When thinking about what it means to be successful in planting your garden or having fruit trees, often the first thing that comes to mind is a healthy quality crop. This starts with the health of your soil. We will have two specialists that cover soil health and the benefit of adding cover crops to your rotation during the off season. The second thing that might come to mind when wanting to be successful is how to start? how much time do I have to devote to gardening? and how much do I want to do? This meeting will also have a specialist coming to Marianna to cover how to get started on a property with a specialty crop. Even though this information may be geared towards new farmers, it could also be very useful to new land owners and community residents just wanting to do more on their property. You may find that you have so much extra produce that you want to have a little fruit stand!
There will also be a session on the importance of drip irrigation, fertigation and how to implement these practices. Drip irrigation will not only save you money in the long run with the use of less water, but it is also much better for overall plant health by reducing pest and disease problems. Fertigation is the process of adding soil amendments, water amendments and other water-soluble products into an irrigation system. This process can be both beneficial to the plants and cut back on the time it would take to fertilize by hand.
The next session on specialty vegetable and fruit crops will teach about the various exciting specialty crop opportunities in the Tri-State area such as artichokes, blackberries, Seminole pumpkins, and more. Finally, the meeting will also cover cucurbit disease updates and will be extremely useful if you already have a field or garden of watermelons, cucumbers, or squash! Come with questions! CEUs will be offered as well if you are a homeowner that holds a pesticide license.

While, the audience for this conference is primarily small to medium sized, diversified cucurbit and vegetable producers in the tri-state region including the counties in the Panhandle, Alabama, and Georgia, the residential community is welcome to attend and will truly benefit with learning about soil health, cover crops, fertigation, drip irrigation, and specialty crops. The conference will be held at the Jackson County Extension Office in the Peanut Hall. We are planning a full morning with educational sessions and lunch to follow.
This meeting will be $5 at the door and pre-registration is highly encouraged. Please call our office at 850-482-9620 to reserve your seat and if you have any questions.
Tri-State Fruit and Vegetable Meeting
Thursday, January 26, 2023, 8:00 am- 1:00 pm at the Jackson County Agriculture Offices Auditorium, 2741 Penn Ave., Marianna.
Taste and size of citrus fruits are important attributes that determine profit. Since, consumers prefer firm citrus fruit, packing houses only accept fruits of specific size without softness. Therefore, fruit that grow too large and don’t fill out properly are unmarketable and growers discard all these types of fruits. This condition is called puffiness. As fruit diameter becomes ever larger, fruit pith (the area between flesh and the peel of fruits) becomes thick and causes the fruit to shrink inward and lose its normal spherical shape. So far, this problem has been observed in both backyard and commercial Satsuma groves in North Florida, South Georgia, and Southeast Alabama. Citrus puffiness is a threat for all growers from an economic and overall yield point of view, because puffed fruits are unmarketable resulting reduced profit margins.
With increasing puffiness, the pith of the citrus fruit increases that makes it soft and fruits lose its usual round appearance.
Possible causes
A few scientific reports suggest that low fruit loads on citrus trees can cause puffiness, but the actual mechanism of puffiness still need to be explored. Based on observations, the team from our lab (Fruit Physiology lab, NFREC, Quincy) and collaborators lead by Dr. Muhammad Shahid has concluded that there are three possible causes of puffiness in citrus i.e., genetic, environmental, or nutritional. In our next phase of research, we will dig deep into this issue and try to determine what is the actual cause of puffiness. Fruit puffiness is observed more in young (4-6 years) satsuma groves than in mature groves. Puffiness on old trees could be due to fruit setting on late blooms during hot conditions. Overall, fruit puffiness is less of a concern in sweet oranges, limes and lemons as compared to satsumas.

Puffiness study by Fruit Physiology Lab, NFREC, Quincy
In our preliminary study, we divided puffiness into five different grades based on fruit size. Grade one is marketable fruits (firm without puffiness). Fruit diameter and puffiness increase gradually in grades 2, 3, 4, and 5, respectively. We have collected fruits from different groves in north Florida and the common denominator among these fruit was decreased Brix value (a common measure of sweetness) with increased puffiness. Average fruit diameter with maximum puffiness was around 40cm and these puffy fruit weighed around 475g. With increasing puffiness, peel weight was increased while juice contents were reduced – not great!
Most satsuma groves in North Florida have some degree of puffiness. However, amount and grade of puffiness varies by grove. In our observations, citrus groves in South Georgia also have puffy fruit, which clearly indicates that puffiness is not geographically specific and can develop in any citrus growing region. After visiting a number of farms in North Florida, we concluded that puffiness is mostly an issue with the Satsuma cultivar ‘Owari’ regardless of different rootstocks. Having said this, we can’t say with confidence that puffiness couldn’t appear on other varieties of citrus without further study. We are carefully monitoring all our variety evaluation trials at the UF/IFAS North Florida Research and Education Center (NFREC), Quincy, in collaboration with citrus breeding and postharvest experts from Citrus Research and Education Center (CREC) and Indian River Research and Education Center (IRREC). We are working on different aspects of citrus production including nutrition, crop load, and pruning to identify the actual cause of puffiness and how to effectively mitigate it in Satsuma groves in north Florida.
Several times each month I am diagnosing shrub and tree problems in Escambia County that are related to the same issue, improper planting. Symptoms of this problem can be slow growth, leaf browning, and dieback. Sometimes under stressful weather conditions like drought, plants completely die.

This is a difficult sight for homeowners who have invested time and money in a tree or shrub to enhance the landscape. In some cases, the planting issues can be fixed but there are other times when a new plant will need to be installed.
The good news for homeowners is that this is a completely preventable issue. The University of Florida has excellent publications with photos about installing and caring for trees and shrubs. My Panhandle colleagues and I have also shared numerous articles and videos on proper plant installation.
Care must be taken during installation to set your plant at the correct depth. Even if a landscaper or nursery is installing the plant for you, check their work. Make sure the rootball is cut or sliced, it is not set below grade, that any straps holding the rootball are cut after it is set, and proper backfilling occurs without soil over the top of the rootball.
You don’t want to find out later in the season or even year’s later that your plant declined just because of planting problems.
Tropical milkweed, Asclepias curassavica, has become a commonly grown monarch host plant in many gardens. It grows very well in our climate and survives into Fall and Winter during many years. This long life of Tropical milkweed is not necessarily a good trait for the monarch butterfly. In the Fall, monarchs are in migration mode and need to move out of our area to overwinter in warmer climates. Live host plants that are found during migration may interrupt the process. An additional problem is that Tropical milkweed may be host to a disease caused by a parasite that can impact the health of Monarch butterflies. The best tip to help our migrating Monarch butterflies, is to cut back your Tropical milkweed to the ground each Fall or better yet, grow native milkweeds that usually die back on their own.
Weeds are basically unwanted plants or plants growing out of place. Proper identification and some understanding of how and why weeds are present in a lawn are important when selecting the best management tactics. All turf weeds can be grouped into one of three life cycles: annual, biennial, or perennial.
Annual: Produces seeds during one season only
Biennial: Produces seeds during two back-to-back seasons
Perennial: Produces seeds over many seasons
Knowing the types of weed previously present in an area also can help one to be better prepared and what control measures to employ in the future.
Weeds may appear in multiple categories, either broadleaf, grass, or Sedges/rushes.

Broadleaves, or dicotyledonous plants, have two cotyledons (seed leaves) when the weed seed germinates.
Appearance: Broad, flat leaves with net-like veins and usually have showy flowers.
Common types: Clover, ground ivy, dandelions, chickweed, plantain, henbit, beggarweed.
Grasses are monocotyledonous plants that have only one cotyledon, or seed leaf, present when seedlings emerge from the soil.
Appearance: Narrow leaves with parallel veins in their true leaves. Hollow rounded stems.
Common types: crabgrass, goosegrass, crowfoot grass, bull grass, annual bluegrass, alexander grass, cogon grass, torpedo grass, and smut grass.
Sedges/rushes. Both favor a moist habitat. Appearance: triangular-shaped, solid stems, while rush stems are round and solid.
Common types: yellow and purple nutsedge and, to some degree, globe, Texas, annual, and water sedge.
One of the first steps in managing weeds is to have a healthy dense lawn/ turf to provide shade that prevents seed germination. Having a healthy lawn depends on turf species selected – making sure you put the right plant and right place. Other factors that influence a heathy turf and a reduced amount of weeds include proper cultural control, fertilizing regularly, mowing at the appropriate height, watering deeply, reducing traffic, pest control, and sanitation. If you only have a few bothersome weeds in your lawn, you may be able to dig them up by hand—but if your lawn is overrun with weeds, you may need to start from scratch. If you decide to start from the beginning, you have a choice ahead of you. Do you want to lay down seed or sod? There are pros and cons to each.
Seed
Pros: Less expensive, more variety
Cons: Takes longer to germinate, can only lay at certain times of year depending on grass type
Sod
Pros: Instant grass, can lay any time of year, requires little maintenance
Cons: More costly, less variety in grass can mean less healthy lawn overall
To prepare the soil after either method, make sure you till it down to roughly 6 to 8 inches.

We grow many types of hydrangeas in North Florida. In order to prune your hydrangeas at the correct time of year, you need to identify which types you have in your garden.
Bigleaf hydrangea (Hydrangea macrophylla) Bigleaf hydrangea (Hydrangea macrophylla) comes in mophead and lacecap flower forms. They bloom on old wood, so prune in summer after blooming is finished. Repeat bloomers, such as ‘Endless Summer’ bloom on both old wood from the previous year and on the current season’s wood. You can prune after the first bloom and still get a bloom later in the season.

Oakleaf hydrangea (Hydrangea quercifolia) A native hydrangea that blooms on old wood, so prune after flowering. This type requires little pruning, only to maintain size and shape.

Panicle hydrangea (Hydrangea paniculata) These shrubs bloom on new wood, so prune in winter or early spring before new growth emerges. ‘Limelight’ and ‘Pee Gee’, are examples of this type. Plants only require pruning to shape or thin out the shrub.

Here are some additional pruning tips for your hydrangeas.
For all types, check for winter-damaged wood in early spring. Remove all dead branches before buds start to open. Some plants need rejuvenation pruning. Old wood may die back or be less productive, so in early spring remove very old stems at the base. This stimulates new growth. Deadheading flowers (cutting off spent blooms at a set of leaves) can happen as needed.
