A month ago, when the Panhandle was covered in snow, it would have been hard to imagine that spring was just around the corner. But warm spring weather has arrived, and with it, the first of our native trees to bloom each year – the venerable Red Maple (Acer rubrum). Reliably heralding spring in Northwest Florida each February, Red Maples adorn our roadsides and low-lying natural areas with brilliant red blooms. Spotting a Red Maple blooming amongst the otherwise drab landscape means winter is on its way out and spring has sprung – or will shortly.
Beyond the blooms, Red Maple has much to offer as a landscape tree. For one, it is unbelievably adaptable. Across its native range – one of the most expansive of any species in the US, occurring naturally from Maine all the way down to the Everglades,* the tree can handle soils that range from periodically inundated along streams and other wet areas to more well-drained upland sites. Adding to its adaptability, in the Panhandle, Red Maple typically tops out around 40’ in height and around 20’ wide with a spreading vase shape, rarely growing out of scale with most landscapes.
*Since Red Maple occurs over a huge area of the US, it’s important to purchase seedlings or named varieties that hail from areas with like climate conditions to the Panhandle. Avoid varieties from northern states for best performance.
Red Maple is one of the few shade trees that has true four-season interest in our area. We’ve already talked about its spring flowers, but it also has attractive deep green foliage in the summer (some selections, like ‘Summer Red’ are even known for reddish purple new growth), famous fall color (though it is more muted in Florida than locales farther north), and unique ridged light gray bark in the winter. The seeds of Red Maple are even pretty. These two-winged seed structures, called a samara, follow the spring flower show, appear pinkish red, and are a favorite of squirrels and other critters.

Red Maple is a quick growing, low maintenance tree as well. If planted correctly and properly cared for, the species can grow several feet per year in its youth. Site the tree in a moist site that receives full sun, plant slightly higher than the soil level of the container the tree was purchased in to compensate for soil settling post-planting, and water regularly until established. After establishment, periodic fertilizing with a balanced fertilizer will help ensure Red Maple’s nutritional needs are met and maximum growth achieved.
If you’ve been looking for a medium-sized, native, flowering shade tree with four-season interest, Red Maple may be just the tree for your landscape. Plant one today!

Extension agents occasionally receive calls about “alien” bug sightings, sparking concern among residents. One such insect, Gonatista grisea, commonly known as the Grizzled Mantis, Florida bark Mantis or Lichen Mimic mantis, often raises alarm. But there’s no need to panic—this mantis is a fascinating and harmless part of our ecosystem.

The Grizzled Mantis is native to the United States, ranging from southern Florida to Georgia and South Carolina, and is also found in Puerto Rico, Jamaica, and Cuba. Adults are relatively small, with males measuring 36–38 mm and females slightly larger at 37–40 mm. Their grayish-green coloration and mottled dark markings provide excellent camouflage, allowing them to blend seamlessly into their surroundings, such as lichen-covered bark. They are characterized by triangular heads and large eyes, perfect for their ambush hunting style.
Quick and agile, Grizzled Mantids scuttle rapidly away from perceived threats. They exclusively prey on arthropods, adopting a head-down ambush position while resting on tree bark. Their preferred plants include sea grape, gumbo limbo, water oak, and magnolia, though they are not limited to these species.
Interestingly, mantids are gaining popularity as low-maintenance pets. Some enthusiasts collect egg cases or purchase late-stage nymphs. However, keep in mind that newly hatched mantids require ample food or separation, as they can become cannibalistic if resources are scarce.
Whether in the wild or as pets, the Grizzled Mantis is a unique and beneficial insect, playing a role in controlling arthropod populations. So, the next time you spot one, there’s no need for fear—just appreciation for this remarkable creature!

It’s almost March and it’s not just March Madness that’s about to happen, but No Mow March. This year will be the third year that the Horticulture Extension Agents of the UF/IFAS Northwest District have promoted No Mow March. The No Mow March campaign encourages those with lawns to leave some late winter/early spring wildflowers to benefit wildlife.

If you don’t think you’re ready to skip mowing the whole lawn for the whole month of March, then maybe you could try a small piece and hold off as long as you can. The point is to get you thinking of how your lawn, usually not considered an inviting place for most wildlife, can actually provide valuable ecosystem services. Many pollinator species in our area are emerging from their winter break and looking for food as we move into March. Plants in your lawn that are typically considered “weeds” are perfect pollinator feeders at a time when other landscape plants have yet to begin flowering. Providing extra floral resources can be especially useful in more developed areas where well-kept landscapes reduce what’s available for pollinators. Since the health and abundance of insect pollinators contribute to the ability of higher organisms, especially birds, if there’s more insects, then there’s more food for the birds, too!
While you’re not mowing, try observing the wild plants and animals that visit your lawn. You can get help identifying them by using apps like iNaturalist or Seek. You could also spend some time ripping out part of the lawn and planting a new flower bed of native plants. Or you can focus on identifying any invasive plant species in your landscape and work on removing them.

The Horticulture Extension Agents of the UF/IFAS Extension Northwest District have put together a No Mow March website with more information, including a list of related workshops and classes, as well as a pledge you can take to affirm your choice to participate.

As the temperatures warm into the 60’s (or greater) and the rain chance remains good, keep an eye open for disease in your lawn. Large patch disease is common in turfgrass this time of the year. It is caused by the fungus Rhizoctonia solani. The fungus is present in the soil and thatch layer year-round. When the temperatures rise into the 60’s and 70’s it begins to spread. Large patch thrives under these conditions, especially when the soil is wet. With frequent showers the disease spreads quickly. The first symptom of large patch is circular, discolored areas within the lawn. The outer borders of the patches are orange to yellowish in color. In the center of the circle there are grass blades trying to green up again. They are usually unsuccessful, resulting in odd-shaped patches of dying grass that begin to connect to each other.

A simple field diagnostic techniques to confirm large patch disease is to pull on the diseased grass shoots near the edge of the circle. The blades will come loose from the stolon easily. At the base of the leaves the stem and sheaths will appear dark brown and rotten. Yes, it is large patch.

If the weather gets colder or hotter very quickly, the disease will go back into dormancy. Looking at the long-range temperature predictions, the rest of February will be going up and down. Remember, the groundhog said six more weeks of winter. So, start looking for a fungicide or two or contact your pest control service. However, remember fungicides don’t cure existing problems. They are utilized as a protectant for the unaffected portions of the grass. When favorable conditions are present, the turf should be sprayed in order to keep the fungus from penetrating the grass blades. Repeat applications will be needed for as long as the weather is cool and wet. Check the product label for the correct intervals. Several cultural practices promote large patch infection including over-fertilization, over-irrigation, low mowing height, poor drainage and excess thatch. This spring, after the grass has greened-up on its own, is a good time to look at these factors and make corrections. Keep a close eye because as soon as the temperatures drop again in the fall, large patch can reappear if the corrections were not complete. For more information: https://edis.ifas.ufl.edu/lh044

Growing pansies in North Florida is a rewarding experience, as these resilient flowers thrive in cooler temperatures. As I walked up to our front office after the ice had melted away, I was amazed to see their vibrant blooms still standing strong, displaying their cheerful faces despite the harsh conditions of the January 2025 winter storm. Their endurance is a testament to their hardiness, making them a perfect choice for winter gardens. Here’s a guide to help you successfully cultivate pansies in our region.
Best Planting Time
Pansies thrive in cooler weather, making fall (October–November) the ideal time to plant them. Once established, they will provide stunning blooms throughout the winter and into early spring. While they can tolerate mild frosts, Florida’s summer heat is too intense for them, so they are best treated as a seasonal flower.
Choosing the Right Variety
Not all pansies are well-suited for Florida’s fluctuating temperatures. To ensure a successful and long-lasting display, select heat-tolerant varieties such as Majestic Giants, Matrix, or Delta Series, which are known for their resilience and vibrant blooms.
Delta Series – A popular choice for its bold yellow, purple, and blue flowers. This variety is highly valued for its disease resistance, vigorous growth, and ability to withstand both cold and mild heat.
Majestic Giants – A classic pansy cultivar known for its large, eye-catching blooms in a variety of colors and patterns. These compact plants thrive in both container gardens and mass plantings.
Matrix Series – This variety produces dense, bushy plants with large flowers, making it an excellent choice for creating colorful, impactful displays in both garden beds and containers.
By choosing the right variety, you can ensure your pansies thrive throughout the cooler months, bringing beauty and color to your landscape.
Sun and Soil Requirements
For the healthiest plants, provide full sun to partial shade, with at least 4–6 hours of direct sunlight each day. Pansies prefer well-draining soil rich in organic matter, with a slightly acidic to neutral pH (5.5–6.5). Improve your soil’s structure by adding compost or peat moss, which enhances both drainage and nutrient content.
Watering & Care
Maintaining proper moisture levels is key to keeping pansies healthy. Water them 2–3 times a week, ensuring the soil remains moist but not soggy. A layer of mulch will help retain moisture and reduce weed growth. To encourage continuous blooms, apply a balanced, slow-release fertilizer every few weeks and remove spent flowers (deadheading) to keep plants looking fresh and vibrant.
Common Challenges & Solutions
Despite their hardiness, pansies can face a few challenges:
Heat Sensitivity: If temperatures rise unexpectedly, pansies may wilt. Providing afternoon shade can help them cope.
Pests: Keep an eye out for aphids, slugs, and caterpillars. Use insecticidal soap or remove pests by hand to prevent damage.
Fungal Diseases: Avoid overhead watering to prevent root rot and mildew. Ensuring good air circulation will also help reduce disease risks.
Spring Transition
As spring temperatures climb, pansies will naturally begin to decline. To maintain a colorful garden, consider replacing them with heat-tolerant flowers such as zinnias, marigolds, or vincas, which can handle Florida’s warm and humid conditions.
Their cheerful, expressive blooms make them a wonderful choice for adding color and charm to your landscape. Happy planting!
