Planning and Planting for Wildlife

Planning and Planting for Wildlife

Planning landscaping is undoubtedly not easy. The primary concern relegated to each individual homeowner is what you want out of your yard. Many are content with just grass, while others desire a diverse array of plant life. One aspect oft overlooked is your landscape’s capacity to be a boon for local wildlife. With a bit of planning, your property could be literally buzzing with insect pollinators, wild birds, and even our reptilian friends.

Where to Start

For this article, let’s begin with a newly established development. What has happened in this scenario from an ecological perspective, with what we’d call primary succession? In short, this means an area that experienced a complete reset of its plant communities. In nature, this would be the result of events such as a volcanic eruption, but in Florida, it’s far more likely due to bulldozers.

Now, the good news in this scenario is that you won’t be receiving your property in this condition. The developer has fast-tracked the process by planting grasses and some basic trees by the time you’ve purchased the property.  It’s from this basic setup that you, my new homeowning friends, can begin your husbandry of our local animals.

Begin by investigating the where your new home was built. If it began as a wetland, you’ll want to select plants appropriate for that environment.  The same is true if you’ve moved into what was forest land. This thought aligns directly with the first of our FL Friendly Landscaping principles: right plant, right place.  There is little sense in putting plants that don’t like wet feet into a poorly draining soils common in wetlands.

Consider Your Environment

You’ll also want to investigate the wildlife that is endemic to those environments and areas.  Knowing what is there, and what you’d like to attract to your landscape, will help you decide which plants will be best. For instance, replacing a crape myrtle (Lagerstroemia indica) with a red maple (Acer rubrum) in what was previously a wetland environment puts a tree better suited to that environment, which will require less maintenance from the homeowner.  Additionally, red maples are known to be an early-season nectar source for a multitude of moths and butterflies while providing nesting sites for local birds.

Red maples are a great example of plant selection and what it can do to attract wildlife to your yard, but there are other guidelines with which you’ll want to be familiar should this be your goal.

Guidelines for Attracting Wildlife

Water is critical to all life on the planet, including wildlife. Providing water features in your garden will increase the chance for animals visits to your garden. This can be as basic or as elaborate as you’d like.  Everything from a pond to a simple dish of water will suffice. One common water feature challenge to consider for Florida gardeners are mosquitos. Avoiding these pesky creatures could be as easy as creating flowing water features. Solar fountains are an easy and cheap way to accomplish that goal.

Shelter is another critical aspect to attract wildlife. Either natural or man-made, it is essential to attracting and keeping various species in your yard. Bird, bat, or owl houses are perfect solutions to this issue. Just ensure you site them correctly to provide the correct environment for the animal in question.

Design your landscape to be layered. In this instance, this means integrating shrubs, trees, herbaceous plants, and groundcover. Doing so will provide some cover for feeding while providing visual interest to your home.

Last and certainly not least, choose plants known to be a food source. When doing so, you’ll want to research how those animals you’d like to attract eat. For instance, hummingbirds (Trochilidae) have a small, curved beak.  If this is the species you’d like, you’ll want to select plants rich in nectar with tubular flowers. Firebush (Hamelia patens) is an excellent example of a plant for this purpose.

Conclusion

Bringing local wildlife into your yard is an excellent way to get to know the small creatures living in your area. A few simple changes may go a long way toward reintroducing habitat to an area where it may be waning.  For more information on attracting wildlife or any horticulture topic, refer to your local Extension office

Why Say No to Invasive Species

Why Say No to Invasive Species

Identifying the plants present in your gardens and landscapes is a critical skill. These plants are the sculptors of our local environment. As such, it’s important to understand how they affect local ecology, and what services they may provide. Three overarching categories you’ll find as you delve into plant ID are “native”, “introduced”, and “invasive”. The latter of these is the subject of this post.  Invasive is often a misunderstood term but hopefully this will clear up some of that misconception.

Definitions

Before any other conversation can even take place, it’s important to define terms.  The first, and most important of these is “Invasive”. Believe it or not, there is an official definition laid out by the USDA under Executive Order 13112. It states, “an alien species whose introduction does or is likely to cause economic or environmental harm or harm to human health.” Alien in this instance being any propagation material of a species not native to a particular ecosystem.

Invasive contrasts with “Native” or “Introduced” species which either naturally occur in an ecosystem or were brought to said system through human activity.  Keep in mind that many introduced species have served gardeners very well providing food, beauty, and pollinator support without the risks associated with invasive plants. You can find all these terms defined on the USDA’s website.

What’s the Damage

So why is it important to know these species, and more importantly what can gardeners do about them? The primary issue with these plants is how they impact our natural areas. They compete for real estate crowding out more desirable species. They also deprive these species of resources such as sunlight or nutrients often denying nectar to our pollinators.

Not worried about the impact on natural areas? On an economic front, it costs Florida’s taxpayers roughly $179 million per year to manage invasive species, the majority of which is applied to plant species.  This number may seem high, but considering a single invasive insect has cost the citrus industry billions in lost production it seems appropriate.

Economics not persuasive?  Some invasive plants such as castor bean (Ricinus communis) are very dangerous for humans. Ingestion of this plant carries a high potential of illness and often results in fatality.

Summing it all up

The bottom line is that invasive plants are not innocuous.  The plants we grow in our landscape can and do have detrimental effects on the surrounding environment, the economy, and are potentially deadly to humans.  It’s incumbent upon all gardeners to know how to identify these plants. Once you have identified them, it’s important to learn how to eliminate them so they don’t return.

There are many resources out there to help with identification.  UF/IFAS has an assessment tool here. This tool allows you to search for individual plants and provides their known status. Another great way to discover the invasive status of your plants, is through the Florida Invasive Species Council or FISC.  They are the convergence point between scientists, land managers, and local governments which inform a list of plants with invasive tendencies.  That list may be found here.

Managing Storm Water in Landscapes

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.

It’s Time for Sweet Potatoes

It’s Time for Sweet Potatoes

Sweet potatoes (Ipomea batata) are a much ballyhooed southern food staple. Valued primarily for their tuberous roots, they also boast an edible leaf. That, however, is not the end of their story. Some cultivars find use strictly as an ornamental. While not the subject of this article, you will typically find these dangling over rock walls or cascading from a hanging basket. While these can be quite impressive, this article will focus on the edible version of this plant, and its nutritional benefits.

What Cultivar?

As with any vegetable, these have been heavily bred to optimize growth and yield in our southern environment. In Florida’s Panhandle, ‘Centennial’ and ‘Beauregard’ are two varieties that perform admirably. They have a vining growth habit and are very productive. For those gardeners with less space, ‘Vardaman’ sweet potatoes. This cultivar has a bushy growth habit rather than a trailing vine.  

Planting

Sweet potatoes are not planted by seed, but rather from a “slip”. These are the vegetative growth from the mature sweet potatoes. While it is possible to grow these yourself, it is better to utilize certified disease-free slips from a reputable garden supply store. Use slips that are 6 to 9 inches long, planting them in rows 48 to 54 inches on center, with plants spaced 12 inches apart.  

Sweet potatoes can be planted in early spring through late June. These plants thrive in sandy soils, which are typical in the Panhandle with very little fertilization (approximately 0.04 lbs. of N on a 10 x 3-foot row). The downside to sweet potatoes is their exceptionally long growth season of 100 to 150 days after planting.

Pests

There are some pests which you’ll need to be wary when growing sweet potato. Most notably of these is the sweet potato weevil (Cylas formicarius). Even small amounts of damage from this insect can induce sweet potatoes with a foul taste. Control them through cultural practices such as turning your soil several months prior to planting, and adequate irrigation. Wireworms and beetle larvae are also concerns with sweet potatoes. Sample for grubs throughout the growing season, remove vegetation post harvest, and rotating your crops will keep these pests at bay. If all else fails, there are insecticidal options available. Consult your local extension agent to choose the appropriate option.

Time to Cure

Post harvest, sweet potatoes should be placed in a dark 85° room with 90% humidity for about two weeks. This is known as curing and will convert some of the starches of this vegetable to sugar making it slightly sweeter. Once the curing process is finished, store them in a cool, dry pantry at temperatures below 50°. This will keep them a viable staple in your pantry for several months.  

The end result of all this work will be a food high in vitamin A, vitamin C and fiber that can be used for anything from home fries to pies.  

To Sum Up

Growing your own vegetables in your own garden is a very rewarding experience. Sweet potatoes are an easy way to produce a lot of food for your family. If you’d like to know more about growing sweet potato, please consult these document.

Ecological Benefit and Upkeep of Florida Lawns

Ecological Benefit and Upkeep of Florida Lawns

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.
