If you have walked through any retail garden centers lately, you probably have seen some bright colored fall flowers. These pretty plants are what we call mums, or chrysanthemums. Mum flowers are a fall staple in the south to see on a front porch or any fall decorated scape. They pair great with an heirloom pumpkin or some ornamental kale. Growing up in Kentucky, mums are everywhere you turn this time of year. But how can you make the most of your mums this fall? Follow along for great tips to keep your mums fresh for the next several weeks.

When shopping for the perfect mum for your porch, it is best to try and select a pot that has not fully bloomed yet. Chrysanthemums come in a variety of colors and some varieties even bloom more than one color (I love Candy Corn Mums!), but it is crucial to choose a plant that is not showing any color at all yet. The more blooms, the less life span you will get. Many wholesale mum growers will “de-head” the blooms or remove the buds appearing closest to opening when they are closer to market time to keep the inventory prettier for the consumer. It’s also important to select plants that look healthier. Mums bloom in a mounding fashion, so having uneven bloom patterns or discoloration is not a good sign. It’s also good practice to remove blooms as they begin to die off to make room for new ones.
In the last several weeks in Jackson County there has been little to no rain fall. It’s important during dry spells like these to keep your mums saturated but not sopping wet. Mum flowers love to be watered from the bottom. To do this, set the pot in a bucket of water no longer than 15 minutes at a time to allow the soil to hydrate thoroughly. Watering your mum from the top can increase chances of bacteria and fungus growing on your blooms and can cause uneven blooming patterns. Mums need full sun to grow, so monitoring their dryness is important so your plants don’t dry out completely.
Okay, so Halloween is over, you hear the turkey gobbling, and Santa’s sleigh is on the horizon; this doesn’t mean throw out your mums! You can easily keep your mums in containers until December, but there is a risk of frost. When the temps drop below 40 degrees Fahrenheit at night, covering mums with old towels or sheets and removing them in the morning is best practice to keep your blooms frost-safe. You can also plant your mums in the ground. If you chose to do this, it is best to amend with compost as most mums are not acclimated to sandy soil.

It’s getting close to that time of year again! You may be the giver or receiver of a wonderful holiday plant soon. Dish gardens, potted flowering plants (such as azalea, begonia, poinsettia, or chrysanthemum), plants with attractive foliage, and even patio citrus make great gifts. However, special care is needed to keep them healthy throughout the holiday season and beyond!
For plants intended to be “house plants”, over watering, over fertilizing and poor placement are the most common problems encountered by caretakers. The first thing you need to keep in mind about gift plants is that most of them have been growing in a carefully controlled greenhouse environment for some time. These types of plants are acclimated to a specific temperature & humidity level. Therefore, they’re sensitive. When they’re moved into your home atmosphere, they typically go into a level of shock. If you received a gift plant, you’ll have to help it overcome this shock by paying careful attention to the important factors- light, temperature, water, and fertilization.

Indoor areas often restrict light and provide very low humidity. Plants with dense foliage prefer light, but not continuous direct light all day. Placing a plant near a window or near light fixtures should suffice for photosynthesis requirements. However, flowering plants such as mums and poinsettias will stand more light than most foliage plants and should be placed in very bright areas. Most indoor plants grow well in temperatures of 60 to 70 degrees. Be careful to not place plants in drafty locations where sudden changes in temperature occur. Also, don’t place plants close to radiators or air conditioner vents/returns. These areas typically dry soil excessively and could cause plants to wilt.
Watering is one of the major causes of failure with plants in the home, especially for containers which don’t have drainage holes. Most house plants will require a thorough soaking once a week. Water only when necessary and don’t let the pots stand in saucers of water unless the plants are very tolerant to excess water. Overwatering can kill plant roots, increase chances of disease, and eventually kill the entire plant.
Proper fertilization is another important part of growing healthy plants. Fertilizer labeled for house plants or 10-10-10 are good, general-purpose, complete fertilizers to use. Always follow all the directions on the bag or container, so that you don’t over fertilize, causing the plant’s demise.
Following these basic practices to keep house plants healthy should keep your gift plant looking attractive for the remainder of the holiday season and beyond.

While the Florida Panhandle isn’t considered a true tropical climate, now that the summer rains have started, it sure feels tropical outside. To create high performing colorful containers in these conditions, it’s wise to pick plants that hail from tropical climes – one of my favorites is Crossandra (Crossandra infundibuliformis).
Native to tropical Sri Lanka and India, Crossandra is built for hot, humid conditions. An evergreen subshrub growing about 3’ tall in its native range, Crossandra sports glowing orange flower clusters held high on stems that rise above deep green, glossy foliage – a very striking combination. These showy orange flowers arrive once temperatures heat up in the early summer and continue emerging en masse until cool nights stop the show in fall. While deadheading spent flowers can enhance Crossandra’s free-flowering nature, I haven’t found it totally necessary to ensure consistent flowering. In addition to being beautiful, Crossandra’s flower clusters are also attractive to a wide variety of pollinators, including butterflies and dragonflies.

Adding to Crossandra’s appeal, the species couldn’t be easier to grow if you give it the right conditions. Crossandra prefers to be sited in areas that receive ample sunlight but also get a reprieve from the hottest afternoon rays. This year, I grew one on a deck that receives sun from about 10 am – 2 pm and is then provided filtered shade from a large tree the rest of the afternoon; these conditions seem to be ideal. Crossandra performs best in moist, well-drained soil, making potting mix an excellent option. Daily watering in the summer combined with our (hopefully) frequent rainfall in July and August keeps it wilt-free. I also apply slow-release fertilizer at planting and then supplement with liquid fertilizer periodically throughout the summer. This, combined with regular irrigation, promotes healthy, vigorous growth, and allows the flower show to continue uninterrupted until cool weather finally draws the curtains.
Crossandra is a versatile plant in container gardens, shining in either the role of filler in larger containers or as a solo specimen plant in its own container. In mixed containers, play off of Crossandra’s orange flowers with partial sun foliage plants like Coleus, Elephant Ears, or Hawaiian Ti, or flowering annuals like Browallia ‘Endless Illumination’, Torenia (Wishbone Flower), Blue Daze, or Purple Heart Plant. While Crossandra does well in mixed containers, as a UF graduate, I prefer to stick it in my favorite blue pot for an orange and blue Gator themed solo container!
Regardless of how you choose to incorporate Crossandra into your garden’s design, it will reward you with summer-long orange flowers in a low-maintenance package. Simply place it in morning to early afternoon sun, give it ample water and adequate fertilizer, and enjoy this Florida Friendly Landscaping approved species. Plant one today!
For those of us that don’t have the best landscape conditions or the time, money, or inclination to invest into a vibrant yard display of annual flowers, growing our flowers in containers is a great option! Growing in containers has several advantages over growing flowers in the ground. It gives gardeners control over the soil, fertility, and water conditions that the plants are grown in and the ability to add pops of color/texture anywhere – in an existing planting bed, patio, deck, porch, or even indoors. Let’s explore some simple tips to create containers that will offer low-maintenance explosions of color all summer long.
The easiest way to create full, colorful containers is by using the design scheme known as the “thriller, filler, spiller” arrangement. This design first utilizes a dramatic “thriller” in the back of the container, usually a plant that has a taller, upright growth habit and striking flowers or foliage. Commonly used thrillers are plants like Purple Fountain Grass, Salvia, Canna, and Hawaiian Ti. Next come the fillers. Fillers are plants that possess a mounding habit and generally provide the floral firepower in the container. Popular fillers include Vinca, Begonia, ‘Diamond Frost’ Euphorbia, Lantana, Pentas, Impatiens (for shady containers), and even foliage plants like Coleus, Caladiums, and Ferns. Finally, spillers round out the containers by “spilling” over the sides. These are typically vining or trailing plants and add a final dramatic touch to the overall container style. Some of my most-used spiller plants are Creeping Jenny, ‘Silver Falls’ Dichondra, ‘Gold Dust’ Mecardonia, Torenia (aka Wishbone Flower), and Sweet Potato Vine.

Will all those plant options, how does one choose plants to combine in containers? When perusing the nursery to pick thriller, filler, and spiller plants, all you need to remember to be successful is the basic layout of the color wheel and the phrase “right plant, right place”. Knowing the color wheel is important because some colors look better than others in combination! For instance, most classic color combos are known as “contrasting colors”, just meaning opposite each other on the color wheel – think the Orange and Blue of the Florida Gators or the Purple and Gold of the LSU Tigers. It’s hard to go wrong pairing plants of contrasting foliage or flower colors. Another option is to use different shades or hues of the same color, this is known as a monochromatic color arrangement. Monochromatic arrangements create a stunning punch of color and can even be used to highlight colors or features around the container, like the brick or siding color of your home.
After choosing your color palette, it’s critical to make sure you have the right plant in the right place. For container gardening, this just means pairing plants with like needs. For instance, you wouldn’t want to grow shade loving Impatiens in the same container as sun loving Purple Fountain Grass. Likewise, pairing a succulent with a heavy water user like Coleus is a bad idea. Combine plants with like growing condition preferences and you’ll save yourself a major gardening headache!
Maintaining your summer containers is also relatively easy. At planting, fertilize with a slow-release fertilizer like Osmocote or other similar product at the label rate and water in. After the first month or so, I begin supplemental fertilizing every couple of weeks with a liquid fertilizer. As your container grows, the days get hotter, and there are more roots to suck up water, your watering frequency will increase from once every couple of days to every day, and, on very hot days, twice a day (morning and late afternoon/evening). All this watering and fertilizing sounds like a lot of work, but I enjoy getting out and spending a few minutes with my plants! It’s a great way to start your day/wind down after work and allows you to spot any issues before they become major problems!
Gardening with containers is without a doubt the easiest way to create summer long color on your deck, patio, or landscape. Giving us the ability to control soil, water, sun, and fertilizer conditions, growing our annual color in containers removes many of the variables that makes gardening difficult and provides pops of color and texture in any setting – design and plant a few containers this summer!

Florida is a fun state to live in for many reasons. You are never more than an hour or two away from a great beach, it never gets bitterly cold, and the fishing is phenomenal. I could go on. More than all that though, my favorite thing about living in Florida is the ability to have something blooming year-round, even in the cool months. This year, the stars of the spring show in my backyard container garden have been new selections of an old favorite, the Petunia.
Petunias, a close relative of Tobacco, originally hail from South America. And while the original petunia species were not a valuable crop like Tobacco, enterprising European explorers realized the group had horticultural potential. By the late 1800s, plant breeders had begun hybridizing wild petunia and the petunias gardeners now recognize took shape! Fast forward to today and petunias are the most popular bedding plants in the US, with annual petunia sales topping $260 million (USDA’s Census of Horticultural Specialties). More than 700 petunia cultivars have received plant patents, comprising all manners of sizes and flower colors. This year, there is even a controversial genetically modified petunia called ‘Firefly’ hitting the market that displays bioluminescence – it literally glows in the dark!

In the past, petunias struggled in the Deep South, as they were often ravaged by various fungal pathogens induced by our too-warm weather. These old-fashioned petunia cultivars, while pretty on store shelves, don’t perform as well in the heat as newer varieties bred for warmer, wetter conditions and that possess enhanced vigor and disease resistance. When shopping for petunias in the Panhandle, avoid anonymous petunia varieties of questionable quality and look for modern named hybrids, for example the Supertunia Series, the SuperCal series, and the Wave series. These improved hybrid petunias are resilient to pesky diseases like Botrytis Rot, flower heavily over a longer period, and tolerate temperature extremes better. Within these series, individual cultivars vary in flower color, flower size, and overall plant size (ranging from mounding monsters growing 4’ in diameter to tiny dwarfs that barely span 18”). I grew several varieties from each of these series this year and all performed wonderfully. There’s a petunia variety for every garden!

Once you’ve picked a quality cultivar, petunias are relatively easy to grow! In the Panhandle, petunias are grown as cool season annuals – planted in the fall (October-November) and grown through about May, finally playing out once the summer heat arrives. Petunias prefer full sun and are at home in containers filled with a quality potting mix (container size will vary from medium to large depending on the growth habit and mature size of the petunia). Petunias are not particularly drought tolerant and prefer regular water and fertilizer to look their best. I water my containers each day during sunny and warm conditions, backing off to every other day or less during cooler, cloudy weather. Because of their floriferous nature, petunias are also relatively heavy feeders and appreciate supplemental fertilizer. I top dress petunia containers with Osmocote or similar slow-release fertilizer at planting and supplement with liquid fertilizer every week to ten days during the peak of the flowering season.

Though it’s past petunia planting time this season, be on the lookout for petunias to hit nursery shelves next fall. Simply pick a good hybrid cultivar, plant in a container in full sun, water and fertilize regularly, and you’ll be rewarded with no-fuss, months-long color until the summer heat finally draws the curtain on the show!
