Working in Extension has given me a lot of interesting opportunities. On the job, I’ve found myself leading kayak trips all over Florida, building a two-story bat house, and wearing a Mr. Peanut costume while talking about agriculture. But I never really imagined being featured on a home improvement reality TV show. Sure, I’ve watched my fair share of Extreme Makeover: Home Edition and Love it or List it, but those were just entertaining ways to pass the time and maybe get some ideas for my own house.
Then, a few months ago our office was contacted by the producers of a show called Flip My Florida Yard, to inform us they would be in Escambia County to film an episode of the show for the Discover Florida channel. As part of the effort, they’d need a local Extension agent to go on a site visit, help review the landscape design, and talk about Florida friendly landscaping principles on air. Based on my prior experience as a Florida Yards & Neighborhoods agent (and our horticulture agent being swamped with Master Gardener training), I got the reality TV job.

Part education and part entertainment, the show’s premise is similar to most home remodeling shows. A couple or family wishing to improve their current home shares their hopes with the remodelers, the homeowners are sent away for a day, and upon their return they are surprised with a brand-new look.
The twist with Flip My Florida Yard is that the landscapes in need of improvement are redesigned with Florida-friendly principles in mind. During each episode, Extension agents, IFAS researchers, and landscape designers are interviewed about concepts like using mulch and compost, proper irrigation, or “right plant, right place” choices based on soil type and sunlight availability. Last season, the crew was in Panama City to help a family restore their yard after damage from Hurricane Michael. For our Escambia County program, we will focus on appropriate fertilization, managing stormwater, protecting the waterfront, and providing wildlife habitat.
The “Flip My Florida Yard” program features Florida homeowners getting a Florida-friendly landscape renovation. The show is available online and through several streaming services.
In late December I was interviewed by the show’s producers, and we spent a full day renovating a local backyard. The challenging, steeply sloping backyard was given some really nice amenities, including a rain barrel, a seating area, and wildlife attractants. Our local episode should air in March or April. In the meantime, all the past episodes are available for viewing on the Discover Florida Channel. The channel can be accessed via a free online account, or through several streaming services like Roku, Apple TV, and Amazon Fire. Flip My Florida Yard is a creative partnership between the Department of Environmental Protection/Florida State Parks and the state level UF IFAS Extension Florida Friendly Landscaping Program, so even the commercial breaks cover environmentally friendly messages and scenic views of state parks. Check it out—you might get some helpful ideas or even become the next homeowner featured!

The best time to plant a tree is twenty years ago. The second-best time is Arbor Day. Florida recognizes the event on the third Friday in January but planting any time before spring will establish a tree quickly.
Arbor Day is an annual observance that celebrates the role of trees in our lives and promotes tree planting and care. As a formal holiday, it was first observed on April 10, 1872, in the state of Nebraska. Today, every state and many countries join in the recognition of trees impact on people and the environment.
Trees are the longest living organisms on the planet and one of the earth’s greatest natural resources. They keep our air supply clean, reduce noise pollution, improve water quality, help prevent erosion, provide food and building materials, create shade, and help make our landscapes look beautiful. A single tree produces approximately 260 pounds of oxygen per year. That means two mature trees can supply enough oxygen annually to support a family of four.
The idea for Arbor Day in the U.S. began with Julius Sterling Morton. In 1854 he moved from Detroit to the area that is now the state of Nebraska. J. Sterling Morton was a journalist and nature lover who noticed that there were virtually no trees in Nebraska. He wrote and spoke about environmental stewardship and encouraged everyone to plant trees. Morton emphasized that trees were needed to act as windbreaks, to stabilize the soil, to provide shade, as well as fuel and building materials for the early pioneers to prosper in the developing state.
In 1872, The State Board of Agriculture accepted a resolution by J. Sterling Morton “to set aside one day to plant trees, both forest and fruit.” On April 10, 1872, one million trees were planted in Nebraska in honor of the first Arbor Day. Shortly after the 1872 observance, several other states passed legislation to observe Arbor Day. By 1920, 45 states and territories celebrated Arbor Day. Richard Nixon proclaimed the last Friday in April as National Arbor Day during his presidency in 1970.
Today, all 50 states in the U.S. have official Arbor Day, usually at a time of year that has the correct climatological conditions for planting trees. For Florida, the ideal tree planting time is January, so Florida’s Arbor Day is celebrated on the third Friday of the month. Similar events are observed throughout the world. In Israel it is the Tu B Shevat (New Year for Trees). Germany has Tag des Baumes. Japan and Korea celebrate an entire week in April. Even Iceland, one of the treeless countries in the world observes Student’s Afforestation Day.
The trees planted on Arbor Day show a concern for future generations. The simple act of planting a tree represents a belief that the tree will grow and someday provide wood products, wildlife habitat, erosion control, shelter from wind and sun, beauty, and inspiration for ourselves and our children.
“It is well that you should celebrate your Arbor Day thoughtfully, for within your lifetime the nation’s need of trees will become serious. We of an older generation can get along with what we have, though with growing hardship; but in your full manhood and womanhood you will want what nature once so bountifully supplied and man so thoughtlessly destroyed; and because of that want you will reproach us, not for what we have used, but for what we have wasted.”
Christmas is among my favorite holidays. The religious significance, music, lights, amazing food, fellowship with family, and giving and receiving gifts all lend something special to the season. However, the tradition that arguably gets the most attention is selecting and putting up a Christmas tree! Those that participate in the festivities and put up a Christmas tree have three options: purchasing an artificial tree, purchasing a real tree, or growing your own.
While I like the convenience of a pre-lit tree as much as anyone, artificial trees don’t do a whole lot for the environment or sustainable US agriculture. They are almost exclusively produced overseas and contain non-biodegradable plastics. Not the best. If you select option two and choose to purchase a real tree, you’ll help support a sustainable US agriculture industry! According to the National Christmas Tree Association, there are ~25-30 million Christmas trees sold annually in the US and 350 million more currently growing on Christmas tree farms waiting their turn! Purchasing real Christmas trees also ensures that the over 100,000 Christmas tree farm workers remain employed, and the 1/3 million acres US Christmas tree farms comprise will remain non-developed “green spaces”!
But for the green-thumbed Christmas enthusiast that’s willing to put in a little time and effort, there is a third choice – growing your very own Christmas tree right at home! In the Panhandle, there are several species, Florida natives and not, that make wonderful Christmas trees and are easy to grow!
Red Cedar makes a fine Florida Christmas tree!
Red Cedar (Juniperus virginiana) – This Florida native is the classic southern evergreen. Growing quickly to the desired heights of 4’-10’, emitting a “Christmas tree smell”, and possessing dark, dense foliage, Red Cedar makes an excellent Christmas tree! Red Cedar performs very well in most soils but does not like wet feet and will not tolerate continuously saturated areas.
Leyland Cypress (x Cupressocyparis leylandii) – A hybrid of Alaskan Cedar and Monterrey Cypress, Leyland Cypress is recognized as one of the most popular Deep South grown Christmas trees for good reason. Leylands grow exceptionally fast, are a desirable forest green color, and have a naturally conical shape! Though not recommended as long-term landscape trees in Florida due to disease susceptibility, Leylands do very well in short Christmas tree rotations.
Thuja ‘Green Giant’ – ‘Green Giant’ is a cultivar of Thuja and is similar in appearance to Leyland Cypress. Though not quite as deep green in color as Leyland, ‘Green Giant’ also grows rapidly (up to 3’-4’ annually), tolerates many soil conditions, and has no serious insect/disease issues.
Arizona Cypress (Cupressus arizonica var. arizonica) – Arizona Cypress is the Christmas tree for those who would normally choose to be different by purchasing a blue, silver, or white artificial tree! Famous for its striking blue/silver foliage, Arizona Cypress is native to the American Southwest but thrives in the drier sandy soils found in many parts of the Panhandle.
Sand Pine (Pinus clausa) – The quintessential “Cracker Christmas Tree”, Sand Pine is native to the deep sandy ridges of Florida. Normally thought of as a scrubby, low-value tree, when shaped a little, the short-needled Sand Pine makes an excellent Christmas tree! Obviously preferring a dry, sandy site but capable of growing nearly anywhere, Sand Pine has no pest or disease issues and grows fast! If you want a true, old-school Florida Christmas tree, Sand Pine is it.
Regardless of the species you choose, implementing the following few maintenance tips and expectations will lend best results:
Cut/remove J or circling roots before planting.
Plant just higher than ground level.
Refill the hole with native soil from the site.
Regular irrigation for the first several months of their lives is necessary and trees will benefit from supplemental fertilizer applications twice a year (spring and mid-summer).
Shaping trees each summer with hedge shears to achieve the desired dense, compact shape will allow for a uniform tree with no “holes”.
Plant several trees per year to ensure a nice tree come December, just in case.
Florida grown Christmas trees will NOT have the exact look of fir or spruce. Adjust expectations accordingly.
Most Florida grown Christmas trees do NOT have rigid branches and cannot support heavy ornaments. Again, adjust expectations accordingly.
While Christmas tree species that perform well in the Panhandle will not have the exact look of a classic fir or spruce sourced from the Carolinas, they certainly mimic the look and there is something to be said for walking outside and harvesting your own tree to put presents under!

Tree dieback is a complex syndrome and slow developing. Dieback is essentially a process in which trees lose leaves and limbs. This usually occurs as a result of severe stress to the tree’s bark or root system, but could be a result of a declining life cycle.
It’s important to note that there is a significant balance between a tree’s root system and the number of leaves and limbs it can support. For example, if a tree loses part of its root system, possibly due to disease or lawn equipment damage, the tree will forfeit a portion of its leaves. Dieback doesn’t happen overnight, though. It’s a slow process, with larger trees taking much longer time for signs of stress to emerge. However, a large tree root system is very sensitive to damage, whereas a small tree will adapt quickly and is much more resilient to damage. So, what can be done to prevent dieback in trees?
First and foremost, trees, like all living things, have a natural life cycle. Regardless of how you care for your trees, dieback will occur. The most important management measure in extending the life of a tree is to protect the root system and bark.
With each passing year, a tree grows new bark in the rejuvenation process. The bark replacement process inevitably becomes more difficult as the tree gets older and in turn the tree is more and more susceptible to dieback. If the bark becomes damaged, especially later in the tree’s life cycle, then fungi and insects have a much greater chance to cause serious harm. Treating bark damage with a wound dressing to prevent decay is the recommended procedure.

A common misconception is that epiphytes, such as lichens and Spanish moss, are tree diseases. Epiphytes are known as “air plants” and thrive in the Panhandle. They survive on moisture and nutrients in the atmosphere and are harmless to trees. However, a tree that becomes inundated with epiphytes may be an indicator of excessive soil moisture, which may lead to root rot.
Lawn weed killers can have detrimental effects to trees, even if the application seems to be from a safe distance. When using a weed killer near a tree’s root system, confirm on the label that the product is designed to kill green growth only. It can’t be overstated that excessively fertilizing an old tree will greatly accelerate the decline of the tree. Some may think this will stimulate a tree and extend its life, but instead it will do the opposite. Young trees can tolerate fertilizer applications, as they need crown growth. Older trees will simply become top heavy, and structural damage will likely occur.
Don’t forget, trees need space too. A mature tree forced to occupy a small space will simply not adapt. Be sure to have adequate spacing when planting younger trees and shrubs in the vicinity of older trees. Also, keep your trees pruned away from touching structures and utilities.
Tree dieback is a complex issue to manage. By following these measures, you can help extend the life of your trees and continue to have a picturesque landscape.
