A common site in the garden – multiple hoses pieced together. Be aware of galvanic corrosion! Credit: Tyler Jones, UF/IFAS.
It was the best of times, it was the worst of times. It was a nice day in the garden, but when you go to disconnect the hose, it is somehow stuck to the spigot, connector, or other hose. You go and get the pliers, but the hose just doesn’t budge. If this has happened to you, then you now know of the chemical reaction that can occur between aluminum and brass hose fittings. Hopefully, this is just two hoses stuck together, and you can cut them off and replace them with new ends. If the hose is connected to the spigot and won’t budge, you may want to contact a plumber before you create a bigger problem.
While knowing the name of this chemical reaction, galvanic corrosion, doesn’t help you while you curse these hose fittings, it is yet another scientific discovery in the garden. Galvanic corrosion occurs when two dissimilar metals are in electrical contact with each other in the presence of an electrolyte. The metals must be dissimilar in their electrochemical voltage. I know, you just want to disconnect hoses, not learn physics, but this stuff is interesting! Basically, aluminum is pretty reactive, especially when joined up with brass, bronze, copper, and even stainless steel. In the case of our hoses, the water acts as an electrolyte thanks to the calcium present in our delicious and abundant limestone aquifer groundwater. You put all these together and, bazinga, you have the aluminum hose end corroded into your brass hose end so strongly that no pliers will ever unlock them.
This won’t work out well for too long! Aluminum hose end on a brass spigot will lead to galvanic corrosion. Credit: Mark Tancig, UF/IFAS.
So, what do you do to prevent this? The easiest way to prevent galvanic corrosion from ruining your nice day in the garden is to only purchase products with the same material as your spigots. Brass spigots, hose bibs, and hose ends have been the industry standard, while aluminum hose endings seem to be more of a recent occurrence. Aluminum is cheaper, so you can understand why the hose companies would be interested in switching. If you already have two different materials, first check and see if you can get them disconnected. If not, start purchasing new hoses that match the spigot and/or connector. If you can get them disconnected, one method to prevent galvanic corrosion is to just disconnect them regularly to avoid them fusing. Not sure if you’ll remember? You can also use a plastic connector between the hoses to make sure the two metals don’t touch each other or switch out the aluminum hose ends with replacement brass or plastic ends, found at most hardware stores.
A quick fix is to place a plastic connector between the dissimilar metals. Credit: Mark Tancig, UF/IFAS.
Now that you’ve learned about galvanic corrosion, it’s time to get back to gardening. Good luck with those hoses! If you have other gardening questions, please contact your local extension office.

Another North Florida winter is here! With that comes a new plants from leafy greens to snapdragons. It also means the inevitable freeze is on the way. It is prudent for all gardeners to review what needs to be done to protect your non-freeze hardy plants.
Hardiness Zones
Before we get into what actions you may need to take, let’s examine plant hardiness zones. These are geographic areas created by the US Department of Agriculture defined by their average extreme minimal temperature. In the Panhandle these are zones 8b through 9b. In winter we will likely see low temps between 15 – 30 degrees depending on your zone. Sourcing plants appropriate for your zone can mitigate quite a bit of cold damage in your landscape. If you like plants susceptible to the cold, you can interplant them to add a little protection.
Microclimates
Find and utilize your yard’s microclimates. Areas under larger trees are likely to remain warmer in the winter. This is also true behind a windbreak, or near a structure with high sun exposure. Look around your yard and plant any cold sensitive plants in these areas.

Full Season Plant Care
Cold protection begins with warm season plant care. Pay close attention to the irrigation and fertilization needs of your landscape plants. Apply these properly to ensure stress free plants moving into the colder months as these will perform better as the mercury begins to drop.
Imminent Freeze Actions
Ok, now that everything is planned, we know our microclimates, and we’ve cared for our landscape through the year let’s see what can be done when a freeze is imminent.
Water the morning prior to a freeze event. Wet soils retain warmth better than dry. That heat will be re-radiated through the freezing night keeping your plant slightly warmer. Adding some mulch will aid this effort. Watering again the next day will break any ice formed in the soil. Keep in mind that prolonged saturation could be detrimental to root systems. Scout your plants regularly after using this strategy to ensure plant health.
Protect potted plants by bringing them indoors. Those that are too big to move should be padded with extra mulch, and clustered together when possible. Make sure to move them back in place when the warmth returns.
For those trees with graft points (i.e. Citrus), tree wraps may be used as protection. If you don’t have these, pile mulch around the base of the tree to insulate the graft. The idea here being that even if the branches above the graft succumb to the cold, the tree can rebranch above the graft thus keeping the desired fruit of that tree.
Finally, cover your plants. Covers are more useful for frost than freezing temps but are better than direct exposure to cold air. Keep these off the plant’s foliage while ensuring they reach all the way to the ground. Think ghosts over lollipops. Taking them to the ground will capture any heat radiated out of the soil overnight. The addition of lights underneath the cover can help keep that area a little warmer. Be very cautious when doing this as too much heat under the cover could be dangerous.

You may see some nurseries apply irrigation via sprinklers through the freeze as protection. While this method does work, it requires some specialty equipment. Additionally, you’ll need to apply the water prior to the freeze setting in and continue until the temps return. It not a practical solution for homeowners.
Once the cold passes, keep an eye on your plants. Wait until you see new growth before pruning damaged plant tissue. If in doubt you can slightly scrape the bark. If the cambium beneath the scrape is green, it is still alive.

When making plans for a fall or spring garden it is important to consider which methods of planting and raising your crops will work best for you. Traditional ground plots can be very effective but like with anything there can be negatives. Issues with space and soil fertility will be your biggest challenges with ground plots. Raised Beds are a very popular choice for several reasons like being aesthetically pleasing, mitigation of poor or no soil, decreases runoff/erosion, positive use of space, and maintenance.
Site Selection – Before creating your raised bed there should be a couple of key factors that are considered. Sunlight is the most important factor. Areas where the raised beds are constructed must have full sun for a minimum of 5 to 6 hours per day for best results. It is ideal to have morning sun do it less intense heat in the morning and dries due off the plant. Staying clear of structures, large trees, tree lines will help to have ample sunlight. Access to a water source close by is imperative for a successful raised bed. Make sure it is placed on well drained level ground away from tree roots that could compete with your crops.
Construction – The most “traditional” raised bed structure are made with wood. Consider pressure treated vs. non-treated wood. Pressure treated wood post 2004 is unlikely to contaminate food crops and will have a longer shelf life. Non-pressure treated will be a less up-front cost but will end up costing more overtime due to having to replace the boards earlier and more often. Screws and nails are appropriate methods to secure the corner but be sure to dispose of them correctly. Concrete corner blocks found at stores like Lowes or Home Depot have become a popular mothed to secure the corners. A 4’x8’ bed is the most popular size due to easy maintenance and construction. To construct this sized bed all you will need is three 2”x6”x8’ boards and four concrete corner blocks. After the outline of the bed has been created, you will need to create a base layer to kill the grass below, so it does not grow up through the soil. You can use materials like cardboard or mulch to accomplish this. The raised beds should be filled with either a mix made for raised beds or a 50-50 mix of compost/organic matter and topsoil. 1 cubic yard of material will fill a 4’x8’ raised bed.
Raised beds can be an effective and fun way to garden at home. Consider all factors discussed to make sure your raised beds are successful. For more information on raised beds contact your local UF/IFAS Extension Office.

Planning landscaping is undoubtedly not easy. The primary concern relegated to each individual homeowner is what you want out of your yard. Many are content with just grass, while others desire a diverse array of plant life. One aspect oft overlooked is your landscape’s capacity to be a boon for local wildlife. With a bit of planning, your property could be literally buzzing with insect pollinators, wild birds, and even our reptilian friends.
Where to Start
For this article, let’s begin with a newly established development. What has happened in this scenario from an ecological perspective, with what we’d call primary succession? In short, this means an area that experienced a complete reset of its plant communities. In nature, this would be the result of events such as a volcanic eruption, but in Florida, it’s far more likely due to bulldozers.
Now, the good news in this scenario is that you won’t be receiving your property in this condition. The developer has fast-tracked the process by planting grasses and some basic trees by the time you’ve purchased the property. It’s from this basic setup that you, my new homeowning friends, can begin your husbandry of our local animals.
Begin by investigating the where your new home was built. If it began as a wetland, you’ll want to select plants appropriate for that environment. The same is true if you’ve moved into what was forest land. This thought aligns directly with the first of our FL Friendly Landscaping principles: right plant, right place. There is little sense in putting plants that don’t like wet feet into a poorly draining soils common in wetlands.

Consider Your Environment
You’ll also want to investigate the wildlife that is endemic to those environments and areas. Knowing what is there, and what you’d like to attract to your landscape, will help you decide which plants will be best. For instance, replacing a crape myrtle (Lagerstroemia indica) with a red maple (Acer rubrum) in what was previously a wetland environment puts a tree better suited to that environment, which will require less maintenance from the homeowner. Additionally, red maples are known to be an early-season nectar source for a multitude of moths and butterflies while providing nesting sites for local birds.
Red maples are a great example of plant selection and what it can do to attract wildlife to your yard, but there are other guidelines with which you’ll want to be familiar should this be your goal.
Guidelines for Attracting Wildlife
Water is critical to all life on the planet, including wildlife. Providing water features in your garden will increase the chance for animals visits to your garden. This can be as basic or as elaborate as you’d like. Everything from a pond to a simple dish of water will suffice. One common water feature challenge to consider for Florida gardeners are mosquitos. Avoiding these pesky creatures could be as easy as creating flowing water features. Solar fountains are an easy and cheap way to accomplish that goal.
Shelter is another critical aspect to attract wildlife. Either natural or man-made, it is essential to attracting and keeping various species in your yard. Bird, bat, or owl houses are perfect solutions to this issue. Just ensure you site them correctly to provide the correct environment for the animal in question.
Design your landscape to be layered. In this instance, this means integrating shrubs, trees, herbaceous plants, and groundcover. Doing so will provide some cover for feeding while providing visual interest to your home.
Last and certainly not least, choose plants known to be a food source. When doing so, you’ll want to research how those animals you’d like to attract eat. For instance, hummingbirds (Trochilidae) have a small, curved beak. If this is the species you’d like, you’ll want to select plants rich in nectar with tubular flowers. Firebush (Hamelia patens) is an excellent example of a plant for this purpose.

Conclusion
Bringing local wildlife into your yard is an excellent way to get to know the small creatures living in your area. A few simple changes may go a long way toward reintroducing habitat to an area where it may be waning.

Peanuts, also known as groundnuts, earthnuts or goobers have a long history of cultivation. Unlike tree nuts, peanuts are grown underground which is how they earned the nicknames groundnut or earthnut. Originally native to South America, peanuts made their way to North America from Africa, where they were introduced by African slaves in the early 1800’s.

First grown in Virginia, peanuts were grown mainly for oil, food, and as a cocoa substitute. During this time, they were regarded as food for livestock and the poor. It wasn’t until the late 1800’s did their demand increase as there was a need for an affordable, high-protein food during the Civil War and World Wars. Their popularity also increased when showman, P.T. Barnum began selling hot roasted peanuts at his traveling circuses.
In the 1900’s, peanuts became a significant agricultural crop when the cotton boll weevil threatened the South’s cotton crop. Through the research findings and suggestions of Dr. George Washington Carver, peanuts were grown as a successful cash crop and contributed greatly to the sustainability of the farm. Though Dr. Carver did not invent peanut butter, he did invent more than 300 new uses for the peanut and peanut byproducts including shaving cream, leather dye, coffee, ink and shoe polish.

Today, peanuts are grown in 13 states, across the United States and the U.S. is the third largest producer of peanuts in the world. In 2024, Florida harvested 157,000 acres of peanuts, averaging about 3,500 pounds per acre with a production value of roughly $149.5 million (Annual Crop Production 01/10/2025).
Peanut Fun Facts:
- 99% of peanut farms are family-owned, businesses averaging 200 acres
- There are four different types of peanuts – Runner, Valencia, Spanish and Virginia
- Peanut plants are legumes and fix beneficial nitrogen back into the soil
- Peanut butter is an excellent source of niacin, and a good source of vitamin E and magnesium
- Peanuts do not contain cholesterol and are low in saturated fat
- Peanut butter accounts for half of all peanuts eaten in the U.S.
- It takes about 540 peanuts to make a 12-ounce jar of peanut butter
- There are enough peanuts in one acre to make 35,000 peanut butter and jelly sandwiches
- The average person will eat almost 3,000 peanut butter and jelly sandwiches in their lifetime
- Women and children prefer creamy peanut butter, while most men opt for chunky
- Peanut allergies affect about 1.8% of U.S. children and 1.1% of adults the U.S. population

While planning my fall garden I have been partaking in one of my favorite pastimes—shopping for seeds. This is always more fun to me than planting the seeds. Seeds come in many different packages and just like wine, you can be drawn in just from the carefully crafted label. Many of the seed labels I encountered shared the same marketing phrase, “non-GMO seeds”, which is like seeing a gluten free label on your pineapple. It was never an option!
Genetically engineered plants take decade(s) to produce, test and release. They are expensive and are not typically sold in small quantities. These patented seeds will not be sold to you by accident. GMO crops that are grown and sold in the US on a commercial scale include alfalfa, apple (Arctic), canola, corn, cotton, eggplant, papaya, pineapple (pink), potato, soybean, squash, sugarbeet, and sugarcane. More information about each crop here: https://www.ams.usda.gov/rules-regulations/be/bioengineered-foods-list
Recently, a few GE seeds have been developed for the home gardener.
The Firefly Petunia glows in the dark thanks to the insertion of genes from a bioluminescent mushroom. More info
The Purple Tomato has purple skin and purple flesh thanks to the insertion of snapdragon genes. This is the first genetically engineered food crop developed for the home gardener. More info
These seeds are only available from certain retailers, and you will pay a premium for this technology.
When purchasing seeds consider other factors like season and variety. “Right plant, right place” – you hear us say those four words again and again here at the Extension Office. That’s because plant selection is one of the most important things to consider for gardening success. If you were to start a watermelon from seed right now it may do well at first. However, they thrive in the heat of the summer, and they will not like the short, cool fall days. A plant growing in the wrong environment will be stressed. That stress attracts pests and can make a plant more susceptible to pathogens.
Set yourself up for success by growing plants when they are in season. Don’t be tempted by the seeds you see on the aisle end caps. These are not always specific to each region and just because they are selling it now does not mean it should be grown right now. Decide what you are going to grow before you go to the store! The Florida Panhandle Planting Guide is a great resource to use for planning your garden. If you find that you purchased seeds for the wrong season save them for the next one—and consider that your newest hobby may be seed collecting.
