Hello and welcome to June!

Hydrangea Lovers Time to Shine

We missed last month due to a cantankerous computer. I will not go into details because anyone who has had a computer has seen the dreaded blue screen. It probably results from a Microsoft computer nerd who embedded a secret string of programming code in every operating system that locks up your computer to frustrate you enough to buy the next upgrade of their software that promises no more crashes. Did anyone see “A Beautiful Mind”? As Dr. Pat Cobb, our great AU young retired entomologist once philosophized to me after one of my many other major blunders, “Did anyone die, Ken”? That puts things in perspective. Nuff said.

I will start where my memory is freshest. I just returned from the Hydrangea Meeting (maybe I should say THE Hydrangea Meeting) sponsored by the Center for Applied Research at McCorkle Nurseries in Dearing, Georgia. Between 100 and 200 back yard plant nuts and assorted nursery growers along with us government employees gathered to hear the A to Z of hydrangeas. It was a great meeting and I quickly ascended to a higher level on the learning curve. Of course, as you know, the higher you get on that curve, the steeper the curve gets or as is often said, “the more you know, the more you see that you do not know……" or something like that.

Some of the heart stopping macrophylla cultivars that I saw included: ‘Ayesha’, ‘Lemon Zest’, ‘Goliath’, ‘Penny Mac’, ‘Dooley’, ‘Pretty Maiden’, ‘Sister Therese’, ‘Preziosa’ plus a host of others. I am sure I have left out 5 or 10 “gotta-haves”. Look out for the “remontant” (I learned that meant come-backers or repeaters or recurrent) bloomers. ‘Endless Summer', which is pink in our

Hydrangea mycrophylla 'Endless Summer'

which is pink in our pictures, will be blue in acid soil but will set bud, bloom and repeat after 10 to 12 weeks. Breeding is underway to bring many more along.

There are a host of lacecap cultivars that are enough to make you send in your dues to be a member of the National Society of Hydrangeas ($15). Some cultivars that caught my eye were ‘Veithcii’ (breeding work with this cultivar has great promise for new things in the near future), ‘Kardinal’, ‘Blue Billow’, ‘Blue Wave’, and ‘Grayswood’.

Hydrangea paniculata cultivars that require your attention include ‘White Moth’ (a possible tree form), ‘Pink Diamond’, ‘Chantilly Lace’ introduced by Kay Bowman at the Center for Applied Nursery Research (this name should be irresistible to the baby boomer group), ‘Unique’, ‘True Unique’, and ‘Floribunda’.

Everyone needs a collection of our Alabama State flower, Hydrangea quercifolia. Most of the

Oak leaf hydrangea

cultivars come from northern Alabama. ‘Snowflake’, ‘Snow Queen’, ‘Harmony’, ‘Peewee’, and ‘Alice’ are all great and worthy of being in every landscape in Alabama. I just left mine in bloom at home and they represent Alabama well. We need to make sure every Alabama citizen has at least 2 or 3 and that they are prominently displayed at the State Capitol.

‘Annabelle’ is a cultivar of Hydrangea arborescens and has won every award possible as a plant

Hydrangea arborescens 'Annabelle'

introduction. It still has not made the impact that it should in the gardening world. No one sees these plants without pulling out the checkbook. ‘Hayes Starburst’ is a new introduction and has all florets as double with a cascading, waterfall effect. It was found as a chance seedling in the garden of Hayes Jackson, a county agent in Anniston and a certified plant eccentric. I talked with Hayes and he said he lost his original plant to voles and will have to go to Nurseries Caroliniana in North Augusta, SC to get a replacement plant. This shows the value of getting your treasures out as quickly as possible in case a tragedy of this kind occurs.

A plant that we brought back from China that we were very excited about having as a new and exciting introduction was Dichroa febrifuga. However, as I attend many meetings I have found that collectors and now landscapers are using this plant in designs already. Our selection may offer some advantages but these plants are available on a limited basis. It is an evergreen hydrangea relative with a lacecap flower. It is hardy in Zones 8 – 10 but needs shade and protection from the wind to offer its best side. I look forward to watching this plant over the years and getting it out to the trade.

Decumaria barbara, woodvamp or native climbing hydrangea, is one of the lesser known plants that was offered as one of those plants that you can not understand why gardeners are not lining up at the nursery gates to have. It is a beautiful deciduous clinging, climbing vine that has glossy leaves and is great for a shady arbor. You can find a picture of this vine on our Plant ID Resource option on our web page at www.ag.auburn.edu/landscape. Click on the Plant ID button and type in Decumaria.

The United States Department of Agriculture has found vinegar to be a potent herbicide and an inexpensive and organic alternative. Researchers tested vinegar made from fruits or grains to conform to organic farming standards on common lamb's-quarters, giant foxtail, velvetleaf, smooth pigweed and Canada thistle. Concentrations of 5% and 10% killed weeds less than 2 weeks old. Older weeds required higher vinegar concentrations such as 20%. At higher concentrations, vinegar had an 85%-100% kill rate at all growth stages. For more information contact: teasdale@ba.ars.usda.gov

Final results of an economic impact study of Florida horticulture are in. In 2000, the state's green industry had sales of $9.9 billion, an increase of 33% from 1997. Grower sales nurseries, sod farms and florist products rose to $2.25 billion. Landscape sales totaled $3.11 billion. Horticulture provided 188,000 jobs in Florida in 2000, an increase of 13% from 1997.

Those who grow ornamental crops are familiar with fungal leaf spot diseases. It is almost impossible to accurately identify these diseases unless you send a sample to a laboratory. If you know which disease you are dealing with you will be more able to choose the correct product. Fungal leaf diseases rarely kill plants but they disfigure them, resulting in financial losses.

Plant pathologists stress the importance of using cultural control strategies to control these problems. Their suggestions include: minimizing exposure to overhead irrigation and rainfall; employing pathogen-free seeds, cuttings and plugs; using resistant cultivars. Obviously, if your crops are outside some of these suggestions are unworkable.

Currently, fungicides are the most common and often only line of defense a grower has against the fungal leaf spot diseases. Growers often select very wide spectrum fungicides to cover a variety of problems. There are a number of products that have been on the market for many years as well as newly developed formulas. The responsible grower needs to rotate between products so that he/she is using more than a single active ingredient.

There are many things to consider when deciding how best to deal with leaf spot diseases: disease pressure, ease of application and direct fungicide costs. The most cost-effective approach is prevention in combination with cultural disease controls such as pathogen-free plugs or cuttings and the minimization of overhead irrigation. Also, be very careful to follow product labeling.

Consumer surveys were conducted at Purdue University and the University of Florida. Results were interesting in that consumers appear to appreciate new varieties.

Ten red, 10 novelty and 125 different poinsettia cultivars were placed on display in the conservatory greenhouse at White River Gardens, Indianapolis, Indiana from late November until late December 2001. 861 survey forms were completed for the 125 cultivars, 1,073 for the red and 1,239 for the novelty groups. There didn't seem to be any significant difference between age, gender and purchase characteristics of the consumers in the survey.

Orange-colored bracts did not attract consumer attention in the survey. Also, Freedom Red, which has been extremely popular in the past, was not very highly rated in either survey, red or overall.

The Florida study did comparisons between groups of plants. Respondents were asked their preference between two dark red poinsettias. Sixty-six percent chose Chianti and 34% chose Freedom Red. Respondents were asked their preference for red bract color: 45% chose Christmas Cookie, 40% chose Orion and 15% chose Cortez Dark Red. When asked to choose between Cortez Burgundy and Plum Pudding, 67% chose the former and 33% chose the latter.

From the University of Florida surveys it appears that novelty cultivars are more appealing than the traditional favorites. Growers must be careful in their selections, though, as many of the new cultivars are challenging to grow.

April was a busy month for plant samples with the 136 plant samples submitted. Many of these samples were ornamentals, and turf samples were numerous during the last week of April. Anthracnose diseases and Phytophthora root/crown rots were seen on several samples.

Anthracnose diseases are leaf spot/blight diseases caused by a group of fungi that produce a particular type of fruiting structure. Last month we saw anthracnose leaf spot/blight diseases on Hosta, Hydrangea, Jade, Asiatic lily, Mexican heather, and strawberry. The Hydrangea, Jade, Asiatic lily, and Mexican heather samples showed the usual leaf spot and blight symptoms characteristic of anthracnose. The specific leaf spot characteristic vary with the particular fungus and plant. Many anthracnose diseases are caused by the fungus Colletotrichum. Generally, leaf spots tend to be round or oval and pale in the centers. Fruiting bodies often develop and appear as scattered black, cream, or orange specks on the surface of the leaf spots. Sometimes, these bodies are arranged in ring-like patterns.

Anthracnose leaf spots sometimes are described as zonate spots and the zonation often relates to the fruiting body arrangement. Disease control involves sanitation, reducing humidity levels, and sometimes the application of protective fungicide sprays.

Phytophthora crown rot or root rot was diagnosed on aucuba, boxwood, Yoshino cherry, and desert rose. Also, late blight was identified on Irish potato in Baldwin County. The crown and root rot diseases were typical of Phytophthora. Tissues developed a wet, watersoaked, dark brown, rotted characteristic. Outer cortex layers easily pulled away from the inner central cylinder. These diagnoses were made by ELISA and culture work. Phytophthora, like Pythium, requires wet conditions in order to be active. The late blight on the Irish potato showed the usual black, wet, spreading foliage blight typical of late blight. With Phytophthora root and crown rots, damaged plants should be removed and destroyed. Water levels in the area should be closely monitored. Soil or media drainage should be good. Protective fungicide drenches are usually recommended only in nursery or greenhouse situations. For late blight of field Irish potato, protective fungicide sprays are usually necessary.

Fireblight on ornamental pear has been noted. Usually the bacteria enter through the blossoms and then blight spreads downward from that point. Pruning severely, 9-12 inches from the damage, is usually recommended as the bacteria may spread to a considerable distance from the noticeable blight symptoms.

We received 120 samples for the month of April. Brown patch was the most common disease on turfgrass, with several samples on zoysiagrass and two samples from centipedegrass. Spider mites (southern red mite, spruce spider mite) were observed causing problems on several ornamental samples. A cabbage sample was brought in with a severe case of downy mildew. Downy mildew symptoms first appear as small spots on the leaves, which are first yellow but later turn brown with bluish-black irregular spots. In moist weather a downy white mold develops on the underside of the leaf spots. Downy mildew is promoted in cool, wet weather. The disease is most serious in seedbeds and young plants may be killed in only a few days. Bravo or Daconil (Homeowners), Aliette, and Kocide are labeled for downy mildew control in cabbage.

We also received samples and calls concerning Asian ambrosia beetles. These small beetles (c inch long) attack a wide range hosts in nursery and landscape settings. This spring we have received reports of damage to fig, crape myrtle, cherry, peach, oak, and Japanese maple. Plants recently installed in the landscape are particularly susceptible to Asian ambrosia beetles. Infestations can be identified by tooth pick-like strands of boring dust protruding up to a few inches from stems and branches of damaged plants. Heavily infested plants should be removed and destroyed. Insecticide applications to surrounding plants may help protect against infestation. The insecticide permethrin. (Astro and other formulations) has shown good efficacy against this pest. Follow label instruction carefully. More information on the identification and control of this pest can be found at the following web sites: www.ces.ncsu.edu/depts/ent/notes/&T/trees/note111/note111.html and www.bugwood.org/factsheets/99-010.html

Disease Possibilities for May

As is usual in May, we are seeing an abundance of turf grass samples. Thus far, many of our turf samples have involved non-infectious situations as is typically the case for turf problems sent to us in April and early May. We have, however, seen a few cases of brown patch and take-all patch disease thus far this spring. Also seen recently are tan spot (Drechslera tritici-repentis) on wheat and a mosaic virus-like problem on wheat in some areas in North Alabama.

Go to: Disease Reports see a list of some common disease problems received in the lab during April of the past few years. Comments on control practices are brief. Refer to the fact sheets, timely informations, 2000 or 2001 spray guides, and the Alabama Pest Management Handbook for details.
