The Amazing “Bat Flower”

January 30th, 2007

Tacca chantrieri

Now here’s an exotic flower from TPIE 2007.  As Barb Helfman and I toured the ever expanding show, we both agreed the purplish-black, whiskered "Bat Flower" was one of the more interesting that could be added to a BLOOMING PLANT program.  The Tacca leaves resemble a Spathiphyllum at first glance, but this plant is unrelated, first being given its own class botanically, the Taccaceae, and more recently being added to the yam family, Dioscoreaceae. 

Although the flowers must be staked, like orchids, to remain upright, they will last several months with adequate water and light.  I recommend trying them on Sippers subirrigation pegs to avoid premature wilting.  Currently they are available from sales@greendalenursery.com.  And please let me know what you think!

TPIE 2007 CELEBRATES A FRESH FOLIAGE ATTITUDE
More than 8000 industry professionals are starting off 2007 with a Fresh Foliage Attitude after attending TPIE in Ft. Lauderdale, FL. TPIE showed the foliage industry is back in full form despite visits by damaging hurricanes to some of Florida’s major foliage production areas in 2004 and 2005. Not only have plant supplies been restocked, but several companies were showing off entirely new varieties of plants, new packaging and merchandising ideas, as well as inventive foliage decorating concepts to catch the eye of consumers. Fresh ideas abounded at TPIE!

Hello From TPIE!

January 20th, 2007

Fresh attitudes, fresh ideas!  That’s truly the value of TPIE 2007.  Leslie and Stacey from The David J. Frank Company of Milwaukee, WI joined me for questions on the floor at TPIE. 

The topic?  Mealybug and its beneficial predator Cryptolaemus, complete from "Hot Times for Mealybug in the Night." on my web page.  Ah-h-h, the marvel of modern technology!

Drop me a comment and I’ll be happy to fill you in on all the good stuff I saw at the show.

Cheers!

See You at TPIE!

January 17th, 2007

The 2007 Tropical Plant Industry Exposition starts tomorrow at the Broward County Convention Center in Fort Lauderdale, Florida.  Not only is the timing a shot in the arm after the big, holiday push, but tropical plants and sunshine are a big boost to my creativity in the middle of winter.

Let’s see what new plants are available this year, and maybe a few new twists on old, familiar favorites.  New equipment?  Containers?  Everything a plantscaper needs to kick start the business into the new year.

I will be speaking on "The Fundamentals–what every technician should know" on Friday morning from 9:00-11:00 AM, and I hope to see many of my old friends there, as well as meeting many new ones.  Come up to me and tell me you saw my invitation on this web site, and collect a fantastic prize.  I hope to see you there!

Quarterly Scheduling of Special Services Work

January 16th, 2007

The memory of 2006’s holiday season is in ashes, holiday tear down is complete, and for those of us in the plantscaping business, that can only mean one thing: January pruning/cleaning time is here!

If we completed our quarterly pruning and cleaning of specimen plants in October, before the holiday decor was installed, it is now time to remove all the excess dust left behind from the holiday season.  If we didn’t get around to cleaning in the fall, the job will be twice as hard, but, clean we must. 

In a low light interior setting, dust limits the plant’s light level to a fraction of what’s avavilable, which for us is almost nothing.  Individual plants get cleaned on an onging basis while we are servicing them, but for specimen plants, the task is a little more complicated.

Since the extra time to prune and wash a tree and clean up afterwards does not normally fit into a technician’s workday, it generally requires the scheduling of some "Special Service" hours.  How much extra labor is needed depends on the job.

More (as in frequency), is better.  As far as scheduling goes, the more experience in cleaning and pruning someone has, the less time it takes to complete the tasks.  A proficient pruner and cleaner from way back, I know that if I do the pruning and cleaning on a quarterly basis, it will take me approximately an hour (each) to prune and wash a 95 gallon,15-20′ tall specimen tree, including preparation and clean up time. 

However, the same jobs on the same tree will take 15 minutes each if done on a monthly basis.  The choice is yours, and depends on manpower available as well as the travel time required–6 manhours a year for the monthly 15 minute job, or 2 people x 8 hours or 16 manhours/year for the quarterly job, which will need a much greater volume of water and clean-up time.  Travel time (times the # people) is then added to the labor total.  Obviously, with the proper training, 15 minutes of extra time per month would fit into the regular technician’s schedule, dramatically saving on extra labor and travel time.

Leaving the pruning or cleaning job on specimen plants go to six month intervals will not only more than double the labor time required, but also harm the health of plants that aren’t pruned and cleaned on a timely basis. 

Since we know Special Services work is needed at least quarterly to maintain the health and aesthetics of specimen plants, that means the next washing and pruning services will be scheduled in April, July, October, and then back to January, again.

The Value of GenX and GenY Employees

January 15th, 2007

The Bureau of Labor Statistics estimates that the lower birth rates during the 1960s-70s will create a 6 million person shortage in the American work force by 2008, and a 40 million person shortage by the year 2015.  Add to that the number of retiring baby boomers, and we are in the middle of a labor deficit, with every company vying for the same potential employees. 

The people available to fill the void are the GenX and GenY workers, who are as different from the baby boomer generation as we are from our parent’s generation.

13% Veteran Generation

48% Baby Boomers

23% Generation X

16% Generation Y

In the past seven years, the numbers in the first two categories have continued to decline due to death and retirement, while the last two categories have increased.  In order to grow successfully into the future, we must widen our managerial skills.

GenX and GenY are proficient computer users. Consequently, an organization’s web site is a particularly important recruitment tool for younger workers. Make sure the employment characteristics that matter most to them - such as mentoring and skill-building opportunities - are featured prominently.

As Generations X and Y move into the workforce, they’ll pose real challenges for plantscaping managers. Some of the current patterns will have to change, like scheduling, for example. "Cutting-edge organizations build flexibility into schedules in incredibly creative ways," says Sharon Jordan-Evans, a retention expert and executive coach in Woodland Hills, CA.. "It’s hard work but this is the only way you’ll hang onto GenXers and manage them effectively."

In the past, the plantscaping organization has run on the backs of dedicated people willing to work extra hours, and put clients’ needs above their own. "We don’t really know what level of resources it takes to run a plant maintenance service," Jordan-Evans says. "In the past, technicians worked extra hours and managers worked 60-hour weeks. They enabled a dysfunctional system to limp along. We cannot expect this to continue."

She adds, "The key to managing GenX and GenY is to ask them what matters to them, and really listen to their responses. Even more, it’s time to engage them in helping to figure out solutions. Before long, it is going to be their organization."

Hot Times for “Mealybug in the Night”

January 13th, 2007

In the specific case in question of my December post regarding innumerable mealybug in the atrium of an Embassy Suites, the solution that makes the most sense both economically and environmentally is beautifully described in the Cornell University publication that follows.  No infestation of citrus mealybug is too hot for the Cryptolaemus montrouzieri ("Mealybug Destroyer") to handle! 

Read below to learn about this very useful citrus mealybug control, and let me know if you need more specifics about releasing them in the most effective and time efficient manner.

Cryptolaemus montrouzieri
(Coleoptera: Coccinellidae)

Mealybug Destroyer

This beetle was imported into the United States in 1891 from Australia by one of the early biological control pioneers, Albert Koebele, to control citrus mealybug in California. Although C. montrouzieri initially devastated the citrus mealybug populations in citrus groves, it was unable to survive the winter except in coastal areas.

Appearance

    Cryptolaemus montrouzieri is a small (about 3-4 mm long), dark brown lady beetle with a tan to orange head and posterior. The larvae grow up to 1.3 cm in length and have woolly appendages of wax (their true legs are barely visible underneath) which makes them resemble mealybugs, although they are about twice as large as the adult female citrus mealybug. C. montrouzieri eggs are yellow.

Habitat

    Citrus groves in the coastal areas of California, interiorscapes, and greenhouses. In addition, C. montrouzieri is released seasonally into inland citrus orchards.

Pests Attacked (Host Range)

    C. montrouzieri attacks citrus and closely related mealybugs and some soft scales, including hemispherical scale and its relatives. It is considered an important predator of citrus and long-tailed mealybug in greenhouses and interior plantscapes and is being introduced in a biocontrol program in the West Indies to control pink hibiscus mealybug.

Life Cycle

    Adult females lay eggs among the cottony egg sack of adult female mealybugs. Eggs hatch into larvae in about 5 days at 27°C (80°F). The three larval stages last from 12-17 days during which the larvae feed on mealybug eggs, young crawlers, and the honeydew produced by mealybugs.

    C. montrouzieri pupates in sheltered places on stems or on greenhouse structures. Adults emerge after 7-10 days and live four months. Four days after emerging, adult females begin to lay eggs, and the lifetime total may be as many as 400. Adults may live up to 2 months.

Relative Effectiveness

    C. montrouzieri is a voracious feeder of mealybug in both the larval and adult stages - a single larva may consume up to 250 small mealybugs. They are most effective when mealybug populations are high, and repeated releases may be necessary if mealybug populations are low. They require cottony egg masses for egg-laying (long-tailed mealybugs do not have cottony egg masses). Although adults and young larvae prefer to feed on mealybug eggs, older larvae will attack any mealybug stage. Adults can fly and cover large areas to search for food. If mealybugs are scarce, they will fly off in search of other related insects, e.g. aphids and soft scales, although reproduction is substantially greater on mealybugs.

    Because C. montrouzieri cannot survive cold winters, they must be reintroduced into orchards where mealybugs were a problem the previous year in the early spring . The exception is moderate coastal regions.

    Like other ladybeetles, C. montrouzieri tends to disperse when released. In indoor sites, keep windows and vents closed the day of release. Recent studies have shown that adults and larvae will spend more time searching a leaf for mealybugs if it has honeydew than if honeydew is absent.

    Although mealybug destroyers will not persist after the mealybug population has been controlled in small greenhouse areas, in more complex interior areas where there are multiple infestation sites and alternate prey, they do perist. In Indianapolis, a single release of 100 beetles has persisted for over 5 years. If birds exist in interiorscapes, however, they will feed on adult beetles.

Conservation

    It is important to remember that C. montrouzieri superficially resembles its prey, the mealybug. This can cause problems if large numbers of larvae are present on crops that are ready to be shipped or in indoor situations (such as malls) where the public may be unaware of the benefits of natural enemies.

    For general information about conservation of natural enemies, see Conservation in the Tutorial section on this site, or the Volume II, No. 1 Feature Article on conservation in the Midwest Biological Control News Online.

Pesticide Susceptibility

    Little is known.
