducted by the University of Florida over a span of ten major hurricanes, from Andrew to Katrina, shows that some trees are far more resistant to wind than others and fare much better in hurricanes. In North Florida, the trees that most consistently survived hurricanes with the least amount of structural damage were Live Oaks, Cypresses, Crape Myrtle, American Holly, Southern Magnolia, Red Maple, Black Gum, Sycamore, Cabbage Palm and a smattering of small landscape trees like Dogwood, Fringe Tree, Persimmons, and Vitex. If one thinks about these trees’ growth habits, broad resistance to disease/decay, and native range, that they are storm survivors comes as no surprise. Consider Live Oak. This species originated along the coastal plain of the Southeastern United States and have endured hurricanes here for several millennia. Possessing unusually strong wood, they have also developed the ability to shed the majority of their leaves at the onset of storms. This defense mechanism leaves a bare appearance in the aftermath but allows the tree to mostly avoid the “umbrella” effect other wide crowned trees experience during storms and retain the ability to bounce back quickly. Consider another resistant species, Bald Cypress. In addition to having a strong, straight trunk and dense root system, the leaves of Bald Cypress are fine and featherlike. This leaf structure prevents wind from catching in the crown. Each of the other listed species possess similar unique features that allow them to survive hurricanes and recover much more quickly than other, less adapted species.
Laurel Oak split from weak branching structure.
However, many widely grown native trees and exotic species simply do not hold up well in tropical cyclones and other wind events. Pine species, despite being native to the Coastal South, are very susceptible to storm damage. The combination of high winds and beating rains loosens the soil around roots, adds tremendous water weight to the crown high off the ground, and puts the long, slender trunks under immense pressure. That combination proves deadly during a major hurricane as trees either uproot or break at weak points along the trunk. In addition to pines, other widely grown native species (such as Pecan, Laurel Oak and Water Oak) and exotic species (such as Chinese Elm) perform poorly in storms. Just as the trees that survive storms well possess similar features, so do these poor performers. We’ve already mentioned why pines and hurricanes don’t mix well. Pecan, Laurel Oak, and Water Oak tend to have weak branch angles and break up structurally in wind events. The broad spreading, heavy canopy of trees like Chinese Elm cause them to uproot and topple over. It would be advisable when replanting the landscape, to steer clear of these species or at least site them a good distance from important structures.
This piece is not a warning to condemn planting trees in the landscape; rather it is a template to guide you when selecting trees to replant. Many of our deepest memories involve trees, whether you first climbed one in your grandparent’s yard, fished under one around a farm pond, or carved your initials into one in the forest. Don’t become frustrated after a once in a lifetime storm and refuse to replant your landscape or your forest and deprive your children of those experiences. As sage investor Warren Buffett once wisely said, “Someone is sitting in the shade today because someone planted a tree a long time ago.”

When there is so much to do in cleaning up after a storm, sometimes we tend to do too much so that it can all get done. Be safe, don’t add to the disaster.

Here are some suggestions:
- Take breaks and rest often. Mistakes happen when people are exhausted.
- Only lift what you can comfortably handle, lifting with your legs and not your back. Get a buddy to help with heavier objects or wait until a team or equipment can assist.
- Make sure you are adequately hydrated. Always keep water nearby and take a long drink during your breaks.
- Protect yourself against biting pests such as mosquitoes with insect repellent.
- Wear protective gloves, sturdy closed toe shoes and long pants.
- Have a first-aid kit available for minor injuries.
- Make sure ladders are stable and locked into position.
- If you are using any type of power equipment, especially a chainsaw, make sure someone else is around. And protective gear is a must. Read about details in this article.
As Hurricane Michael was barreling through the Panhandle region, wasp populations were at their highest of the year. Winds and flooding destroyed many of the nests of paper wasps, hornets, and yellow jackets and now wasps may be aggressive as they defend themselves or remnants of their nests. All are capable of multiple stings that are very painful. It is very likely that you will encounter stinging wasps as they scavenge for food and water, as well as seek shelter among debris and exposed trash.
Many people are stung by paper wasps after storms. They are not attracted to traps.
Here are a few pointers to help deal with stinging wasps.
- Try not to swat at wasps flying around or landing on you. You may be less likely to receive a sting if you can flick them off.
- Some wasps are attracted to the sap from broken or recently cut trees. Look before you reach. Wear gloves and other protective clothing when moving debris in case you disturb foraging or nesting activities.
- Wasps are also attracted to sugars and water. Try your best to keep food and drink cans covered. Completely close garbage containers or bags that contain food debris.
- Repellents are not effective against wasps. There are pesticides labeled to spray on smaller paper wasp nests if you find one in a spot close to people’s activity. These are usually aerosol pyrethroids or pyrethrins. Make sure you read the label carefully and use the product as directed.
- Do not use non labeled products like gasoline to manage wasps. This is not only illegal but can be dangerous to yourself and the environment.
- There are traps for yellowjackets that you may purchase or make. These only manage those wasps flying around, not any remaining in a ground nest.
Here is a Do It Yourself Yellowjacket trap from UF IFAS Extension.
- Cut the top 1/3 off your 2 liter bottle so that you have 2 pieces.
- Add a bait (fermenting fruit or beer) to the bottom of the plastic bottle.
- Invert the top portion of the bottle into the base, forming a funnel.
- Hang or place traps so they are about 4 to 5 feet above the ground. For safety, place them away from people.

Hurricane damaged plants should be cared for as soon as possible. Partially uprooted small trees and shrubs should be securely staked in their original positions. Until plants are reset, protect exposed roots and prevent drying. Soil, moist burlap sacks or moist sphagnum moss can be put on exposed roots. Remove damaged roots so the tree can be reset at ground level.
Once reset, trees should be secured. Two or three, four-foot long, 2 x 2 inch wood stakes can usually anchor trees with trunk diameters less than two inches. Stakes should be placed about a foot outside root ball and inserted eighteen inches into soil. Secure stakes to trunk with ties made from wide, smooth material or hose-covered wire. Trees two inches or larger in diameter should be guyed with three or four wires or cables. Guy wires are secured to deeply driven short stakes evenly spaced outside the root ball. Guy wires should be run through rubber hose and secured to trunk at only one level. Mark support wires with bright materials to prevent accidents.
Guy wires should be adjusted several times during growing season to minimize trunk injury. Support stakes and wires should stay in place for one year.
Soil should be filled around root area once the tree is staked into position. Firm around roots to eliminate air pockets and provide support. Excess soil over the normal root area can be damaging. Only replace soil that has been washed or worked away from roots.
In cases where all branches were destroyed, remove the tree. This is especially important for trees such as pine that do not normally regain their natural form. You may be able to keep other trees such as oaks, where strong bottom limbs still exist. However, emerging sprouts from ends of large, cut limbs will be poorly secured to the tree and are likely to fall from the tree during a storm. In addition, decay organisms usually enter these large wounds. Trees and shrubs that lost their leaves from high winds can usually be saved and should resume growth.
Any tree work, including tree removal should be done by a professional arborist, preferably a certified arborist. To find a certified arborist in your area contact the International Society of Arboriculture (ISA) at 217 355-9411 or at http://www.isa-arbor.com/. You also may contact the Florida Chapter of ISA at 941-342-0153 or at http://www.floridaisa.org/.
Reset plants should be watered twice a week and fertilizer should not be applied. Until re-established, fertilizer will be of no benefit and may injure new roots.
Plants exposed to saltwater, including lawns, should be irrigated with fresh water as soon as possible. Apply water more frequently than under normal conditions.

A natural disaster such as Hurricane Michael can cause excess standing water which leads nuisance mosquito populations to greatly increase. Floodwater mosquitoes lay their eggs in the moist soil. Amazingly, the eggs survive even when the soil dries out. When the eggs in soil once again have consistent moisture, they hatch! One female mosquito may lay up to 200 eggs per batch . Standing water should be reduced as mush as possible to prevent mosquitoes from developing.
You should protect yourself by using an insect repellant (following all label instructions) with any of these active ingredients or using one of the other strategies:
- Oil of lemon eucalyptus
- Para-menthane diol
- An alternative is to wear long-sleeved shirts and pants – although that’s tough in our hot weather
- Wear clothing that is pre-treated with permethrin or apply a permethrin product to your clothes, but not your skin!
- Avoid getting bitten while you sleep by choosing a place with air conditioning or screens on windows and doors or sleep under a mosquito bed net.
Now let’s talk about mosquito control in your own landscape.
Let’s first explore what kind of environment in your landscape and around your home is friendly to the proliferation of mosquitoes. Adult mosquitoes lay their eggs on or very near water that is still or stagnant. That is because the larvae live in the water but have to come to the surface regularly to breeze. The small delicate larvae need the water surface to be still in order to surface and breathe. Water that is continually moving or flowing inhibits mosquito populations.
Look around your home and landscape for these possible sites of still water that can be excellent mosquito breeding grounds:
- bird baths
- potted plant saucers
- pet dishes
- old tires
- roof gutters
- tarps over boats or recreational vehicles
- rain barrels (screen mesh over the opening will prevent females from laying their eggs)
- bromeliads (they hold water in their central cup or leaf axils)
- any other structure that will hold even a small amount of water (I even had them on a heating mat in a greenhouse that had very shallow puddles of water!)
You may want to rid yourself of some of these sources of standing water or empty them every three to four days. What if you have bromeliads, a pond or some other standing water and you want to keep them and yet control mosquitoes? There is an environmentally responsible solution. Some bacteria, Bacillus thuringiensis ssp. israelensis or Bacillus sphaericus, only infects mosquitoes and other close relatives like gnats and blackflies and is harmless to all other organisms. Look for products on the market that contain this bacteria.
