2025 has already been a year for the books, as Winter Storm Enzo has proven that it really can snow in the Sunshine State. With the fluffy white snow also comes below freezing temperatures, therefore most landscape plants that fit the hardiness zones of Florida are not cold-tolerant or what is also called “cold-hardy.” In the Florida Panhandle, freezes are becoming more prevalent in recent years, so it is best to act ahead of time to protect your patio and landscape plants from feeling the adverse winter affects.
Preparation in Advance

It is always best to do your research and know what hardiness zone(s) your plants will thrive in. This will help you understand the level of cold tolerance the plant can withstand and will allow you to select cold tolerant varieties that will grow best in the Florida Panhandle. You can find your hardiness zone by using this link: https://planthardiness.ars.usda.gov/.
Proper care throughout the year will also help your patio and porch plants withstand freezing temperatures; a healthy plant has a better chance of recovering from cold damage than an unmaintained one. A freeze event can usually be spotted in the forecast multiple days in advance, and it is best to be proactive by moving potted plants that would be adversely affected to the indoors or to a warmer sheltered area.
Cold Protection Tips
One of the most effective ways to protect your plants from cold weather is covering them up during the night. Frost cloths can be purchased at most garden stores or through online platforms. If you are unable to buy frost cloths, you can use breathable materials such as old bed sheets or burlap bags that will still allow for air flow to the plant but keep it insulated and warm.

You can also use mulch for insulation. Applying a thick layer of mulch around the base of your landscape plants will help insulate the soil to regulate ground temperatures and protect the plant’s root system from cold weather damage. Pine straw or leaves will work best and should be applied in a 3-to-4-inch layer kept away from the base of your stem or trunk of the plant. In some cases, it may be necessary to use an outdoor heat lamp, but always ensure that it is placed away from any flammable materials and only used as needed.
It has been said that using your irrigation at home can be a form of freeze protection. This is typically not effective for a homeowner. When farmers run irrigation to protect their crop, the irrigation systems that are used commercially are designed for scenarios like this. The irrigation must be run for several hours after temperatures rise for this method to work and protect the plants. With a home irrigation system, this is considered water-wasteful and the amount of water a home irrigation system emits can turn into heavy ice quickly, which will damage your plant rather than offer protection.
Cold protection for plants in Northwest Florida is all about preparation. Whether its covering plants, adding mulch to your landscape, or moving your plants indoors, a little effort can go a long way in preventing cold damage. With a bit of TLC, you can keep your landscape and garden beautiful all year long.

This is the time of year where we often pledge to change and/or improve something about ourselves, but why not have a garden resolution, too. If you’d like a garden resolution or you’ve run out of personal resolution ideas (and you’re a gardener), then I have a couple of suggestions to help you garden with purpose this year.
Try to Accept more Imperfections in Your Landscape
Just like maybe we shouldn’t be so hard on ourselves or family members, we should also give our landscapes some grace. It’s hard to be perfect, and most landscapes have some minor, mostly aesthetic, imperfections, but that’s okay. Consider these landscape imperfections signs of character and what make it unique. Try to focus on the positive qualities of the overall landscape and not fixate on minor insect damage or a weed or two in the lawn. You may find that many of these issues clear themselves up on their own and your anxiety, worry, and efforts were not needed.
Reduce Pesticide Use
Somewhat dovetailing with accepting more imperfections, try and pledge to use less pesticides in your landscape. Many pesticides are applied in an attempt to fix minor landscape problems that often go away on their own. Based on numbers collected by various agencies, gardeners apply literal tons of pesticides to their ornamental landscapes. These products have environmental impacts and are often not fixing the problem, due to misdiagnosis, wrong timing of application, and/or other improper usage.

Plant More Native Species
When thinking of new plantings or browsing the nursery, consider selecting native species for your landscape. Native species are more adapted to our native insects, diseases, soil conditions and climactic patterns. Native plants aren’t necessarily easier to grow – you still need to take care to get them well established – but they tend to be better able to handle the environmental stressors of our area. Additionally, native plants are most likely to benefit native wildlife species.

When looking for those native plant species, try to support your local nursery businesses. Local nurseries tend to only carry the plants that are best suited to the area, and they’re your neighbors, too. To help find both native plant species and local nurseries, there is an association of Florida native plant nurseries (the Florida Association of Native Nurseries – FANN) that has a wonderful online search tool to find the perfect plant from the closest nursery.
Of course, don’t forget to utilize your local extension office if you decide to take on these resolutions. Whether it be help confirming that it is just a minor imperfection, help diagnosing a disease or insect problem, selecting native plant species, and or finding a local plant nursery, your local extension office can lead you in the right direction. UF/IFAS Extension’s Gardening Solutions webpage and Florida-Friendly Landscaping™ Program site also have plenty of online resources to help you have another successful and sustainable gardening year.
Well folks, the earth has made yet another trip around the sun, and we find ourselves in another of hopefully many a new year. The weather has been cold, but it’s important that we spend a few moments plotting a strategy for our lawns in the coming year. Lawncare is a subject which is shrouded in myths and often misunderstood. Luckily, a little bit of knowledge can help you achieve stress free healthy turfgrasses.
Lifecycle
The first thing homeowners should understand is how turfgrass grows throughout the year. Turfgrass is split into warm and cool season species. You may have guessed that in the Florida Panhandle, warm season grasses are dominant. These grasses perform well in warmer weather going dormant when temperature begins to fall. During this dormant period, these grasses turn brown and may appear to have died. The grass itself is alive and well, but the roots have died back significantly.
Fertilizers
Why is this an important piece of information? There is no point in applying fertilizers to turfgrasses with no ability to absorb them. Instead, waiting until mid-April (think Tax Day) for fertilizers provides two key benefits. First, it allows time for the grass to develop a thick mat of roots. As roots are the main tissue for nutrient entry into plants allowing your lawn to utilize the applied nutrition. Second, waiting until a little later evades late season freezes. Cold weather may harm early season growth which stresses your lawn which could cause die back allowing weeds to take over.

Weed Prevention
The subject of weeds brings us to a critical cultural practice in terms of lawncare. The application of preemergent herbicides. These herbicides are designed to create a barrier in the top 1/2 inch of soil which prevents shoot and root growth after weed seed germination.
Now, it’s important to understand, there are hundreds of thousands of weed seeds in the top layers of soil all over the world. Weeds take advantage of open spots in your lawn as does any plant in any ecological system.
A preemergent herbicide prevents weed from being able to fill those spaces, by preventing their growth. Given the proper watering and fertilization, your grass may now fill these voids. Your lawn will outcompete the weeds and become its own preventative.
Selecting and application of a pre-emergent herbicide does have some nuance. Not every product is compatible with every grass type, consult our Weed Management Guide to select a product that will work for your lawn. Another concern is application timing and frequency. Multiple applications will likely be required in the spring due to those triggers which break seed dormancy combined with product efficacy timelines. Local extension offices are a great resource for specificity, but generally application will need to be mid-February with a second application 6-8 weeks later based on the product label. Also important to note is that this is a long-term process. It may take a few years of spring and fall application to eradicate the weeds in your lawn.

To Sum Up
Turfgrasses make excellent groundcovers and are look best when grown as stress free as possible. In the early parts of the year that entails holding off on fertilization and adding a layer of protection for summer weeds. Getting to know your turfgrass and familiarizing yourself with proper cultural practices will go a long way to making a healthy lush lawn. For more information you may read through our Florida Lawn Handbook or consult your local Extension Agent.
Camellias have been a part of the landscape in the Southeastern United States for over 200 years. They are native to Asia and were introduced near Charleston, South Carolina in 1786. The common name camellia refers to varieties and hybrids of Camellia japonica and to lesser known varieties of C. sasanqua and C. reticulata. The growing conditions in Northwest Florida are well suited for many camellia varieties. Camellias can serve several functions in the landscape including foundation plantings, screens, accent plants, background groupings and hedges. Maximum benefit can be achieved by mass plantings or groupings. Single plants should be focal point in beds rather than randomly placed throughout the lawn. Camellias flower in the fall and winter when their display of colorful blooms is most appreciated. During the remainder of the year their evergreen foliage, interesting shapes and textures, and relatively slow growth make camellias excellent landscape plants. Some camellia growers enjoy competing in flower shows and manipulate the flower buds to achieve larger and earlier flowers. This involves removing competing flower buds and applying gibberellic acid (a plant hormone). Individual cultivars can be selected for size and form ranging from small and irregular to large and upright. Texture and foliage color also differ among the various species and multiple varieties. Midseason flowering varieties that bloom from November through January are best suited for Florida conditions. Warm fall temperatures may prevent early varieties from flowering properly. Late-blooming selections may attempt to send out new leaves before the end of the flowering period which results in “bullnoses”. Bullnosing is characterized by poor quality flowers which do not open fully and may even drop while still tight buds. Extended dry periods while in the bud stage can make the condition more likely. While flowering, camellias need 1 inch of water applied each week. Camellias perform best in partially shaded locations which are enhanced by good drainage and air movement. Fertile, acidic soils high in organic matter are preferred. The soil must be well drained because camellias will not grow in wet areas. Do not plant them in areas with a high water table and/or hard pan. This will result in a shallow root system which is more susceptible to injury during dry periods. Camellias should be installed where cold air can move in and out freely, but the area should be protected from strong northwest winds. Plantings under established trees or in areas that have structures to block the wind are usually injured less by cold temperatures. These conditions enable the plants to gradually thaw or warm in the morning before being exposed to direct sunlight. Dense shade may result in sparse foliage and poor flowering. Camellias exposed to full sun may appear yellow-green, but may yield more flowers. Either situation is stressful to the plants and can lead to pest problems. Tea scale is the most common insect on camellias. Scales generally feed on the underside of leaves and may not be noticed until large populations have developed. Symptoms include very small elongated white and/or brown raised “flakes” on the underside of leaves that turn yellowish in color.
