This is an excerpt from a longer publication found here

Weed control in irises can be difficult. Fortunately, many annual broadleaf and grassy weeds can be easily controlled with mulches and the judicious use of herbicides.

Mulch is helpful in preventing weed growth, but it should be used sparingly (no greater than a 2-inch layer in irises) to avoid disease problems.

The preemergent herbicides in the following table are labeled to control a large spectrum of broadleaf and grass weeds in irises.

Barricade and RegalKade (Granular) prodiamine
Dimension dithiopyr
Gallery isoxaben
Freehand dimethenamid and pendimethalin
Pendulum, Corral (Granular) pendimethalin
Pennant metolachlor
Snapshot (Granular) isoxaben and trifluralin
Surflan oryzalin
Treflan and Preen trifluralin
XL (Amaze) benefin and oryzalin
  • Most preemergence herbicides listed are available in both a granular and sprayable form. Granular herbicides are popular because they require no mixing and are more forgiving when an application error is made.
  • Most herbicides or herbicide combinations will control 80 to 95 percent of the annual weeds normally found in irises. Many weeds not controlled with preemergent herbicides can be removed by hand.
  • The herbicides listed are designed to control weeds germinating from seed not weeds coming from vegetative structures (tubers, rhizomes, etc.).
  • During iris establishment, and under heavy weed infestation, at least two herbicide applications should be made in most Southern states — usually in January / February and again in April /May — to control most spring and summer weeds.
  • Additional preemergence herbicide applications may be necessary to control annual winter weeds. Preemergence herbicides tend to be more useful on large acreages.

Several postemergence grass herbicides are labeled for use in irises.

Acclaim Extra fenoxaprop
Envoy Plus clethodim
Fusilade II, Ornamec, and Grass-B-Gon fluazifop
Segment sethoxydim
  • Postemergence grass herbicides are mixed with water and sprayed over the top of irises to control grasses that are actively growing.
  • These grass herbicides have no preemergent activity and will not prevent the germination of weed seeds.
  • Herbicide labeling can change, so always read and understand the label before using any pesticide.
  • As herbicides go off patent, some manufacturers market herbicides under different trade names, so the buyer must beware. For instance, glyphosate, the active ingredient in Roundup®, is now available from many suppliers under a wide range of trade names and formulations.

Herbicides containing the active ingredient glyphosate can be used to control problem perennial weeds that are unsuccessfully controlled by hand removal or mulches. Weeds growing among irises should first be carefully separated from iris leaves and then placed horizontally on bare ground or a piece of plastic for treatment. Next, paint or sponge a 5 percent solution of glyphosate (6 ounces of at least a 41 percent glyphosate concentrate per 128 ounces of water). A cover, such as a plastic bag, placed over the iris plant while treating the weeds will help shield the iris from the herbicide. Remove protective coverings once the herbicide has dried. The treated weeds will begin to die in 10 to 14 days. If weeds re-sprout, repeat the treatment procedure.

Broadleaf and other perennial weeds can be difficult to control in iris. Nutsedge (Cyperus spp.) and Florida betony (Stachys floridana), for instance, are two problem weeds with no labeled selective herbicides available to control them in iris.

The University of Georgia has conducted experiments with both 2,4-D (various trade names) for controlling select broadleaf weeds and halosulfuron (Sedgehammer® and Prosedge®) for controlling nutsedge. Neither product is labeled for weed control in Iris, but data has indicated labeled rates of these postemergence herbicides can be used on select Iris cultivars with little to no damage. It is suggested that users wishing to try this method test it on small areas of iris / weeds to be treated. Wait two weeks and then evaluate the iris plants for unacceptable damage before treating an entire area.

Always read the product label and contact your local County Extension office with any pesticide or plant culture questions.

John Ruter, Director of The Trial Gardens at the University of Georgia and Professor of Horticulture at UGA

See original article with photos here.

Each summer the staff of The Trial Gardens at UGA selects an all-star team of plants that performed spectacularly well during the growing season.

“These Classic City Award winners are the very best plants in the trial gardens, based on year-round performance and/or eye-clutching beauty,” said John Ruter, University of Georgia horticulture professor and the gardens’ director. “We raise thousands of plants each year, and these are the best of the best.”

Since 1982, The Trial Gardens at UGA have been used as a literal testing ground for plants from around the world. By evaluating new selections of annuals and perennials, the Trial Gardens’ staff helps introduce new plants to the Southeast’s green industry and the general public.

The Trial Gardens’ plant evaluations are respected across the globe. Commercial nurseries depend on the staff’s recommendations to determine what they will grow for sale the following season.

Many of the Classic City Award-winning plants are available for sale now, but others will be available through nurseries next season. Gardeners should ask their local nurseries to stock them.

2014 Classic City Award Winners (Commentary provided by trial supervisor Meg Green and gardens’ director John Ruter)

  • ‘Archangel Dark Rose’ Angelonia– Ball FloraPlant “This Angelonia stood out amongst the others. It started out early by out-blooming its competitors and has remained strong through the hottest temperatures. The plants are compact and sturdy.”
  • Calibrachoa ‘Superbells® Frostfire’ “Our Calibrachoas were a bit slow to bloom in early summer, however, once the flowering began, it was profuse. ‘Superbells Frostfire’ has outshone other Calibrachoas, producing countless white flowers with a yellow eye. These plants remained compact while other Calibrachoas became spindly and scraggly late in the summer.”
  • Catharanthus Cora™ Series “We had 14 colors of the Cora series of Catharanthus this summer and every one of them performed outstandingly. The plants were consistent in height and floriferousness. All tolerated the heat, humidity and irregular rains quite well.”
  • Coreopsis ‘Sunshine Suzie’ “‘Sunshine Suzie’ is not a loud plant that begs for attention, but more of a quiet surprise. The plants were compact but airy, and were constantly in nickel-sized, yellow flowers. Month after month, ‘Sunshine Suzie’ excelled in our climate.”
  • Echinacea ‘Sombrero™ Adobe Orange’ “‘Sombrero Adobe Orange’ has completely wowed us with its extraordinary beauty. The plants produced numerous large, bright orange, cone-shaped flowers. This cultivar bloomed longer than any Echinacea we have grown ever.”
  • Euphorbia ‘Star Dust Super Flash’ “Over the years, the Euphorbias have performed well in our garden. ‘Star Dust Super Flash’ outperformed the others this summer. Countless small, white flowers covered the compact plants from April through October. The plants were well behaved, not falling over, nor infringing on their neighbors.”
  • Impatiens Bounce Pink Flame “This year was a great one for our New Guinea Impatiens. So many cultivars performed extraordinarily well, including the series ‘Big Bounce’ and ‘Bounce.’ In particular, ‘Bounce Pink Flame’ grew tall, but never lodged (or bent).”
  • Heliopsis ‘Sunstruck’ “‘Sunstruck’ Heliopsis grew to a mere 6 inches in height. Its leaves are variegated and they accentuate the large, yellow flowers well. These plants withstood our heat and humidity and performed beautifully.”
  • Hibiscus ‘Royal Gems’ “‘Royal Gems’ Hibiscus has been in our garden for several years and it has impressed us this long. The plants resist the insects that decimate many other Hibiscuses. ‘Royal Gems’ produces giant, deep rosy-pink blossoms for several weeks throughout summer. Its foliage remains a healthy, lush green until frost.”
  • Lobularia ‘Bicolor Pink Stream™’ “Month after month, ‘Bicolor Pink Stream’ displayed its beauty and perfumed its environment, never surrendering to the Georgia heat. This Alyssum is truly an extraordinary cultivar.”
  • Pelargonium ‘Glitterati™ Ice Queen’ “‘Glitterati™ Ice Queen’ was grown in hanging baskets in our garden where they thrived in the hot, blazing sun. The variegated leaves did not brown in the sun, but remained healthy all summer. This geranium produced numerous orange-red blooms that were evenly distributed throughout the plants, thus creating a lovely, mounding appearance.”
  • Petunia ‘Supertunia® Morning Glory Charm’ “Petunia ‘Supertunia Morning Glory Charm’ performed perfectly through the hot summer. It quickly formed a mound of small, violet blooms with a large, white eye. This petunia was loaded with so many small blooms, even in the hottest months of the summer. It never ceased to be a perfect sphere of violet with only bits of green visible.”
  • Scaevola ‘Scalora Amethyst’ “This fan flower amazed us with its perfection throughout the summer. ‘Scalora Amethyst’ was another cultivar that was obviously a winner from early in the summer. The plants easily grew into a mat of blue blooms atop its foliage.”

Why do these lantana have injured leaves and no blooms?

Lantana Lace Bugs Can Stop Bloom!

Why do these lantana have injured leaves and no blooms?
Lantana lacebug injury, Chazz Hesselein, Alabama Cooperative Extension, Bugwood.org

Lantanas can bloom from June through early October in Georgia. Lantana lace bug can stop blooming in the summer leaving green plants with no blooms. The lantana lace bug is a small brown insect up to 1/6 inch long. Adult lace bugs are long, oval insects with a midsection that is slightly wider than the ends. The rear of the lantana lace bug is blunt but rounded off. The young are dull-colored and spiny. Look for the lantana lace bug by shaking the branch over a piece of white paper or light-colored cloth.

Lace bugs feed on the bottom of the leaves and on young flower buds.  They make the top of the leaves speckled with white, similar to mite injury. Underneath the leaf you may see brown, tarry spots that are the insect’s droppings. Since lace bugs feed on young flower buds, lantana bloom may be severely reduced or stopped completely. When populations are very high, the lantana leaves may turn almost white and fall from the plant.

Cultural Control:

Lace bugs do have several natural enemies that help to control their numbers – spiders, lacewing larvae, assassin bugs and predaceous mites. Be careful using pesticides to preserve these natural enemies of the lantana lace bug.

Planting less susceptible varieties of lantana may help reduce lace bug numbers though this may not completely control lace bugs:

Lantana that are less susceptible to lantana lace bug:

  • Weeping White, White Lightning, Weeping Lavender, Imperial Purple, Patriot Rainbow, Denholm Dwarf White, Radiation, Dallas Red, Gold Mound, New Gold and Lemon Swirl
  • Cultivars of Lantana montevidensis
  • Small leafed varieties seem to be less susceptible than large leafed varieties, although both types can be attacked by lantana lace bugs.
Why do these lantana have injured leaves and no blooms?
Lantana lacebug adult, Forest and Kim Starr, Starr Environmental, Bugwood.org

Lantana that are more susceptible to lantana lace bug:

  • Patriot Desert Sunset, Pink Frolic and Patriot Sunburst

If cultural and natural controls do not limit the lace bug population, you may need to treat with chemicals.

Chemical Control:

See the UGA Pest Management Handbook for pesticide recommendations. Read and follow all label directions when using pesticides. This is especially important now since some pesticide labels have changed.

Check the plants in two weeks after the first treatment and treat again if needed.  Once you control the lace bugs, the blooms should slowly return if temperatures are warm enough and other growing conditions are good.

Other problems that affect bloom:

Blooming on lantana should slow down as temperatures drop in the fall.  Lantanas like full sun, well drained soils, deep watering once a week and light fertilization. If the plant is lacking one of these, correct the problem.

To improve bloom, you can prune off old seed pods or berries left from prior flowers.  Then, fertilize again lightly and water deeply once a week to encourage new blooms. Take care not to over fertilize since this may reduce flowering and increase disease susceptibility.

UGA experts share deer control tips

“When it comes to wildlife damage in landscapes and agricultural plantings, the most common problem is deer feeding and browsing damage — especially in the winter and early spring,” said Paul Pugliese, a University of Georgia Extension agent in Bartow County.

A hungry deer in the winter will eat just about any vegetation and can easily consume four pounds or more of plant material each day, he said.

Plant prickly plants

To help keep Bambi and his buddies from destroying landscape plants, UGA Extension home vegetable horticulturist Bob Westerfield suggests planting varieties that are harder to swallow, literally.

“Tougher plants like hollies and junipers are usually less desirable to deer,” he said. “I’m not saying they won’t eat them, but the prickly leaves make it more difficult.”

Westerfield says plants like hostas, pansies and fleshy succulents are “like ice cream” to deer.

(A publication with a complete list of deer tolerant ornamental plants can be found on the UGA Extension publication website.)

Change odor repellents frequently

Odor repellents can also be used to keep deer at bay, but Pugliese and Westerfield both view them as temporary fixes.

“Odor repellents … wear off when it rains,” Pugliese said. “If used, they should be applied at least once a month, or after every rainfall, from early fall until late winter. If you miss a timely application, the end result will be deer damage.”

If food is extremely scarce, he has seen deer ignore the repellents despite the taste or odor. “Deer don’t develop resistance to repellents, but they do get use to them,” he said.

Preventatives like garlic sticks and sprays will work longer if rotated, Westerfield added. On his farm in Pike County, he hung garlic sticks in his pear tree to keep deer from eating all the fruit. “What I discovered is the deer must like garlic-flavored pears,” he said.

Mesh or electric fences

Personally, Westerfield recommends building a fence to block deer from vegetable gardens. Home garden centers sell what Westerfield calls “a thin version” of deer fencing. He orders 7 ft. tall heavy gauge deer fencing online.

Deer recently chewed a hole through this. “The next level for our farm will be an electric fence. Electricity will be the first welcome to our garden from now on,” said a clearly frustrated Westerfield.

Todd Hurt, training coordinator for the UGA Center for Urban Agriculture, was so frustrated by deer destroying his landscape that he bought a Scarecrow Sprinkler. The device’s manufacturer claims a blast of water from the motion activated sprinkler will “scare animals away, teaching them to avoid the area in the future.”

“It seemed to work. It got me every time I would forget about it,” Hurt said. “It needs a constant supply of water pressure so I had to connect it to PVC pipe instead of a water hose because the hose will swell or burst. And, it was pretty strong and would move on the stake so the stake needs extra support.”

UGA Trial Garden in Athens


The Gardens at Athens were started in 1982, when Allan Armitage and Michael Dirr, along with a number of students, plowed some ground and built a wobbly lathe area. Today, we evaluate plants or seeds from almost all the plant breeding companies in the world, along with material from perennial plant nurseries, individual growers and gardeners, as well as material from Dr. John Ruter’s breeding program.

Trial gardensThe Gardens at UGA serves research and teaching functions and is an important resource for breeders, retailers, growers, landscapers, and consumers. Our open houses provide opportunities for gardeners, breeders and growers to view the trials. We enjoy visits by plant breeders and representatives of many of the major international horticultural firms who want first-hand data to produce better cultivars for the expanding southern market.

The Gardens are open year-round and are located between Snelling Dining Hall and the Pharmacy building on the UGA campus. The garden is open to the public and professionals alike and detailed information on the plants we trial is available to all by visiting Garden Trials.

The trials are planted in April and May and consist of major and minor bedding classes, tropicals, vines, plantings of specialty annuals, over 150 free-standing containers, ~180 rose cultivars, numerous hanging baskets and three large perennial beds.

How Plants are Evaluated

Annuals Every two weeks, every cultivar is evaluated by Meg Green (Trial Garden Supervisor) for “horticultural” performance. This allows us to follow the performance of each cultivar through “good times and bad.” The data are combined into a single performance rating, based on a scale of 1-5, with 5 being exceptional, 1 being almost dead. The ratings are then used to generate a graph of performance over time, and are updated at every evaluation date. This allows a real time viewing of performance and more importantly, an in-depth understanding of how a plant performed from spring to fall. Most cultivars will be accompanied by a photo. These graphs can be found under annuals.

The Best of the Bunch

trial gardens 2For annuals, we also select the best cultivars for each genus and list them under ‘Best of the Best‘. For both annuals and perennials, we also choose the recipients for the Classic City Award; the very best plants in the garden over the entire season, well worth a place in any landscape.

During the evaluations, there is also a weekly list of Plants of Distinction (10 plants that are good that week). This allows growers and landscapers to easily identify plants that perform well during given times of the year.

UGA Department of Horticulture professor John Ruter took over as Director of the Trial Gardens from garden co-founder Allan Armitage on July 1, 2013. For more complete information, the Trial Gardens have an excellent web site.

UGA Department of Horticulture professor John Ruter took over the day-to-day operations from garden co-founder Allan Armitage on July 1. Armitage is officially retiring at the end of 2013. He originally retired in 2010 and came back halftime.

Ruter has spent more than two decades as a horticulture professor and a nursery crop research and Extension specialist on the UGA Tifton campus, where he also ran the Coastal Plain Research Arboretum.

He moved to the Athens campus in 2012 after he was awarded the Allan M. Armitage Endowed Professorship for Herbaceous Plant Instruction and Introduction. He now teaches classes in plant identification and environmental issues in horticulture.

Ruter doesn’t want to rustle too many leaves as he eases into his new role, but he does want to spruce up the garden a bit — mostly planning changes to attract new visitors, allow it to run more efficiently and be used for more horticulture classes.

“I’m just starting with it, but I do have lots of ideas,” Ruter said.

While the Trial Gardens serves as a testing ground for new plant varieties, it’s also an integral part of the UGA Department of Horticulture’s teaching and research programs. It’s important to Ruter to maintain all the facets of the garden’s mandate.

Plant nurseries and breeding companies send hundreds of new plants each year to see if they can survive the hot and rainfall variable Southeast. They fund the garden by paying to have their plants evaluated by an outside source. That money pays for the gardens’ upkeep and a team of student workers who keep the garden running.

While providing an important link with the green industry, the garden is also a research lab, where Ruter will work with graduate students to develop new plant varieties, and a classroom for plant identification and other horticulture courses.

Ruter plans to make the garden more useful as a teaching tool by planting more perennials and annuals that bloom in fall and early spring when classes are in session. This will also be good for the entomology, plant biology, plant pathology, landscape architecture and visual arts instructors who also use the garden as an outdoor classroom.

“We’re still going to get some perennials in there for evaluation, and they will always be there,” Ruter said. “We will always have a majority of summer blooming plants, but maybe we can have some other things that we can use for teaching purposes and that can help make (the garden) a little more showy other times of the year — rather than just during the summer.”

Planting for a more diverse blooming schedule will also bolster the garden’s reputation as a destination — both for visitors to the Classic City and for Athens’ residents. Support on-campus and from the general public will be integral to maintaining it as green space on campus for decades to come, Ruter said.

Like in every other part of the university, Ruter, Meg Green (Trial Garden supervisor), and her team of student workers and volunteers are operating within tighter budget constraints.

“We’re trying to make some renovations to the perennial gardens and work on efficiency,” he said. “How can we do things differently with the limited resources that we have?”

The garden will remain open to the public on a daily basis and continue its schedule of public and industry open houses throughout the year. Those seeking more information about the garden can visit ugatrial.hort.uga.edu.
