The saw palmetto (Serenoa repens) is a classic symbol of Florida. Found in upland habitats and just to the edge of wetlands, their brilliant green fronds stand out in the mostly brown pine flatwoods and oak hammocks to which they are endemic. The shrublike saw palmetto thrives in sandy soils, is highly salt tolerant, and is tough as nails. The plant’s root is one of the sturdiest in nature. Imagine the trunk of a palm tree laid horizontally and just underground—this is the plant’s base. This root system lends stability and tolerance to nearly every tough Florida growing condition, including drought, floods, and fire. Saw palmettos are extremely slow growing, and there are stands in south Florida in which botanists have found individual plants and clonal colonies several thousand years old. Saw palmettos are one of the few members of the palm family that thrive in the panhandle. While many palm trees are planted here, most are native to more southern climates with warmer winters and karst geology—a higher pH soil composed of limestone and often prone to springs and sinkholes.

The saw palmetto’s name comes from the serrated, saw-like edges of the stem. These are quite tough and can cut your skin and clothing if not careful. A very similar palmetto, the bluestem, grows in wetter soils. It can be differentiated from the saw palmetto because its stems are smooth—no serrated edges—and the whole plant has a bluish cast to it.

The saw palmetto has long been prized by humans for its practical uses. The “ethnobotanical” history of this plant has ties to Native American tribes who used the fronds for roofing and building material, brooms, fishing nets, and fans. The leaves were utilized for rope, and multiple plant parts for food and medicine. The dark blue/black fruit of the saw palmetto was considered an aphrodisiac and has been used to treat prostate problems for centuries. According to a UF publication on the saw palmetto, “Modern day development of a purified extract from the berries greatly improves symptoms of enlarged prostate. Florida is the biggest source and producer of saw palmetto products. With about 2,000 tons harvested from South Florida and exported to Europe each year, the fruit crop estimate is $50 million a year in the state.”

Besides the human uses, saw palmetto serves as a crucial component in the diet of native wildlife. Florida black bears, panthers, 20 other species of mammals, over 100 types of birds, 25 amphibians, over 60 reptiles, and countless insects depend on saw palmetto berries as part of their diet. The wild harvest of saw palmettos is regulated by the state to prevent overharvesting and negative impacts to the wildlife food supply.

Saw palmettos also make a great home landscape plant, as they can grow in a wide variety of conditions, provide wildlife food and habitat, and add visual interest. There are few plants more “low-maintenance” than an established saw palmetto. A mature one is so difficult to remove, that it’s best to leave it where it is anyway!

Go Bananas in Your Landscape!

Go Bananas in Your Landscape!

Bananas are a great choice for your landscape, whether as an edible fruit producer or simply as an ornamental, giving your space a tropical vibe.

Bananas are native to southeast Asia, however, grow well across Florida. Complementary plants that can be paired with bananas in the landscape are bird of paradise (banana relative), canna lily, cone ginger, philodendron, coontie, and palmetto palm, just to name some.

Bananas are very easy to manage during the warmer months. Bananas are water loving, and that’s putting it lightly. Planting in vicinity of an eave on your home is a good measure for site suitability. Roof rainwater will drastically increase the growth of the banana tree and decrease the need for supplemental irrigation. Banana trees will need full sun and high organic moist soils create the best environment. For nutrition, a seasonal one-pound application of 6-2-12 fertilizer is a good practice to sustain older trees. Young trees should be fertilized every two months for the first year at a rate of a half-pound.

If there is a con to banana trees, it’s their cold hardiness. Some varieties fair well and others some not so much. ‘Dwarf Cavendish’ (Musa acuminate) is a popular variety that is found in many garden centers in the state. It produces fruit very well, but it is not very cold hardy. ‘Pink Velvet’ (Musa velutina) produces fruit with a bright pink peel, but isn’t very cold hardy either. A couple of cold hardy ornamental varieties are the ‘Japanese Fiber’ (Musa basjoo) and ‘Black Thai’ (Musa balbisiana), which is by far the most cold hardy, with the ability to easily combat below freezing temperatures.

Regardless of cold hardiness, in many cases, banana trees will turn brown after freezing temperatures occur or even if the temperatures reach just above the freezing mark, but will bounce back in the spring. Until then, it’s important not to prune away the brown leaves or trunk skin. These leaves act as an insulator and help defend against freezing temperatures. Usually, the last freezing temperatures that may occur in the Panhandle are around the first of April. So, to be safe, pruning can begin by mid to late April. When pruning, be sure to be equipped with a sharp knife, gloves and work clothes. Banana trunk skin and leaves can be quite fibrous and the liquid from the tree can stain clothing and hands.

So, what’s the best variety of fruiting bananas? Most ornamental bananas do not produce tasty fruit. If you are looking for a production banana, ‘Lady Finger’, ‘Apple’, and ‘Ice Cream’ are popular varieties, but are better suited for the central and southern parts of the state.

Choosing a Tree for Your Landscape

Choosing a Tree for Your Landscape

January and February are ideal months for adding a tree or two to your landscape in the Florida panhandle. In the cooler weather, the ground stays moist for a longer time, which helps prevent drought stress and the drying out of the rootball. Also, the winds are generally milder, and the tree will have a chance to get established and anchored in before the wilder winds of summer roll in.

Before investing time and money in a tree, take a few minutes and be sure that the species you choose is right for your particular landscape.

Here are some things to consider:

  • Whether the area can accommodate the ultimate size of the tree, both height and width, and not grow into overhead wires, streetlights, or your house.
  • Are there any underground utilities or septic? A call to 811 can check on where your utilities are.
  • The hardiness zone for the tree. Be aware that zone 8 or 9 in the western United States is a different climate with respect to moisture than the same zone 8 or 9 in Florida.
  • Whether the tree can thrive in your soil – sandy, loam or clay, loose or compacted, high and dry, or wet and low.
  • The amount of sun it requires.
  • Whether you want native species that provide food and habitat for native birds and animals.
  • Salt-tolerance if located on the coast.
  • Wind tolerance, especially if located on the coast. Many fast-growing trees are brittle and susceptible to breakage.
  • Whether you prefer an evergreen or deciduous tree. Evergreen trees, like hollies, provide a natural screen all year while some deciduous trees, like maple and bald cypress, provide fall color.
  • Is the tree messy, dropping large seed pods, fruit, or leaves?
  • The color and shape of leaves and flowers and other ornamental qualities.
  • Whether the tree species has known disease or pest issues.

Upgrade Your Gardening with Quality Pruners!

Upgrade Your Gardening with Quality Pruners!

There is an old saying that rings true in pretty much any situation – “You get what you pay for.”  Gardening tools, especially pruners, are no exception.  We’ve all been there, fumbling around with a pair of rusty, dull, cheap garden pruners that just barely get the job done.  Unfortunately, they can also do considerable harm to the plants you’re trying to improve, as anything short of a nice, sharp, clean cut introduces the potential for insect/disease infestation and will produce a wound that takes much longer to heal, if it ever heals properly at all.  You wouldn’t want your doctor to start hacking away at you with a dirty, second-rate scalpel.  Don’t subject your plants to the same treatment!  While I’m not advocating blowing hundreds or thousands of dollars outfitting your garden tool shed with top of the line everything, investing in a pair of quality bypass hand pruners will pay dividends many years into the future and make your gardening experience much more enjoyable!

Found in three designs, from old-fashioned anvil pruners that smush and smash their way to a cut, to ratcheting pruners that make short work of larger branches but tend to be cumbersome and complicated, to bypass pruners that produce clean cuts in a scissor-like manner, hand pruners accomplish many tasks in the landscape.  From cutting small limbs, to harvesting vegetables, to deadheading annual flowers and everything in between, there isn’t a more frequently used, versatile tool.  Therefore, it makes sense to buy a quality pair that will perform excellently, still be snipping long after your pruning days are over (if you take care of them), and that are comfortable enough you will enjoy using them.  When shopping for your pair of “forever” pruners, there are a few things to look for.

  • Only use bypass style pruners. Your plants will appreciate it.
  • Look for heavy duty pruners with frames made from quality aluminum or stainless steel; they won’t rust and won’t easily bend or break.
  • Buy pruners with replaceable parts. This is especially key because springs eventually rust and gum up and blades break and will eventually lose their ability to hold an edge over time (though you can and should resharpen them).

There are two commonly found brands that fit all three above criteria, albeit at different price points.  For a high quality “budget” blade, various models from Corona do an excellent job for the money ($20-30) and won’t hurt your feelings too badly if you happen to lose a pair.  Should you decide to splurge a little, Felco makes sharp, indestructible pruners, in multiple models around $50 to fit all size hands.  Felco has become the horticulture industry standard and you’d be hard pressed to find a nursery owner or landscaper that didn’t own a pair (or two).

Regardless of which brand you buy (and there are many more than the two above listed) a pair of well-made pruners, if taken care of, should last a lifetime and make your gardening experience much more enjoyable for you and your plants!  If you have any questions about gardening tools or equipment or any other horticulture or agronomic topic, feel free to contact your local UF/IFAS Extension Office.  Happy Gardening!

 

Not all Holly Plants Produce Berries for Christmas

Not all Holly Plants Produce Berries for Christmas

Holly plants are sometimes associated with Christmas. Their dark evergreen leaves and bright red berries fit right in with the Christmas Season. Some people intentionally plant hollies for the purpose of eventually using this desirable combination of green and red to create a more festive Holiday Season. But what if your hollies never produce berries?

The reason may be because you have a male plant. Male holly plants never produce berries. Holly plants are either male or female. The botanical term for this is dioecious.  If a male plant is selected, it will produce male flowers and pollen but never set fruit.

One way to know that you’ve selected a female holly is by purchasing a plant with berries. However, you still will need a male plant nearby or no berries will be produced.  Generally one male plant is adequate to insure pollination and good fruit set of berries on all female plants in a landscape. Your next-door neighbor may have a male holly plant that would serve as a pollinator for your hollies. Pollen produced by male flowers is transported by bees from distances up 2 miles. And because we are blessed with a number of native hollies in North Florida, chances are good that there will be a male holly within the appropriate distance in the wild to take care of the pollination.

The holly genus (Ilex) offers a terrific variety of plants from which to choose. Some horticulturists estimate that there are about 700 species worldwide. And there are a great number of cultivated varieties!  When selecting a holly for your landscape, it is important to know that most dwarf holly cultivars don’t produce fruit as they are propagated by cuttings from male plants.  Not all hollies have spiny leaves. For example, many of the Japanese hollies (Ilex crenata) have spineless leaves. There are hollies that grow tall, eventually making a tree. There are dwarf hollies that grow to only three to five feet in height. There are hollies with variegated leaves. And even though most hollies are evergreen, there are a few deciduous hollies that make nice additions to North Florida landscapes such as Ilex ambigua (Ambiguous Winterberry) and Ilex decidua (Possumhaw holly). Some hollies produce bright red berries but berry color varies from red, orange, yellow and even black or white, depending on variety. There are weeping forms available such as the weeping yaupon holly. There are those that have a very narrow, upright growth habit.

Creative Landscape Design Brings Dramatic Change

Creative Landscape Design Brings Dramatic Change

Landscapes are an ever-changing setting that can be fun to view as the seasons come and go.  We all have differing ideas of what an exceptional landscape should be.  The point to always keep in mind is what you and your family like.  Are you considering the Florida-Friendly Landscaping elements?  You always want to keep a healthy, attractive environmental sound landscape.  This brings many interesting design concepts to the table.

The kitchen table is exactly where a landscape design needs to begin.  My dad was just the opposite, he would receive or buy plants on impulse.  Load up all these three-gallon plants, take them home and plant without consideration the long-term growth, color combinations, time of bloom and many more topics.  He just loved working in the yard and growing plants.

There are basic principles of landscape design that are used as a guide. While I may stray from them from time to time, I always return to these principles.  Just keep in mind that a landscape is an ever-changing living setting that we will always work to improve.  The visual elements are based on what you see first when you enter a setting and are usually the vibrant high impact plants that may include bright bloom color, size of plant, focal plantings, leaf size and others.  The other side of the visual is the subtle presence of low impact plants with softer colors, small leaves, lower growing plant size.  This visual group often is planted en mass with a flow of plants to create a calming effect for the visitors to your landscape.

When the form of the plant is being considered, there are several points to keep in mind.  Will it have a three-dimensional impact in the landscape setting?  Is the landscape a small backyard or a one-acre open setting?  What are the maintenance requirements of the plant(s) as they mature in size?  A large tree can dominate a small area, but it may be just what is needed for shade with low plantings around it.   In a large setting, multiple large trees may be needed to create a focal point.  I have seen some wonderful tree alleys that help in directing the flow of the landscape down drives, walks, and paths.  These forms should be considered for all plants in the landscape including, trees, shrubs, groundcovers and even hardscapes.

Up next is the texture of the plant(s).  Are you looking for large and coarse or small, “softer” leaves?  You may find finely textured plants along paths or at entry areas to steps, softening the hardscape of the steps.   Are the large leaved plants open and airy, allowing light to flow through?  Large coarse leaved plants may be found at the back of landscape beds with fine textured smaller plants in front creating a three-dimensional look or even used as a focal point to pull the gaze of the eye to a determined location.

Color in the landscape has just as much impact as the plant texture, size and form.  Color can bring a bold or a soft statement.  The color is often thought of from blooms, but leaves too change in color with the seasons, from a fresh new bright green, purple, red or other colors in the spring to deeper, more mature colors as summer comes in.  Trunks can also bring unique colors to the landscape from subtle yellows to cinnamon.

There are so many things to think about when creating a long-term vision for your landscape.  Many options come in the decisions that will need to be made.  Do your research and always contact your local Extension office for more information!
