At the LSU AgCenter our goal is to assist our clientele in following an integrated pest management approach to insect control. Daily, we receive requests for control measures on a wide variety of home, lawn and garden pests. After taking the first step to identify the insect, your local extension agent may arrive at the conclusion that your bug is beneficial or does not warrant control.
A good example of this is the five-banded thynnid wasp. This long, slender wasp can be found hovering over lawns and flower beds across our state. The black and yellow color pattern on its abdomen is reminiscent of the yellow jacket or ground hornet, and this case of mistaken identity creates fear in homeowners or family members concerned about being stung or bitten.
Thynnid wasps are a common sight in the home landscape. Leaving this beneficial insect alone will help reduce June bug damage to lawns and trees.
However, the tynnid wasp is buzzing over lawns because it is trying to lay eggs on May beetle or June bug larvae. The white grubs eating the roots of your lawn grass are parasitized and killed by the thynnid wasp larvae. Although the female thynnid wasp can sting, she is not aggressive and poses little to no threat to humans or pets. The adult thynnids can be seen drinking nectar from flowers and, in rare cases, causing minor leaf injury to trees. The thynnid wasp larvae are actually preyed upon by velvet or cow killer ants, demonstrating the check-and-balance system nature uses to maintain an equilibrium in the landscape.

Louisiana blackberry lovers now have the option of enjoying their favorite fruit even later in the growing season. Primocane-bearing blackberries, also commonly referred to as fall-bearing/everbearing blackberries, are extending the harvest season for many southwest Louisiana blackberry growers. Primocane blackberries will produce multiple times on current-season canes compared to our traditionally grown floricane-bearing or summer-bearing blackberries that fruit on canes that must first overwinter before flowering.
In the northern United States, the range of blackberry production ends where temperatures dip below zero, killing overwintering canes. However, the advent of primocane blackberries has allowed these northern growers to produce blackberries like an annual crop. Even though blackberry canes freeze in the winter, the next spring they can be clipped to the ground. The new shoots of the primocane berries will fruit before the next winter’s freezing temperatures. In the South, primocane berries won’t freeze back each winter. Therefore, older canes can be removed after the fruiting cycle is complete. Primocane berries in south Louisiana almost produce like an ever-bearing crop. They will produce a main crop in the spring around late April and subsequent rounds of smaller cropping cycles until winter.
In southwest Louisiana blackberry growers are currently trialing primocane-fruiting blackberry varieties with promising results.
Prime-Ark Freedom bears the largest fruit of the
primocane blackberry types grown in South Louisiana.
Its thornless nature and lower propensity to sucker
makes it easy to manage in the home orchard.
Prime-Ark Freedom (thornless), Prime-Ark 45 (thorned) and Prime-Ark Traveler (thornless) are currently in production in our area. Freedom consistently produces the largest berry of the primocane types; however, the vigor of the plant seems to diminish with age. The thorny nature of Prime-Ark 45 and its proclivity to produce shoots away from the base of the plant makes management a little more difficult. Traveler seems to be the most balanced variety of the primocane types. Its upright growing pattern and thornless nature make it the easiest to manage.
Once primocane berries are planted and growth begins, canes should be tipped by breaking or clipping about an inch off of the terminal growth point when the plants reach a little over a foot in height. This tipping is important because it will encourage branching. A second round of tipping should be done when the plants near the 30-inch mark. Tipping will accelerate fruiting and yields while facilitating easier management and harvest conditions.

Growing a successful crop of spring strawberries in south Louisiana begins with the procurement of recommended varieties that should be replanted annually in the late fall. Unfortunately, due to a scarcity of plants and their perishable nature, finding plants is often a difficult task for the home gardener. Interested growers are encouraged to start lining up a plant source early. Your local extension agent can help direct you to potential transplant sources. Growers generally want to stick with June-bearing strawberry varieties, like Festival, Camino Real, Camarosa and Chandler. Plants are generally sold as bare-root transplants and are kept refrigerated until planting time.
Day neutral strawberries are also being planted on a limited basis in Louisiana. Varieties like San Andreas have been shown to produce extra-large berries and are not impacted by day length conditions.
Most strawberry plants sold in Louisiana are produced in northern California. By the time they arrive in Louisiana in October they have already received some chilling in the higher elevations where they were grown. This allows the transplants to bloom shortly after transplanting. This precocious production is of great benefit to commercial strawberry producers in Louisiana who are prepared to cover blooming plants and protect them from freezing temperatures in the hopes of producing a high-value winter crop of berries. The home strawberry grower, on the other hand, is generally more willing to forgo winter production and instead focus on the easier-to-manage spring crop that generally can be produced without frost protection.
Growers should try to have planting completed before mid-November or yield losses will generally occur.

The Jolt series dianthus is a hybrid (Dianthus barbatus Jolt) cool-season annual for Louisiana. It is an interspecific series that has three showy colors to choose from: cherry, pink and pink magic. In Louisiana, it is best to plant these in the fall for beautiful winter color or in the very early spring for color through May, and if you’re lucky it may last year-round. This dianthus is said to be more heat tolerant than some other types of dianthus and holds up better to Louisiana heat.
Jolt dianthus prefers an enriched, well-drained soil and blooms best in a full- to partial-sun locations. It makes gorgeous showy flowers. Jolt has a continual bloom without setting seed. It is a very durable plant that can withstand hotter temperature conditions and has few disease issues. This dianthus is well-branched and easy to produce. It has dark green leaves on shorter, more compact plants compared to the Amazon dianthus. Jolt grows to 16 to 24 inches in height and 12 to 14 inches in width. Its growth habit is tall and rounded and is especially attractive to butterflies, bees and other pollinators.
The colors Jolt Pink, Pink Magic and a darker red color called Jolt Cherry all have clusters of flowers on well-branched stems. To encourage continuous blooming, deadhead or trim the faded flowers.
These flowers will look great paired with other summer favorites still blooming into the fall. To name a few, black-eyed Susan, bee balm, zinnias, marigolds, cassias, angels trumpet, butterfly bush, firecracker plant, firebush, Mexican Heather and vincas. In your landscape, make a statement by installing a mass planting, use it as a border, place in containers as a filler or thriller plant or use them for cut flowers. If you plant it in the middle of a bed, add more compact plants in front to create a full, flowery look.
In addition to the Jolt series dianthus, there are several plants found blooming in the summertime that will carry over into the fall in Louisiana, including butterfly bush, firebush, Turk’s cap, cassia plant, angel’s trumpet, salvias and sedums. You can also continue to plant marigolds and zinnias for a great fall-flowering bedding plant.
It is also likely in the fall that many of your warm-season bedding plants, such as periwinkle, blue daze, purslane, scaevola, impatiens and begonias as still going strong. If that’s the case, leave the beds alone for as long as you can enjoy the display. Once the cooler temperatures settle in, it will be time to convert beds to cool-season plants.
If you don’t already have some of these plants in your landscape, container plants can still be transplanted so that you may enjoy these gorgeous fall bloomers. There are some great fall-blooming perennials out there for you to try.
One of my favorites is the firebush (Hamelia sp.). Lime Sizzler firebush (Hamelia patens Grelmsiz) is a Louisiana Super Plant. It can be found in most local nurseries. The hummingbirds just love this plant! It has gorgeous orange and red flowers on a yellow-green variegated foliage. This shrub will bloom best in full sun to partial shade and it will add quite the sizzle to your landscape.
Turk’s cap (Malvaviscus drummondii) is another great bloomer for the fall. A native plant of North America, it is a root-hardy perennial but may grow year-round in protected areas. Otherwise, it will come back from its roots in the spring. This plant grows well in full sun to partial sun and has striking red flowers that never truly unfurl. Bees, butterflies and hummingbirds just love this flower, too! Dark green foliage makes it another striking selection for your landscape beds.
Cassias always come to mind when I think of fall bloomers. The gorgeous yellow flower clusters typically bloom between September and November in Louisiana, having a two- to three-week bloom time.
There are a few different cassias commonly grown here. Cassia splendida, and other cassias commonly known as the candlestick plant or tree, Cassia corymbosa and Cassia alata. You may also see popcorn cassia, Cassia didymobotrya, being sold and grown in Louisiana. All the cassias tend to be medium-to-large herbaceous, and sometimes woody, shrubs. They are easy care plants with few pest and disease problems. They grow best in full to partial sun and are another favorite of pollinators.
Salvias are another great choice for fall flowering plants. Salvia guaranitica varieties Black and Blue and Argentine Skies, start flowering in summer and save their best bloom for the fall. Some fall blooming salvias are rosebud sage (Salvia involucrata) and forsythia sage (S. madrensis). Rosebud sage tend to be very large, growing 5 to 7 feet and should be planted behind smaller growing plant in the landscape. Forsythia sage is much smaller. They both grow well in full sun to partial shade, and, you guessed it, are also great flowers for pollinators including bees, butterflies and hummingbirds.
Angel’s trumpet is another fantastic fall-flowering plant. It is a tropical plant that will freeze in the wintertime when temperatures drop low enough but will come back from the roots each spring and have showy bugle-shaped flowers in later summer through the fall. A truly gorgeous addition to the landscape, it comes in all shades of color, including yellow, pink, white, purple and orange to name a few. The hummingbirds love this plant, too.
There are some sedums that bloom in the fall. One example is Autumn Joy, Hylotelephium Herbstsfreude. It has succulent leaves and stems with showy clusters of rosy or copper to brown flowers that are just gorgeous for the fall. They typically bloom in early summer and again in the fall and they perform best in full sun and can tolerate some drought and heat once established.
Marigolds and zinnias are another great blooming bedding plant for the fall. You can plant both now and enjoy until freezing temperatures hit.
Marigolds come in a wide range of varieties. The African marigolds are taller, larger, and can be used as a cut flower. We all recognize the fall primary colors of orange, gold and yellow. The French marigolds are the shorter variety, with smaller-flowers types that display more color variations.
Many zinnia species are also available. Traditional, older zinnia varieties are the Zinnia elegans. Some of these varieties are good for cut flowers, like the Benary’s Giant series. Other varieties are better as short bedding plants, such as the Dreamland series. A wide range of flower colors is available in zinnias.
Both zinnias and marigolds are easy care and profuse bloomers that love full sun to partial shade, and the pollinators love these flowers just as much as we do! Remove faded flowers to encourage new blooms.
And last, but certainly not least, are chrysanthemums. They have become synonymous with fall by sporting all the gorgeous fall colors. They can be used for fall decorating for Halloween or Thanksgiving gatherings and grow well in containers but can also be grown in the landscape in areas that get full to partial sun.

Trees do best when planted in the fall.
Yellow marigolds are a great fall-blooming bedding plant.
Plant herbs such as rosemary in the fall.
Fall is a great time to plant! Plant bedding plants, trees, shrubs, ground covers, vines, fall vegetables and fruit trees.
Take soil samples from landscape beds and submit them to the LSU AgCenter Soil Testing and Plant Analysis Laboratory for analysis. Check with your parish LSU AgCenter extension office for more information.
Prepare beds and amend your garden soil if your soil test indicates any insufficiencies.
Enjoy fall-blooming plants. Many spring- and summer-blooming plants will carry over into the fall. This is a great time to enjoy these or transplant new containers to your landscapes. You can plant fall-blooming annuals and perennials, including cassias, butterfly bush, firebush, angels trumpet, marigolds, zinnias, Turk’s cap, salvias and sedums. Many warm-season bedding plants, such as periwinkle, blue daze, purslane, scaevola, impatiens and begonias, are still going strong. Leave the beds alone for as long as you can enjoy the display. Once the cooler temperatures settle in, it will be time to convert beds to cool-season plants.
Fall is an excellent time to plant many herbs in the garden. A few herb plants provide a lot of harvest, so don’t plant more than you can use. Herbs to plant now include parsley, sage, thyme, dill, cilantro, rosemary, oregano, borage, fennel, nasturtium, French tarragon, chives, mint and catnip.
Plant spring-flowering bulbs in your gardens from late October through early December. Exceptions are tulips and hyacinths, which must be refrigerated and planted in late December or early January.
Garden mums make a great addition for fall color. Check at your local retail garden center for availability.
Watch azalea plantings for early fall infestations of lace bugs. Control with acephate, horticultural oil sprays (bifenthrin, cyfluthrin or permethrin) and other recommended insecticides.
Build a compost pile out of leaves, grass clippings and remains from your vegetable garden.
September is a good time to divide and transplant Louisiana irises. Fertilize your irises in October.
Many of the summer-blooming perennials are finished or finishing up their floral display for the year. Cut back the flower stalks and old, faded flowers to keep the plants looking attractive.
October weather can be dry. Water plantings as needed. Pay special attention to any newly planted areas. It generally is best to water direct-seeded beds of flowers or vegetables lightly every day to make sure the seeds do not dry out.
Prune ever-blooming roses by early September.
Enjoy the fall color in trees such as bald cypress, Nuttall oak, Shumard oak, cherry bark oak, flowering pear, Chinese pistachio, ginkgo, Japanese maple, sweetgum, sumac, red maple, Southern sugar maple and hickory. Plant some if you don’t already have them in your landscape.
Dr. Heather Kirk-Ballard
There is a lot to “fall for” in the fall vegetable garden. First, fall in love with the idea that temperatures have slightly fallen. Insect and disease pressure have also slightly fallen. And, finally, the leaves are falling! Why leaves, you ask? Because they absolutely make the best mulch for the garden — free and plentiful. Don’t want to rake yours? Plenty of neighbors will have their leaves bagged and curbside … just get there before the other garden scavengers do. So, grab a cup of tea, soda, coffee or water and fall into the garden advice in the rest of this article.
Lots of crops can be planted in the next few months. Before planting, ask yourself:
This sounds like a whole lot of preparation, but trust me, the more you do now, and the easier it will be to manage the garden over the next few months.
Broccoli (T), Brussels sprouts (T), cabbage (T), Chinese cabbage (T), cauliflower (T), collards (T or S), endive, carrots, English peas, snow peas, garlic, kohlrabi (T), lettuce (S or T), mustard, onions (seeds late September for transplant in December), parsley (T)*, snap beans*, radishes, rutabagas, shallots, spinach, strawberry bare root plants (late September), Swiss chard (S or T), turnips and kale.
Cabbage (T), beets, broccoli (T), mustard, turnips, collards, kale, parsley, shallots, radish, beets, spinach, leaf lettuce, Chinese cabbage (T)*, celery, onions (seeds early to mid-October for transplanting in December), Swiss chard, strawberry bare root plants, garlic*, carrots and endive*.
Beets*, shallots, Swiss chard (T), spinach*, kale, radishes, mustard, carrots and turnips.
*Plant during the first part of the month. (T) = Transplant (S or T) = seeds or transplants. If nothing is noted after the crop, plant by seed.
Spacing of fall crops is critical. Broccoli and cabbage can be double-drilled on 12-inch centers, but widen that space to 24 inches between plants for cauliflower and single drill. Carrots and radishes can be scattered in the garden or planted in up to four drills if your rows are wide enough. Space both carrots and radishes 1 inch apart or thin as they grow for nicely shaped roots. Hint: Carrots often need light to germinate. Scatter seeds, then water them in. Do not bury them. Carrots do a lot better in loose soils. Make sure you have turned yours over even if you are growing in pots. Make that soil loose! Mustards, collards, kale and leaf lettuce can also be directly seeded but should be thinned to 4 to 6 inches between plants. If you want bigger kale and lettuce bunches, then plant them every 12 inches on double drills. Turnips and beets can be directly seeded and thinned as they grow to 3 to 6 inches apart depending on how big you want the final product. Now for the giants! Artichokes, space plants 4 feet apart … just trust me, it is necessary. Many gardeners get excited, I can’t blame them, but we often try and cram too many plants into our smaller gardens. This is setting yourself up for disaster.
The plants will compete for light, water and nutrients. Plus, insects will love all the tight niches you’ve created. Correct spacing takes a garden from good to excellent!
Remember those falling leaves? Take every last one of them and put them in the garden. For large gardens, leaves belong in the row middles where you walk. In raised beds, mulch the entire top of the garden with leaves. Place them in your pots, too! The leaves should be 3 to 5 inches deep. This will conserve water, block sunlight-reducing weed germination and help you walk in the garden after a major rain.
Irrigation is critical the first two weeks after planting (especially direct-seeded crops) and throughout the growing season. One inch of rainfall or irrigation is adequate.
Check the garden at least once a week. Be on the lookout for worms, caterpillars and stink bugs in gardens planted in early September. All of these will wreak havoc on your newly planted crops. I like waiting until late September or even into October, when this pressure is lowered. But you’ll still need to be on the lookout for aphids. They have a way of making themselves at home in the fall. Thrips love shallots and green onions. And snails and slugs love strawberries. These are the biggest fall garden culprits. Disease will be present but reduced. The biggest culprits are anthracnose and black rot. When purchasing transplants, look out for tiny worms. Moths love laying their babies on broccoli, cabbage and cauliflower transplants early in the season. They can find these plants anywhere. Also, look for aphids on transplants. Make sure you are purchasing clean plants.
Herbs are a great addition to the fall vegetable garden. Fall herbs include dill, cilantro, borage and parsley. Mint and rosemary can be planted too.
Finally, to really “fall” in love with your vegetable garden, make it a comfortable space. The garden should be worked in and relaxed in. The temperatures are lower, so spend a little time out there. Add a bench or small table and chairs. Consider decorating the garden with fun ceramic plant labels. Add a bit of whimsy with a gazing ball, arbor or any yard art. Then “fall” back and relax.

Louisiana usually stays warm well into the fall, and lawns continue to grow until nighttime temperatures dip into the 50s. So, be sure to mow and water your lawn, as needed, to keep it healthy.
More than likely, however, it is time to put up your fertilizer spreader. Fertilizing warm-season grasses during the fall with high nitrogen (summer-type) fertilizers or winterizing fertilizers containing high levels of nitrogen are not recommended for Deep South lawns.
Stimulating fall growth of St. Augustinegrass, centipedegrass and zoysia with nitrogen leads to increased large (brown) patch disease and winter kill. Bermudagrass may be fertilized into September, but I would not make any more applications of high-percentage nitrogen-containing fertilizers after late August on St. Augustinegrass, centipedegrass or zoysia.
If you would like to extend the green color in home lawns this fall, apply foliar iron spray or spreadable iron granules. This will give you a nice flush of green color without increased growth.
I’m sure that you have heard of winterizer fertilizers. Potassium (the last number in the analysis on fertilizer bag) is actually the nutrient associated with winter hardiness and increased disease resistance with turfgrass. There is definitely an advantage to having the correct amount of potassium in the soil. Get a soil test before applying high-potassium fertilizer, however, because there is no advantage to applying excessive amounts of this nutrient. If a soil test indicates that potash is lacking, choose a potassium-containing fertilizer with zero or a very low percentage of nitrogen (the first number on a fertilizer bag) during the late summer or early fall because we are not trying to stimulate growth for the reasons discussed above. If a soil test calls for adding potassium, you can apply during September while temperatures are still warm, and the lawn is still growing. Very slow growth occurs as day lengths get shorter by late September and October.
An important fact to consider if you bag your lawn clippings: The removal of grass clippings from lawns can severely deplete the soil of potassium. Grass leaves and stems contain very high levels of potassium. Keep in mind that when a lawn is mowed appropriately, it is better to leave clippings to decompose on the lawn as a good source of turf nutrients, including potassium. Clippings from a lawn that is mowed regularly have only a small role in the overall buildup of thatch in turfgrass.
Fall is the best time of the year to get your soil tested by the LSU AgCenter Soil Testing and Plant Analysis Laboratory.
Soil testing really is the first step to a beautiful lawn next spring and is the best way to determine exactly what your lawn needs to become thick and healthy. If you haven’t tested your soil in the past several years, do it now.
To test your soil, submit a pint of soil to the LSU AgCenter extension office in your parish. The pint should be a composite of soil samples collected from several different areas in the lawn. You only need to go about 4 inches deep. Also, to simplify the soil sampling and submission process, there are pre-addressed submission boxes with sampling instructions at several garden centers throughout the state. There is a small fee for testing.
The sample results will be sent to your home mailbox and email in less than two weeks. An LSU AgCenter extension agent can help you interpret the results from the soil sample. The sample results may indicate that lime is needed to increase soil pH. If so, fall and winter are good times to apply lime because it takes several months to activate in the soil. Elemental sulfur may be recommended to reduce soil pH in alkaline soils.
If your lawn was full of winter weeds last spring, this fall is your first opportunity to reduce infestations with pre-emergence herbicides. Pre-emergence herbicides, such as prodiamine, pendimethalin, dithiopyr, isoxaben and indaziflam, may be applied in September to help manage the first flush of winter weeds, like annual bluegrass, chickweed and lawn burweed. Consider reapplication in early November. These herbicides work prior to the emergence of the weeds, so timing the application before the weeds germinate is critical. Atrazine can be applied on most southern lawns in October with the exception of bermudagrass. Atrazine could be applied on bermudagrass after the bermudagrass is dormant.

Apples (Malus domestica) are a member of the Rosaceae family and known to have originated in central Asia. They are grown worldwide, and the U.S. ranks No. 2 in apple production in the world after China. Usually, apples are grown in colder climates because of their requirement of a minimum number of cold hours between 32 and 45 degrees Fahrenheit during winter (the chilling requirement), after which they bloom in spring. However, varieties of apples, including Anna, Dorset Gold, Ein Shemer, and Ozark Gold, a variety suited for north Louisiana, may perform well under Louisiana’s mild winter weather.
There are several fungal and bacterial pathogens that can cause diseases on both trees and fruits; however, three fungal diseases, including black rot, white rot and bitter rot are commonly known to occur on fruits. Of these three diseases, bitter rot is the most destructive and can result in significant yield loss in commercial production. All stages of fruit development are susceptible to fungal infection, but most infection occurs during midseason as the fruit approaches maturity. The symptoms first appear as small, circular brown flecks on the surface of fruits (Figure 1). As the disease progresses, slightly sunken, soft, watery, and light to dark-brown lesions develop (Figure 2). Later, fungal fruiting bodies are produced in concentric rings on the lesions (Figure 3). During wet weather, large quantities of spores (conidia) in salmon-colored masses are produced from these fruiting bodies and result in secondary infection. The tissue subsequently rots, and the fruits shrivel into a mummified state.
Bitter rot of apple is a fungal disease commonly caused by two species known as Colletotrichum gloesporioides and C. acutatum. Both fungal species overwinter in mummified fruit and in dead wood and cankers. Spores are primarily dispersed by splashing water or rain. Infection may occur within five hours at an optimal temperature of 80 degrees Fahrenheit. Disease develops rapidly under warm, moist conditions.
Management of bitter rot in both commercial and home garden apple production requires an integrated pest management approach. Cultural management practices that reduce disease in home gardens and orchards play an important role in combatting bitter rot. Growers and homeowners must practice good sanitation practices, including removal of mummified fruits from trees and the ground, pruning dead branches and twigs, and removal of older and current season fire blight-infected branches to avoid fungal infection. If feasible, burn the pruned and diseased tissue or discard it properly. Removal of diseased fruits during growing season is essential to reduce disease spread. Growers should follow regular pruning and a proper fertilization program to improve tree health. In home gardens, use of the cultural practices mentioned above is the most effective way to manage the disease. Preventative fungicides used in conjunction with good sanitation practices are beneficial in managing the disease in commercial production. Several fungicides are available for commercial apple production, and growers are encouraged to follow the apple spray schedule recommended in the LSU AgCenter Plant Disease Management Guide, publication No. 1802.
