Potato: A Lot of Tuber in a Little Space

Potato: A Lot of Tuber in a Little Space

Looking to add a nutritional powerhouse to your early season garden this year? One plant that is often thought to be difficult to grow in Florida will surprise many home gardeners. This plant has a long, storied history, having been introduced extensively worldwide, and has invigorated and decimated entire populations. I speak, of course, of the humble potato (Solanum tuberosum), which performs well in our cooler North Florida winter. This member of the Solanaceae or nightshade family can trace its origins to the Andes mountains, where it was discovered by European settlers and brought back to their countries of origin. From there, the potato found success as a food crop and was reintroduced worldwide. This tuber is a big producer, and worthy of a spot in your home garden.

Varieties

The first objective with potatoes is to find a variety that will perform well in our sandy soils and climate. Russets are thought to be the gold standard in potatoes, and while some may be suitable, they are not optimal for Florida gardens. Instead look for some of the later entrants to this market. Several white and red varieties are available which mature quickly and can tolerate environmental conditions in the panhandle. White varieties suitable for this region are ‘Lachipper’ and ‘Sebago’, while the red varieties known to do well here are ‘Red Lasoda’ and ‘LaRouge’. These are compatible with our environment and as such perform well here.

Growth Practices

A well-draining, slightly acidic, and loose soil will provide the best environment for maximum yield. As with all gardening, it’s best to have your soil tested well before you plant and make any pH adjustments required early. Potatoes grow from “seed” which are essentially smaller potatoes grown specifically to produce more plants. It’s best to acquire these from a reputable seller and avoid grocery store leftovers, as their variety and disease resistance is questionable. Growth happens from the “eye” of the seed, which may be planted with or without growing roots.  Cut the seeds into smaller pieces, ensuring there is at least one eye per piece, and allow them to sit in a cool, dark environment for a few days to callous over. They are now ready to plant and should be four inches deep, spaced eight inches apart in three-foot rows. Potatoes require two fertilizer applications, emphasizing nitrogen and potassium specifically, as these pass through the soil easily with irrigation. Apply half of the fertilizer at planting with another application approximately 30-40 days later. Application rates vary and are based on yield goals as well as soil test results so check with your local extension agent to discuss application rates. Keep the potatoes evenly moist but make sure not to flood the rows. Finally, there is a unique methodology with potatoes in that you’ll need to add soil to the top of the row when the potatoes poke through. This is called hilling and is crucial to keep the tubers from turning green and producing a toxin known as solanine.

Harvest Time

Your potatoes should be harvestable in about 90-105 days, depending on variety and environmental factors. You’ll be able to tell the plant has matured as the vines will begin to die back naturally. Modern practices have augmented this to include a vine kill which may be performed mechanically or through chemical application. This will force the tubers to mature, allowing the gardener greater control of harvest times and helping to avoid the risk of late-season pathogens. Vine kills are performed between 80-90 days after planting with tubers remaining in the ground for an additional 21 days. All of these time frames are dependent on variety but will produce a more usable and easy-to-store tuber.

Bird Feeder Surprises

Bird Feeder Surprises

Many homeowners enjoy placing bird feeders in the landscape and filling them with purchased bird seed mixes to delight in observing the various visitors. In addition to our common songbirds, and maybe some rare migrating species that stop for a moment, you may also find some non-feathered species, such as the ever-troubling squirrels and an occasional snake. You may find some interesting and new plants popping up under the feeder, too.

Plant volunteers under the feeder are usually coming in from the bird seed itself. Hulled seeds, as well as any imported seeds, are less likely to sprout, but bags of purchased bird seed will generally provide an ingredient list, showing you the potential options. Based on my observations, along with a review of other articles and communication with local bird seed providers, the common plants you will see sprout under the feeder include millets, safflower, and sunflowers.

Millet is a common name applied to various grain crops. Proso millet (Panicum miliaceum) and great millet (Sorghum bicolor), also known as sorghum or milo, are your most common millets in bird seed mixes. Proso millet is more preferred as bird seed since most birds tend to push aside the great millet. Lower cost bird seed products will often have the great millet, and this species will readily sprout under a feeder. In addition to feeding birds, the various millet crops are also used to feed humans throughout the world, with sorghum being the fifth most important cereal crop after rice, wheat, corn, and barley.

Safflower (Carthamus tinctorius) is a surprising find under the bird feeder. Credit: Adobe Stock.

Safflower (Carthamus tinctorius) is the bird feeder volunteer that sparked my interest in discovering the plants contained in bird seed. Safflower is readily gobbled up by Cardinals, Grosbeaks, Nuthatches, Finches, and Titmice. This daisy relative is native to the Mediterranean region and is one of human’s earliest cultivated crops used for dyes, seasoning (a substitute for saffron), oils, and, of course, bird seed.

A more common bird feeder volunteer are sunflowers (Helianthus annuus). There are many varieties of sunflowers that have been developed over the years. Bird enthusiasts mainly distinguish between black oil and striped sunflower seeds. These derive from either oil-producing varieties (black oil seeds) or what is known as confection sunflowers (striped seed). The oil-producing varieties were bred to produce sunflower oil and the seeds are generally smaller, have a higher oil content, and a thinner husk, all making them very attractive to a larger variety of birds. The confection sunflowers have larger seeds on larger heads and were bred to be easier for us humans to get into. For feeding birds, the confection varieties with the striped seed have a thicker husk and so are harder for many smaller birds to feed on. If you allow these to grow, both varieties can grow quite large, so be prepared.

In general, many bird enthusiasts will encourage you to clean these seeds up as they can attract unwanted wildlife, from unsavory birds, like Pigeons, Starlings, and Finches, to mice and raccoons. However, even a tidy feeder of birds will likely have some seeds germinate and may want to know what they are. It’s also great fun to watch the birds skip your feeder and go right to the source, picking millet or sunflower seeds right off the plant.

While bird feeders should be considered a treat for your wild birds, like desserts on the top of the old food pyramid, they are still fun to set out in the landscape to provide a spot for you and your family and friends to observe wildlife. Remember that the best way to feed the birds is to provide a diverse landscape, especially one with many different vertical layers and native plant species. For more information on feeding birds, you can read the UF/IFAS document Attracting Backyard Birds: Bird Feeder Selection that contains information on the different types of bird feeders, but also on the various seeds.

Backyard Landscaping Tips to Support Birds This December

Backyard Landscaping Tips to Support Birds This December

NATURE’S NOMADS

Florida has a diverse array of birds. Warblers, raptors, shorebirds, and more may be spotted now in North Florida. Your yard or landscape can serve as an ideal habitat for wildlife, particularly birds. Even a modest quarter-acre plot can be intentionally designed to offer a supportive environment for a variety of birds. Transforming your backyard into a sanctuary for birds might allow you to witness these fascinating visitors firsthand.

CONSIDER NATIVE PLANTS

Bring a touch of local charm to your yard by choosing native plant species whenever you can. Native birds have a natural connection with these plants, having evolved alongside them. What’s more, landscapes featuring Florida-native plants demand less attention and resources compared to those with non-native varieties. Native plants are well-suited to the local soil conditions, usually need less fertilizer, and boast better resilience against common pests and diseases. Embrace the beauty of native flora while making your yard a low-maintenance haven for both birds and nature.

MAKE SAFE COVER AVAILABLE

When trees face disease or reach the end of their life, think about leaving them as standing snags—imperfect yet invaluable shelters for wildlife to feed and nest. Additionally, creating a couple brush piles, especially near other plants, offers fantastic cover and feeding spots for birds. These piles not only provide a feeding opportunity for our feathered friends but also act as protective hideouts in open spaces. Embrace the natural cycle by turning aging trees and brush into welcoming havens for local wildlife.

INCLUDE A VARIETY OF LAYERS

Birds take to the skies, and for a thriving habitat, it’s essential to have various levels in your environment—tall trees, medium-sized trees, high and low shrubs, and groundcover. The more diversity, the better, as different bird species rely on different layers for their needs.

Tall trees play a crucial role, creating a sort of continuous woodland environment where birds can gracefully move from tree to tree. The choice of trees and shrubs you plant significantly influences the overall health of your landscape. Opt for species that suit your specific site and soil conditions to ensure a welcoming and supportive environment for our avian friends

ADD A WATER SOURCE

Water is a vital ingredient for wildlife environments, and birds reap the rewards from any water source you offer. It can be as easy as placing a shallow dish or bowl filled with water or adding a small fountain to your outdoor space. Just remember to switch out the water regularly to thwart mosquito breeding and ensure a clean and refreshing oasis for our feathered companions.

UTILIZE BIRD FEEDERS

A delightful way to connect with nature and witness birds up close is by using bird feeders. Not only does this provide an opportunity for observation, but it also supplements the natural food sources available to birds near your garden. For those interested in incorporating bird feeders, it’s important to remember proper care and maintenance. Neglected feeders can become breeding grounds for mold and bacteria, posing a risk to the health of the birds. A recommended practice is to clean feeders at least once every 1-2 weeks, or more frequently in wet or humid conditions, using a diluted bleach solution. For nectar feeders, a simple wash with soap and hot water is sufficient. Always ensure the feeders are thoroughly dry before refilling them with bird feed. This way, you not only create a welcoming space for our feathered friends but also ensure their well-being through responsible feeder care.

WINTER WANDERERS

Creating a bird-friendly backyard in North Florida is not only a satisfying project but also a meaningful way to help protect our feathered friends. By making smart choices in your landscaping, you can turn your outdoor space into a welcoming sanctuary for birds. The benefits are twofold: you get to enjoy the colorful variety of bird species visiting your backyard while also contributing to the conservation of biodiversity in the area. Let your backyard showcase the harmonious relationship between humans and nature’s nomads. For tips on landscaping that supports birds, reach out to your local county extensions office.

Chinese Cabbage Becoming Increasingly Popular in Panhandle Gardens

Chinese Cabbage Becoming Increasingly Popular in Panhandle Gardens

Looking for a mid-season vegetable to plant in your garden? Look no further, Chinese cabbage is a great option. This cabbage matures quickly and is ideal for growing in winter’s shorter days and cooler temperatures.

Growing Asian vegetable crops in Florida has become an increasing trend over the last decade, mostly due to health benefits and profitability by producers. However, the crop is new to many, who are interested in growing and consuming these vegetables. There are two sub-species of Chinese cabbage. The Pe-Tsai group are the broad leaved, compact heading varieties. The head may be six inches across and either round or cylindrical, in shape. The second group is known as Bok Choy (figure). These are non-heading Chinese cabbage varieties that have several thick, white leaf stalks, and smooth glossy, dark green leaf blades clustered together, similar to the way celery grows.

Again, cooler temperatures are key. Warm temps cause the plant to uptake more calcium, making the heads soft and bitter and may contribute to early seed development through bolting. Chinese cabbage matures in around forty to seventy-five days from planting, depending on variety. There’s no specific requirements to growing this cabbage in Florida, just follow the same soil preparation, liming, fertilization, and cultivation practices that you would use for other leafy vegetable garden crops. The main pests and diseases that occur are leaf blight, downy mildew, aphids, and cabbage caterpillars. Leaf blight and downy mildew usually occur in warmer times of the year, with higher temperatures and rain.

Chinese cabbage is very versatile. It’s great in salads, stir fry, pickled and even as a replacement for lettuce on your favorite sandwich. Enjoy!

For more information on Chinese cabbage, please contact your local county extension office.

Yaupon Holly

Yaupon Holly

For most of the year, yaupon (pronounced “yo-pon”) holly is the nondescript evergreen backdrop to forested areas throughout the Panhandle. But in the fall, these plants are bursting with brilliant red berries. There are 9 holly species native to our area, all with evergreen, mostly oval shaped leaves. Of these, yaupon is among those with the smallest leaves. Members of this species can be distinguished from the similarly sized myrtle-leaved holly by their leaf margins. While myrtle has smooth edges, yaupon has scalloped/serrated edges. Both species sport bright red berries, tasty only to birds and other wildlife.

The leaves, however, have historically been ingested by humans. I’ve tried homemade black yaupon tea, and it is quite tasty. Native Americans throughout the southeast brewed a “black drink” from yaupon holly as a natural stimulant and for use in ceremonies. It is one of just a handful of naturally caffeinated plants that grow in the wilds of North America, and Spanish explorers quickly took up the habit as well. Lore says that overconsumption can lead to stomach ailments, hence the Latin name Ilex vomitoria. By most accounts, however, you’d have to drink gallons of the stuff to actually get sick. Rumors still circulate that this unappetizing misnomer was deliberate, because by the late 1700’s the homegrown American tea was starting to rival popularity of British teas. In addition to tea, Native Americans would use the plant medicinally and also convert the shrub’s typically straight branches into arrow shafts.

Early American settlers drank yaupon tea frequently when tea was hard to obtain from overseas during the Revolutionary and Civil Wars. During the rationing periods of World War II, the American government encouraged the substitution of yaupon tea for coffee and other teas. While it never really took off in the 1940’s, Texas currently has a rapidly growing industry in harvesting the plant. Growers are selling it as tea and as flavoring for a wide variety of food and drink products. To maintain a steady supply of leaves, tea makers often clear landowners’ property of overgrown yaupon shrubs, free of charge. This win-win solution provides an inexpensive harvest, reduces wildfire fuel, and allows native grasses and other open-canopy species to thrive.

For the most part, the plant is considered a nuisance in forested areas. It is one of those woody species that grows up quickly in areas that haven’t been maintained by fire on a regular basis. As a home landscape plant, it works well as an evergreen screen. While it can grow up to 20’ tall, yaupon responds well to routine pruning. Most native hollies thrive in both wet and dry soils, so they are truly versatile. They are also salt-tolerant, drought-tolerant, wind resistant, and provide winter color and food for wildlife in their bright red berries.
