Bald eagles and other large birds of prey have made a comeback in Florida.
Florida has all the elements of a wild animal’s paradise. The state has abundant rain and water sources, lush vegetation, plenty of food, and tons of nesting and hiding places. In our state and national parks, conservation easements, open waters, and acres of ranch land, large populations of animals can thrive. Particularly in areas with fewer people, healthy populations of even large animals like black bears, alligators, and panthers can maintain substantial territories. However, human migration into and throughout Florida is increasing at as steady a rate as ever. Retirees have long fled their cold northern winters to move part or full time to Florida. Now, the ability for many working people to telecommute from anywhere has made it attractive for younger families from all over the country to join us.

With more people comes the need for more housing. Some are content with high rise condos that leave a smaller footprint, but these are often located right on the water and can displace coastal wildlife and vegetation. For the thousands of families moving in weekly, more subdivisions, roads, stores, and schools are necessary. Inevitably, these lead to human-wildlife interactions that may or may not be positive experiences. In fast-growing south Santa Rosa County, I see almost daily reports of large black bears in backyards and trash cans. For smaller mammals, the threat of being hit by a car is unfortunately very common. For nearly every call we get about an exciting manatee sighting, we get word of a nerve-wracking interaction with a snake. As civilization moves closer to forested, once-wild areas, wildlife can be squeezed out, left without the protection of natural cover and drawn to human food and habitat.

There are plenty of ways we can co-exist, though. A Florida-friendly yard is a wildlife-friendly yard, and those who go the extra mile can even be recognized by the National Wildlife Federation for their efforts. There are several steps one needs to take to become wildlife-friendly. The most important include providing food, water, and cover, so the animals’ basic needs are met. Actions like removing invasive species, keeping pets supervised when outdoors, and adding layers of vegetation are also excellent ways to attract and protect native creatures.
While small and medium sized animals can find shelter in a single yard, it takes neighborhood cooperation to be a haven for something larger, like deer, bears, birds of prey, or large tortoises. Some neighborhoods are designated from the beginning to include conservation easements that serve as amenities to the neighborhood. They include trails, shady waterfront areas, and plenty of space for wildlife. It is important when moving into one of these neighborhoods that each homebuyer understands and respects the purpose behind conservation areas. Residents of older, existing neighborhoods can also work together to designate common areas and stretches of adjoining yards as wildlife-friendly corridors, allowing more animals to use the space safely.

In my own neighborhood in the city limits, a gopher tortoise has moved in and become a neighborhood mascot of sorts! When alerted to the presence of its burrow, the city brought in a sign explaining the animal’s protected status and crucial role in the environment. Floridians share their citizenship with thousands of other species. These breathtaking birds, fish, mammals, reptiles, and insects are integral to the health of our land and water. By taking steps to look out for their well-being, we are also providing for our own.

One big goal of establishing a home lawn and landscape is to enjoy an attractive setting for family and friends, while also helping manage healthy soils and plants. Soil compaction at these sites can cause multiple problems for quality plants establishment and growth. Soil is an incredibly important resource creating the foundation for plants and water absorption.

Soils are composed of many different things, including minerals. In Florida, these minerals often include sand of differing sizes and clay in the northern area of the counties in the panhandle of Florida. Soil is also composed of organic matter, nutrients, microorganisms and others. When soil compacts, the air spaces between the sand or clay are compressed, reducing the space between the mineral particles. This can occur anytime during the landscape and lawn construction phase or during long term maintenance of the area with equipment that could include tractors, mowers, and trucks.
What can be done to reduce soil compaction? There are steps that can be taken to help reduce this serious situation. Make a plan on how to best approach a given land area with the equipment needed to accomplish the landscape of your dreams. Where should heavy equipment travel and how much impact they will have to the soils, trees, and other plants already existing and others to be planted? At times heavy plywood may be needed to distribute the tire weight load over a larger area, reducing soil compaction by a tire directly on the soil. Once the big equipment use is complete, look at ways to reduce the areas that were compacted. Incorporating organic matter such as compost, pine bark, mulch, and others by tilling the soil and mixing it with the existing soil can help. Anytime the soil provides improved air space, root will better grow and penetrate larger areas of the soil and plants will be healthier.
Even light foot traffic over the same area over and over will slowly compact soils. Take a look at golf course at the end of cart paths or during a tournament with people walking over the same areas. The grass is damaged from the leaves at the surface to the roots below. Plugging these areas or possibly tilling and reestablishing these sites to reduce the compacted soils may be necessary.

Water absorption is another area to plan for, as heavy rains do occur in Florida. Having landscapes and lawns that are properly managed allow increased water infiltration into the soil is critically important. Water runoff from the site is reduced or at least slowed to allow the nutrient from fertilizers used for the plant to have more time to be absorbed into the soil and taken up by the plants. This reduces the opportunity for nitrogen, phosphorus, and other nutrients to enter water areas such as ponds, creeks, lagoons, rivers and bays. Even if you are miles from an open water source, movement of water runoff can enter ditches and work their way to these open water areas, ultimately impacting drinking water, wildlife, and unwanted aquatic plant growth.
Plan ahead and talk with experts that can help with developing a plan. Contact your local Extension office for assistance!

The hottest days of the summer are here and you might be thinking, “There is no way something could survive this heat!”. You might also be wondering “What can I do in my landscape?” Well, you are correct – it is hot and there are not many plants that thrive in this type of weather, but the good news is we are at the end of the summer season and there are things we can begin to do to get ready for fall. It’s not too late to get the last of the summer vegetables going such as lima beans, cucumbers, eggplants, and peppers. Many cool season crops can also be planted by seed now and tomatoes will thrive going into the fall season. See Vegetable Gardening in Florida
There are some heat-tolerant annuals like vinca, gaillardia, bulbine, and coleus that can be planted now in the landscape. See Annuals. Any time of the year, even late summer, bulbs like Aztec Lily, Butterfly Lily, Walking Iris, and Spider Lily can be planted. See Bulbs for Florida. Not many herbs do well in our Florida sun this time of year, but Bay Laurel, Ginger, Mexican Tarragon, and Rosemary can be planted as transplants now but not as seeds just yet. See Herbs.
August and late summer is the time of year that you may be seeing damage in your lawns. This could be caused by insects, disease, or irrigation failure. It is important to determine the cause, so the proper remedy is used. Some ways to avoid lawn damage are checking your mower blades regularly and making sure they are sharp. Also only cut the top one third of the blade of grass to not stress it in the heat of the day. It is good practice to test your irrigation clock and have a rain sensor. Some municipalities in north Florida prohibit the application of fertilizer during the summer rainy season from June to September so check with your local extension office. See Insect Management in Your Florida Lawn

There are some other maintenance measures you can take in August to help your landscape and prepare for the fall season. If older palm fronds are yellowing, this could indicate a deficiency in magnesium or potassium. Talk to your local agent or visit your local store for an appropriate palm fertilizer. See Palm Nutrition and Fertilization. Are you holding on to those beautiful fall mums or decorative Christmas poinsettias? Now is the time to pinch them back to allow time for buds to set for winter blooms. Finally, it is a good time to deadhead (remove old blooms) and fertilize flowering annuals and perennials. We’ve had substantial rain this summer, so keep in mind that the soil could be lacking nutrients. A soil test can give you data that indicates what you need for the up-and-coming growing season.

The number one request all would-be gardeners and budding landscape enthusiasts have is “I want something that I don’t have to take care of, tolerates the heat, blooms, and comes back every year”. That is a tall order in our climate but not an impossible one, especially if one is willing to take a step back in time and consider an old Southern passalong plant, Garden Phlox (Phlox paniculata)!

This old heirloom perennial is an outstanding ornamental for Panhandle landscapes. Every spring, Garden Phlox emerges from a long winter sleep and shoots its attractive bright green foliage straight up, reaching 3-5’ in height. After hiding inconspicuously in the landscape all spring, Phlox then blasts into fiery magenta bloom during the heat of summer, beginning the show in late June. While individual Phlox flowers are only 1” wide or so, they are held prominently above the plant’s foliage in large clusters up to 8” in diameter and are about as eye-catching as flowers come. The flower show continues through July and August until finally fading out as fall rolls around. Plants then set seed and ready themselves for winter dormancy, repeating the cycle the following spring. A bonus, though individual Phlox plantings start off as small, solitary clumps, they slowly expand over the years, never over-aggressively or unwanted, into a mass of color that becomes the focal point of any landscape they occupy!
In addition to being gorgeous, Phlox is adaptable and demands very little from gardeners. The species prefers to be sited in full, blazing sun but can also handle partial shade. Just remember, the more shade Phlox is in, the fewer flowers it will produce. Site accordingly. Phlox is also extremely drought tolerant, thriving in most any semi-fertile well-drained soil. Though it can handle drought like a champ, Phlox will languish if planted in a frequently damp location. If water stands on the planting site for more than an hour or so after a big rain event, it is most likely too wet for Phlox to thrive. Once established, Phlox is not a heavy feeder either. A light application of a general-purpose fertilizer after spring emergence from winter dormancy will sustain the plants’ growth and flowering all summer long!

Though the ornamental and low-maintenance attributes of plain Garden Phlox make it sound like a perfect landscape plant, it is uncommon in the modern nursery trade, having fallen out of favor as many old plants often do. The species is still a familiar site around old home places, cemeteries, abandoned buildings, and the like throughout the South, but is difficult to find in most commercial nurseries. The primary reason for this is that the commercially available modern Phlox hybrids sporting exotic flower colors and shapes are not tolerant of our growing conditions. These new Garden Phlox hybrids were bred to perform in the milder conditions of more norther climes and are extremely susceptible to the many fungal diseases brought on by Florida’s heat and humidity of summer, particularly Powdery Mildew. It’s best to avoid these newcomers and stick to the old variety with its pink flowers and ironclad constitution. Plain old Garden Phlox can be found in some independent and native plant nurseries, but the best and most rewarding method of acquisition is to make friends with someone that already has a clump and dig up a piece of theirs!
If you have been looking for a low-maintenance, high impact perennial to add to your landscape, old-fashioned Garden Phlox might be just the plant for you! For more information on Garden Phlox, other landscape perennials, passalong plants or any other horticultural topic, contact your local UF/IFAS County Extension Office. Happy Gardening!
