Often, Extension agents are tasked with evaluation of unhealthy plants in the landscape. They diagnose all sorts of plant problems including those caused by disease infection, insect infiltration, or improper culture.
When evaluating trees, one problem that often comes to the surface is improper tree installation. Although poorly installed trees may survive for 10 or 15 years after planting, they rarely thrive and often experience a slow death.
Fall/winter is an excellent time to plant a tree in Florida. Here are 11 easy steps to follow for proper tree installation:
Look around and up for wire, light poles, and buildings that may interfere with growth;
Dig a shallow planting hole as wide as possible;
Find the point where the top-most root emerges from the trunk;
Slide the tree carefully into the planting hole;
Position the point where the top-most root emerges from the trunk slightly above the landscape soil surface;
Straighten the tree in the hole;
Remove synthetic materials from around trunk and root ball;
Slice a shovel down in to the back fill;
Cover the exposed sides of the root ball with mulch and create water retention berm;
Stake the tree if necessary;
Come back to remove hardware.

Intense red fall color of Japanese Maple in Georgia is hard to replicate in our climate. J_McConnell, UF/IFAS
Fall is a favorite time of year for many people. Cool nights, short days, football games and the fast approaching holidays are all signs of summer coming to an end. Floridians who have relocated from other parts of the country may be disappointed to realize we get very little showy fall color even though we can grow some of the same trees in North Florida as other parts of the country. Why is that? Well, although plant breeders may promise “showy fall color” in certain selections, they really can’t promise that year after year because it’s more than just genetics influencing leaf color. Let’s take a deeper dive into the science behind fall color!
Why do the leaves change color? Lower temperatures and shorter day length indicate to plants that winter is approaching and some physiological changes start to occur. Chlorophyll is a pigment found in leaves that, in addition to capturing sunlight and producing energy, also causes plants to display green during the growing season. As fall approaches, environmental changes tell plants to stop producing chlorophyll and existing pigment begins to break down. The reduction of chlorophyll allows the other pigments present (carotenoids and anthocyanin) to reveal their colors in an array of yellows, browns, oranges, reds, and purples. Different plants have different levels of these pigments and some may not exist at all in certain species. This explains why some plants typically turn only yellow and others may show yellow, orange, and/or red!
Why is there so much difference from year to year?
Variation occurs because environmental conditions and cultural practices play a part in determining how much color will be on display. Rainfall or irrigation amounts in the preceding summer and fall, drought cycles, nutrient levels, sunlight, and day and night temperatures all influence color from year to year.
How do I increase the potential for showy fall color in my landscape?
Choose plants with the reputation of producing desired fall colors in our area. However, keep in mind that because of the influence of outside conditions, you may be in for a surprise from year to year. To increase your chance of having a somewhat predictable fall display, use cultivars instead of seedlings of a plant species. A cultivar is a selection of a plant species that has been chosen for desirable traits, like growth habit, flowering, or fall color. These attributes are usually easily identified by the way their names are assigned. For example, Acer rubrum ‘October Glory’ is a red maple cultivar known for a full rounded canopy and exceptional red fall color. The reason that cultivars appear more consistent is because they are genetic copies of the parent plant that they are named for. A species or seedling plant is not a clone but comes from seed, which means you will get as much genetic variation as you see in human siblings. Just like children in our own families, each will each shine in their own way and no two will be exactly alike.
The North Florida garden has experienced some cold weather damage and even though you want to start pruning back your perennials, now is not the time. Many damaged plant stems protect perennials that return from the roots. Learn about care of cold damaged plants with UF IFAS Extension Escambia County In the Garden. #colddamage#coldprotections
Cilantro is an herb that grows well in the cooler months of North Florida gardening. Beth Bolles will share how to grow and use cilantro in the latest Garden to Table feature from UF IFAS Extension Escambia County.

Landscapes are an ever-changing setting that can be fun to view as the seasons come and go. We all have differing ideas of what an exceptional landscape should be. The point to always keep in mind is what you and your family like. Are you considering the Florida-Friendly Landscaping elements? You always want to keep a healthy, attractive environmental sound landscape. This brings many interesting design concepts to the table.
The kitchen table is exactly where a landscape design needs to begin. My dad was just the opposite, he would receive or buy plants on impulse. Load up all these three-gallon plants, take them home and plant without consideration the long-term growth, color combinations, time of bloom and many more topics. He just loved working in the yard and growing plants.

There are basic principles of landscape design that are used as a guide. While I may stray from them from time to time, I always return to these principles. Just keep in mind that a landscape is an ever-changing living setting that we will always work to improve. The visual elements are based on what you see first when you enter a setting and are usually the vibrant high impact plants that may include bright bloom color, size of plant, focal plantings, leaf size and others. The other side of the visual is the subtle presence of low impact plants with softer colors, small leaves, lower growing plant size. This visual group often is planted en mass with a flow of plants to create a calming effect for the visitors to your landscape.
When the form of the plant is being considered, there are several points to keep in mind. Will it have a three-dimensional impact in the landscape setting? Is the landscape a small backyard or a one-acre open setting? What are the maintenance requirements of the plant(s) as they mature in size? A large tree can dominate a small area, but it may be just what is needed for shade with low plantings around it. In a large setting, multiple large trees may be needed to create a focal point. I have seen some wonderful tree alleys that help in directing the flow of the landscape down drives, walks, and paths. These forms should be considered for all plants in the landscape including, trees, shrubs, groundcovers and even hardscapes.

Up next is the texture of the plant(s). Are you looking for large and coarse or small, “softer” leaves? You may find finely textured plants along paths or at entry areas to steps, softening the hardscape of the steps. Are the large leaved plants open and airy, allowing light to flow through? Large coarse leaved plants may be found at the back of landscape beds with fine textured smaller plants in front creating a three-dimensional look or even used as a focal point to pull the gaze of the eye to a determined location.
Color in the landscape has just as much impact as the plant texture, size and form. Color can bring a bold or a soft statement. The color is often thought of from blooms, but leaves too change in color with the seasons, from a fresh new bright green, purple, red or other colors in the spring to deeper, more mature colors as summer comes in. Trunks can also bring unique colors to the landscape from subtle yellows to cinnamon.
There are so many things to think about when creating a long-term vision for your landscape. Many options come in the decisions that will need to be made. Do your research and always contact your local Extension office for more information!
Who doesn’t like strawberries, right? Backyard gardeners grow these low-growing herbs throughout the state and there is a significant commercial industry too, as Florida’s climate is ideal for cool season production.
Strawberries like well-drained sandy soils, so they’re a perfect fit for many areas in the Panhandle. Strawberries should be planted in the months of October or November as the plants are quite cold hardy. Shorter days and temperatures between 50°F and 80°F are ideal for fruit development.

Strawberries are also very versatile. You can plant them in the ground, in raised beds or even containers. Transplants should be planted 12” to 18” apart, with 12” row spacing. For best results, use a rich soil balanced with compost and sandy soil and both fertilize and water regularly. Mixing in 2 ½ pounds of 10-10-10 fertilizer into a 10’ x 10’ bed space should be sufficient to start. A sprinkle of fertilizer applied monthly throughout the growing season should also help ensure a solid yield.
Berry production begins to ramp up roughly 90 days after planting, but plants will continue to produce throughout the spring. When the weather gets warmer, the plants start to expend energy into producing runners instead of fruit. These runners will be new fruit producing plants for next season.
Transplants can be purchased from most garden centers. There are many varieties on the market, but “Florida-Friendly” cultivars include “Sweet Charlie”, “Camarosa”, “Chandler”, “Oso Grande”, “Selva”, and “Festival”. “Camarosa” has proven to be the most productive variety in North Florida. Any of these varieties are capable of producing two pints of fruit per plant.
As stated earlier, Florida has a significant strawberry industry and UF/IFAS has a supporting role. The UF/IFAS Gulf Coast Research and Education Center (GCREC) is home to the Strawberry Breeding Program. Cultivars are developed by traditional means, for the Florida commercial industry on an 11,000+ acres research site. Appearance, shelf life, sweet flavor and disease resistance are just some of the areas of selected breading research that is conducted on site. There is also a white strawberry soon to be released!
