There’s plenty of animals you might call “cute”, but lizards usually aren’t among them. However, I’d take exception to that premise when discussing the green anole (Anolis carolinensis). With big blue eyes, brilliant green skin, and flirty males doing push-ups and flexing their dewlaps (the pink throat fan) at you, these little reptiles are more endearing than most.

Native to Florida and the deep South, they are competent crawlers, prowlers, and predators. I see them frequently on my office building’s outer stucco walls, running along fences, or skittering up trees. They feed on beetles, termites, ants, worms, spiders, and more. Called the “American chameleon” by some, they possess excellent camouflage, changing their skin rapidly from green to dull brown depending on their backgrounds.
Over the last few years, I—and many biologists—have been concerned about the health of their population. As the invasive Cuban brown anole successfully gained a foothold in north Florida, I saw fewer green anoles and many more of the browns. It has seemed that the greens were losing ground. The invasive species can outcompete the native by eating the green anoles’ young and eggs.

A recent study by a UF PhD candidate found another explanation for why Floridians have seen more brown anoles than green. His study found that the two species have found a way to coexist—the green anoles are moving further up the canopy (an average of 17x higher!), while browns are staying closer to ground level. The green anoles thrive in more natural areas, whereas the brown anoles do well in lower level urban surroundings.
Interestingly, this summer I’ve noticed a resurgence in green anoles and have rarely seen brown ones. I am wondering if our snow days knocked the tropical brown anole populations back, enabling the more temperate greens to recover. Time will tell if the greens have regained their advantage or if it’s only temporary.
Normally, when one thinks of flowers that can take Florida’s summer heat, Petunia isn’t the first species that comes to mind, certainly not for me. For our northern neighbors, Petunias are one of the most popular summer bedding plants; their warm days and cool summer nights are perfect for Petunias. But, in the deep south, we are forced to grow Petunias in the cool months before the summer heat melts them. However, with the introduction of Wave Petunias back in 1995, the idea of a heat tolerant hybrid Petunia that could extend flowering was born. Then a decade later in 2006, Proven Winners debuted the next evolution of heat tolerant Petunias came along, the ultra-tough Supertunia Series, and disrupted everything we thought we knew about growing Petunias.

There are several sub-series of Supertunia, all are good in my experience, but my favorite and the most resilient to heat is definitely the Vista® series, specifically the cultivar Vista® Bubblegum®. Vista® Bubblegum® is a massively growing Petunia that can spread in excess of 4’ and possesses vivid pink flowers with dark pink veins. Adding to the appeal of Vista Bubblegum is its self-cleaning nature, meaning no deadheading is required and it will flower more or less continuously throughout the life of the plant. However, the most outstanding aspect of the plant is its heat tolerance (for a Petunia). In general, Petunias in the Panhandle are planted in the fall, grow through the *usually* mild winter months, flower in the spring and then begin to languish in the heat of May-June. Vista® Bubblegum® chooses instead to laugh at the heat and mine (planted in early November) are still going strong, unfazed by the heat, in the second week of a very hot July. This plant just won’t quit. Pretty impressive stuff.

For best results with Vista® Bubblegum® and all other petunias, be sure to site in a location with full sun and keep regularly watered and fertilized, especially if grown in containers, as these prolific bloomers require a lot of energy to support the months-long flower show. Unfortunately, unless you already have Vista® Bubblegum® in your garden, you’ll have to wait until the fall to find more in nurseries, but these plants and its series siblings are well worth the wait! Plant a few this fall and enjoy beautiful color throughout next spring and summer.

The Panhandle has experienced a significant amount of rain lately. It seems like there isn’t a day that goes by in which even walking out the door seems impossible due to the downpour. While this is hard enough for the people living in the area, without a mitigation strategy, your lawn and landscapes may be suffering just as much. The good news is that there are several methodologies to usher the excess into local surface water reservoirs.
The Issue
Before we get started, let’s first talk about why storm water needs to be managed. Storm water can be defined as any rainfall failing to infiltrate the soil. In short, it is water that flows from your property onto impervious ground into storm water drains and ultimately into the Gulf of America.
This water can and will carry pollution from houses, pet waste, and heavy metals, amongst other things, into our local waters. All of that is before we even account for nitrogen moving from the atmosphere during these storms. All of this may be detrimental to local aquatic populations, ultimately leading to eutrophication due to excess nutrients. In the worst cases, these nutrient-rich waters cause red tide, which limits recreational use and fishing in our area.
The good news is that homeowners can take specific actions to mitigate the risks associated with storm water. The three primary types of these are rain gardens, swales, and rain barrel catchment systems.
Rain Gardens
A rain garden is an area planted with vegetation designed to prevent mass water flow on your property. They may be sited in multiple locations, including sloped yard areas, or those in which you notice pooling following a rain event.
Carve out the area and backfill with porous soil materials. The plants you’ll want to select for this garden should be able to tolerate drought followed by periods of flooding. One solid strategy for this mitigation system is to direct the downspouts from your house into one of these garden spaces. Between the turfgrasses planted along the water’s path and the root systems of the plants within the rain garden, storm water will be pushed through a biofiltration system while being redirected from the local watershed. To learn more about rain gardens, consult these document.

Swales
Swales are like rain gardens in that their primary purpose is to redirect water flow. While these may be outfitted with vegetative plantings termed bioswales, the highway for water flow in traditional swales typically consists of turfgrasses.
These are quickly draining soils, aided further by the thick root masses inherent to grass. Where they differ from rain gardens is in the amount of work they require. Critical to this system is selecting turfgrass species suitable for the site and applying the correct water, fertilizer, and mowing practices. These practices allow for strong and stress-free grass growth.
Rain Barrels
Last, though certainly not least, are rain barrels. These may be found at the downspout of gutter systems attached to houses. Their purpose is to collect the stormwater flowing from the roof. They can be a handy tool in eliminating stormwater runoff. To learn more about designing rain barrel catchment, consult this document.

Stormwater is a significant concern in our lawns and landscapes. If allowed to go unchecked, it provides an avenue for pollutants and excessive nutrients to enter our waterways. Implementing the strategies in this article can significantly reduce these risks. For more information on stormwater management or any horticulture topic, refer to your local Extension office.

The Panhandle’s dreaded summer heat has finally arrived in force and has brought with it one of the most difficult to control lawn/landscape weeds, our annual enemy Doveweed (Murdannia nudiflora). Doveweed is characterized as one of the world’s worst weeds due to its broad range of growing conditions, ability to root along its stems, forming mats as it grows, massive seed production (each plant can produce up to 2,000 seeds per year), and inconspicuous nature – it looks like a grass to the untrained eye. So, what can gardeners do to control Doveweed that’s already up this year and prevent it next summer? Let’s find out.

First, the best prevention for all weeds, Doveweed included, is a healthy lawn/landscape. Ensuring healthy, thick Centipedegrass turf and landscaped beds that don’t allow light to hit bare soil goes a long way towards reducing the overall weed load lawns and landscapes can experience. For lawns, this can be achieved through mowing regularly at the proper height for your turfgrass (2.5” or so for Centipedegrass), irrigating no more than 0.75”-1” per week in the absence of rain, limiting stress from overfertilization, and removing excess thatch. In landscapes, preventative weed control focuses on limiting overwatering/fertilization and maintaining a 2-3” organic mulch layer of pinestraw, pine bark, leaves, wood chips, etc. Adopting these practices can greatly reduce the occurrence of weeds in your yard, however they will not eliminate weeds altogether and supplemental chemical weed control is often necessary.
Unlike Crabgrass, Florida Pusley, and other commonly encountered Panhandle annual weeds that emerge when the soil begins to warm in early spring (usually late February-March), Doveweed waits until mid-April-May (soil temperatures of 70-80 degrees F). All these annual weeds are best controlled by preemergent herbicides, like Indaziflam (Specticle G), before seeds germinate. For Doveweed, that means the first preemergent application should occur mid-April with a follow-up application 6-8 weeks later. However, for this year that opportunity is behind us and our only option is post emergent herbicides.
Which postemergent herbicide you choose depends on if your Doveweed issue is in turfgrass or in landscaped beds. In landscaped beds, the primary control option is either hand pulling or spot treating Doveweed with a 41% glyphosate product (Roundup and other generic products) at a rate of 3% (3-4oz glyphosate/gal). As glyphosate is a non-selective herbicide, be sure to not get any overspray on any ornamental plant foliage. In turfgrass, Doveweed control becomes a little more difficult. You essentially have three options – atrazine, a generic 3-way broadleaf product, or a commercial grade broadleaf product. Though it provides very good control of Doveweed and has pre-emergent properties to help discourage future weeds, I don’t prefer atrazine because it has a high potential to leach into groundwater following heavy rains in sandy soils, which describes much of the Panhandle. The generic 3-way products (usually a mix of Dicamba, Mecoprop, and 2,4-D) are fairly effective on Doveweed, however follow-up applications are usually required and the 2-4D component can be harsh on Centipedegrass at the higher label rates required for Doveweed control. Though somewhat expensive, the best post emergent option for most people is probably a commercial grade product like Celsius WG. Celsius WG is a very strong post emergent broadleaf herbicide that is very effective on Doveweed and is also very safe on Centipedegrass, even in hot weather. If the cost of the product (>$100) is off-putting, it is helpful to remember that even at the highest labelled rate, a 10 oz Celsius WG bottle goes a long way, enough to cover several acres of lawn.
* Regardless of what method you choose, be sure to get after emerged Doveweed seedlings early, before they mature and begin flowering – even the strongest post emergent herbicides work better on young weeds.
While Doveweed is a nasty little plant that is perfectly capable of taking over a lawn or landscaped bed, there are a variety of preventative and control options available. Using a combination of the above techniques should help achieve lasting Doveweed controls in future seasons!

Lawns are as American as apple pie, and Granny’s cookies. It’s where you play ball with your kids, and have summer cookouts. It’s also quite likely a huge source of frustration. How much water, how much fertilizer, how much work, and why bother? All of these are valid questions, and ones this article seeks to clarify. We’ll delve into the benefits of healthy lawns, and cover some easy cultural practices you can implement right now for a green and lush lawn all summer long.
The Benefits of Lawns
Turfgrass provides a number of ecological services. These are defined by the USDA as “direct and indirect benefits provided to humans by an ecosystem to include provisioning, regulating, supporting and cultural services”. This term has multiple categories, which are outlined below.
Provisioning (AKA Material and Energy Output)
Provisioning or material/energy output is linked to a grass’ bio-filtering capability. Grasses remove pollutants from applied water including stormwater, while enabling ground infiltration. This recharges surface reservoirs, and by removing pollutants, mitigates eutrophication while providing clean drinking water to communities.

Regulating (AKA Moderation and Control of Ecosystem Processes)
Grasses are known to cool the surrounding environment, capture dust, and prevent erosion.
Water absorbs heat as it vaporizes as it does in the evapotranspiration processes in plants. As Ben Franklin taught us many years ago, that process cools the environment around through heat absorption as water vaporizes. This cooling effect can be quite significant, and translates to saving through reduced air conditioning of your home.
Grasses remove dust and pollen particles from the air as well. This is usually a process by which wind blows the dust onto the grass, the dust settles and is captured beneath the grass canopy.
To complete the trifecta, grass has a thick root mass locking soil in place. The two main methods for soil erosion are through wind, and water flow. The grass’ root system negates both of these.
Supporting Services (AKA Maintaining Fundamental Ecosystem Processes)
Supporting services, as this sections title suggests, are those which support life processes. In the case of grasses, this comes in the form of organic matter. As I hear often, soils in Florida are quite sandy and lacking in the aforementioned organic matter.
It may surprise you to hear that grass is probably the easiest method to make these additions. As we leave clippings on the lawn and root systems slough off only to regrow the following spring we actually are adding organic matter from two directions. Hence grass’ reputation as a great soil builder.
This organic matter is where our supporting services really shine. Your turfgrass acts as habitat for microbiota, and macrobiota. These terms refer to the bacteria, fungi, algae, earthworms, and other insects which help cycle soil nutrients while breaking down the same organic matter you’ve added simply by not removing your grass clippings.
Cultural Services (AKA Societal Benefits)
These are somewhat self explanatory. It is in this realm where we begin to discuss those neighborhood block parties. Lawns are an excellent place to meet with neighbors and build communities. Well maintained lawns can also affect home prices, improve neighborhood aesthetics, and even effect crime rates in a given area.

It Starts with Cultural Practices
Hopefully by now, you are sold on keeping a healthy stress free lawn. The real question is how to achieve one? You’ve likely heard that lawns are difficult to maintain, but you’ll be happy to know it’s much easier than advertised. You’ll see rapid results if you start paying attention to three practices.
Irrigation
Easily the biggest killer of grasses in North Florida is irrigation. Often too much is applied, and is at the wrong time of day. All turfgrass species in Florida require only ½ -3/4 inch of water per irrigation event. Water your grass before dawn when you notice bent grass blades, slight color changes, and a lack of rebound when stepped upon.
Not sure how much you’re applying? Place some containers in your watering zone spread evenly and run the system for 15 minutes. Measure that outcome with a ruler, adjust your timing as necessary to hit the right amount.
Fertilization
Fertilization is based on turfgrass species. Overdoing things can be quite harmful to your lawn, so make sure you check the Florida Lawn Handbook for the specifics on your grass species.
Before you get started fertilizing, there are a few bits of information of which you should be aware. The first is your soil’s pH, as it dictates nutrient availability for your grass. The second factor in fertilization is timing. Apply fertilizer in multiple applications beginning April 15th and ending in September. This ensures your grass will have enough root mass to utilize the nutrients.
Mowing
Our final cultural practice is mowing. It is critical to mow plant to the appropriate height. Mowing to proper height keeps grass stress free reducing susceptibility to insects, disease, drought or sunscald. Here again, height is dependent on grass species. Consult the Florida Lawn Handbook for greater detail.
Whatever the height required. Make sure to mow grass with sharp blades, only when dry, and weekly to avoid damage to your plants.
To Sum it All Up
Turfgrasses are an integral part of any landscape when sited correctly. They provide a wealth of functions both ecological and cultural. Take a little time to integrate the practices outlined above and you’ll discover an easy to maintain groundcover primed for your next family cookout. As always, if you have any questions or need any help on this topic and more, contact your local Extension Office.
