Ants can be treated with spinosad in vegetable gardens. Photo by Molly Jameson.
There’s nothing worse than sinking your fingers into your garden soil to dig up a potato, plant a seedling, or pull up a radish, and be met with a sharp, painful sting, and little red critters rocketing up your arms. If you are a gardener in the panhandle, my bet is that you know exactly to what I refer: fire ants!
Fire ants are certainly not native to our area. These guys are an invasive species from South America that are very resilient, and many are territorial, with the potential to drive out any native ant populations. Fire ants arrived in the 1930s, and can now be found throughout most of the southeastern United States.
So when you end up with fire ant mounds engulfing your carrot patch, what can be done? Since fire ants in your garden mean fire ants in your food, the least toxic control methods are of high importance and conventional broadcast bait treatments and mound treatments should be avoided. Even in your lawn, be careful when using strong insecticidal bait treatments, as these can harm the native ant populations that help control the spread of fire ants. This can then lead to a strong resurgence of fire ant populations that can outcompete the native ants.
Although completely controlling fire ants in an area is not possible, there are sustainable management techniques that can help. Some fire ant colonies have a single queen while others have multiple queens. Either way, in order to eliminate a fire ant colony, all queens in the colony must be killed. Fire ants are omnivorous, in that they eat plants, insects, sugars, and oils. The catch is that they are only able to ingest liquids, so solid food must be brought into the colony, where larvae regurgitate digestive enzymes onto the food, breaking it down into liquids. Therefore, any method of control by ingestion will need to be in liquid form, or the ants must be able to bring the material into the colony, without first being exterminated.

There are some commercially available products that contain boric acid or diatomaceous earth. These products may reduce populations, but eliminating whole colonies with these products can be a challenge.
The use of a nervous system toxin called spinosad is effective on fire ant populations and is considered safe to use in vegetable gardens. This toxin comes from a bacterial fermentation process, and is therefore considered organic. But be aware, even though there are organic products with ingredients derived from botanical sources such as rotenone and nicotine sulfate, they should not be used in vegetable gardens. When using chemical methods of control, always follow the directions on the label carefully.
One physical method of control is the use of hot water. Three gallons of scalding water, which is between 190 to 212ºF, has been used on colonies with a success rate of 20 to 60 percent, when applied in several treatments. You will want to slowly pour the water on the colony, being extra careful not to get burned, and avoid injuring any surrounding plants. If you are like I am, and you often leave your garden hose in the hot sun, you can spray the ant colonies with the hot water, as you wait for the water to cool off enough to water the garden. Hot water control takes persistence, but you can eventually drive the ants out.
Another method of physical control is excavation. This requires digging up the mound, putting it in a bucket, and taking it to another location. Apply talcum or baby powder to your shovel handle and bucket to help prevent the ants from escaping and crawling up to sting you.
One reason fire ants are so rampant in the United States is that they have little competition or natural enemies. Scientists have released multiple species of phorid flies, natural parasites of fire ants in South America, and a few species have become established. Scientists at UF/IFAS are currently researching additional fire ant biological control methods, such as the use of a fungi, which has shown promise.
Remember, not all ants in the garden are bad guys! Many species act as roto-tillers, aerating and redistributing nutrients in the soil. They also play a role as decomposers as they assist in turning dead insects into soil nutrients. Ants can disturb garden pests by attacking them or interrupting their feeding, mating, and egg laying processes. Additionally, ants are a food source for wildlife, such as other insects, frogs, lizards, birds, spiders, and even some mammals.

When you think of farmers’ markets, what is that comes to mind? Is it the customers perusing the tables, the vendors organizing their displays, the variety of colors of the fruits and vegetables, the aromas of many types of baked breads, the pop-up tents forming a loose circle…? Or is it all of these things wrapped up in a sense of community?

If you have not experienced a farmers’ market that evokes such senses, then you should stop by one of the farmers’ markets where vendors selling the produce actually grew it themselves. These markets are often referred to as growers’ markets.
Still not convinced? What is it that you are looking for? Liven up your summer dinner table with fresh blueberries grown in Monticello, sweet corn that hardly needs cooking, flavorful heirloom tomatoes, freshly dug potatoes, lime-green field peas, cucumbers with a crunch, sweet yellow onions, multi-colored oblong peppers, juicy garlic, yellow crook-neck squash, dark green zucchini, shitake mushrooms harvested off oak logs, herbs just picked that morning, edible flowers….
The adjectives used to describe the produce may seem like an exaggeration until you really dive into these flavors and learn about how they were grown, where they were grown, and why the farmer decided to concentrate his or her efforts on the particular varieties. And when you are at a growers’ market, don’t be shy! Ask the farmers what they are growing and the methods they use for farming. What has gone well, what has not. They very well may tell you it’s all in building the soil, conserving the water, and supporting diversity.

And don’t just come for the produce. At many growers’ markets, there are so many types of fresh-baked breads and cookies, local wildflower honey, local eggs, grass-fed meats, fruit preserves, hand-made soaps, and dried vegetables and powders.
Some growers’ markets in the Tallahassee area include the Lake Ella Growers’ Market, the Red Hills Online Market, the Frenchtown Heritage Marketplace, and the Sunshine Growers’ Market. If you do not live in the Tallahassee area, visit the Florida Department of Agriculture and Consumer Services Community Farmers Markets locator to find farmers’ markets near you. Take some time to explore your farmers’ markets to see who is growing their own and what markets are growers’ markets. In this way, you can help support local farmers!

Blueberries beginning to ripen at Blue Sky Berry Farm. Photo by Molly Jameson.
There is something almost magical about picking vibrantly blue blueberries off a bush and eating them fresh. If you watch the blueberries develop, you see them go from shades of pale green and blush red to dark and puffy and bright blue. When a blueberry is ready – you know it!
Blueberries are one of the few crop plants that are actually native to eastern North America. The most popular types are the rabbiteye blueberry (Vaccinium ashei) and the highbush blueberry (Vaccinium corymbosum). Both can be found in northern Florida and southern Georgia, and the highbush blueberry can be found as far north as southeastern Canada. There are at least eight other Vaccinium wild blueberry species that can be found in the woods and near swamps in Florida. They are usually smaller and don’t taste quite as sweet as the rabbiteye and highbush, but birds rely on them heavily for forage.
If you’ve never experienced a fresh blueberry right off the bush, then you may want to consider either foraging for wild blueberries, growing your own, or scouting out a local u-pick blueberry farm near you.

Let’s first consider the joys of growing your own. Blueberries require an acidic soil pH, between about 4.0 and 5.5. Lucky for most of us in the Panhandle, our soil pH is largely naturally acidic. If you have pine trees growing in your area, you most likely can grow blueberries. And the pine straw makes an excellent blueberry mulch! There are many rabbiteye cultivars that have been specifically developed to grow well in our hot climate – requiring fewer “chilling hours” than their northern counterparts. Check out varieties such as Powderblue, Brightwell, Tifblue, and Climax. Highbush blueberries can also do well in northern Florida, although they tend to flower early, making them susceptible to late freezes. Try highbush varieties such as Bluecrisp, Emerald, and Star. Each has its own advantages and drawbacks, such as fruit cracking and insect susceptibility. Click here to learn more about growing blueberries in Florida.
If you are not already growing blueberries, and you want fresh blueberries, then be sure to check out a local u-pick near you. This year you may have noticed we had a warm winter, which delayed the onset of blueberry dormancy. This means the crop is hitting its peak about two or three weeks later than normal. But don’t delay – blueberry season in north Florida typically declines by the beginning of July, so the season is upon us!
If you are in the east Panhandle, be sure to check out u-pick operations such as Blue Sky Berry Farm, Myrtle Creek Farm, Green Meadows Farm, and Blueberry Springs Farm.
Blue Sky Berry Farm, which is located just three miles south of the courthouse in Monticello, on 1180 Ashville Highway, is entering its second season as a u-pick, and its bushes have really grown! They use organic fertilizer and grow using sustainable farming methods. Blue Sky Berry Farm anticipates being open Saturdays and Sundays from 8 a.m. to 1 p.m. this summer, but anyone interested in picking blueberries should first check the Blue Sky Berry Farm website (http://www.bskyfarm.com), as it is updated regularly during the season.

Green Meadows Farm, located at 177 East Bluebird Road in Monticello, is five acres of USDA certified organic blueberries. The farm is located among the trees and has been designated a Certified Wildlife Habitat by the National Wildlife Federation. It is open Fridays and Saturdays from 7:30 a.m. to noon and 5:00 p.m. to dusk, and Tuesdays from 7:30 a.m. to noon, while the blueberries last.
Myrtle Creek Farm, located at 2184 Tram Road in Monticello, has beautiful blueberry fields that are dappled with shade in the late afternoon and early evening. They currently have u-pick blueberries and blackberries available. They are open during the weekdays and weekends while the blueberries last, but do call ahead (850-997-0533) to check on availability.
Blueberry Springs Farm is located at 383 Wacissa Springs Road in Monticello, and is celebrating their 25th anniversary of harvesting blueberries. They first planted in December of 1991 and had their first harvest in June of 1991. They are open Tuesdays through Sundays 7:00 a.m. to noon and 5:00 p.m. to 7:00 p.m. You can contact Blueberry Springs Farm at (850) 997-1238 for updates, pricing, and directions.
Also check out the Florida Blueberry Growers Association website and the Florida Department of Agriculture and Consumer Services u-pick locator to discover u-picks around the state, including grape and blackberry u-picks.
Whether you are foraging for wild blueberries, picking your own blueberries, or visiting a u-pick, be sure to bring along plenty of water, a hat, close-toed shoes, and sunscreen, as blueberry season can be a very hot and sunny time of year! But once you’ve experienced your first taste of hand-picked Florida blueberries, you will be hooked and coming back for more each and every summer!

Interested in having a garden, but have limited space? Maybe you live in an apartment, have poor soil quality, or you just don’t have many areas that get enough sunlight. Maybe you’ve tried gardening, but given up, labeling yourself as one of those who “just doesn’t have a green thumb.” Well, I’m here to tell you, don’t give up! Try container gardening. Growing your own vegetables in containers is easy and can be a very rewarding experience. Container gardens also tend to have fewer weed, pest, and disease problems then regular in-ground gardens. Following just a few guidelines, you can have a bountiful harvest of fresh fruits, vegetables, and herbs right by your front (or back) door-step!

So, what are these guidelines, you ask? Well, you first want to choose the right container. This could be a large flowerpot, window box, planter, 5-gallon bucket, half-barrel, recycled material…the list can be endless. Just as long as your container is big enough and has proper drainage. Generally, the container should be at least 10 inches wide and 10 inches deep. The bigger the better, as it will give the roots more space to grow, and the soil will not dry out as fast. Tomatoes, for instance, do best in larger pots, preferably the size of a five-gallon bucket. For many herbs, you can get away with planting two or three different types in the same container. It is also important that your container has drainage holes, so water can escape and air can circulate. Use a one-fourth inch drill bit to create holes in the bottom or along the sides near the bottom of the container if it does not have holes.
Most of us know plants need both sunlight and soil. But just how much sunlight and what type of soil? If you are growing vegetables, it is best to have full sun – which means at least six hours of direct sunlight per day. An advantage of growing in containers is that you can easily place a container in an area of your yard or on a balcony that receives adequate sunlight, when it would be much more difficult to build a garden in these same areas.

So what about soil? When growing in containers, you want to make sure you get potting soil that is made for containers. These mixes will contain materials such as peat, perlite, and vermiculite for both good drainage and moisture-holding capacity, and materials such as compost and nutrient amendments that will keep your plants healthy. You can simply ask your nursery specialist for a mix formulated to grow vegetables in large outdoor containers. If you are growing a lot of vegetables, you can cut down on costs by making your own mix. Just make sure you have a good balance of the aforementioned materials, and mix in a slow-release vegetable fertilizer, following directions on the label.
Now that you have your container, your soil, and a sunny location, it is time to get the plants. Some plants are best bought as transplants or grown from seed started indoors. Vegetables such as broccoli, collards, kale, tomatoes, eggplant, peppers, and strawberries fall into this category. Other plants, such as root crops, arugula, lettuce, spinach, mustards, beans, peas, cucumbers, squash, okra, cilantro, and basil can be started from seed directly into containers.
For some vegetables, buy transplants from your local nursery. Photo by Molly Jameson.
Okay, so you have all the materials. Now what? If you are growing from transplants, first thoroughly moisten the potting mix and the plant’s soil. “Transplant shock” is reduced when there is proper moisture. Set plants at about the same level they were growing in their original pot. For tomatoes, remove lower leaves and plant deeper in the container. If you are growing from seed, simply plant the seeds according to their label. A good rule of thumb is to plant the seed to a depth of about two to three times the seed’s diameter. If you are worried about your seeds not germinating, go ahead and plant more seeds than you need. But remember to thin to appropriate spacing if they do, indeed, all come up. Spacing will be specific to the type of vegetable.
After planting, water gently but thoroughly. Monitor your container garden, making sure the potting mix does not dry out. You can reduce evaporation by mulching with leaf litter, straw, or a similar material. Plants that grow tall or produce vines, such as tomatoes and cucumbers, will need support. A wire cage or pole, inserted into the container at planting time, will support the plant as it grows.
Last step is to call over all your friends and family and show off your beautiful vegetable plants! They will surely be impressed by your “green thumb” and will be eager to learn your gardening secrets.
