This is the time of year when gardens burst forth with lush green growth and colorful flowers.  With a little planning and management, your backyard pond can also put on the same show each year and fight unwanted pond weeds at the same time!

Fish and farm ponds are abundant in the Florida panhandle.  Most are two acres or less and are used for producing catfish, bass, and bream; for recreation and wildlife viewing; for fishing and swimming; and for irrigation and livestock watering.  Ponds play an important role in various aspects of agricultural production and rural life, and for that reason, maintaining their ecological health is critical to their many uses.

Managing aquatic plants is one important component of pond ownership.  If you are a pond owner, you have probably seen and read many articles related to controlling and removing aquatic weeds.  Just as in terrestrial gardens, there are a number of non-native (and sometimes native) plants that can become quite weedy and problematic in and around your pond.  Hydrilla, water hyacinth, torpedograss, Chinese tallow, alligator weed, and the tiny water spangles (common Salvinia) are just a few examples that plague our waterways and shorelines.  But, controlling and removing weeds is only part of the bigger picture of pond management.  Planting native wetland plants is another ecologically important and aesthetically enriching management tool as well.

By establishing beds of healthy native plants, you are also fighting against weedy non-native invasive plants through competition for space.  Some other benefits of native aquatic plants are they act as a barrier, filtering fertilizers such as nitrogen and phosphorus from runoff, and they help control erosion.  Also, because native plants are adapted to our local environments, they are generally easy to grow, and most require little or no extra water or fertilizer.

Below are a few guidelines to follow if you are considering the use of native aquatic plants in your pond.

Know Your Plants:

Depending on the type, aquatic plants generally grow in three forms.  Emerged, like maidencane or bulrush, submerged like coontail and southern naiad, and floating, like the tiny free floating duckweed, and spatterdock and fragrant water lily which are rooted with floating leaves and flowers at the water’s surface. There are many good UF/IFAS publications and online resources for aquatic plant identification.  Some are listed at the end of this article.

Plan Ahead:

Some questions to ask are, what is the primary use of your pond?  Is it wildlife viewing, swimming, fishing, irrigation, etc.?  The answers to these questions will help you determine how much of your pond and shoreline will be planted, and what types of plants to use.  For example, if you use your pond for fishing and irrigation, you should leave some areas of the shore unplanted and mowed to allow for access, and you should not plant submerged plants that may clog irrigation intakes.  On the other hand, if your pond is primarily for attracting wildlife, you can plant most of the shoreline including some types of submerged aquatic plants.

Right Plant Right Place:

You may have heard this Florida Friendly Landscaping term before, as it holds true for any garden including aquatic gardens.  Choose plants that grow best in the water depth and planting “shelves” you have in and around your pond.  By “shelf” we are referring to the slope of your shoreline.  Is it a gradual, gentle slope into deeper water, or is it steep and abrupt?  Also, become familiar with seasonal changes in your pond’s water depth, as it may affect the plants you select.

Prepare For Maintenance:

Just like a vegetable garden, your newly planted aquatic plants (especially those that are emerged) will need attention in the first year or so of establishment.  Remove dead plants and weed out unwanted plants.

Where to Purchase the Plants:

Northwest Florida–Where the Plants Eat Meat!

Northwest Florida–Where the Plants Eat Meat!

Among the most fascinating natural phenomena in our area are the presence of dozens of species of carnivorous, or meat-eating, plants. Found in bogs, meadows, and seepage slopes with mucky, acidic soils and low levels of nutrients, these plants have adapted to their difficult conditions by developing ways to digest insects.These carnivores are best known by their common names; sundew, butterwort, bladderwort, and pitcher plants.

Sundew Plants

While there are six species of pitcher plants found in the panhandle and throughout the Gulf Coastal Plain, the “world’s largest concentration” can be found at Escambia County’s Tarkiln Bayou Preserve State Park. The “pitcher” part of the plant is actually a modified leaf, which is rounded into a hollow tube open at the top and partially covered by a hood. This hood is colorfully patterned, attracting insects also drawn to nectar inside the tubes. As insects crawl in, downward-facing hairs prevent them from escaping. They drown in the collected water within the tubes, then decompose via acids and enyzymes secreted by the plant into a “liquid fertilizer.” A handful of commensal animals, including flies, spiders, and small frogs, take advantage of the pitcher plants’ insect-trapping expertise and manage to avoid capture.

A guide to identifying all six of these pitcher plant species–white-top, parrot, trumpet-leaf, hooded, sweet, and yellow–can be found at the Florida Department of Environmental Protection’s wetland plant site. Now is the perfect time to see pitcher plants beginning to blossom.

While many people are familiar with pitcher plants, fewer notice the low-growing sundew. These plants may be smaller than a dime in circumference, and grow flat along very mucky soil in full sun. If shaded out even by relatively short grasses, sundew disappear. Their characteristic pinwheel-like appearance and deep red coloring help draw the eye if you look very closely. Sundews also excrete a sticky nectar, on which small insects get stuck and digested to provide nutrients to the plants.The leaves of butterwort plants work very similarly to sundews; they are typically bright green and succulent with sticky hairs that attract nutrients.

Bladderworts, also found in similar environments, use a different mechanism to trap insects. They actually have a bladder-like formation within their root system that opens and closes, siphoning water and unlucky insects in and out.

Regardless of their location, appearance, or method of trapping, carnivorous plants remain one of the most unusual, and interesting groups within the plant kingdom. Be sure to take the opportunity this spring to seek out a park or natural area populated with carnivorous plants–such as Tarkiln, Blackwater River State Park, or the public areas of Eglin Air Force Base and see them for yourself!

 

 

Native vs. Invasive Plants

Native vs. Invasive Plants

 

CrossvineAccording to the Atlas of Florida Vascular Plants, there are more than 4,200 plant species naturally occurring in the state.  Nearly 3,000 are considered native.  The Florida Native Plant Society (FNPS) defines native plants as “those species occurring within the state boundaries prior to European contact, according to the best available scientific and historical documentation.”  In other words, the plants that grew in natural habitats that existed prior to development.Dogwood seed

Native plants evolved in their own ecological niches. They are suited to the local climate and can survive without fertilization, irrigation or cold protection.  Because a single native plant species usually does not dominate an area, there is biodiversity.  Native plants and wildlife evolved together in communities, so they complement each other’s needs.  Florida ranks 7th among all 50 states in biodiversity for number of species of vertebrates and plants.  Deer browse on native vines like Crossvine (Bignonia capreolata), Trumpet Creeper (Campsis saw-palmetto-palm-tree-pictureradicans), Yellow Jessamine (Gelsemium sempervirens) and Trumpet Honeysuckle (Lonicera sempervirens).   The seeds and berries of Black-eyed Susan (Rudbeckia fulgida), Flowering Dogwood (Cornus florida) and Dahoon holly (Ilex cassine) provide vital food for songbirds, both local and migratory.  Saw palmetto (Serenoa repens) provides cover for numerous birds and small mammals, as well as, reptiles.

Non-native plants become “naturalized” if they establish self-sustaining populations. Nearly one-third of the plants currently growing wild in Florida are not native.  Privet berriesWhile these plant species from other parts of the world may provide some of the resources needed by native wildlife, it comes at a cost to the habitat.  These exotic plants can become “invasive”, meaning they displace native plants and change the diverse population into a monoculture of one species.  Chinese privet (Ligustrum sinense), Popcorn trees (Triadica sebifera) and Cogongrass (Imperata cylindrica) have Cogongrassfloweringimagechanged the landscape of Florida over the past decade.  While Water hyacinth (Eichhornia crassipes) and Hydrilla (Hydrilla verticillata) have change water flow in many rivers and lakes.  These invasive species cost millions of taxpayer dollars to control.waterhyacinth4

By choosing to use native plants and removing non-native invasive plants, individuals can reduce the disruptions to natural areas, improve wildlife habitat and maintain Florida’s biodiversity.

Several  Master Naturalists have recently brought their projects to life. Several years ago, Charlie Lurton created a plan to build living shorelines in Bayou Grande behind homes in his neighborhood. The project was approved by state and federal environmental regulatory agencies and oyster reefs and planting have recently begun. Jerry Patee, also an Escambia County Master Gardener, worked with his church to create a boardwalk trail through wetlands to a pristine view of Bayou Garcon in Perdido Key.

Master Naturalist students vary in backgrounds from retired military and teachers to new residents and college students. Many Master Gardeners find the courses a helpful addition to their training, and utilize their newly gained knowledge when working with clientele. At completion, students receive an official Florida Master Naturalist certificate, pin, and patch. Several Panhandle courses will be offered this spring—check out the FMNP website to see when a class will be offered near you!

 

Is That Cotton Growing in My Trees?

Is That Cotton Growing in My Trees?

With the cotton harvest coming to an end, it’s not unusual to see cotton littered on the sides of the road.  You may also think you see it hanging in the trees, but you will be pleasantly surprised to find a hidden gem.  Woodbine (Clematis virginiana) and coastal virgin’s bower (Clematis catesbyana) are two native species of clematis that can be found wrapped around trees in the Panhandle.  They have finished flowering for the year and you will notice their showy seed lint hanging in the trees.

Clematis leaves are compound, consisting of 3 to 5 leaflets, dark green and glossy with toothed edges.  The vines are typically 1/2 inch in diameter and can grow to 20 feet.  The flowers are much smaller than those of cultivated varieties found at garden centers. Flowers are white with prominent stamens.  Clematis catesbyana and Clematis virginiana have similar flowers, but the flowers of C. virginiana are fragrant.

Clematis species grow well in partial shade to full shade.  Native plants are often found entwined in the forest understory near streams or ponds where soil conditions are moist.  Garden varieties grow well with their roots in moist, shaded soil and their leaves and flowers in the sun.  They are often seen growing on a trellis or on a fence.

It is important to note that some species of clematis are invasive.  Sweet autumn clematis or Japanese clematis (Clematis terniflora) is a vigorous invasive species that was once popular in southern gardens.  This species has similar characteristics to C. catesbyana and C. virginiana, but its leaflets have smooth edges.  You should develop a control strategy if Japanese clematis is found in your garden.  For control options, please visit EDIS – Japanese Clematis.
