Now is the time for Northwest Florida gardeners to plant strawberries for bountiful production of fruit beginning in January and continuing into May. The following procedure will lead to a successful strawberry garden if followed:

The best location for strawberry production provides well-drained, moist, sandy soil with substantial organic matter. It must not be too wet. A fertilizer scheme of 2 lbs of a 6-8-8 fertilizer per 100 sq ft should be broadcasted over the plot, and spaded or disked in. Prepare the bed by leveling out the soil.  Commonly, a preferred system is the development of a hill system, which entails making a raised bed 6-8 inches high and 24 inches wide. A raised bed can be filled with well-rotted compost mixed at a 50:50 rate with soil. After bed preparation, provide another application of fertilizer in a single, narrowband in the middle of the bed, 4 to 8 inches deep, but DO NOT apply fertilizer directly below the plants, as the fertilizer may burn the young transplants. Do not use fertilizer with more than 6% nitrogen on strawberries, so that they have less chance of burning and greater chance of setting sweet, quality fruit.

Short day, certified disease free plants for Florida such as Sweet Charlie and Camarosa should be purchased from a reputable nursery.

If growing the plants using plastic mulch or grow fabric, put drip irrigation underneath in the form of drip emitters or bubbler type soaker hose.

When setting out the transplants:

  • Keep plants moist before planting
  • Spread roots out in fan-shape
  • Set plants in moist soil at the correct depth. Do not cover the plants crown with dirt or leave its roots exposed above the soil.
  • Space plants 12 to 18 inches apart.
  • Pack the soil firmly around the roots, then sprinkle with water. Overhead sprinkling may keep the tops from drying out until the roots can get established.

For best results, strawberries should be mulched. Black polyethylene plastic mulch at 1 to 1½ mil thick is best (completely cover the top and sides of bed before planting). Be sure the bed is firm, formed correctly, moist, and fertilized adequately. Place soil on the edges of the plastic to hold it in place. Cut slits in the plastic for the transplants.

When using alternatives like straw, bark or other natural organic materials mulch to a depth of 1 to 2 inches, but do not completely cover the plant.

Permaculture Practices for the Home Landscape

If you’ve attended any of our landscaping classes, then you’ve probably heard the phrase “Right Plant, Right Place”.  This phrase is a simple reminder to research plant growth habits and growing conditions before making selections for your landscape.  This not only holds true for ornamental plants, but for edible crops as well.  A term used to describe the use of edibles as ornamentals is “Permaculture”.  Now this is an extremely simplified definition of the term, but permaculture comes from a combination of the words “permanent” and “agriculture”.  The thought behind permaculture is to fashion an edible landscape after a natural ecosystem.

There are a number of strategies to becoming a successful permaculturist.  Below you will find a few examples.

  • Site Observation and Analysis – The slope, orientation to the sun, and sectors of your yard should all be documented.
    • Slope – Identifying the slope of your yard can help you determine the natural flow of water and nutrients.  For example, if you have a hill in your back yard you may want to install some plant beds between the peak of the slope and your house.  These beds will help absorb water and nutrients before they have a chance to reach the house.
    • Orientation – Think about the location, relevant to your house, of each of your edible landscape areas.  The eastern side of your house receives morning sunlight, which is much cooler than the western side of your house that receives sunlight in the afternoon.  A tomato plant will be much happier if it can avoid the afternoon heat.
    • Sectors – While walking your property, you will notice differences in soil texture, soil moisture, and the plants and weeds growing in these different areas.  You can divide your yard based on these characteristics along with slope, orientation, and shade percentage to develop sectors of your property.
  • Cover Crops and Living Mulch – Cover crops are planted in areas that you would normally allow to go fallow.  Living mulches are plants that are planted alongside edible plants to help fill voids.  The benefits of both are listed below.
    • Weed Supression
    • Erosion Control
    • Produce and/or Scavenge Nutrients
    • Nematode Supression
    • Harbor Beneficial Insects

  • Space Utilization – The third criteria is to mimic a forest.  Just like any good forest, your “forest garden” will consist of different layers of vegetation.
    • You can start by planting large deciduous trees such as pecans or pears farthest from the house.  These trees will allow filtered light to penetrate the layer below.
    • Next, you can plant smaller fruit trees such as citrus or peaches along the understory of the larger trees.
    • Then, you can plant your vegetable and herb garden around your fruit tree plantings.
    • Finish by planting root and vining vegetables such as carrots or sweet potatoes at the edge of the forest.

We’ve just scratched the surface of the concept of permaculture, but I encourage you to dig a little deeper.  What could be the harm with being able to eat your landscape?  Just don’t eat too much or you may lose your landscape entirely!

An “Intermediate Permaculture” class is scheduled for Saturday, September 23 at the Jackson County Extension Office.  For more information, please call (850)-482-9620 and ask for Matt.

Citrus Canker in Northwest Florida

Citrus Canker in Northwest Florida

In November 2013, citrus canker was found for the first time in the Florida panhandle in Gulf Breeze in southern Santa Rosa County. The Florida Department of Agriculture and Consumer Services (FDACS) tested and confirmed the disease on grapefruit trees in a residential landscape. Since that time, citrus canker has been confirmed on citrus trees at 27 more locations in Gulf Breeze. To my knowledge it has not been found in any other location in the panhandle. Not yet.

Citrus canker is a serious bacterial disease that only infects citrus trees. It will not infect any other plant species nor is it a threat to human health. This highly contagious disease has no cure as yet. Severely affected trees experience substantial leaf and premature fruit drop and serve as a source for infecting other citrus in the area. The disease spreads through wind, rain and transportation of infected plant material from other locations.

We do not know how the disease came to infect trees in our region. The disease could have been spread through infected fruit or trees brought here from areas where the disease is established, such as central or south Florida.

What should you do if you suspect your citrus is infected with this disease?

  1. Look at Homeowner Fact Sheet: Citrus Canker for more information.
  2. Leave the tree in place in your yard and call the Division of Plant Industry at FDACS at 1-888-397-1517 for a free inspection and testing of your citrus trees.
  3. Consult your local Horticulture Extension Agent for more information and control/removal strategies.
  4. Proper removal of infected trees is recommended to prevent the spread of citrus canker but is not mandatory.

Love Blueberries? Thank the Blueberry Bee!

Love Blueberries? Thank the Blueberry Bee!

This time of year, blueberry bushes are flowering and small fruit are coming onto the wild and cultivated bushes in north Florida. Many of us, myself included, look forward to the late-spring harvest of blueberries, taking our children out to u-pick operations and digging out family recipes for blueberry-filled desserts.

What many do not know, however, is that there’s a specialized bee that literally lives for this season. During the last few weeks, this little insect has been furiously pollinating blueberry bushes during its short, single-purpose lifetime.

The Southeastern blueberry bee, Habropoda labriosa is active only in mid-March to April when blueberry plants are in flower. They are smaller than bumblebees, and the yellow patches on their heads can differentiate males. Blueberry pollen is heavy and sticky, so it is not blown by the wind, and the flower anatomy is such that pollen from the male anther will not just fall onto the female stigma. Blueberry bees must instead attach themselves to the flower and rapidly vibrate their flight muscles, shaking the pollen out. Moving to the next flower, the bee’s vibrations will drop pollen from the first flower onto the next one. This phenomenon is called “sonicating” or ‘buzz pollination” and is the most effective method of creating a prolific blueberry crop.

Blueberry bees do not form hives, but create solitary nests in open, sunny, high ground. Females will dig a tunnel with a brood chamber large enough for one larva, filling it with nectar and pollen. After laying an egg, the female seals the chamber and the next generation is ready. The species produces only one generation of adults per year.

By the time we are picking fresh blueberries next month, you probably won’t see any blueberry bees around. However, we should all consider these insects’ short-lived but vitally important role in Florida’s $82 million/year blueberry industry!

The Visual and Delectable Appeal of an Edible Landscape

Edible landscaping has become a trend for many gardening enthusiasts. A combination of edible plants along with traditional ornamentals can create an artful presentation. There are some challenges when designing such a landscape, but in those challenges opportunities’ may be found. One of the most difficult challenges is making sure your garden or landscape is healthy and vibrant year-round since many edibles are short-lived annuals. These include plants such as eggplant, pepper, lettuce, artichoke and some annual herbs. There is a solution to this concern. First, know your edible plant’s propagation and maturity months. This way you can offset plantings to ensure color in your landscape. Another key measure is to mix some evergreen ornamentals in with short season edibles and long season edibles. Examples of long season edibles include berry shrubs, fruit trees and biennial or perennial herbs.

When designing your edible landscape, think about style and theme to help guide you through the process. A formal design has more straight edges and geometric shapes, whereas the more natural approach has meandering edges and irregular shapes. A color scheme in harmony is very important. Remember, an edible landscape should not just be a production food garden but a visual treat. The goal is not to grow a high yield garden, but only to produce supplemental edibles to make the endeavor worthwhile.

Dr. Gail Hansen, Associate Professor of Environmental Horticulture at the University of Florida, has developed twelve ideas when creating an edible landscape:
  • Combine reliable, low-maintenance ornamental with edible plants. Use evergreen ornamentals to maintain enough green structure, so that potential cool season bare spots are not visual.
  • Use support structures for an artistic effect and to assist in growth of some plants. Trellises, arbors and even tomato cages are some examples that can be used.
  • Use containers in areas to keep the landscape more organized. Planters will also help in maintenance, as plants will be easier to reach and the soil will be easier to manage.
  • Create some hard edges in your landscape. Raised beds, garden walls and borders will give defining lines to the landscape and promote a clean appearance.
  • A pathway through the landscape will both provide an access to plants and give an inviting appeal. Brick pavers, gravel and mulch are good examples of pathway material.
  • Remember color is key. Create a visually pleasing combination of plant color, form, texture and sizes.
  • Always start by keeping it simple. So, start small and simple. Then, you can begin filling in the landscape.
  • Look for one unique feature to create an added interest to you landscape and provide growth to plants. This could be a shade house for ferns and other hanging baskets or a hay bale, where lettuce, tomatoes or peppers could grow upon.
  • Select appealing and easy to grow plants that you want to eat!
  • Let plants reach maturity before taking them out of the landscape. For example, rainbow chard will grow larger, if allowed to continue to grow after seed has been produced.
  • Use the Florida-Friendly Landscaping principle, “Right Plant, Right Place”, when adding edibles to your landscape. Match the growing needs with the most suitable location.
  • Consider your location and layout for irrigation. All plants need some degree of water. An above ground drip irrigation system is usually the most flexible and adjustable irrigation method in regards to overall plant watering needs in a landscape.

 

Following Dr. Hansen’s ideas will help you create the edible landscape of your dreams. For more information on edible landscaping, please contact your local county extension office for more details.

Citrus Greening (HLB) A Troublesome Bacterial Pathogen

Citrus Greening (HLB) A Troublesome Bacterial Pathogen

Small Fruit vs Normal

If we look at the big picture when it comes to invasive species, some of the smallest organisms on the planet should pop right into focus. A microscopic bacterium named Candidatus Liberibacter asiaticus, the cause of Citrus Greening (HLB), has devastated the citrus industry worldwide. This tiny creature lives and multiplies within the phloem tissue of susceptible plants. From the leaves to the roots, damage is caused by an interruption in the flow of food produced through photosynthesis. Infected trees show a significant reduction in root mass even before the canopy thins dramatically. The leaves eventually exhibit a blotchy, yellow mottle that usually looks different from the more symmetrical chlorotic pattern caused by soil nutrient deficiencies.

One of the primary vectors for the spread of HLB is an insect called the Asian citrus psyllid. These insects feed by sucking juices from the plant tissues and can then transfer bacteria from one tree to another. HLB has been spread through the use of infected bud wood during grafting operations also. One of the challenges with battling this invasive bacterium is that plants don’t generally show noticeable symptoms for perhaps 3 years or even longer. As you would guess, if the psyllids are present they will be spreading the disease during this time. Strategies to combat the impacts of this industry-crippling disease have involved spraying to reduce the psyllid population, actual tree removal and replacement with healthy trees, and cooperative efforts between growers in citrus producing areas. You can imagine that if you were trying to manage this issue and your neighbor grower was not, long-term effectiveness of your efforts would be much diminished. Production costs to fight citrus greening in Florida have increased by 107% over the past 10 years and 20% of the citrus producing land in the state has been abandoned for citrus.

Classic blotchy mottle in Leaves

Many scientists and citrus lovers had hopes at one time that the Florida Panhandle would be protected by our cooler climate, but HLB has now been confirmed in more than one location in backyard trees in Franklin County. The presence of an established population of psyllids has yet to be determined, as there is a possibility infected trees were brought in.

A team of plant pathologists, entomologists, and horticulturists at the University of Florida’s centers in Quincy and Lake Alfred and extension agents in the panhandle are now considering this new finding of HLB to help devise the most effective management strategies to combat this tiny invader in North Florida. With no silver-bullet-cure in sight, cooperative efforts by those affected are the best management practice for all concerned. Vigilance is also important. If you want to learn more about HLB and other invasive species contact your local UF/IFAS Extension office.
