Want to start a vegetable garden, but don’t know where to start? Are you seeing rectangular boxes popping up all over your neighbors’ yards and wondering why? Well, I am here to spread the news of raised-bed gardening!
Raised-bed gardening is a convenient way to grow vegetables without worrying about the quality of your soil. This is because you will be bringing in a high quality soil mix to your site. Vegetable plants need nitrogen, phosphorus, potassium, and many other nutrients to grow and mature properly. In many Florida Panhandle soils, we either have too much sand, too much clay, and nearly always, not enough organic matter. Organic matter results from the various stages of decay of anything that was alive. Think of it as the “glue” that holds the soil together, improves both soil moisture-holding capacity and drainage, and slowly releases nutrients that become available to the plant.

Although you could add nutrients and organic materials to your soil without building a raised bed, the walls of a raised bed will hold your soil in place, reduce erosion, and even help keep out weeds. Here are a few things to consider when planning the installation of a raised-bed garden:
Location
The most important thing to consider when picking your location is sunlight. Vegetable plants need a lot of direct sunlight for optimum production. Leafy vegetables (lettuce, kale, arugula) can tolerate four to five hours, but fruiting crops (tomatoes, squash, peppers) generally need six hours of full sunlight to grow strong and produce fruit.
When starting a garden, remember that we are in the northern hemisphere, and this means the sun dips to the south, especially in the winter. Objects therefore cast a shadow to the north, so pay attention to the position of southern tree lines, houses, and anything else that may block the sun. If you must choose, morning sun is better than afternoon sun, as afternoon sun can be very extreme in our area, especially in the summer.
Lastly, consider visibility! If you stick your garden in the very back corner of your yard, how often will you see it? The more visible it is in your daily life, the more likely you will notice easy-to-pull weeds, when your garden needs watering, what is ready to be harvested, and everything else that goes on in the garden.
Although wood is most popular, you can use materials such as concrete, bricks, or tiles to build a raised bed. Photo by Molly Jameson.
Materials
Now you have chosen a perfect garden location. What materials should you use to build your raised bed? Lumber is the most popular material. But you could use concrete blocks, bricks, tiles, or anything else that can support soil. You can make your beds as long as you like, but the important thing to remember is not to make the raised bed wider than four feet. This will allow you to reach all areas of your soil without stepping into the bed, which causes compaction. If you are working with kids, two or three feet wide is even better. You should make the height of your bed 10 to 12 inches, which will allow good drainage and enough space for your vegetable plants to develop strong roots.
When choosing lumber, you can go with untreated or treated wood. Within the last 15 years, wood preservatives considered unsuitable for raised-bed gardening have been phased out. There is well-documented research that has shown the newer products are considered safe for gardening. Although untreated wood typically will not last as long as treated, even treated wood will still begin to decompose after a few seasons. Either way, connect your wood with lag bolts, instead of nails, to hold the wood together tightly.
When filling a four ft. by eight ft. raised bed, you will need about 1 cubic yard of soil mix. Photo by Molly Jameson.
Soil
Now that you have your raised-bed structure built, what will you put in it? There are many landscape and nursery companies that can offer vegetable garden soil mixes for purchase in bulk. Typically, they will be about 50 percent compost (organic matter) and 50 percent top soil (nutrient-containing minerals). If you are filling a four foot by eight foot by 12 inch raised bed, you will need about one cubic yard of soil mix, which typically costs $30 to $60. This is about the volume of the back of a pick-up truck. If you do not have access to a truck, most companies will deliver in bulk for a $30 to $50 fee. This could be worth it if you are filling up multiple beds! Seasonally, you will then need to top off your raised bed as your soil will shrink as the organic materials decompose. But for this, you can buy bagged soil mixes or make your own compost.
The last step is filling your raised bed with vegetable plants! This could also be considered the first step… as you now must consider plant spacing, spring vs. fall vegetables, seeding into the garden vs. using transplants, trellising, pest control, harvesting…but we’ll save all that for future articles. Happy gardening!

Wakulla Master Gardener Bill Osborne shows off some of the peppers he grew.
Vegetable gardening has many highly desirable benefits. These positive features range from being a good source of exercise, an opportunity to produce fresh produce which may be hard to find in retail establishment, and being able to assure it is produced in a specific way.
In many cases it is difficult, and sometimes tedious, to place an accurate assessment of the economic value on producing vegetables for home consumption. Household budgets in 21st century are problematic enough without literally bean (or some other vegetable) counting to measure profit or loss in the home garden.
As part of an effort involving UF/IFAS Wakulla County Extension Master Gardeners, some popular vegetable categories have had their production assessed. All were grown in the demonstration garden at the UF/IFAS Wakulla County Extension Office on Cedar Avenue in Crawfordville and Master Gardener Bill Osborne coordinated the project.
Several pepper cultivars and an heirloom squash cultivar was chosen to assess. They were selected based on their potential for producing over a long period of time during the summer months.
For the home gardener this means the potential for of eating fresh produce as it matures all season long. It minimized or eliminates the need for preservation expenses, which add to the cost of home production.
Each plant was grown under identical conditions in mushroom compost. The production would qualify as organically produced, but this was not part of the original assessment objective even though it would raise the end value of the useable vegetables.
The cost of the raised growing beds calculated out to approximately $15 per plant, but the expense could be spread over several years. This would reduce the annual expense to about $5.00 per plant for necessary growing inputs to establish the garden.
Values are always a tricky component to establish and necessitate certain assumptions. The prices used in this study were a composite of Big Bend area grocery store and super market prices. Each was rounded to the nearest quarter-dollar to keep calculations simple.
The results are reported on the chart included with this story. The big winner economically was the lemon squash with a retail squash prices averaged $2.25 per pound.
If consumed fresh, each lemon squash plant produced a $65.25 value with $5 of expense. The home gardener netted $60.25 saved in their food budget
Conventionally-grown specialty peppers averaged $4.50 per pound, with organic receiving a much higher price. The big economic winner was the Giant Marconi cultivar producing 10.5 pounds. When expenses were removed, the plant produced $42.25 of retail value.
Close behind was the Mesilla cultivar with 10.12 pounds of production. Its retail production value netted to $40.50 per plant.
While eating fresh vegetables is a healthy practice, successfully growing them can be a helpful practice for the family budget.

Being a gardener in the panhandle has its advantages. We’re able to grow a tremendous variety of vegetables on a year-round basis. However, in this climate, plant diseases, insects and weeds can often thrive. Usually, chemical measures are applied to thwart these pests. Some panhandle gardeners are now searching for techniques regarding a more natural form of gardening, known as organic. With fall garden planting just ahead, this may be an option for conventional vegetable gardeners looking for a challenge.

So, what is organic gardening? Well, that really depends on who you ask. A broad definition is gardening without the use of synthesized fertilizers and industrial pesticides. Fair warning, “organic” does not translate into easier physical gardening methods. Laborious weeding and amending of soil are big parts of this gardening philosophy. This begs the question, why give up these proven industrial nutrient and pest control practices? Answer: organic gardening enthusiasts are extremely health conscious with the belief that vigorous outdoor activity coupled with food free of industrial chemicals will lead to better nutrition and health.
As stated earlier, the main difference between conventional and organic gardening is the methods used in fertilization and pest control. In either gardening style, be sure to select a garden plot with well-drained soil, as this is key for any vegetable crop. Soil preparation is the most important step in the process. To have a successful organic operation, the garden will require abundant quantities of organic material, usually in the form of animal manures and compost or mixed organic fertilizer. These materials will ensure water and nutrient holding capacity. Organic matter also supports microbiological activity in the soil. This contributes additional nutrients for plant uptake. Organic fertilizers and conditioners work very slowly. The vegetable garden soil will need to be mixed and prepped at least three weeks ahead of planting.
Effective organic pest management begins with observing the correct planting times, selection of the proper plant variety and water scheduling. Selecting vegetable varieties with pest resistant characteristics should be considered. Crop rotation is also a must. Members of the same crop family should not be planted repeatedly in the same organic garden soil. Over watering can be an issue. Avoid soils from becoming too wet and water only during daylight hours.
For weed management, using hand tools to physically removing weeds is the only control method. As for insect management, planting native plants in the immediate landscape of the organic garden will help draw in beneficial insects that will feast on garden insect pests. The use of horticultural oil or neem oil is useful. However, please read the product label. Some brands of oils are not necessarily “organic”. Nematodes, which are microscopic worms that attack plant roots, are less likely an issue in organic gardens. High levels of organic matter in soil causes an inhospitable environment for nematodes. Organic disease management unfortunately offers little to no controls. Sanitation, planting resistant varieties and crop rotation are the only defense mechanisms. Sanitation refers to avoiding the introduction of potential diseased transplants. Disinfecting gardens tools will also help. Hydrogen peroxide, chlorine and household bleach are disinfecting chemicals allowed in organic gardening settings as these chemicals are used in organic production systems for sanitation. Staking and mulching are also ways to keep plants from diseases by avoiding contact with each other and the soil.
Organic gardening can be a challenge to manage, but better health and nutrition could be the reward. Please take the article recommendations into consideration when deciding on whether to plant an organic garden. For more information, contact your local county extension office.

When you don’t know what’s ailing your plant, ask an expert.
Many gardeners get stumped when a favorite plant of theirs comes down with a strange “something”. Many of these gardeners know about UF/IFAS Extension and call their local horticulture and agriculture agents for assistance in figuring out what’s going on. However, even these experts are often stumped by what they see. Fortunately, the agents have another layer of experts to fall back on. In addition to the resources in Gainesville, we have the Plant Disease Diagnostic Clinic, located at the North Florida Research Center in Quincy. Plant pathologists here can help determine what fungus, bacteria, virus, or viroid may be the problem.
Plant pathologists are basically plant doctors. They use all sorts of sophisticated techniques to determine what is the cause of a particular plant problem, from growing out fungal spores to examining DNA. Not only do these plant doctors tell us what the ailment is, they also provide recommended cures, or control options. They are also doing research to prevent different diseases from taking hold in our area and reduce the impact on our local growers.
Plant pathologist at work!
At a recent workshop in Quincy, we learned that plant pathology researchers are working on a fungus that affects watermelons, virus and bacteria that can wipe out a farmer’s tomato crop, and a virus that could impact our local roses. Working as a team of scientists, they study these pathogens in the lab and conduct controlled field experiments to figure out which techniques are most effective. Some of this research is leading to different methods and/or products that can help growers and gardeners alike keep their fields and landscapes healthy.
So, if your plants have problems, please contact your local Extension Office. If they don’t know the answer, then the network of scientists, including plant pathologists, in the UF/IFAS Extension family can be called on for backup to provide you with the best possible answer.
