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!

Humans have used animal manures to fertilize food crops for thousands of years. Manures are an organic source of plant nutrients and are often a waste byproduct that must be properly managed when raising animals. Today, many farmers and backyard gardeners continue to use animal manures to provide nutrition to their crops. However, a recent experience at our local extension office brought to our attention the need to know what else, besides nutrients, is in the manure used.
A local backyard gardener brought in samples of tomato plants that had strange new growth. She had purchased the tomato plants, along with other vegetable plants, from a local nursery. When she repotted the tomato plants into larger pots, she added horse manure from her own horses to the soil mix. She then noticed this strange growth on the tomatoes, but not in the other vegetable plants that were repotted without adding horse manure. Herbicide damage was one of the first potential causes we suggested, since the new growth was twisted and distorted, a common symptom of plants that have been sprayed by herbicides. The gardener was sure she had not sprayed any herbicides near these plants, or in the pasture where she keeps her horses.

Photos of the tomato plants were shared with other NW District agents and an agriculture agent with livestock and hay producer experience had the probable answer – herbicide damage due to the horses being fed hay from a hayfield that was treated with a particular herbicide. Interestingly, this agent also had experience with these symptoms after their neighbor had similar issues using manure to fertilize the garden.
Herbicides with the active ingredients picloram or aminopyralid are able to cause this kind of unexpected damage to many gardeners’ crops. Herbicides containing these active ingredients are used in hayfields to control broadleaf weeds. These herbicides are especially effective at controlling hard to manage weeds such as thistle, nightshade, and nettle. They also provide long-lasting weed control. Unfortunately, the persistence of these ingredients extends into the hay, and also persists in the manure and urine of animals who eat hay from treated fields. These ingredients pass through the animal unchanged and remain active as an herbicide. Since many vegetable crops are broadleaf plants, the herbicide’s ingredients cause injury.
So what can a farmer or backyard gardener do to prevent this problem? When purchasing hay for livestock, ask the seller if they know whether the hayfield has been treated with herbicides that contain either picloram or aminopyralid. Most herbicides are known by their common names, rather than their chemical name. If they give you a common name or brand name, the active ingredient can be obtained by contacting your local extension office. If the seller can’t tell you, then, as a precaution, do not use the manure to fertilize broadleaf vegetable crops. The same question should be asked if purchasing hay for mulch as well. Composting the manure or hay does not break down the active ingredient, and may even concentrate it.
While we continue to use animal manures to fertilize our crops as our ancestors did, it’s important to remember that many of the tools and products we use today are much more advanced. These advanced products require that we stay informed of all precautions, use them responsibly, and, in this case, inform end users of any precautions. Remember to always read and follow the label and ask questions. And if a science-based answer is what you’re looking for, your local extension office is a good place to go!

Do you have a bare spot that you would like to see go away? How about a problem getting something to grow in a particular area? I’m not talking about that receding hairline or bald spot, I’m talking about your lawns and gardens. Many residents have these problems, whether it is too much shade under our beautiful oaks, that stubborn orange clay, or that hot, dry sand. Often times, the best remedy for these situations is to use mulch. Mulch is a versatile tool in the home landscape that provides many benefits while adding aesthetic beauty.
Some of the benefits of using mulch in your landscape include retaining soil moisture, reducing the amount of weeds, insulating the soil (keeps it warm during cold months and cool during the warm season), improving soil health through decomposition, and protecting plants from mower and/or trimmer damage. In addition, mulch can help protect the quality of local lakes and streams by reducing soil erosion and stormwater runoff. Therefore, not only can it improve your yard, but it can also help minimize impacts to our precious natural resources.
When purchasing mulch, there are many options available. Local lawn and garden shops offer many different types of mulch based on their origin (type of wood the mulch comes from), texture (shredded vs. nuggets), color, and, of course, cost. When considering these options, here is some information to help you choose:
- Origin. Cypress mulch comes from the harvesting of natural cypress wetlands and it not recommended by the University of Florida Florida-friendly Landscaping Program. Pine bark mulch is produced from the paper/pulp industry as a marketable byproduct. Pine needle mulch is harvested from pine tree farms as the trees mature to harvestable size.
- Plant Needs. Pine mulch (either bark or needles) can lower the pH of your soils as it breaks down over time. This is great for acid-loving plants such as azaleas, gardenias, and blueberries, but may affect species that require a high pH.
- Texture. The coarser the texture, the longer the mulch will last. Finely shredded mulches breakdown quicker than coarse mulches, such as bark nuggets. As the mulch breaks down, it adds organic content to your soil, thus improving soil health.
If you want to save money, you can often contact local tree trimming companies for their hard day’s work. As they trim or remove trees, the smaller material is shredded into mulch and they are often willing to drop it off in your yard instead of paying for its disposal. It is best to allow this freshly shredded mulch to cure for some time before placing it in your garden beds since freshly shredded mulch can temporarily reduce the availability of nitrogen in the soil.
When using free mulch options, be aware that weed seeds may be present.
Be sure to apply the mulch in a two to three inch layer in your landscape beds or around trees and shrubs. It’s not a bad idea to aerate any old mulch already present to prevent matting or compaction. This can be done with a rake or pitchfork.
So cover up that soil to improve the look and fertility of your landscapes and to reduce erosion and stormwater runoff. If you have any questions about mulch, more information is available at the Florida-Friendly Landscaping website: http://fyn.ifas.ufl.edu.

Magnolias are well known plants to gardeners and many are familiar with the foliage and flowers of these plants. If you are looking for another earlier bloomer, you may want to consider adding a specimen selection to your landscape, the Star magnolia (Magnolia stellata).
Although not native to the United States, star magnolia is a slower growing multi stemmed deciduous shrub reaching about 15 feet in height over time. The best feature are the bright whitish pink star-shaped blooms appearing in late winter before leaves emerge. The flowers offer gardeners a peek of the spring to come and remind us that our Gulf Coast winters are not that long. 
Plants do best in soil with some organic amendments and mulch over the root systems. A planting area that receives a little afternoon shade is ideal but established plants will adapt to sunnier locations when irrigation is provided during drier weather. Only occasional pruning is required to remove crossing branches or those that grow out of bounds. Prune after flowering if needed.

Though the calendar says December, the weather in Northwest Florida fluctuates between winter and spring temperatures. The nice days are wonderful opportunities to accomplish many of those outside landscape chores in preparation for spring. But, it is also a good time to start planning for next month’s colder temperatures. Since we don’t experience frozen soil, winter is the best time to transplant hardy trees and shrubs. Deciduous trees establish root systems more quickly while dormant; versus installing them in the spring with all their tender new leaves. Here are a few suggestions for tasks that can be performed this month:
- Plant shade trees, fruit trees, and evergreen shrubs.
- Plant pre-chilled daffodil and narcissus bulbs (late December/early January).
- Do major re-shaping of shade trees, if needed, during the winter dormancy.
- Water live Christmas trees as needed and water holiday plants such as poinsettias as needed.
- Check houseplants for insect pests such as scale, mealy bugs, fungus gnats, whitefly and spider mites.
- Continue to mulch leaves from the lawn. Shred excess leaves and add to planting beds or compost pile.
- Replenish finished compost and mulch in planting beds, preferably before the first freeze.
- Switch sprinkler systems to ‘Manual’ mode for the balance of winter.
- Water thoroughly before a hard freeze to reduce plants’ chances of damage.
- Water lawn and all other plants once every three weeks or so, if supplemental rainfall is less than one inch in a three week period.
- Fertilize pansies and other winter annuals as needed.
- Protect tender plants from hard freezes.
- Be sure to clean, sharpen and repair all your garden and lawn tools. Now is also the best time to clean and have your power mower, edger and trimmer serviced.
- Be sure the mower blade is sharpened and balanced as well.
- Provide food and water to the area’s wintering birds.

You’re digging up a ridiculously stubborn patch of Florida betony when an earthworm crawls across your path. As you break apart the soil in your hands a world of active organisms is being sifted through your fingers. Fertile soil is teeming with beneficial microbes. It is estimated that there can be billions of microbes in a single gram of soil.
Bacteria, fungi, and protozoa are major players in soil microbial processes. They perform a variety of functions beneficial to soil and the plants growing in that soil. Other soil organisms of importance are nematodes, arthropods, and earthworms.

Rather than being an inert material, soil houses a dynamic living ecosystem. Most soil organisms are too small to be seen, however they are still performing a great service to gardeners in many ways. These organisms are vitally important to improving the health of our soils. They also play a key role in making nutrients available to plants.
Soil organisms are naturally active during certain times of the year. Most are active during late spring and early summer when the soil is warm and moist. If the soil dries out during the summer months, soil organism activity will decline. During fall months, if there is rain or snow that moistens the soil while it is still warm, soil organisms may resume partial activity. As the soil cools in the fall, many organisms go dormant. It is important for gardeners to note that soil organisms help breakdown certain fertilizers and during the cool, dry months these fertilizers, if applied, will be less available for plants to take up.

Soil organisms are generally placed within three categories: organisms that are beneficial to plants, organisms that play a neutral role in plant growth, and organisms that are harmful to plants. Creating a favorable environment for beneficial soil organisms can improve plant growth and reduce garden maintenance. Encouraging their efforts is key to building a healthy fertile soil. Here are some ways you can encourage beneficial organisms in your soil:
- Add organic matter to the soil. Soil organisms require a food source from soil amendments (compost, crop residues) and/or mulch.
- Water effectively. Soil organisms are happiest in an environment that is damp, but not soggy. (Avoid over-irrigation because waterlogged soils will be harmful to beneficial soil organisms)
- Avoid unnecessary tilling, as it can destroy the mycorrhizae and soil structure. Instead of tilling, mulch for weed control.
- Avoid pesticide applications that aren’t necessary. Some fungicides, insecticides and herbicides are harmful to various types of soil organisms.
