The Great Southeast Pollinator Census began in Georgia in 2019 with the goals of increased pollinator habitat, teaching the public the importance of insects, and providing useful data to researchers. 2024 is the first year for Florida to be included and we want to support this project with strong participation. View the webinar from the Northwest District Horticulture Team that teaches how to identify pollinators as well as how to collect and submit data for the 2024 Great Southeast Pollinator Census.
Caring for African Violets: A Guide for Enthusiasts

African violets (Saintpaulia ionantha) are beloved houseplants known for their vibrant blooms and ease of growth indoors. Since their introduction to the United States, they have become favorites among plant enthusiasts for their adaptability and stunning flowers, making them staples in homes and offices. African violets thrive in bright, indirect light and moderate temperatures, and they come in various flower colors, including pink, purple, white, and combinations of these hues. Here’s how to ensure your African violets thrive with proper watering, fertilizing, and propagation.
Watering
The quality of water is crucial for African violets. Use water that is safe for drinking, making sure it is at room temperature or slightly warmer to avoid causing yellow spots on the leaves. The watering needs of African violets vary based on soil mixture, drainage, light, temperature, and humidity. For example, clay pots require more frequent watering than plastic pots due to higher evaporation rates. Water your African violets when the soil surface is dry to the touch or if wilting is noticeable.
There are two methods to water African violets: top watering and bottom watering. For top watering, apply enough water to saturate the soil and discard any excess that drains out. For bottom watering, place the pot in a container with about an inch of water. Once the soil surface becomes moist, remove the pot, let it drain, and discard any remaining water. Self-watering pots are also an option, and you can create one by making a “water wick” from a material like a braided nylon stocking. Insert the wick into one of the pot’s drainage holes and ensure it reaches the bottom of a water reservoir. Whether you water from the top or bottom, avoid letting the plant sit in water.
Fertilizing
African violets benefit from regular feeding with water-soluble fertilizers like 20-20-20 or 15-30-15. Mix the fertilizer at one-fourth the recommended rate and apply it every time you water, ensuring the soil is moist before application. If your plant shows signs of needing nutrients, such as gradual loss of leaf color, reduced growth, and fewer flowers, fertilize and observe for ten days. Be careful not to over-fertilize, as this can result in tight centers and rusty-appearing new leaves.

Propagation
Propagating African violets is simple and can be done using leaf cuttings. Choose a healthy leaf from the middle of the plant, snap or cut it off, and trim the petiole (leaf stem) to about 1–1.5 inches. Insert the petiole into a propagation medium. Roots typically form at the petiole base within three to four weeks, new leaves appear three to four weeks and flowering occurs six to nine months later.
Additional Tips
When purchasing an African violet, it usually adapts well to its container for a while. Although these plants prefer a crowded environment, repotting them annually into lightweight potting media is advisable.
Maintaining sanitation is essential to prevent diseases. Ensure all pots, tools, and materials are clean before use. With proper care and attention, African violets can flourish, bringing beauty and joy to any indoor space. By following these guidelines on watering, fertilizing, and propagating, you can enjoy healthy and vibrant African violets in your home. for more information, contact your local Extension Office or click on the links below:
I don’t know if you’ve noticed, but it’s been hot outside. Like really, scorching, hellacious, dog days hot. In this weather pattern we’ve been in, it’s hard to make yourself do non-essential stuff outside that doesn’t involve swimming and so our gardens go by the wayside. In my opinion, that’s totally okay! Give yourself a rest from the garden and landscape chores for the next couple of weeks and get your fall gameplan ready. The following are some things to think about over the next few weeks to prepare yourself for the coming cooler weather!

Get your soil tested. If you’re an in-ground vegetable gardener or just like to have an attractive lawn/landscape, performing a simple soil test can offer either peace of mind that your soil’s pH and fertility is good or give you a nudge to schedule some needed amendments. Though I don’t recommend fertilizing lawn grass this late and there’s no need to fertilize the garden before it gets planted in mid-late September, you can certainly begin to source and price fertilizer for the appropriate time based on your test results. However, now IS the perfect time to get lime out in a vegetable garden if your pH has sunk beneath the recommended 6.5. Lime takes weeks to months to begin to alter soil chemistry so the sooner the better if it is needed!
Order seeds. While I love to support local farm stores and plant nurseries, you are limited with the vegetable and flower varieties you can plant by what they have in stock. I enjoy trying new/improved and heirloom plant varieties each year and, most of the time, these can only be found by ordering online. For the latest in vegetable and cut flower varieties with a nice mix of heirloom cultivars thrown in also, I can recommend Johnny’s Selected Seeds, Baker Creek Heirloom Seeds, Seed Savers Exchange, and other similar purveyors – all of these are great places to look. Continue to purchase your more common standbys through local outlets but, this year get different and try new things by ordering online!
Develop a garden/landscape plan. I doubt there’s a gardener amongst us who wouldn’t like to rearrange things a bit outside. Maybe you planted your lettuce a little too closely together last year, you’ve been dreaming of installing a new flower bed, or you really want to do a full garden/landscape renovation. The best way to be successful at any of these things is to get outside (or at least look out from behind a window in the A/C), take stock of what is already there, the space that is or might be available, research what plants or varieties might do well in your yard/garden (your local UF/IFAS Extension office is a great resource for this), and begin to sketch your ideas out. This planning step WILL save you time and money by ensuring you don’t purchase too many plants, by picking plants that will do well, and ensuring you install everything at the correct time.
So, take advantage of the heat, stay inside, and work up your garden gameplan together this August – fall is just around the corner. For help with soil testing, recommendations on plant varieties to purchase, or working up a garden/landscape plan tailored to you, contact your local UF/IFAS County Extension Office. Stay cool and happy gardening!
A mole cricket has a face only a mother could love. They are so strange looking, in fact, that in the past week I’ve had two people ask me what they were. They have large, round, helmet-like heads, undersized eyes, and massive front claws used for digging. Unlike your garden-variety crickets, which really don’t cause any major damage to home landscapes, the mole cricket is quite the turfgrass menace. Instead of hopping about aboveground, they tunnel beneath the lawn and feast on the roots and leaves of grass, often destroying entire yards. They are also vegetable pests, going after tomatoes, cabbage, and peppers.

Mole crickets spend most of their time below ground and form burrows for hiding, laying eggs, and traversing through their territory. In mating season, males create a monotone song that averages 88 decibels—as loud as a motorcycle! The call comes from their burrows, which have funnel-like openings that expand at the surface, creating amplification comparable to a horn.

The tawny mole cricket (Neoscapteriscus vicinus) is the most common to our area and is an invasive species from South America. UF IFAS has had a specific research program related to mole cricket management since the late 1970’s. One successful outcome of this program has been the introduction of a biological control species, the larra wasp (Larra bicolor). The wasp manages mole cricket populations by stinging and temporarily paralyzing crickets. A female will then deposit an egg into the mole cricket’s body. The cricket recovers and goes about its daily routine until the egg hatches, at which point the larval wasp feeds on and eventually kills the mole cricket. Along with the wasp and release of flies and a nematode that also manage mole crickets, the biocontrol methods introduced between the 1980’s and 2004 have resulted in a 95% reduction in mole cricket populations in north Florida.
If you are seeing mole crickets, you can attract larra wasps to your property by planting shrubby false buttonweed or partridge pea plants, which the wasps feed on. If you have serious damage from mole crickets, check out this thorough Mole Cricket Integrated Pest Management Guide, or contact the horticulture agent at your local county extension office to get a site-specific recommendation for management.
Trying to rejuvenate your flower beds can be challenging during these hot days and warm nights. This presents a chance to carefully select and plant varieties that not only endure but thrive in the scorching summer season. Luckily, Florida gardeners have many options, including bulbs. Bulbs are known for their ability to flourish and produce beautiful flowers year after year with proper care. Three of these, Aztec Lily, Walking Iris, and Spider Lily, can be planted during the month of August.
Aztec Lily.
AZTEC LILY
The Aztec Lily, a tender perennial bulb, belongs to the Sprekelia genus in the amaryllis family and is one of only three known species. Among them, Sprekelia formosissima stands out for its striking and showy flowers. Growing from 12 to 36 inches, Aztec Lillies are typically colored from scarlet to deep crimson, though there are also pink and white varieties available. Each bulb has the potential to produce multiple flower stalks annually, usually in sequence rather than all at once. The flowers exhibit bilateral symmetry, resembling the velvety appearance of an orchid. Aztec Lilies should be planted in full shade to part sun and can tolerate acidic and alkaline soil. These plants are incredibly versatile and well-suited for various landscaping purposes, such as mass planting, border decoration, adding accents to garden designs, and attracting butterflies to butterfly gardens.
Walking Iris.
WALKING IRIS
The Walking Iris, Neomarica spp., is a clumping herbaceous perennial, growing to a height of 18 to 36 inches. These plants boast attractive light green leaves and small Iris-like flowers that bloom periodically throughout the spring, summer, and fall seasons. Although the flowers have a short lifespan, they still add a delightful splash of color, making the Walking Iris an interesting addition to any landscape. The Walking Iris thrives in both full and partial shade, making it a versatile choice for your garden. While it can adapt to various soil types, it truly flourishes in moist areas. When grouped together in shady areas, the Walking Iris creates a lovely and eye-catching display. Its upright foliage, coupled with the occasional blooming flower, makes a bold statement in the overall landscape.
SPIDER LILY
Spider Lily.
Native to Florida, the Spider Lily (Hymenocallis latifolia) is a captivating perennial featuring alluring foliage and fragrant white blossoms. This clumping plant exhibits long, dark green leaves that emerge from an underground bulb, gracefully reaching a height of 24 to 36 inches. During the summer and fall seasons, the Spider Lily adorns itself with numerous white flowers, known for their enchanting fragrance, remarkable longevity, and delicate appearance. For optimal growth, place your Spider Lily in either full sun or part shade, and ensure the soil is well-drained. With its rapid growth, the spider lily serves as an excellent ground cover option, spreading its beauty across the landscape. Alternatively, it can be strategically planted in borders or highlighted as a specimen plant, adding charm and elegance to any garden or landscape design.
In the world of flora, the Aztec Lily, Walking Iris, and Spider Lily stand out as captivating gems worth exploring. Each possessing its unique allure and charm, these three species display nature’s diversity and ingenuity. For more information about summer bulbs, contact your local UF/IFAS Extension Office.
Bright color is sometimes hard to come by in landscapes, especially in those areas where not much likes to grow. In particularly sandy areas along our coastlines, it can be a challenge to find plants that can both tolerate extremely dry conditions with heavy salt spray and provide an aesthetic boost. Luckily, there is at least one flower out there that goes above and beyond when it comes to beauty.
Gaillardia pulchella, or blanket flower, Indian blanket flower, firewheel, or sundance is a relatively low growing (up to 1.5 feet tall) plant that favors conditions that would make most plants wither. It grows as an annual or short-lived perennial and though it goes dormant in the winter, during warm weather, it’s bright and colorful! It is native to the United States, but probably never spread farther east than Texas until assisted by humans. It grows well throughout Florida, and can often be seen along roadsides.

Spreading to around two feet wide, each individual plant may not blanket the ground, but it readily produces seed which is easy to germinate. Flowers are produced throughout the growing season. Varieties are available with different appearances, though all tend to be some combination of bright yellow and dusky red. The blossoms can be used as cut flowers, or left in the landscape to attract pollinators.
Blanket flower prefers well-drained soil, even growing out into beach dunes. As stated previously, it may be propagated easily by seed; either let dried seed heads remain on the plant long enough to drop seeds or harvest them to plant elsewhere. Sow seeds in the spring and enjoy low-maintenance color for months after!
