When we think of bad weather in Florida, hurricanes are typically the first thing that comes to mind. In reality, Florida is 4th in the nation in tornado frequency—and when adjusted for frequency per square mile, we are actually number 1. Residents of Escambia County are believers now, as the community reels from enduring two tornadoes in the span of a week. Both rated as EF3 storms, the winds in the twisters (136-165 mph) were nearly equivalent to a Category 4 or 5 hurricane. The western Panhandle and much of south Alabama were under tornado watches as the most recent band of thunderstorms moved through.
Based on a thorough study of surviving trees after hurricanes in Florida, there are several species of trees best suited to windstorms. For north Florida, some of the top species are: Florida scrub hickory, several native holly species, Southern magnolia, sand live oak, myrtle oak, and bald and pond cypress. Data from the full study and an in-depth overview is available from the University of Florida. To prepare for a heavy thunderstorm or a milder hurricane, it is wise to replace or plant trees with the most wind-resistant species. Because of the damage from falling trees in storms, many homeowners are nervous about planting trees. However, there are so many benefits to healthy trees in a landscape that they vastly outweigh the small risk of them falling.
Keep in mind that tornadoes are the most violent natural disasters and may cause complete devastation of homes, neighborhoods, and forests in a matter of seconds. After the Escambia County tornadoes, we witnessed large uprooted trees, downed power lines, flipped vehicles and blown-off roofs. Several homes and apartments were completely flattened or blown off their foundations. Luckily, the odds are in one’s favor of not getting hit directly by a tornado—because there’s often little anyone can do for a landscape in that situation. It’s best to hunker down in a windowless inner room or hallway, which saved the lives of hundreds during the last round of bad weather.

However, there’s good news that work that can be done to help protect a home during storms. Hardening homes through “windstorm mitigation” techniques can prevent updraft from strong winds. A house is only as strong as its weakest area, and those are typically the connections between the walls, roof, and foundation. A wind-rated garage door and/or brace are crucial, as strong winds can enter a garage and blow out the roof above it.

In Escambia and Santa Rosa County, the local nonprofit “Rebuild Northwest Florida” operates a cost-sharing program to help residents harden homes. After the tornado in Century (near the Alabama border in north Escambia County), engineers from Rebuild examined a home that suffered a direct hit from a tornado. The home had been retrofit with crucial wind mitigation techniques and sustained no structural damage. Buildings, sheds, and homes all around it were destroyed. Examples of several wind mitigation techniques, including storm shutters, wind-rated windows, garage door braces and a tornado shelter are available for public viewing at the Escambia County Extension office in our windstorm mitigation building.
As the spring storm season heats up and rolls into hurricane season, keep in mind these suggestions for both the landscape and home. As always, contact your local Extension office if you have any questions.

Magnolias are well known plants to gardeners and many are familiar with the foliage and flowers of these plants. If you are looking for another earlier bloomer, you may want to consider adding a specimen selection to your landscape, the Star magnolia (Magnolia stellata).
Although not native to the United States, star magnolia is a slower growing multi stemmed deciduous shrub reaching about 15 feet in height over time. The best feature are the bright whitish pink star-shaped blooms appearing in late winter before leaves emerge. The flowers offer gardeners a peek of the spring to come and remind us that our Gulf Coast winters are not that long. 
Plants do best in soil with some organic amendments and mulch over the root systems. A planting area that receives a little afternoon shade is ideal but established plants will adapt to sunnier locations when irrigation is provided during drier weather. Only occasional pruning is required to remove crossing branches or those that grow out of bounds. Prune after flowering if needed.

Last Week’s temperatures have confirmed the winter of 2016 is not 100% over. Now is the time to plan that spring garden!.
Garden catalogs from every part of the nation are finding their way into many area homes. Their pages promise the buyer the potential for legendary success and the envy of their friends and neighbors.
After all, who can resist the full color beauty of giant flowers, large luscious fruit and vegetables which are sure to win a prize at the fair? There is not a runt, reject or cull in all the pages of these publications offering the mortal version of horticultural heaven.
Before ordering, the would-be gardener should consider several factors to increase the likelihood of a positive gardening experience. A failure will waste not only funds, but also much time and hard work and may introduce a long-term problem or two.
Cultivar selection for a tree, shrub, vegetable or fruit is critically important to producing the desired results. While a specific plant cultivar may grow and produce in one environment, it may not do so in all situations.
A common example of this problem is grape vines offered. Only muscadine grapes will grow and produce locally because Pierce’s disease kills other varieties.
Carefully examine the growing zones recommended by the catalog for specific cultivars. Check with fellow gardeners and the UF/IFAS Extension Office to see if they have any information or experience with any cultivars under consideration.
Heirloom varieties are especially sensitive to the variances in growing conditions. While they offer unusual and sometimes unique taste and culinary traits or landscaping characteristics, these antique varieties can be a challenge to grow.
Their genetic potential can make a consistent yield, especially for the novice growers, a real effort. Also, as an open pollinator variety, the results can be inconsistent.
Another question for the catalog company customer is new or untried plants varieties. Some of these plants are patented and few or no trials have been performed with them in north Florida’s growing zone.
Caution should be used when ordering these seed or plants. Being the first in North Florida to cultivate a new variety may require a large commitment of time and resources, and may produce only a large disappointment.
Check with fellow gardeners, local nurseries and your UF/IFAS Extension Office for available information on these new or patented varieties. It may save much wasted motion.
Lastly, be sure the plant or seeds under consideration do not have the potential as exotic invasive pests. As hard as this may be to believe, this does occur.
Some catalog vendors will advise buyers in the ordering instructions or at the time of ordering. Either way, the purchaser should check to verify the plant ordered does not have the potential to escape control and damage the environment.
Check out the following publications to assist with finding adapted fruit and vegetable varieties for North Florida.

Volunteers after lots of hard work mulching and adding compost to eight raised beds at The Shelter garden.
Have you ever been interested in volunteering at a school or community garden? Are you involved with a garden that could use some help? Well, UF/IFAS Leon County Extension recently started an Adopt-a-Garden program for volunteers to “adopt” a school or community garden for volunteer credit. Volunteers can teach hands-on gardening techniques, conduct educational talks and present displays at garden workdays, assist with garden planning and networking, encourage gardeners to work together, and help with any other activity that adds to the vitality of the garden. The program focuses on garden education and outreach as the primary objectives.
Volunteers hard at work planting fall vegetables in The Shelter garden.
The first major project of the Adopt-a-Garden program has been very exciting, with UF/IFAS Leon County Extension Master Gardeners “adopting” the new homeless shelter at the Kearney Center in Leon County. Master Gardeners lead the way in the organization and construction of eight raised bed vegetable gardens located on site directly behind The Shelter facility. They were awarded a community garden mini-grant from Leon County, which helped to cover garden supplies.
The Leon County Master Gardeners have received assistance from UF/IFAS Extension Agents, Florida State’s College of Social Work, and many other members of the community in gathering supplies and donations, recruiting volunteers, communicating with The Shelter staff, building and filling the raised beds, planting the garden, and maintaining the garden.
The gardening materials for The Shelter garden were generously supplied at no coast or at discounted costs by Lowe’s Home Improvement, Britt’s Dump Truck Services, Tallahassee Nurseries, Native Nurseries, Asplundh, and the FSU College of Social Work.

Leon County Extension and Leon County’s Office of Resource Stewardship will conduct shelter resident and staff garden trainings to ensure the garden is maintained and successful going forward. Extension’s Family Nutrition Program is currently offering nutrition education classes to shelter residents as well.
This project will allow shelter residents to get hands-on experience working in a vegetable garden, learn about different vegetable varieties, and taste their harvest, as vegetables that are grown in the garden go directly to The Shelter kitchen for meal preparation. The garden was officially dedicated as the Wendy Crook Memorial Garden by Leon County Government, with the dedication event reported by local television station ABC 27 WTXL. The article and video clip can be viewed here.
Along with the Wendy Crook Memorial Garden, other school and community gardens have been “adopted” by volunteers. If you are in the Leon County area and are interested in becoming a volunteer with the Adopt-a-Garden program, you can find out more information at the Leon County Adopt-a-Garden website or contact Extension Agent Molly Jameson, at mjameson@ufl.edu. Volunteers are encouraged to team up on garden projects and all levels of gardening experience are welcome.

Sedum rupestre ‘Angelina’ is an evergreen perennial that adds some pizazz to winter landscapes. This low growing plant performs well in sunny, well-drained spots in the landscape but will also tolerate some shade. In the summer, the foliage is a brilliant chartreuse but after a few cold snaps it takes on a coppery bronze tinge that brightens up winter landscapes.
Angelina sedum is an easy to grow groundcover that contrasts nicely with deep greens, burgundy, or black foliage. It grows well along the ground or in containers where it may drape down the sides. It roots where the stems touch the ground, but is not aggressive and can be easily divided and transplanted into new garden sites or shared with friends.
Small, delicate yellow flowers appear in the late spring or early summer but the plants are mostly grown for foliage texture and color.

A visit to a nursery and homeowners will see so many new selections of plants for the landscape. Some of these plants are new plant developments and may include plants we could not previously grow in Florida’s heat and humidity. One new plant series is the Southgate® Rhododendrons.
Anyone from more northern areas of the South is very familiar with the rhododendrons that offer showy spring blooms. Those particular rhododendrons just don’t make it in our Florida climate.
The Southgate® series from Louisiana were developed to be more tolerant of our weather conditions. Homeowners must still consider plant placement very carefully since these plants have some specific requirements even in Florida. Plants will do best in shade or filtered shade, especially in the afternoon. They do like an acid soil amended with compost and areas that are well drained. Homeowners will need to supply water during the growing season to maintain a uniform soil moisture.

Consider trying one of these newer rhodendrons if your landscape has a suitable spot and you will definitely enjoy a bright spot of color come spring.
Special Note: If you have animals or children be cautious since all plant parts are toxic if ingested.
