UF/IFAS Bay County Demonstration Garden Goes Virtual!

Have you ever visited a public garden or a park and wondered what type of plant you were looking at? Or found the name on a sign but wondered – can I grow that at my house? How big will it get? Does it have flowers, berries, keep its leaves in the winter? We feel your pain, fellow plant lovers!

Gardens are ever evolving and providing up to date printed information on all the plants can become difficult to manage and involve a lot of wasted resources. In Bay County, we have several gardens at the Extension Office, and we try to keep everything labeled, but space on signs is limited to plant name and we want to teach gardeners how to grow not just identify plants. To expand outreach of Florida-Friendly plants, we have created a website with all the plants in our demonstration gardens.

The site is organized by garden area, common name, and botanical name to ease navigation. Each plant profile has photos at different stages, basic cultural information, and links to additional research-based information.

Whether you are visiting our gardens in person or just want information on plants that perform well in the Florida Panhandle, we hope you will check out our new site and let us know if you found it useful and how we can improve.

Tips on Building Raised Bed Gardens

Tips on Building Raised Bed Gardens

Want to grow a vegetable garden but don’t know where to start?

Raised bed gardens give you the ability to put a garden anywhere you have at least six hours of sunlight and access to water, regardless of your native soil type.

See the fact sheet below (Or Click Here for the downloadable PDF version!) for tips on how to build a raised bed vegetable garden. And be sure to reach out to your local Extension office with any questions!

Planting Depth Problems Continue

Planting Depth Problems Continue

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. 

Gardening with Native Plants

Gardening with Native Plants

The interest and use of native plants in the landscape in Florida and the southeastern U.S. has increased significantly over the last 20 plus years.  There are many benefits for including them in our landscapes including creating a wider biodiversity and enjoying the multitude of support for butterflies, wildlife, and unique color displays.

Choosing the plant species that works in landscape sites requires a few considerations like being adaptable to the site conditions, soil type and preparation, understanding the plant establishment needs, and finding plants regionally to your area.

Develop a landscape plan that includes addressing soil and site preparation as many landscape sites are altered during the construction phase with the soil being drastically changed.  In Florida many sites need soil backfill to raise the elevation for buildings, drive or parking areas to remain above flood challenges.  Choosing the right plant for the right place will need to include understanding the plants’ growing environments.  Do the plants perform best in well-drained drier areas or moister situations with slight flooding tolerances?  Native plants have acclimated to specific soil settings over thousands of years.  When selecting the plants for your landscape, perform a site analysis with soil texture, drainage, soil pH, hours of direct intense sun or shade in the growing season, air circulation in the growing area, and growing space available.  Doing your homework first can save a lot of money and frustration later.  Visit the local nurseries to see plant availability.  Just remember many landscape settings do not always match the natural habitats where many of these plants are established in nature.

Soil amendments will likely be needed to improve the soil conditions and provide optimal plant establishment and performance.  Most often the soil that brought in is sandy and nutrient poor with little to no organic matter.  In addition, the soils are compacted by heavy equipment during the construction phase.  These factors can create native plant challenges leading to poor growth and shortened plant life spans.  When the soils have been addressed according to plant needs the selected plants can be placed and the fun part begins by following the landscape plan.

With the landscape conditions likely altered with amendments, choose plants that can establish and grow successfully in these often more difficult conditions.  Florida red maples (Acer rubrum), Live Oaks (Quercus virginiana) and Sand Live Oaks (Quercus geminate) all can provide shade areas for future plantings.  Butterflies attach to and feed on butterfly weed (Asclepias tuberosa) and swamp milkweed (Asclepias incarnata).  Butterfly weed does well in well-drained sandy soils and swamp milkweed likes it moist.  These are just a few of the many plants out there to consider.  Just remember to visit your local nurseries and talk with them about native plants and availability.  Enjoy your gardening adventure.

Pruning Hydrangeas

Pruning Hydrangeas

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.

Plan on Doing a Fall Garden, Plan Now!

Plan on Doing a Fall Garden, Plan Now!

Yay, we are halfway through with August and our summer is winding down!  This is the perfect time to start prepping for that fall garden.   Growing a productive fall vegetable garden requires thoughtful planning and good cultural practices.  This process consists of selecting a site, planning the garden, preparing the soil, choosing the seeds and plants, planting a crop, and nurturing the plants until harvest time.  In the Florida Panhandle it can be a challenge to get cool season crops started; there is a balance in starting them early enough to allow them to mature (50-60 days) before a hard frost and getting them through the end of a hot summer.

August and September are the main planting times for a fall garden.  There are several cool-season crops and a final crop of warm-season vegetables that can be planted.  Some good warm season crops are lima beans, cucumbers, eggplant, peppers, and tomatoes.  Going into September it will be a good time to establish strawberry plants.  Some good vegetables to start growing just around the corner are broccoli, carrots, cabbage, collards, mustard, and Swiss chard.  https://edis.ifas.ufl.edu/NorthFloridaGardeningCalendar  Herbs that do well are cilantro, parsley, and lemongrass. Mint, oregano, and thyme should be planted in containers as they tend to spread. Mexican tarragon, mint, rosemary, and basil will also do well in September. See Herbs: http://edis.ifas.ufl.edu/topic_herbs

Transplants from the local garden center will get the garden off to a fast start while seeds will offer more varieties to choose from.  It is also important to think about your location.  A vegetable garden can be in the ground, a raised bed, or even grown in containers.  Your plants will need more than just a place to grow.  They will also need sunlight, water, air, soil, fertilizer, and care.  Most vegetables require at least 8 hours of sunlight.   Keep an eye out for pest problems such as insects, diseases and weeds because they will continue to flourish in warm temperatures and high humidity. To help conserve soil moisture a layer of newspaper and mulch can be placed between the rows.  Mulch also aids in weed control.

The result of a beautiful, successful vegetable garden is fresh produce to eat, share with neighbors, family, and friends and even the possibility to sell your harvest.  With patience and practice your gardening skills will improve every year!  Follow the above few tips and you will be well on your way to a great harvest!  For more information about starting a fall garden or any other horticultural or agricultural topic, contact your local UF/IFAS County Extension Office.
