It’s never too early to start thinking about your spring vegetable garden. Have you ever wondered how much it costs to grow your own vegetables? Does it cost less to grow your own vegetables or buy them from the grocery store or farmers market? A number of factors are involved with answering these questions and budgeting for your home garden.
Materials
The materials used are specific to your own vegetable garden. If you do everything by hand you may need a hoe, rake, and spade along with a number of other tools you can use from year to year. When budgeting for you garden you would need to think about the life expectancy of these tools. Let’s say a $20 rake lasts for 10 years. In that case, you would budget $2/year ($20 ÷ 10 years = $2/year) for the rake. This might also be the case with a bag of fertilizer. You may buy a 50 pound bag of fertilizer and use half the bag in year one and the other half in year two, so the cost of the fertilizer would be cut in half for your yearly budget. Other materials may be purchased for just one growing season such as pine straw for weed suppression or you may buy only enough seeds for the season.
Labor
A lot of work goes into growing your own vegetables. If you have the time and enjoy gardening then you may choose to charge yourself nothing for your work. However, from a cost analysis perspective you may want to put a value on your work. This will give you a better comparison to buying vegetables.
Budgets
Of course you could create your own budget based on all the costs that go into gardening. But why do that, when it’s already been done for you. The UF/IFAS Costs and Benefits of Vegetable Gardening publication includes a Microsoft Excel Cost Workbook to help answer some of these cost questions. This budget template is customizable, so it’s important that you consider all the costs for your vegetable garden. If you are looking for more detailed crop budgets, there are a lot of North Florida Enterprise Budgets available from UF/IFAS.

Trees provide shade, aesthetics, and perspective to the landscape. However, they only serve as burdens if not properly selected and maintained. To help determine what trees do best under certain conditions and to provide information on tree care, this month’s Gardening in the Panhandle LIVE! was all about trees.

Tree Selection
Some trees grow faster than others. That’s not always a good thing, but if you’re trying to select a tree that grows fast and will provide shade in your yard then you might want to give the following species a try. Click on the links for more information.
A lot of times you’ll read a particular tree species prefers moist, well-drained soil. Some coastal soils are very well drained and require supplemental irrigation after establishment to keep some species alive. One tree that does well in sandy, well-drained soils without supplemental irrigation is the sand live oak. Another tree, that would never win a popularity contest, but does well in sandy soils is the sand pine. This tree has a gnarly growth habit, which would make it an interesting focal point in the landscape. Turkey oaks are another option for dry spots.
There are a lot of fruit tree species that can be grown successfully in the panhandle. The key to good fruit production is selecting trees that are adapted to the average number of chill hours (usually calculated by the number of hours between 34ºF and 45ºF) your yard receives on a yearly basis. Some peaches, plums, and nectarines have been developed for our climate. Citrus such as satsumas and tangerine hybrids grow well in the panhandle, but sometimes require cold protection. Persimmons, loquats, and pears are other fruit trees that grow well.
If you already have mature trees in your yard, then you may be looking for smaller, understory trees to enhance your landscape.
Living this far south, you often have to really seek out trees that change color in the fall. Dogwoods, Florida maples, and blackgum trees all have great fall color. Some of the red oaks also have nice fall color. Two that come to mind are the nuttall oak and the Shumard oak.
Trees can cause a lot of damage if planted too close to sidewalks or buildings. To determine if a tree will fit in a confined space, you will need to consider its mature trunk flare diameter.
Florida is the southern extreme for growing ginko trees. If you decide to plant a ginko tree, make sure to select a male cultivar to avoid stinky, slippery fruit.
To successfully plant a tree, you need to start with a healthy tree. If the tree you purchase was grown in a pot, make sure it isn’t rootbound and doesn’t have encircling roots. You also should inspect the tree’s form, branching structure, and look for the presence of included bark. Please read “Selecting Quality Trees from the Nursery” for more tips on what to look out for when purchasing a healthy tree.
Some trees are more tolerant than others of high winds and flooding. Please read this publication about tree failure from hurricanes to help determine what tree species are better adapted to these weather events.

Tree Maintenance
Armillaria is a common fungal pathogen that infects trees from their roots. Other major diseases are more specific to certain species. A more comprehensive list of tree and shrub diseases can be found on the Ask IFAS website.
Tree establishment period depends on a lot of factors. Once a tree is established, it’s roots can be equal to about three times the distance from the trunk to the dripline.
Part of the beauty of a bald cypress is its knees. However they can also be a nuisance for mowing and other yard maintenance. The purpose of cypress knees is a bit of a mystery and there are a lot of theories on the subject.
Fallen leaves can help add nutrients back to your yard. Even if you are trying for a manicured lawn, you may want to rake up the leaves and use them elsewhere in the landscape.
Regardless of the species, most fruit trees benefit from a good pruning. Deciduous fruit trees should be pruned to maintain good branch structure and form, while citrus may benefit from a light hedging.
Trees are a wonderful addition to any landscape, but it’s important you select the right tree for the right place. Hopefully this article provided some information to guide you in the right direction.

Houseplants can soften up the interior of your home and help clean the air. They can also supplement your holiday decorations and help create stunning focal points. To help determine what plants do best under certain conditions and to give pointers on plant care, this month’s Gardening in the Panhandle LIVE! was all about houseplants.

Environmental Conditions for Houseplants
Unless you live in a glass house, you’ll probably want to choose houseplants that do well in low light conditions. A guide for what light level different houseplants prefer can be found on the Gardening Solutions Light for Houseplants page. This page also provides useful tips on supplemental lighting.
Some houseplants are better at cleaning the air than others. A list of houseplants that do a good job improving indoor air quality can be found on the Gardening Solutions Houseplants That Clean the Air page.
The best way to determine if your houseplants need water is your own green thumb or whatever finger you choose to stick in the potting mix, but for some interesting information on outdoor soil moisture meters check out this informative publication on soil moisture sensors.
Houseplants need a good quality, well-drained potting mix to thrive. Tips on selecting a potting mix can be found on the Gardening Solutions Container Media page.
Houseplant Pests
One of the best ways to rid houseplants of insect pests is to set the plants outside for a few days and let the pests move on. For some information on pest control products in and around the home check out the publication Natural Products for Managing Landscape and Garden Pests in Florida.
Fungus gnats are mainly a nuisance, but some species can feed on living plant tissue. Darkwinged fungus gnats are known to feed on ferns, orchids, and geraniums.
Houseplant Propagation
One way to increase your houseplant population and save a few dollars is to propagate your own plants. The University of Florida/IFAS created the Plant Propagation Glossary to help with any propagation questions you may have.
Air layering is a propagation technique that not only allows the prospective plant to thrive from the nutrients of the mother plant, but it also saves space.

Specific Species Info
Orchids in the genus Phalaenopsis are easier to care for than other genera of orchids. The American Orchid Society provides some great tips on caring for orchids indoors. Some people choose to water their orchids with ice cubes. The Ohio State University has a publication that provides some more insight on watering Phalaenopsis orchids with ice cubes.
A lot of cacti do well indoors. A popular cactus during the holiday season is Christmas cactus. Christmas cactus have interesting foliage, but their blooms are what people want to see. Some tips on getting your Christmas cactus to bloom on time and general care information can be found in this Christmas Cactus Preparation fact sheet.
Have you ever wanted to grow fruit trees indoors or do you want some tips on bringing containerized fruit trees indoors for the winter? The Growing Fruit Crops in Containers publication provides some good tips on growing fruit trees indoors.
Unless you have a house with a lot of windows or a sunroom, plumeria don’t make the best houseplants. They need at least six hours of sunlight per day and need to be at least three years old to bloom. If you are interested in propagating plumeria, then check out this publication on propagating plumeria from cuttings.

Invasive species are all around us, from invasive plants like cogongrass to invasive amphibians like Cuban tree frogs to invasive insects like red imported fire ants. These species affect our ecosystems by outcompeting native species for nutrients or food and other precious resources. To help with the management of these noxious organisms, the October 2021 edition of Gardening in the Panhandle LIVE educated the public on invasive species. The highlights from the webinar are listed below.

There seems to be a lot of interest in being sustainable and saving seeds is one way to be food sustainable. Should you save seeds from your garden? When it comes to peppers and a number of other vegetables in your garden…it depends.
Wakulla Master Gardener Bill Osborne shows off some of the peppers he grew.
Hybrid vs. Open-pollinated
If you plan to save seed from your peppers, you first need to determine whether you planted open pollinated or hybrid peppers. Hybrid varieties are produced from two distinct pepper varieties and are often designated by “F1” appearing after the variety name. The seed from hybrid varieties is not usually saved because it does not produce plants and fruit that are true to the original variety. Open-pollinated varieties are developed from inbreeding plants for multiple generations to develop a stable genetic make-up. Seeds saved from these varieties will produce plants and fruit that are true to type.
How to Save Seed
To save seed of a known variety, it is important to isolate flowers or plants to ensure cross pollination from other varieties does not occur. There are four common ways to isolate flower/plants.
- Isolate plants from pollinizer insects by growing them indoors or in a greenhouse.
- Cover individual plants with insect exclusion netting.
- Separate different varieties by at least 400 feet.
- Put a small bag over an emerging flower until it has self-pollinated. Then remove the bag for fruit development.
The options above will help ensure your plants produce seed true to type. A fun experiment would be to save seed from plants/fruit that are not isolated and planted near other pepper varieties. There are endless possibilities on the peppers your new varieties would produce and you may end up developing your own named cultivar. You could also choose one of the isolation techniques listed to selectively cross different pepper plants. One misconception about growing peppers is that hot peppers planted near sweet peppers will influence the flavor of the sweet peppers. As you may have gathered from the information about crossing varieties, the flavor of the next generation will be influenced by hot and sweet pepper being allowed to cross pollinate.

Harvesting and Processing Seed
Peppers should be allowed to mature before seed is harvested. In fact, germination rates are higher when peppers are allowed to dry for at least one month before seeds are harvested. Make sure that no mold or disease is on the peppers, because this could affect germination rates. To harvest the seeds, simply remove them from the pepper and remove any flesh from the pepper. If the seed was harvested from fresh peppers, rinse the seed thoroughly and allow to dry before placing in a sealable bag or container. If the peppers were allowed to dry before seed harvest, then the rinse step can probably be skipped. Store the seed in a cool, dark, and dry location such as a refrigerator.
