The Neighborhood Gardener – July 2019

It’s watermelon season in Florida. See recipes at Fresh from Florida.

This month in The Neighborhood Gardener:

Long dark green leaf with serrated marginsCulantro – Culantro is a tasty alternative to cilantro as temperatures rise. Fun fact: Did you know culantro is a key ingredient in sofrito, also called recaito? This popular mixture of vegetables is the base of many Caribbean dishes. Plant culantro seeds this summer and in about three weeks you could be harvesting fresh herbs to use in your kitchen! Learn more about this cilantro-like herb that can take the heat and flavor your food.

Sun shining high over pine treesHeat Safety – The summer garden seems to have an endless amount of work to be done. But working outside during the summer can put gardeners at risk from the unforgiving Florida heat. Be sure to take the necessary precautions and try to work in the morning before the temperatures get too high. Read more about the warning signs of heat exhaustion and heat stroke, as well as some precautions you should be taking before heading outdoors.

Unlike traditional impatiens, this hybrid thrives in full sun and humid, hot weather. Plus, they aren’t susceptible to downy mildew the way traditional impatiens are.

State Master Gardener program coordinator Wendy WilberWendy’s Wanderings — Most gardeners that I know grow at least a few vegetable plants, fruit trees, and herbs in their yard. Others have full blown mini-farms that are in max production through each growing season. For many years these edible growing activities have been relegated to the back yard. Never mind if the sunniest part of your yard was by the front walk — edible plants had to be grown in the backyard according to most Florida municipalities’ regulations. But no longer.

Attractive palm tree-like plant in front yard of a yellow housePlant of the Month: Ponytail Palm — The ponytail “palm” might not be a real palm, but it is a great South Florida plant. This tree-sized succulent is a member of the agave family and is named for the long, delicate leaves that drape over the branches, giving it a “ponytail” effect. Being from the dry regions of Mexico, ponytail palm is well suited for rock gardens or for the cooler parts of the state, as a container houseplant. South Florida gardeners can plant ponytail palm in full or part sun in well-drained soil; it’s hardy only in zones 10A to 11.

Grassy weed that looks a lot like St. Augustine turfgrassDoveweed — Doveweed is an aggressive summer annual turfgrass weed. It resembles St. Augustinegrass in appearance, so this weed can grow unnoticed for some time. But doveweed doesn’t just invade St. Augustinegrass, it also takes hold in Bermuda, hybrid Bermuda, and zoysiagrass. Doveweed usually prefers wet areas, so parts of your lawn that have poor drainage or are over-watered are prime spots for it to thrive. It can also cause contact dermatitis in some dogs. (Doveweed photo by John D. Byrd, Mississippi State University, Bugwood.org.)

Orange and yellow flower spikes of celosiaJuly in Your Garden — Despite the heat, some plants can still be planted, just be sure you’re taking care to not overheat your body. Annuals like celosia, coleus, torenia, and ornamental pepper can handle Florida summers. And even in the middle of summer, butterfly lily and gladiolus bulbs can be planted.

May means lots of plant sales and festivals – happy gardening!

This month in The Neighborhood Gardener:

An retention pond with lilypads and grasses, in front of a line of McMansionsProtecting Florida’s Water – The Earth is covered with water, but despite its abundance this resource is limited. In a state with so much access to water, it is easy to understand why we must all do our part to protect this vital resource. Gardeners can help protect and preserve the waters of Florida in many ways. Read on for more about preserving our water resources in Florida and some of the Florida-Friendly Landscaping™ Principles that address protecting water in the state.

A tiny fig leaf budding from the tree with sun shining through itWhat Can Your Plants Do for You? – Have you ever sat and considered what your plants are doing for you? Plants can be used in a number of ways; they can provide you with fresh food, beautiful scenery, lovely aromas, and much more. Factoring in how a plant will be used when designing your garden will create a more functional, energy-efficient landscape. We list some of the functions plants can serve and how to pick the right ones to fulfill all your landscape needs.

A brightly colored hibiscus with orange, yellow, and red in the petalsHibiscus — Hibiscus evokes an image of a vivid tropical paradise, with flowers that come in a rainbow of colors. Tropical hibiscus (Hibiscus rosa-sinensis) is what’s commonly seen in garden centers and landscapes. However, there are about 35 species of native hibiscus, also called rosemallows, in the United States. One hibiscus native to Florida, Hibiscus coccineus, is also known as the scarlet rosemallow, marsh hibiscus, or swamp mallow.

State Master Gardener program coordinator Wendy WilberWendy’s Wanderings — When you think of Sarasota you think of the beautiful beaches and lush tropical landscaping. Please also think of the amazing 150 Master Gardener Volunteers there that share their passion of tropical landscaping, edible gardening and community outreach with the residents of Sarasota County. The MGV group is led by Dr. Pat Williams and they are headquartered at the UF/IFAS Sarasota Extension Office off of Clark road. They were recently recognized by the Sarasota County commissioners for their impact in the community.

Tropical looking plant with long strappy leavesPlant of the Month: Bird’s Nest Fern — Bird’s nest fern can be grown indoors or outside. Large, stemless, bright-green fronds slowly uncurl from the center of this plant giving it a nest-like appearance. Native to tropical Asia, bird’s nest fern thrives in Florida’s humid climate in zones 9 to 11; plants in zone 9 will need freeze protection. Plant it in an area with partial to full shade and rich soil. This epiphyte makes a lush addition to the landscape, where it can shine as a specimen or a container plant, or indoors as a houseplant.

Plant with small new flowers on it after being deadheadedDeadheading: Not as Scary as it Sounds — Keeping your flowers looking fresh can help you be sure your landscape is looking its best. Deadheading can make a huge difference in your landscape with a minimal effort, something any gardener could rejoice over. Matt Orwat, Horticulture Extension Agent for Washington County explains the basics of deadheading. (Photo of coneflower, Matt Orwatt UF/IFAS Extension)

Deep purple torenia flowerMay in Your Garden — Summer is coming, and if you’re adding plants to your landscape be sure they can take the heat. Coleus, salvia, torenia, wax begonia, and ornamental peppers are a few of the ornamentals that can handle the high temperatures in South Florida. For heat-loving herbs, try basil, oregano, Mexican tarragon, or rosemary.

The Neighborhood Gardener – April 2019

Earth Day is Monday, April 22. Happy spring, gardeners!

This month in The Neighborhood Gardener:

The smiling face of Daisy Thompson, a 36-year volunteerForty Years of Memories – April is National Volunteer Month, and as we continue to celebrate 40 years of the Master Gardener Volunteer Program, we’ve chosen to highlight five long-serving volunteers from around the state. Between these five there is more than a century of volunteer experience! Read more about these wonderful volunteers, all the work they have done, and their favorite Master Gardener Volunteer memories.

A white clover flower with a tiny beePollinator Cover Crops – Cover crops can really make a difference in the quality of the soil in your edible garden. They have the potential to improve the physical, chemical, and biological properties of the soil, supply nitrogen, reduce leaching of nutrients and pesticides, reduce erosion, mitigate damage from plant pests and/or reduce their population densities, and attract beneficial insects. It’s that last benefit—attracting beneficial insects—that many gardeners choose to focus on. Learn about cover crops that pollinators love to visit, like buckwheat, clover, vetch, and lupin.

State Master Gardener program coordinator Wendy WilberWendy’s Wanderings — April is national volunteer’s month and this week in April is volunteer’s week. This provides me with the platform to stand up and proclaim that the Florida Master Gardener Volunteers are doing amazing volunteer work. Volunteering has its benefits to the person who gives back, too. Research demonstrates that volunteering leads to better health. In fact, the more you volunteer the happier you are. We know that Master Gardener Volunteers are life-long learners and continuing their education is one of the biggest benefits that Florida MGVs enjoy.

Small red cone with tiny yellow flower emerging from its sidePlant of the Month: Spiral Gingers — Gingers are typically low-maintenance plants with attractive foliage and long-lasting, colorful blooms that make great cut flowers. Plants in the Costus genus are often referred to as spiral gingers although the family (Costaceae) has been segregated from the true gingers (Zingiberaceae). Flower appearance with spiral gingers can vary; some form a rigid tube that is usually red to yellow in color, or they can be more open and spreading, in colors from white to pale pink. Learn more about this plant that adds a splash of tropical color to the Florida garden.

Posterboard display with the words Power to Pollinators on itGirl Scout Wins Gold with Pollinator Plan — The Girl Scout Gold Award represents the highest achievement in Girl Scouting. Emily Mayo with Troop 673 in Fort Myers is being recognized with the Gold Award for a project close to the hearts of many gardeners — advocating the importance of pollinators. She developed a lesson plan called “Power to Pollinators,” with help from UF/IFAS Extension Collier County and their Master Gardener volunteers.

A coleus plant with dark red foliageApril in Your Garden — April is the time to plant heat-tolerant annuals like coleus, while continuing to plant warm season edibles like sweet potatoes, Swiss chard, Southern peas, and beans.

The Neighborhood Gardener – March 2019

Spring is right around the corner, gardeners! (The first official day of Spring is March 20th.)

This month in The Neighborhood Gardener:

Pine straw mulch with bright green leaves of a plant peeking into the frameMulch Madness – Mulch is a magnificent addition to any landscape; it helps planting beds conserve moisture while also providing a beautiful texture and a bit of weed barrier. With so many types of mulch, it can be a bit overwhelming to decide which to choose. We help you decide which mulch is best—and which mulches may not be good—for your landscape. Learn which mulch is best to fill in your garden brackets.

A head of cabbage still in the groundCabbage – Did you know that St. Johns County leads the state in production of cabbage? Farmers call their busiest production time right before the holiday the “St. Paddy’s Day Push”! While it isn’t a good time for planting cabbage in Florida, it’s a great time for harvesting it in your garden or finding it freshly harvested from Florida farmers. Learn more about this vegetable so closely associated with St. Patrick’s Day.

State Master Gardener program coordinator Wendy WilberWendy’s Wanderings — The Florida Master Gardener Volunteer program is celebrating 40 years of service in 2019 and I will be highlighting several long-serving counties in this column. Brevard County on Florida’s Space Coast is home to Cape Canaveral, Cocoa Beach, and the UF/IFAS Brevard County Master Gardener Volunteers. Brevard is one of the original three counties that started their Master Gardener Volunteer program in 1979.

Three small white pinwheel-shaped flowersPlant of the Month: Crepe Jasmine — Crepe jasmine has abundant white flowers that are shaped much like a pinwheel. The flowers are particularly prominent in the warmer months of the year, but they stand out against the dark green, glossy evergreen leaves in any season. Forming a moderately dense, rounded, evergreen shrub that flowers even in filtered shade, this plant is a great addition to many gardens. Crepe jasmine plants thrive in Zones 9B to 11.

Sandhill crane's head and long curved neckFlorida Snowbirds — Quite a few birds can be seen migrating through Florida, and some even call our state home for the winter. While the term “snowbirds” can have more than one meaning, we’re referring to the feathered friends who flock to the state to enjoy a little warmth in the winter. Learn more about migratory birds who overwinter in Florida: sandhill cranes, cedar waxwings, and American robins.

Striped watermelon in the fieldMarch in Your Garden — North Florida gardeners are still experiencing winter, so hold off on planting those summer annuals just yet. Bulbs can be planted this month. In Central Florida, you can start replacing those declining winter plants with angelonia and gazania. Gardeners throughout the state can plant beans, squash, corn, and watermelon.

The Neighborhood Gardener – February 2019

Happy birthday…to us! The Florida Master Gardener program turns 40 this year.

This month in The Neighborhood Gardener:

Banana shrub flower is creamy white with waxy petalsGardening for Fragrance – Floral and herbal scents have been distilled and enjoyed indoors for centuries, and they can be equally delighting in the garden. Scent is one of the strongest human senses, and fragrant plants can add a new dimension to your landscape. With thoughtful planning and design, it’s not hard to create a pleasant fragrance garden. We have some plant suggestions for adding fragrance to your landscape.

Crabgrass uprooted and on concreteCrabgrass – As winter stretches on, you may find yourself with brown lawn areas that you swear were healthy green turf a few months ago. If so, the culprit is likely crabgrass. An important part of preventing crabgrass and other weeds from taking over your lawn is maintaining healthy turf. Unfortunately, once crabgrass has germinated and begins to grow, there are very few or no herbicides available to homeowners or commercial applicators that can kill it without harming most types of turfgrass grown in Florida.

State Master Gardener program coordinator Wendy WilberWendy’s Wanderings — The Florida Master Gardener Volunteer program is celebrating 40 years of service in 2019 and I will be highlighting several long-serving counties in this column. The UF/IFAS Hillsborough County Master Gardener program was started in 1980 by the beloved Dr. Sydney Park Brown, and has been going strong ever since. More than 100 active Master Gardeners in Hillsborough County have created a beautiful demonstration garden, introduced thousands of children to agriculture, and so much more.

Frilly green parsley leafPlant of the Month: Parsley — Parsley is a bright green, versatile herb that looks good growing and tastes good too. Parsley contains vitamins A, C, and K as well as several B vitamins, calcium, and iron. You don’t need much space to grow parsley; it even grows well in containers. One idea would be to grow it in a container with other herbs. And here’s a fun fact you may not know about this herb — it’s a host plant for caterpillars of the black swallowtail butterfly.

Green palm frondPalm Leaf Morphology — Palms are an iconic Florida plant, and there are many species and varieties of these tropical emblems. As you admire these trees and shrubs, have you ever wanted to know the difference between the types of palm leaves? Learn more about pinnate, palmate, and costapalmate leaves.

Red rose blossomFebruary in Your Garden — Prune roses this month to remove damaged canes and improve the overall form. After pruning, fertilize and apply a fresh layer of mulch. Blooming will begin 8–9 weeks after pruning. Plant winter annuals like dianthus and verbena. Many bulbs can be planted now as well, like agapanthus and crinum. Continue planting cool-season vegetables, including potatoes.

A White Christmas for South Florida

Sometimes the common name of a plant can give you a hint of when flowering occurs. For most of the year, Euphorbia leucocephala is a rather ordinary shrub. But as the holiday season approaches, its common name, little Christmas flower, makes perfect sense.

From early November, through December into the New Year, the shrub transforms into an airy white cloud of delicate, sweet fragrance. Like the poinsettia, to which it is related, the “flower” in little Christmas flower are actually bracts.

Once the bracts have all dropped, you can prune the shrub which can grow up to 10 feet until August, but not after that, or you’ll have no blooming the coming season. Wear gloves when pruning; the milky sap can be irritating. Native to Mexico, little Christmas flower is best for zones 10a-11. It grows best in full sun and well-drained soil. Avoid planting it under street lights, as it needs darkness to bloom just like its poinsettia cousins.

Neighborhood Gardener – December 2018

All-white poinsettia cultivar called 'Polar Bear'

Happy holidays, from the staff of the UF/IFAS Florida Master Gardener and Florida Yards and Neighborhoods programs.

This month in The Neighborhood Gardener:

Red bird with black around its beakCardinals Add a Splash of Winter Color – Bright colors are always a great addition to the landscape, but the color doesn’t always have to come from flowers or foliage; sometimes birds can bring on the color. Cardinals (Cardinalis cardinalis) are some of the most easily recognized birds. In winter cardinals stand out against the evergreens or leafless trees and in the summer their whistles are one of the sweet sounds of morning.

Yellow butterflyWhite and Yellow Butterflies – Whites and yellows provide some of the more delicate hues of the season. For more garden color that comes from creatures, we have a sampling of white and yellow butterflies found in our state. Whether you prefer the subtle markings of the checkered white butterfly or the bold colors of the tiger swallowtail, when planning to attract butterflies remember to plant both caterpillar host plants and nectar plants for adults.

Pale pink camellia flowerCamellia Problems — Camellias are a favorite cool-season bloomer, but while you are enjoying their beauty keep an eye out for signs of damage. This month we’re featuring a condensed version of the UF/IFAS publication, Key Plant, Key Pests: Camellia, covering some of the common diseases, pests, and deficiencies that afflict camellia plants. Knowing what exactly ails your camellia may help you treat the problem more effectively.

State Master Gardener program coordinator Wendy WilberWendy’s Wanderings — It is the gift-giving season and if I could give gifts to all my gardening friends it would be for agreeable weather, fertile soil, and plenty of time to work in the garden and landscape. When folks find out you garden they love to give gardening gifts, but do they give garden gifts you love? Here are some of my favorite suggestions for useful tools for the gardener, and if you don’t find these under the tree maybe you will take yourself shopping with a gift card.

Small round green shrubPlant of the Month: Dwarf Hollies — Hollies are well known for their evergreen leaves and bright red winter fruits. They come in many forms and low maintenance. For smaller spaces and even containers, consider a dwarf holly. These smaller shrubs can also be used as hedges and foundation plantings, and there is a dwarf holly for all areas of Florida. ‘Bordeaux’, ‘Nana’, ‘Schillings Dwarf’ (pictured at left), and ‘Taylor’s Rudolph’ are just a few of the available cultivars.

A coleus plant with bright gold leaves edged in red in a plastic potCommon Landscape Pitfalls: Selecting Plants for Purchase — Landscapes with plants that match their preferred growing conditions require less water, fertilizer, pesticides, and maintenance than landscapes with plants growing in the wrong locations. When choosing the right plant for the right place, there are a number of factors to consider to ensure a long-lived, healthy landscape. Starting out with quality plants plays a huge role in the long-term well-being of your plants.

Bright yellow cassia flowers against a blue skyChristmas Cassia Causes Confusion — As winter approaches in Florida, plant lovers cannot help but notice the golden spectacle of the Christmas cassia (also known as Christmas senna, climbing cassia, or valamuerto). This shrub or small tree bears clusters of showy, bright yellow blossoms, on often-arching branches. Flowering begins as early as mid to late October and in frost-free parts of the state may extend through April, but in most areas peak bloom coincides with the holiday season. Extension botanist Marc Frank explains that your Christmas cassia is likely an invasive plant.

Poinsettia with pink and cream bractsDecember in Your Garden — Reliable cool-season vegetables to plant this month include cabbage, collards, kale, and broccoli. Enjoy one of the most popular indoor holiday plants, poinsettia. Protect it from cold until spring, and then plant it in the garden for next year. Inspect regularly for pests on indoor plants. Keep in mind that plant-specific temperature, light, and humidity are key to ensuring that indoor plants thrive.

Friday Flowers: Powderpuff Tree

powderpuff_calliandra500
This powderpuff was photographed in Kanapaha Botanical Gardens. UF/IFAS.

Powderpuff tree is a reliable magnet for hummingbirds, and easy to grow.  Its main attraction are flowers that appear in late fall and persist into the winter, giving it the South Florida nickname of “snowbird tree.”

Powderpuff (Calliandra haematocephala) is native to Bolivia, but has been cultivated widely. It is evergreen, with fine, delicate foliage that starts a copper color before maturing to dark green. When flower buds appear, they resemble raspberries, before expanding into puffs of silky stamens. Typically red (“haematocephala” refers to blood), there are some powderpuffs with watermelon-pink and even white flowers.

Trained as a tree, it has an arching, graceful habit, creating a canopy suitable for patios and even containers. It’s easily kept to a desired size with hand pruning.

Powderpuff can be grown as a large shrub or small tree in zones 9-11. In zone 9, frost can kill it back, but shoots will appear from the base in spring. With rapid growth in sandy soils and full sun, powderpuff will respond favorably to regular watering while young but should require no special care once established. Once established, it’s drought tolerant, but has also been reported to survive the occasional standing water from heavy rain as well.

For gardeners who miss their beautiful-but-invasive mimosa trees, powderpuff is an ideal alternative. It has been evaluated using the UF/IFAS Assessment of the Status of Non-Native Plants in Florida’s Natural Areas and is not considered a problem species.

There is (of course) a popular dwarf cultivar, Calliandra haematocephala ‘Nana’. While it doesn’t flower quite as spectacularly as the larger powderpuff, it does flower year-round.

Poinsettias for the Holidays

pink and white poinsettiaVery few plants are as closely associated with a holiday as poinsettias are with Christmas. The poinsettia, native to South America, was given the botanical name Euphorbia pulcherrima, which literally means “very beautiful.” Its popular name honors Joel Roberts Poinsett, the first U.S. ambassador to Mexico, who introduced the plant here.

Poinsettias make great holiday decorations and they’re often given as gifts in late November and throughout December. The showy portions of the poinsettia, which most people think of as the flower, are actually colorful leaves called bracts.

If you are in North Central Florida, you have a unique opportunity to see (and buy) poinsettias in other colors besides red and white. On December 6th and 7th (Thursday and Friday), the University of Florida’s Environmental Horticulture Club is holding their 22nd Annual Poinsettia sale.

Over 40 varieties will be offered for sale including traditional reds and novelties such as Peppermint Ruffles and Orange Spice.

Get the details at their website: https://sites.google.com/site/ufhortclub/poinsettia-sale

If you’ve purchased a poinsettia, or perhaps received one as a gift, you may have some questions on how to properly care for it. Your local UF/IFAS Extension office has agents and volunteer Master Gardeners that can answer questions on how to care for your plant beyond the holidays. They may even be holding classes or workshops, like UF/IFAS Extension Pasco County. Their class, Caring for Holiday Plants, will be held January 2nd (get details here). Don’t know where you county Extension office is? Find it on this UF/IFAS map.

You can read more about poinsettias on the UF/IFAS Gardening Solutions website, too.
