Blackberries are a deciduous crop that thrive in temperate climates. While several native blackberry species grow wild in Florida, their small fruit size, late maturation, and low yields make them unsuitable for commercial production. Historically, cultivated blackberry varieties in Florida, have been primarily limited to homeowner production, but, UF/IFAS researchers are working to change that. Through the development of improved cultivars with higher yields, better flavor, and little to no chilling hour requirements, blackberries are becoming a more viable option for commercial and small-scale growers in North Florida.
UF/IFAS invites you to learn more about blackberries and the current research associated with blackberry production at the Blackberry Field Day, on Wednesday, June 18th. This event will be held from 8:30 – 11:30AM Eastern Time, at the UF/IFAS North Florida Research & Education Center (NFREC), located at 155 Research Road, Quincy, Florida.
This is a free event aimed at educating home gardeners, farmers, landowners, and industry representatives about production practices such as proper planting, pruning, and fertilization. Attendees will be able to tour the blackberry planting at the UF/IFAS NFREC as well as sample different blackberry varieties! The field day aims to present attendees with the potential benefits, challenges, and current research associated with growing blackberries in North Florida.
Attendees will be able to visit the blackberry planting at UF/IFAS North Florida Research & Education Center in Quincy. Light refreshments will be provided. Space is limited, so please register using the link below or by calling 850-875-7255 to reserve your spot!
Extension Agents get used to hearing that the local Extension Office is the community’s best kept secret. As much as we try to let folks know we’re here, many are still unaware of the services we provide. Even amongst the residents that are familiar with us, some of the services available remain unknown, especially our identification and diagnostic services. Here’s a rundown on some of the services available through your UF/IFAS Extension service.

Soil Testing
This is probably our most well-known service, but it’s worth a reminder. For only $3 (pH only) or $10 (pH plus plant macro- and micro-nutrient values) per sample, plus shipping, you can have your soil analyzed in a state-of-the-art facility. To be clear, soil testing only provides a reading of your soil’s chemistry, specifically pH (acidity/alkalinity) and plant nutrient values. It does not provide information on any diseases or potential toxins that may be present in the soil. In addition to the results, you can specify the general type of plant you’re trying to grow (various grass species, vegetables, citrus, general trees and shrubs, etc.) and the report will provide recommendations to adjust the nutrient levels to be sure that plant is able to thrive. Your local agent receives a copy to help answer any questions you may have about the results or recommendations. More about soil and nutrient testing can be found at the Extension Analytical Services Laboratory website.

Plant Disease Diagnosis
UF/IFAS Extension has a great plant pathology lab on campus, but we also have a great resource close by in Gadsden County at the North Florida Research and Education Center’s (NFREC) Plant Disease Diagnostic Clinic. For a modest fee of $30, you can submit a sample of a diseased plant, and the lab manager will use the available methods to confirm the presence of disease and identify the disease-causing organism. Just like with the soil test results, you are provided with a recommendation on how to best treat the disease. The NFREC Plant Disease Diagnostic Clinic website has submittal forms, contact information, and directions for collecting a quality sample.

Plant and Insect Identification
While your local extension agent enjoys receiving plant and insect identification, there is an online submittal option available to use as well through our Distance Diagnostic Identification System (DDIS). You can set up an account and then upload photos of plants, insects, mushrooms, even diseased plants, and an expert on UF’s campus will do their best to identify it for you. The DDIS website has more information to help you set up a user account.
The Florida Cooperative Extension Service has many ways to help Florida citizens diagnose their landscape issues using science-based methods conducted by experts in state-of-the-art facilities. The above services are just a selection of the diagnostic capabilities available. To see a complete list, visit the IFAS Diagnostic Services website. You can always contact your local extension office, too, for assistance in identifying plants and insects, as well as diagnosing diseases.
Gardening just wouldn’t be any fun without the pests. In this episode of Gardening in the Panhandle LIVE!, the hosts answered some very important questions about different types of pests in Florida lawns and landscapes. Before we talk about some of the specific topics from this episode, it’s critical to know the definition of a pest when it pertains to our yards. A pest is any organism that is harmful and/or damaging to humans or the property of humans such as crops and livestock. Weeds are pests, some insects are pests, and diseases are pests.
Integrated Pest Management or IPM for short is the use of different pest management strategies to help control pests. The UF/IFAS Publication Landscape Integrated Pest Management provides more details on the steps involved in a good IPM program.
As stated above, pests can come in a lot of forms. Pesticides offer control for some pests. The article The Basics of Pesticides provides more information on using pesticides.
Some annual weeds are easier to control as the germinate. Pre-emergent herbicides provide a barrier that kills most annual weeds shortly after they germinate. Apply pre-emergent herbicides in late winter before day temperatures reach 65°F–70°F for 4 or 5 consecutive days and in the fall when nighttime temperatures drop to 55°F–60°F for several consecutive days.
The first step of IPM is to scout for pests. More information on scouting can be found in the article Scouting: The tip of the IPM spear from Matt Smith with the UF/IFAS Extension in Lake County.
The larva of many beetle species like to eat turfgrass roots. More information on June beetles and their control can be found in the fact sheet June Beetles (White Grubs).
Snakes usually help us control pests around our homes. If you’re interested in what snake species live in Florida, then you’ll want to read the UF/IFAS publication Managing Conflicts with Wildlife: Living with Snakes.
Fire ants are a direct pest of humans and the create some unsightly mounds in the yard. A number of baits are available on the market to help keep them out of the landscape. The article Sustainable Fire Ant Control offers more details on baits and other fire ant control strategies.
Mole crickets are another type of insect that feed on turfgrass roots. The Mole Cricket IPM Guide for Florida is a great place to start if you’re trying to understand this pest better.
If you’re sticking with an edible landscape theme, then you’ve certainly encountered leaf-footed bugs and stinkbugs on your fruit and vegetable crops. Larry Williams with the UF/IFAS Extension in Okaloosa County has written a very informative article on leaf-footed bugs titled Leaf-footed Bugs Are Common On Tomatoes.
Pests can wreak havoc on healthy lawns and landscapes. The resources and advice provided in this episode of Gardening in the Panhandle LIVE! will help you maintain a beautiful setting to enjoy. To view this episode of Gardening in the Panhandle LIVE! please visit our YouTube channel.
Spring and summer bring an explosion of color to gardens, and among the most resilient yet misunderstood flowers are marigolds. Growing up in a small Caribbean town, marigolds were everywhere. Locals called them “Stink and Pretty” or even “graveyard flowers” for their bold scent, but their benefits were undeniable. Whether used in traditional medicine, religious rituals, or tucked into garden beds to keep pests at bay, marigolds have always been more than just a flower.
More Than Just a Bloom
Belonging to the Tagetes genus, marigolds come in a variety of cultivars, each offering unique traits and advantages. Beyond their beauty, they play essential roles in soil conditioning, pest control, especially against nematodes, and companion planting.
A Closer Look at Marigold Varieties
Marigolds fall into distinct categories, each with different growth habits, flower forms, and benefits. The two most common types are Tagetes patula and Tagetes erecta.
French Marigold (Tagetes patula)
Compact and bursting with warm hues of orange, yellow, and mahogany, French marigolds are excellent pest deterrents. Often planted alongside vegetables, they help manage soil nematodes while thriving in borders and containers.
African or Perfection Yellow Marigold (Tagetes erecta)
Despite the name “African,” this species hails from Central America. Taller and more dramatic than French marigolds, it produces large, showy golden blooms ideal for cut flowers and mass plantings.
Signet Marigold (Tagetes tenuifolia)
Delicate foliage, small dainty flowers, and an edible twist—Signet marigolds are a favorite for adding color to salads and attracting pollinators. Plus, their milder scent makes them perfect for gardeners sensitive to stronger fragrances.
A Common Mix-Up
It’s worth noting that while often called “Pot Marigold,” Calendula officinalis is not part of the Tagetes genus. Though it shares similar colors and benefits, calendula is better known for its medicinal properties and edible petals.

Next time you pass a tray of marigolds at a plant sale or see them brightening a garden bed, take a second look. These unassuming blooms do far more than add beauty—they may just be the unsung heroes of your summer garden.
