Every spring, a certain type of pollinator is busy in the yards and landscapes of our area. It may be alarming to see small piles of soil mounded up amidst carefully tended grass, but there is no need for concern. In fact, quite the opposite! The creatures making those mounds are bees, but they’re not the type that want to sting you. Instead, they’re harmless, solitary pollinators who just want a safe place to lay their eggs.

It’s easy to confuse a bee digging in the lawn or landscape for a yellowjacket and become alarmed. Yellowjackets are very different; they form hives underground consisting of hundreds or even thousands of individual hornets. Miner bees, on the other hand, each dig their own small burrow. Each miner bee is looking for the same sort of place to build a little hidey hole, so many individuals might be attracted to an area with prime real estate, so to speak. This can lead to large numbers of mounds in close proximity to one another, but again, there is no reason to be alarmed.

Each female bee will dig a vertical tunnel up to a foot and a half deep, then make side chambers lined with waterproof material. She stocks each chamber with pollen and nectar, then lays her eggs. Larvae remain in the ground until the following spring. When they emerge as adults, they start the whole process over again.
It is important to understand and protect pollinators such as the miner bee, because they all provide a valuable service to the environment. Pollinators ensure that all the plants around us can reproduce, by carrying genetic material from one flower to another. You can help these little messengers in their task by learning about their habits and making a little room for them in your landscape. When you see these small mounds of soil in your yard, don’t worry! The bees will do their job and the next rain will likely wash away the soil.
Consider attracting other pollinators as well! Plant flowers that attract native pollinators, or leave an area of your landscape “wild”. Let dead plant stalks remain over the winter as nesting sites for pollinators, or try letting a patch of native wildflowers escape mowing for some time in the spring.

With the arrival of spring weather in the Panhandle, many people have begun planning a vegetable garden. However, many gardeners that I talk to tell me more of their gardening frustrations than successes. I surmise the main reason for their frustration is simply doing what gardeners have done across centuries and all over the world, planting in the ground. That’s a great strategy in many places; unfortunately, in the Panhandle, we are not often blessed with great soil. We can overcome our poor soil conditions and be more successful by going above ground with raised beds!
Gardening in raised beds has three primary benefits for area gardeners: the ability to control soil conditions, reduce disease problems, and be space efficient. The first raised bed benefit is the most critical. Soil in and around much of the Panhandle is sandy in nature with little rich organic matter. To make matters worse, much of our native soil is either too well-drained and dries out rapidly or is the opposite and frequently stands in water – neither is conducive to garden success. We can alleviate all the above issues by creating our own perfectly draining, nutrient-rich soil environment inside a raised bed. One can either make their own soil concoction by experimenting with different ratios of compost, aged pine bark, peat moss, perlite, etc. or simply purchase bagged garden soil. I use either 100% mushroom compost or a 1:1 mix of mushroom compost & aged pine bark, but many soil component combinations work well.

Gardening in raised beds can also dramatically reduce the incidence of disease. Many of the most serious vegetable garden diseases like Bacterial Wilt and Late Blight in tomato are soilborne, surviving for years in the ground and only needing a splash of rainwater to transfer them onto your vegetable plants. Growing in beds with curated soil mostly alleviates this issue. Our sandy soils also tend to have damaging levels of difficult to control nematodes (microscopic round worms that feed on plant roots). Because nematodes prefer porous sandy ground, switching to raised beds with rich organic soils also removes that concern.
Finally, growing in raised bed gardens allows for a very efficient use of space. A typical raised bed is 4’x8’ in diameter, meaning you can site one nearly anywhere, regardless of how big or small your yard is. You don’t even need a yard space in some cases! If you have only a sunny porch or driveway, you can certainly mimic raised bed conditions with large containers. Most people are surprised by the amount of produce that you can pack into one or several 32 square foot raised garden beds, especially when you pay attention to plant mature size and group accordingly. The square foot gardening method is a great way to maximize raised bed produce yield.
If you have struggled in past years to produce a fruitful, high-yielding, mostly disease-free garden, your problem might be below your feet in the soil. As you plan your vegetable gardening activities this year, try gardening in raised beds and get ready for your best gardening season yet! For more information about vegetable gardening, raised bed construction, or any other horticultural topic, contact your local UF/IFAS County Extension office. Happy Gardening!
Hopefully, you are enjoying No Mow March. With the extra time provided by not mowing, you can spend more time trying to observe the diverse array of flowering plants coming up in your lawn. Often these are considered weeds, but a weed is just a plant you don’t like growing where you don’t want it. However, if we can find some beauty in these plants and appreciation for their role in supporting wildlife, then maybe we can turn it around and start thinking of them as wildflowers. As a trained botanist, I’m interested in all the flowers and think of how they grow, what eats them, what pollinates them, how their seeds are dispersed, and what niche do they fill in the ecosystem, even if that ecosystem is my residential landscape. Below are a couple of my favorite plants that come up in my infrequently mowed and/or unmowed lawn during the early spring.
Early Violet (Viola palmata)
This is the one that got me started leaving areas of the yard unmowed or infrequently mowed. Those violet-colored flowers were just too pretty to mow over, and I began giving them a wide berth. Now, I have little meadows of these native violets that spring up every year and give me great pleasure to observe.

Earthsmoke (Fumaria officinalis)
Not only is this one pretty, but it has one of the coolest common names of a plant that I know of. This non-native relative of the poppy plant has delicate foliage, reminiscent of the native columbine, with flowers mostly a light purple, but with a touch of dark purple towards the tips. The flowers also have a strange little twist to them. Part of my fondness for this plant is also tied to a memory from college. I was learning how to use dichotomous keys at the time and was so proud to have successfully keyed this one out. My identification was confirmed by our taxonomy professor, who I greatly admired, and I think he was a little proud of me, too!

This one is related to earthsmoke, but in a different genus and just happens to be a native. It also has similar delicate foliage and a twist in the flowers, but these come in yellow.

Mock Bishopsweed (Ptilimnium capillaceum)
This native carrot family relative, with small flower clusters and delicate, wispy leaves, is not one that jumps out at you as being super showy. However, being a carrot relative, it is a great larval host plant for the swallowtail butterflies.

Horrid Thistle (Cirsium horridulum)
The common name says everything about how most people view thistles. Thistles definitely get a bad reputation due to those spiny leaves, but our six native species are a boon for pollinators. Being in the Aster family with many flowers grouped together, it provides lots of easily accessible pollen and nectar resources. This one is also a known host plant for the little metalmark and painted lady butterflies, which somehow find their way around all of those spines. I really enjoy the artistic symmetry of the leaves, and also the spines that surround the flower in bud, especially when the dew has collected on it and the light hits it just right.

Southern Dewberry (Rubus trivialis)
Probably another hard sell for leaving in the yard, but this prickly native plant rewards animals, including us, with delicious fruit. This one is best left in a low trafficked area where it won’t grab you.

Venus’ Looking Glass (Triodanis perfoliata)
This native beauty ties for second coolest common name, which is a reference to the shiny covering of the seed. Related to bellflowers and lobelias, Venus’ looking glass shoots up in the early spring and has beautiful purple blooms atop a wispy inflorescence (flower stalk). You’ll find several pollinators visiting this lovely little wildflower.

No Mow March is a perfect opportunity to spend time learning more about the non-turf species living in your lawn. There’s a lot more than the list above and your local extension office can help you identify what you’re seeing. You can also use the iNaturalist app for help in identifying these little pretties. If you use iNaturalist during March, please add them to our No Mow March project. For more information on No Mow March, please visit https://sfyl.ifas.ufl.edu/escambia/lawn-and-garden/no-mow-march/.
The oncoming of spring is heralded by several events. Wildflowers bloom, temperature rises, and insects awaken from their wintry slumber. The latter of these is the impetus for this article. I’m sure you have heard the buzzing of the bees already, but there is more to come. Florida is host to 315 species of native bees in addition to honey bees (Apis mellifera) which are a non-native species. Native bees in Florida are separated into six families, fulfilling several niches within our landscape. This article is only focused on a few of these.
The Sweat Bees
The sweat bees fall into the family Halictidae. These vary greatly in appearance and size with the majority being very small. Often metallic black, but may also be seen in shades of green, blue, or purple they are hard to miss in your landscape. Most sweat bees are ground nesting though some can be found above. Wildflowers, stone fruits, and sunflowers are the primary nectar sources for these bees particularly in early spring.

Bumble Bees
Bumble bees (Bombus spp.) are in the family Apidae. Ground dwelling, the queen overwinters in the soil emerging in early spring to feast on wildflower nectar. Often mistaken as carpenter bees (Xylocopta spp.), they are distinguishable by the hairs covering their bodies which are lacking in carpenter bees. They are one of two bee species seen carrying pollen sacks, honey bees being the other. All but one of the five species in this genera may be found in the Panhandle where they are important pollinators for many native and ornamental plants.

Mason Bees
One of our more unique species, Mason bees of family Megachilidae live above ground lining their nests with mud. Solitary by nature, these are prominent pollinators of fruit trees and blueberries. A variety of color makes them difficult to even identify as a bee. They often come in dark blue, black, or white striped. Much like honeybees, some species of mason bees are purchased from online sources specifically for orchards.

Carpenter Bees
Carpenter bees are the final subject covered here and are split into two subfamilies. Large carpenter bees (Xylocopta spp.) chew their nests into solid wood. That the wood is sometimes fence posts, water tanks or your home means that this insect may be an economic pest. These are large and as mentioned above often mistaken for bumble bees. Small carpenter bees (Ceratina spp.) are differentiated mainly by size as they are much smaller than the large carpenter bee. They may be a variety of colors as well and nest by hollowing out the pith of broken or burnt plant stems. As they make their nests in already broken plant tissue, they are not considered of economic importance.

Conclusion
Native bees are an important part of pollination in the Florida Panhandle. It is worthwhile to get to know which species are active in your landscape. Provide habitat and nectar to them, and they will help your plant life bloom. For more information on creating habitat for native pollinators, see this Ask IFAS document, or contact your local extension agent for additional information on this and any topic regarding your gardens and more.
Do you enjoy a tasty bowl of fruit in the morning? Or maybe a hot steaming cup of coffee? If the answer is yes, then raise (or tip) your hat to our pollinators. About 75% of food crops depend on pollination to some extent, but pollinators provide the bulk of the pollination for over 80% of the world’s flowering plants. A pollinator can be birds, bats, or even small mammals but, insects such as ants, bees, beetles, wasps, butterflies, and moths do the bulk of the pollination that affects our daily lives.
Plants normally benefits from attracting a particular type of pollinator to their flowers, ensuring transfer and hopefully resulting in reproduction. The pollinator benefits from its adaptation of a particular flower with different traits to access nectar and pollen. These floral traits include odor, color, size, flower shape, reward type, amount, nectar composition, and timing of flowering. This plant pollinator interaction is known as pollination syndrome.
Did you know –
That tubular red flowers with a lot of nectar often attract birds.
Also, foul smelling flowers attract carrion flies or beetles.
Butterflies and moths can help spread pollen; however, they don’t have any specialized structures for collecting pollen.
Beetles pollinate more than 80% of all flowers – clusters of flowers are ideal because beetles are clumsy fliers.
While bees are drawn to plants on the blue, white, purple, and yellow color spectrum. Bees possessing hairs and other specialized anatomical structures that can readily collect and transfer pollen, making them an important plant pollinator. However, the honey bee, (Apis spp.) is the world’s top pollinator and is responsible for one-third of what we eat, yet they are just a small representative of all the bee species.

Did you Know-
Everyone can contribute to pollinators by creating a home garden. Pollinators will make use of food and habitat anywhere it is found – roadsides, open fields, pastures, backyard flower gardens etc. One can be pollinator friendly by doing any of the activities below:
Plant an assortment of plants – varying in color, size and type to support a greater number and diversity of pollinators.
Plant nativeplants – as they are considered the best choice due to their abundance of nectar and pollen, among other benefits.
Use little or no pesticides – instead maintain a sustainable garden with the suitable plant species that will support natural beneficial insects—reducing the need for pest control.
Educate– others about the importance of pollinators.
Seasonal planting – Choose pollinator plants that bloom in spring, summer, and fall. Timing is crucial – plant flowers in clumps that bloom in early spring (emerging winter hibernation) and late summer (preparing for hibernation) so bees have adequate food supply.
Provide habitat or installbat boxes. Bats play a vital role in pollinating flowers and dispersing seeds.
