According to Druid lore, hanging the plant in homes would bring good luck and protection. Holly was considered sacred because it remained green and strong with brightly colored red berries no matter how harsh the winter. Most other plants would wilt and die.
Later, Christians adopted the holly tradition from Druid practices and developed symbolism to reflect Christian beliefs. Today, the red berries are said to represent the blood that Jesus shed on the cross when he was crucified. Additionally, the pointed leaves of the holly symbolize the crown of thorns Jesus wore on his head.
Several hollies are native to Florida. Many more are cultivated varieties commonly used as landscape plants. Hollies (Ilex spp.) are generally low maintenance plants that come in a diversity of sizes, forms and textures, ranging from large trees to dwarf shrubs.
The berries provide a valuable winter food source for migratory birds. However, the berries only form on female plants. Hollies are dioecious plants, meaning male and female flowers are located on separate plants. Both male and female hollies produce small white blooms in the spring. Bees are the primary pollinators, carrying pollen from the male hollies 1.5 to 2 miles, so it is not necessary to have a male plant in the same landscape.

Several male hollies are grown for their compact formal shape and interesting new foliage color. Dwarf Yaupon Hollies (Ilex vomitoria ‘Shillings’ and ‘Bordeaux’) form symmetrical spheres without extensive pruning. ‘Bordeaux’ Yaupon has maroon-colored new growth. Neither cultivar has berries.
Hollies prefer to grow in partial shade but will do well in full sun if provided adequate irrigation. Most species prefer well-drained, slightly acidic soils. However, Dahoon holly (Ilex cassine) and Gallberry (Ilex glabra) naturally occurs in wetland areas and can be planted on wetter sites.
Evergreen trees retain leaves throughout the year and provide wind protection. The choice of one type of holly or another will largely depend on prevailing environmental conditions and windbreak purposes. If, for example, winds associated with storms or natural climatic variability occur in winter, then a larger leaved plant might be required. Several cultivars have been created by cross pollination with native species or propagation from sports of natives. Check out ‘East Palatka’, ‘Savannah’, ‘Nellie Stevens’, ‘Robin’, and ‘Screen Play’.

The natives are likely to be better adapted to local climate, soil, pest and disease conditions and over a broader range of conditions. Nevertheless, cultivars may be desirable for many attributes such as height, growth rate and texture but should not reproduce and spread beyond the area planted. When introducing a new plant to the landscape it is always important to consider any negative impacts.
There is increasing awareness of invasiveness, i.e., the potential for an introduced species to establish itself or become “established” in an ecological community and even become a dominant plant that replaces native species. Tree and shrub species can become invasive if they aggressively proliferate beyond the windbreak. At first glance, Brazilian pepper (Schinus terebinthifolius), a fast-growing, non-native shrub that has a dense crown, might be considered an appropriate red berry producing species. However, it readily spreads by seed disbursed by birds and has invaded many natural ecosystems. Therefore, the Florida Department of Environmental Protection has declared it illegal to plant this tree in Florida without a special permit. Consult the Florida Invasive Species Council (FISP) https://www.floridainvasives.org/ for a list of prohibited species in Florida.

Diospyros virginiana, the Common Persimmon, is a large deciduous tree in the Ebenaceae family. The common persimmon is a southern native small to medium fruit tree that is becoming more popular for homegrown fruit. The bark is grey or black and forms chunks or blocks that give it a checkerboard look. Fall color can be a spectacular red in USDA hardiness zones 4 through 8a. It is well adapted to cities but requires fallen fruit maintenance and wildlife control. Its mature height can be 40 to 60 feet, with branches spreading from 20 to 35 feet and a trunk two feet thick, but it is commonly much shorter in landscapes. The trunk can have a singular or multiple trunks, it tends to form colonies. The leaves are alternate, simple, and a rich green color. The leaf margins can be entire or somewhat serrated. The funnel-shaped flower has four petals and ranges in color from white to cream to gray.

The common persimmon is smaller than a ping-pong ball. The persimmon is a round fruit with an orange to reddish-purple color, with a size of 1 ¼ inches across. The flavor is more fermented and sugary-sweet. In Florida, the season is from late August to early November. Fruit do not ripen at the same time. When ripe, the fruit turns from green to burnt orange. They also fall from the tree. The fruit is soft, sticky, and very delicious, but it needs to be separated from its skin and seeds before being used in recipes. They can be eaten out of hand when fully ripe, pureed, dried, and used in preserves, chutneys, quick breads, puddings, pies, and sweet and savory dishes. The fruit is very favored by wildlife. Persimmon fruit is an essential food source for songbirds, turkeys, and small and large mammals.

Common persimmon prefers moist, well-drained, bottomland or sandy soils but is known to be very drought- and urban-tolerant. It is a fantastic tree in its adaptability to site conditions, including alkaline soil. It is commonly seen as a volunteer tree in old fields but grows slowly on dry sites. Its fruit is an edible berry that usually ripens after frost. Some cultivars do not require the frost treatment to ripen. Persimmon fruit is hard and astringent when unripe. Most American cultivars require both male and female trees for proper fruiting.
Besides fallen fruit maintenance, persimmon maintenance is easy and is suggested that it persimmon should be planted more often. Due to a coarsely branched root system, transplantation is difficult. The trees should be balled and burlapped when young or grown from containers. The wood from the tree is used for golf club heads because it is tough and almost black.
Common persimmon is troubled by a leaf-spot disease in the south. This disease causes black spots on the leaves and premature defoliation in August in the north and September in the south. The tree will not die from the disease. It is also susceptible to a vascular wilt, which can devastate established trees. There are no severe pests fort his native fruit tree, except occasional caterpillars.

What do ice cream, make-up, paint, plastic, air freshener, laundry detergent, cellophane, and rayon fabric have in common? They all have pine tree in them. There are hundreds of products that contain the cellulose or sap from the pine tree species native to Florida’s panhandle, particularly Longleaf and Slash pines.
Early foresters of the 1800’s discovered these pine species that grew tall and strong. In fact, Longleaf pines were so overharvested that there is only about 3% of the original forests remaining today. These trees not only provided a huge resource for lumber, they also supplied the fluids necessary to support the timber industry – turpentine. By “cat-facing” (cutting downward angled slashes) the trunk of pine trees, the sap would flow into collection cups placed on the trunks. It was collected and heated.
Pine tree sap- turpentine
Turpentine is a fluid obtained by the distillation of resin harvested from pine trees. As a solvent, it is used for thinning oil-based paint, for producing varnishes, and as a raw material for the chemical industry. Add some beeswax and it becomes furniture wax. In the early years, turpentine mixed with coal oil and kerosene was used as a topical wound dressing and lice treatment. Add some animal fats to make primitive vapor rub.
Terpene is the scientific term coined in 1866 to denote all hydrocarbons with the formula C10H16. The word was a shortened form of “terpentine”, the obsolete spelling of “turpentine”. Terpenes are major biosynthetic building blocks for the oils in plants. For the plants, these oils play a critical role in defense against herbivory, build disease resistance, and aid in attracting pollinators. When the resin of pine trees (turpentine) is distilled, each of the terpenes can be separated. Based on there formulation, the terpenes are the base for fragrances and flavoring in numerous consumer products. With various heating treatments, many “fresh scented” cleaning products and antiseptics can be produced. Others terpenes will add “taste” to ice cream, chewing gum, and even beer. The cellulose separated from the turpentine is used to provide “structure” to cosmetics, fabrics, impact-resistant plastics, and modern digital display screens.
Who knew that you could get so many uses from pine trees. They are not just for making 2 x 4s anymore. In fact, the 1939 Nobel Prize in Chemistry was awarded to the scientist that sorted out the 55,000 terpene compounds from turpentine. You may never look at a pine tree (or your beer) the same way again.
As the name implies, they are haunting—long stretches of standing, dead trees with exposed roots. These “ghost forests” are an unsettling scene in unsettling times for the environment. While coastal erosion is a fact of life—incoming waves, hurricanes, longshore drift of beach sand—the rate of its occurrence is startling lately.

Global rises in sea level due to increased atmospheric carbon levels mean more saltwater is moving into flat, coastal habitats that once served as a buffer from the open water. Salt is an exceedingly difficult compound for plants to handle, and only a few species have evolved mechanisms for tolerating it. Low-growing salt marshes and thick mangrove stands have always served as “first line of defense” buffers to take in wave action and absorb saltwater. If shorelines have too much wave action for marshes to form, wide stretches of sandy beach and dunes serve the same function, protecting the inland species of shrubs and trees. Many coastal areas are flat and stay at or just above sea level for thousands of yards, or even miles. This means that even a small increase in sea level can send saltwater deep into previously freshwater systems, drowning the marsh and flooding stands of oak and pine. The salt and sulfate in seawater will kill a tree quickly, although it may remain standing, dead, for months or years. Hurricanes and tropical storms exacerbate that damage, scouring out chunks of shoreline and knocking down already-unstable trees.
A slow increase in sea level could be tolerated and adapted to as salt marshes move inland and replace non-salt tolerant species. But this process of ecological succession can be interrupted if erosion and increased water levels occur too quickly. And if there is hard infrastructure inland of the marshes (like roads or buildings), the system experiences “coastal squeeze,” winnowing the marsh to a thin, eventually nonexistent ribbon, with no natural protection for that expensive infrastructure.

Ghost forests are popping up everywhere. Last year, Popular Mechanics magazine reported on a recently published study that used satellite imagery to document how 11% of a previously healthy forest was converted to standing dead trees along the coast of North Carolina. The trees died within a span of just 35 years (1984-2019). During that time frame, this stretch of coastline also experienced an extended drought and Category 3 Hurricane Irene. These impacts sped up the habitat loss, with over 19,000 hectares converted from forest to marsh and 1100 hectares of marsh vegetation gone, becoming open water.

Due to increased coastal flooding and saltwater standing in forested areas, U.S. Fish and Wildlife Service employees are concerned that the historic Harriett Tubman Byway in Maryland—part of the famed underground railroad of the Civil War era—will soon be gone. Over 5,000 acres of tidal marsh have converted to open water in the area and large stands of trees have died. Even locally, trees along Escambia and Blackwater Bay are dying due to salt damage and heavy erosion. Hurricane Sally delivered a knockout punch to many remaining trees along the scenic bluffs of the bay.
Sea level has risen over 10” in the past 100 years in the Pensacola Bay area, and even mid-range Army Corps of Engineers estimates expect 0.6 to 1.4 feet of rise in the area by 2045. There are some actions we can take to mitigate future damage. Building a “living shoreline” of vegetation along a piece of waterfront property instead of using a seawall can help, especially if the vegetation growth outpaces sea level rise. You can also visit the City of Pensacola’s Climate Task Force report to learn more about climate action recommended (and being taken) locally, such as increasing the use of renewable energy and dedicating staff to sustainability measures.

I get calls every year about planting pines, stand establishment, and related requests. I also get many calls from landowners who have planted pines recently (10 years or less) and are wondering what to do going forward. Ideally, they are from landowners that have well thought out plans and just need some assistance with the finer details or are experiencing some unexpected issues. Unfortunately, I do often get calls from landowners that are just at a loss and are planting or managing with no real plan for now or the future. These landowners have great goals and intentions, but they are new to forest ownership and the long-term nature of forest management comes as a bit of a surprise. I love helping these landowners out though because often I can catch them early and get them on the right track. Establishing a forest stand right from the beginning and managing it well in the early establishment phase is critical to success. Mistakes can often stick around and be felt a decade or more in forestry; it is just part of forest ownership and management.
In over a decade of forest management practice I cannot stress to landowners and forestry professionals the critical importance of getting initial planting and establishment right. This is not the time to have a vague plan or to cut costs or corners. What you do now may well haunt you and impact your goals and investment return for over 30 years. In row crop agriculture you can often make corrections year to year, but in forestry missing competition control or a thinning can impact growth for the entire rotation. Considering that on average a landowner will get to see two rotations of timber in their lifetime, the margin for mistakes and missed opportunities is very slim. This is why it is so important when establishing a forest or reforesting after a final harvest that the planting plan and early management plan be well thought out and executed.
Winter is forestry planting season, and it is in full swing right now. Peak planting is usually in the months of December and January, but forest planting usually runs from November to the end of February or first of March. This is the opposite of most other agricultural and plant establishment operations because trees are best planted while they are dormant. Winter is the best time because when trees are dormant, they focus energy on root growth, and thus a newly planted seedling will focus on establishing it’s root system and be ready to start growing in spring. You may be wondering about pines and evergreens since they keep their foliage, but this is true for them as well. Pines have a dormant period in winter that is induced by weather and the amount of low temperature chill hours. They do not lose their needles but continue to photosynthesize. They do not actively grow new foliage or start renewed growth until spring. This is why winter is the best time to plant both forest and urban trees of all types and why Florida celebrates Arbor Day on January 20th (check your local county information for your local celebrations).
If you are conducting reforestation operations this winter, as many are, now is a great time to update your forest management/stewardship plan. If you are planning to plant trees or reforest in the near future, or if you are planning to harvest timber soon, now is a great time to work on a reforestation and stand establishment plan. If you are not working with a consulting forester it is highly encouraged you work with one to help with your reforestation, planting, and forest management needs. These highly trained professionals are equipped to help you make the best forest management decisions and can assist with locating contractors and forestry service providers. Using a consulting forester makes reforestation and management much easier for a landowner and results in better outcomes. Use of a consultant is not required though, so if you are a do-it-yourself landowner you will want to make sure all your ducks are in a row well before planting time comes around. The key to that is a good planting and stand establishment plan. UF IFAS has a great new EDIS publication out and available for landowners on planting southern pines in Florida. You can access the article here FOR385/FR456: Planting Southern Pines in Florida (ufl.edu) . For those who aren’t aware; recovering forests in the Hurricane Michael impact zone has become one of the largest reforestation and recover projects in the state’s history. If we get those reforestation efforts right now; it will pay big dividends for our landowners and communities in the future. The same goes for normal year to year reforestation efforts across the state as well.
A good reforestation or tree planting plan has several components. The core components are: type of regeneration natural vs. artificial, site and stand preparation, seedling establishment/planting, survival and early stand assessment, and early management of vegetation and fertility. For this article we will focus on artificial regeneration, which is when nursery grown seedlings are planted on the site. This is by far the most prevalent method, and it provides the most control over density and seedling quality. This also allows the use of genetically improved seed stock, which can greatly enhance forest productivity and value at end of rotation. Most pine planted in the southern United States now uses genetically improved seed stock. This is the result of decades of careful selection, testing, and deployment; much like agricultural crops like corn, cotton, etc. A landowner planting trees today has access to some of the best site preparation and reforestation seedling stock ever available, and taking advantage of it pays huge dividends. Here are the steps you can take as a landowner to get your plan outlined.
Determine the timeline for reforestation and plan accordingly.
Determine the species, density, seed source, genetic improvement level, and nursery availability of your desired seedlings.
Determine the site preparation required to ensure planting success
Determine the planting method; reserve planting labor and seedlings required to accomplish planting
Have planting contractor and nursery logistics coordinated for day of planting
Establish a follow up survival assessment period and have a plan to correct a full or partial planting failure.
Follow up on monitoring your stand and have plans for control of competing vegetation and other early stand treatments.
The work does not stop once you have the trees planted and the young stand is established. One of the biggest mistakes made in forest management is a “Plant Them and Forget Them” approach to timber management. This is a near guarantee to have issues especially in Florida with its fast vegetative growth, heavy competing vegetation, and propensity to hurricanes and wildfires.
Once you have your stand established by executing your reforestation plan; you want to move into forest management and stewardship for the long haul. This means you will need a Forest Management or Forest Stewardship plan to get a handle on what your young forest needs going forward. The plan is usually written to cover a 5-to-10-year period and then it is reassessed and revised.
A landowner with 20 acres or more can enroll in the Forest Stewardship Program through the Florida Forest Service and receive a Forest Stewardship Plan written by the county forester or a consultant. Forest Landowners with 160 acres or more are encouraged to use a private consultant to develop a plan. Landowners that use a consultant can receive funding through the program to help cover the cost of the plan. For more details and to enroll in the Forest Stewardship Program contact your county forester and follow this link Forest Stewardship Program / Programs for Landowners / For Landowners / Forest & Wildfire / Home – Florida Department of Agriculture & Consumer Services (fdacs.gov) . Once you have your plan and complete the program you get a great Stewardship Forest sign to advertise your commitment to being a good land steward.

The old adage “Fail to plan, Plan to fail” unfortunately often holds true for reforestation and forest management. Failed planting operations and missed opportunities can cost a landowner significantly. To ensure the success of your reforestation efforts and early timber management; get a plan and have one for the long haul. When planned out well, tree planting operations usually go smoothly and are successful. Followed up with a good forest management plan this covers the critical early establishment period and will ensure a successful forest management operation. Getting a plan together is a minimal cost compared to a failed planting or reduced growth and yield. Using a private consulting forester of your choice and working together with a forestry professional can get you off to the long-range project that is timber management. If you are planning on planting trees now or in the future; plan well and follow up. Years from now you will enjoy seeing your goals and objectives come together.
The colder part of the year is the best time to install hardy trees and shrubs. All their energy is in the root zone. They will establish much faster than if you wait until they are actively growing leaves.

However, planting them correctly is critical to their survival. The top three mistakes that people make are: (1) installing too deeply, (2) leaving the rootball undisturbed, and (3) not applying enough water all the way through establishment of the root system. Unfortunately, it may be years before the mistakes are noticed.
Here are the ten steps for successful planting:
1. Call 811 and have all underground utilities marked before digging the hole.
Hitting a line can be costly and life threatening.
2. Loosen all surrounding compacted soil within the potential root zone of the tree.
Tree roots are close to the surface and need to be able to push through the soil.
3. If the soil is extremely dry and sandy, amend with the entire area with organic material.
This is only needed in coastal regions.
4. Remove the container from the tree and find the top-most root.
All media covering the root flare must be removed.
5. Prepare the rootball by removing encircling roots and shaving the edges of the rootball.
The rootball should no longer be shaped like the container when complete.
6. Dig the hole slightly less shallow than the rootball.
Make sure the bottom of the hole is firm soil, so sinking will not occur.
7. Place the rootball in the ground with the main root showing just above the soil grade.
Oxygen must reach the roots for new roots to develop.
8. Back fill around the rootball with the surrounding loose soil.
Take care to not cover the root flare.
9. Mulch around the outside of the rootball without covering the rootball.
Apply at least 2-3 inches of organic mulch. No more than 4″.
10. Water immediately to settle soil and then on a regular schedule until established.
Minimum of 1 gal per 3 gal plant, every 2-4 days, for 20-28 weeks. Larger plants will require more water at each event.
Mulch should be spread about 3 inches thick around the rootball. No mulch should be spread over the rootball.
