It is mid-summer with temperatures outside in the 90’s plus, so you may wonder why article on landscape installation considerations during this time of year. It simply is an excellent time for planning and preparing for fall and winter site prep and planting well before it arrives, reducing a time crunch when it is time to plant.
Think healthy plants for our Northwest Florida settings, proper preparation of the site before planting, and many other points to be successful with establishing a landscape that will be enjoyed by all. This article will address the use of woody ornamental plants, but many things discussed can be applied to perennials and annuals as well.
Before starting, make sure to do your homework not only on the plants and placement in the landscape, but any county, city, or homeowner association requirements to work within. Many neighborhoods have review committees for these approvals. This commitment by you when purchasing property and a home can be a part of the closing papers during the purchase. If you are required to submit for an approval before work can begin you might want to consider consulting with a professional landscape company to assist in this process. Always ask for references and sites you can visit before securing services.
Site preparation can be a afterthought, with limited funding focused on this critical area, but properly addressing it leads to healthy, vigorous plant establishment and future growth. Understanding the site from soil type and drainage, size of area, sunlight, water availability, plus needs of prospective plants goes a long way to being successful. If there are plants already established on site that may be worth keeping, be sure to include them in the consideration. Determining soil drainage, moisture retention that would be available to plants, soil pH and structure will also go a long way to determining the type of plants that work best for the site. If, for example, your site does not drain well and holds higher levels of water in the root zone area (top 12″ of soil), consider plants that grow well in wet settings. The next steps are determining soil pH and nutrient needs for general landscape plant growth performance. Many plants thrive in slightly acidic soil (pH 6.0 to 7.0 range) while others grow best in moderately acidic settings (pH 5.0 to 6.0 range). Contact your local UF IFAS Extension office in your county for additional information.
The landscape site brings other considerations for plants to flourish, involving space and light. Space should be considered both above and below ground. With the above ground area, is there room for the limbs to expand in width and height? If pruning is required to manage the size, considering another plant may be a viable option. Next is the root growth and expansion opportunity for the plant. If the root area is limited in space, other options may need to be considered to mitigate compacted soils or pavement areas. Adding raised beds for better soil drainage and increased root growth room may be an option. Be sure to know your soil type and use a similar soil with characteristic that match the existing soil. If you do not, there can be incompatibility that leads to a hard pan layer between the soils reducing potential root zone establishment.
The desire to develop and establish an enjoyable landscape for all to appreciate can be a challenge, but a positive one. As a reminder, call and go visit with your local UF IFAS Extension office, there is great research information available for the asking. Enjoy your gardening experience.
Since Ponce de Leon first set foot in Florida around Easter in 1513 and gave the state its name – he called it La Florida, which loosely translates to flowery in English – Florida has been known for its amazing native wildflower displays. Florida’s primary native flower shows do indeed occur in the spring (the one observed by Ponce de Leon) and fall, but my favorite Florida “wild” flower is neither a native nor does it bloom in April or October. Rather, the Philippine Lily (Lilium formosanum) does its thing each year in the heat of the summer, when not much else wildflower-wise is blooming.
Hailing from Taiwan and the Philippines but naturalized throughout the Panhandle, the Philippine Lily is easy to spot. Often confused with Easter Lily (Lilium longiflorum), which blooms much earlier in the year, Philippine Lily blooms mid-July to August and sports classic lily-type flowers held high on study stems that may reach 7’ or higher. Emerging from the drab green of the surrounding summer landscape, Philippine Lily’s very large (10” or more), very fragrant, trumpet-shaped, creamy-white flowers are showstoppers. The propensity of the flowers to appear in elegant, “nodding” clusters of a dozen or more also adds to the effect. Admired by gardeners and other passersby during the day, at night these wonderfully scented flowers become a whirring site for evening pollinators, particularly the enormous Hummingbird, or Sphinx Moth.

In addition to being a beautiful surprise in natural areas, Philippine Lily is among the easiest and most versatile of landscape plants to grow. The species prefers partial shade, but the thousands growing along roadsides in full sun speak to its adaptability. It is also right at home in our often dry, sandy Panhandle soils, and no special soil amendments are needed for the species to thrive. To get plants started, one may use either seeds or transplants from existing stands. If using seeds, simply sow them in your desired garden location into loosened garden soil, cover lightly, and water – the same seed sowing method can be used in pots for transplanting or sharing with friends later. Alternatively, you can dig or pull bulbs from natural areas where Philippine Lily already exists – assuming you have permission from the property owner. These newly dug and planted Lilies will need babying with regular water for several weeks to reduce transplant shock and improve survival.
Philippine Lily is probably best sited in the back of landscape beds to take advantage of the plant’s height and display its flowers over lower growing perennials. Siting in the back also allows pre and post bloom Philippine Lily stalks to hide amongst other plants as they don’t add much aesthetically when not in flower. Philippine Lily pairs very well with other low-maintenance summer-blooming perennials like Black-Eyed Susan (Rudbeckia hirta), Garden Phlox (Phlox paniculata), Milkweed (Asclepias spp.), and others.
While not a native wildflower, Philippine Lily certainly adds to North Florida’s reputation as La Florida! They are among the easiest to grow, highest impact “wild” flowers Panhandle gardeners have at their disposal. Enjoy them this summer in natural areas and consider adding a few to your landscape!

It amazes me that even under flood conditions, people still water their lawns.
I’m sure you’ve seen it too – we get enough rain to cause some areas to flood and yet you see irrigation systems going full blast.

We should water our lawns, landscapes and gardens on an as-needed basis. The way that some people water their lawns is as logical as saying that a pet dog needs a drink of water at 4 p.m. everyday. This is not true. When watering, we are simply replacing water that is lost. This is true when we drink water ourselves, when we provide water for a pet dog, or when we provide water for our lawns, landscapes and gardens.
An irrigation system is a great tool when used to supplement rainfall. Irrigating too much not only wastes water but it also is the cause for many lawn problems such as shallow, weak root systems, leaching of fertilizer and numerous lawn diseases. Cutting the irrigation timer to off and operating the system manually will solve many lawn problems.
Also, there are tools to prevent an irrigation system from coming on during rain or when adequate rainfall has occurred. As a matter of fact, it has been state law in Florida for every automatic irrigation system to have a rain shutoff device installed since 1991.
Florida Statutes, Chapter 373.62 – Water conservation; automatic sprinkler systems states, “Any person who purchases and installs an automatic lawn sprinkler system after May 1, 1991, shall install a rain sensor device or switch which will override the irrigation cycle of the sprinkler system when adequate rainfall has occurred,”
Rain sensors are available, inexpensive and are not difficult to install. Rain shutoff devices really do work when installed properly. If you do not feel qualified to install such a devise on an existing system, check with a reputable irrigation company.
Water only when lawn indicates that water is needed. When the grass needs water, leaf blades fold along the midrib – like a book closing, footprints remain in the lawn long after being made and the lawn turns grayish in spots, indicating it needs water.
When 30 to 40 percent of the lawn shows these signs of water need, turn the irrigation system on and let it run long enough to apply one-half to three-quarters inch of water. Don’t water again until the lawn begins to show these signs of water need. Watering this way will develop a deep-rooted lawn and landscape.

When you hear the word “pollinator”, what is the first insect that comes to mind? If I had to guess, you would probably say honey bee. European honey bees play an important role in agriculture as pollinators and honey producers, but there are hundreds of native pollinators often overshadowed by the beloved honey bee you should know about, too!
One such group of pollinators native to Florida are sweat bees. Sweat bees get their unfortunate name from their nutritional requirements of salt that are sometimes sourced from sweaty humans. They rarely sting but are capable, and they can certainly be annoying to people when they lick salt off their skin. This behavior tends to get more attention than their important role as pollinators.
A subgroup of sweat bees are furrow bees. Furrow bees nest in the ground or rotting wood and may be solitary or eusocial. In-ground nests are composed of branching tunnels in sandy soil at a depth between 8 inches and 3 feet with a small entry roughly the size of a pencil. Within the tunnels, the mother creates individual cells stocked with nectar and pollen and lays an egg. The larva feeds on these provisions and pupates underground eventually emerging as an adult. The life cycle can vary from a few weeks to a year or more depending on species and environmental conditions.
Furrow bees are generalist feeders which means they will visit many different flowers, so diverse landscapes are attractive to them. In my northwest Florida garden, I see them often on sunflowers, Black-eyed Susan, coneflower, cosmos, tithonia, zinnia, and tickseed.

Landscapes can be a tricky topic. Doubtless, you’ve heard people debate the ecological benefits of a turfgrass lawn. An internet search will have your head swimming in opinion pieces detailing the benefits of keeping and removing your turfgrasses. Some outline the aesthetic virtues while others speak to pollinator support from native flowering plants. It can be overwhelming and there are a lot of factors to weigh in these decisions. Luckily this is a situation in which following the Florida Friendly Landscaping program means you may have your cake and eat it too.
Florida Friendly Landscaping
Florida Friendly Landscaping or FFL is a series of nine principles designed to maximize the ecological services of your landscaping while minimizing inputs. It all begins with selecting the correct plants and placing them in the proper place. Once in place, proper maintenance is covered by the following three principles which involve proper watering, fertilization, and mulching. Since we planted good larval and nectar plants our landscape attracts wildlife, which is the next principle. In this process, you’re likely to also attract insects you don’t want. Managing these responsibly is our next principle. The final three principles involve utilizing plant waste from your landscape, managing stormwater, and protecting waterways. Where a good deal of these involves proper maintenance and selection of plants, the purpose of this article is to highlight the two main ecological services outlined in these principles.

Support Wildlife
The first of these is attracting wildlife which for a wide swath of homeowners will focus on supporting pollinators. Pollination is critical for non-vegetative reproduction in plants. It’s the reason they produce vegetables or flowers. Many creatures aside from the well known ones perform pollination including bats, birds, flies, and beetles. Look into the needs of the pollinators you wish to attract and understand how these creatures eat, breed, and nest. These pieces of knowledge will help you decide on landscape plants. Create habitat by planting smaller areas with native and noninvasive plants which meet the needs of the pollinators you wish to attract. These areas need not replace all the turfgrass areas, and in fact, it’s better if they don’t.

Turfgrasses are Crucial in Your Landscape
Turfgrasses are ecological workhorses. They cool your environment, build soil, prevent erosion, aid water infiltration, and are arguably the best bio-filter in the plant world. Properly maintaining your grass is much easier than you may think. They need 1/2 to 3/4 inch of water per irrigation event, and generally only 1-2 pounds of nitrogen per 1000 square feet per year (Bermudagrass may need up to 5 pounds). Even this may be less pending soil testing. Keeping these grasses stress free through proper maintenance allows them to grow lush with little input.
Their benefit as a bio-filter comes into play with regard to storm water. This runoff is a seldom thought of as a pollution source. On top of moving debris and latent chemicals into local waterways, it washes dissolved organic nitrogen through the soil. All of this eventually finds its way into local waterways. Grass areas of your landscape slow free flowing storm water and filter pollutants preventing excess nutrient and pollution loads in the watershed.

Following the principles of a Florida Friendly Landscape can boost the aesthetics of your property and provide an ecological boon. Mix flowering and turfgrass sections of your landscape to meet these goals.

No Mow March was an awesome success this year! Together, by leaving some unmown areas of our lawns and landscapes, we helped create acres of additional valuable pollinator habitat in a critical time of the year. However, we can’t forget that there are still nine months remaining in which we can provide low-maintenance food and shelter for pollinators and other wildlife in our landscapes this year! The following are three of my favorite ultra-low maintenance pollinator friendly shrubs for Panhandle landscapes for summer and fall.
Chaste Tree (Vitex agnus-castus)
Chaste tree or vitex, an outstanding Florida-Friendly Landscape shrub/small tree, provides many aesthetic and wildlife landscape benefits throughout the growing season. Vitex features attractive grayish-green foliage and grows into a nice, rounded shape (10-15’ tall). However, the primary draw is its summer/fall flower show. Sporting striking masses of purplish-blue flowers for months on end until frost, Vitex is a pollinator magnet. Bees, butterflies, hummingbirds, and all manner of other pollinators visit vitex when in bloom and birds frequent the shrub in the fall to feed on its seeds. Simply select a site with full sun and well-drained soil and Vitex will reward gardeners and pollinators for years to come.
Firebush (Hamelia patens)
Firebush is a showstopper for both passers-by and pollinators. This sorta native shrub (Florida native but does not occur naturally in the Panhandle), is a prolific producer of tubular, bright-red flowers from late spring-through frost. These flowers are a preferred nectar source for many species of butterflies, Zebra longwing and Gulf Fritillary included, and a favorite of hummingbirds. Like vitex, birds also enjoy feeding on the berries that follow firebush flowers. In the Panhandle, firebush tops out at around 6’ tall and about as wide and is often killed back to the ground by frost, regrowing rapidly each spring. Firebush has no real insect or disease issues in landscapes and prefers the same sites as Vitex and will appreciate as much sun as you can give it and well-drained soil.

American Beautyberry (Callicarpa americana)
American beautyberry, or just Beautyberry as it is commonly referred to, is a lovely little deciduous shrub native to all parts of Florida and provides benefits to all manner of landscape wildlife. Though primarily known for its bird-attracting, vibrant purple berry clusters that appear late summer through fall, Beautyberry is a host plant for several butterfly/moth species and its dainty, pink flowers are an early summer favorite of many bees! Beautyberry grows 5-7’ in height and is extremely adaptable in landscapes as well, thriving in sun or light shade and many different soil conditions.

It’s important to remember that providing pollinator/bird food and habitat in lawns and landscapes is not a one month event, but a year round commitment. Reducing mowing frequency, reducing pesticide use, planting native trees, including host and nectar annuals/perennials in landscape beds, and yes, planting native fauna friendly shrubs like vitex, firebush, and American beautyberry are all part of maintaining a pollinator-friendly yard! Plant one (or several) today! For more information on creating pollinator habitat in landscapes or any other horticultural topic, contact your local UF/IFAS County Extension Office.
