Department of Entomology, University of Maryland Abstract The occurrence of the azalea lacebug, Stephanitis pyrioides (Scott), was monitored on azaleas, Rhododendron spp., in 4 suburban Maryland communities. Azaleas planted in full sun for all or part of the day were significantly more likely to be infested with lacebugs compared to those planted in shade. Furthermore, on a communitywide basis, the proportion of azaleas infested with lacebugs was directly related to the proportion of azaleas planted in full sun. Azalea growers can reduce the lacebug occurrence and associated pesticide applications by planting azaleas in the proper site. Several recent studies indicate that azaleas (Rhododendron spp.) are the most widely used woody ornamental plant in suburban Maryland home sites where they comprise 10-20% of the total woody ornamentals encountered (2, 3, 6). The azalea lacebug, Stephanitis pyrioides (Scott) is a major pest of azaleas throughout the eastern United States. (4). Due to the ...

Rhododendron is large genus in the heath (Ericaceae) family includes some 800 species, which are widely distributed across the Northern Hemisphere, with the majority growing in temperate to cool regions. Gardeners can choose from many different types of rhododendrons: Alpine rhododendrons, with small leaves, wiry stems, and clusters of tiny flowers; shrub rhododendrons, including those up to 15 ft (4.5 m) tall; tree rhododendrons, with a single trunk and a large head of foliage; evergreen azaleas, which are low to tall bushes with semi-persistent foliage and large light-textured flowers; deciduous azaleas, which are large twiggy bushes with flowers usually in shades of yellow, red, or orange; and vireya rhododendrons, which are tender tropical species with funnel-shaped blooms and no fixed flowering season. ...
Rhododendron calendulaceum, also known as the Flame Azalea, is surely one of the most spectacular native shrubs of the Appalachian Mountains. The flowers are larger than most of the natives, measuring from 1.5 to 2.5 inches across, and come in a wide range of colors from clear yellow, through shades of orange, to brilliant red. First collected by A. Michaux in 1795 from the Blue Ridge Mountains of North Carolina, this species has a wide range of distribution from southern New York, Pennsylvania and Ohio as a northern limit, southward through the Appalacian mountains to northern Georgia. In late May and June, entire hillsides can be washed with brilliant color as these magnificent azaleas come into bloom. R. calendulaceum is difficult to propagate by cuttings, but is easily raised from seed. Please leave the plants in the wild for others to enjoy, and purchase blooming-sized seedlings from specialty nurseries for garden use since young plants establish easlily in the garden. R. calendulaceum is a ...
AURORA - Rhododendrons and azaleas herald spring in Oregon. And spring is a good time to give these beautiful shrubs the care they deserve.. There are a number of things home gardeners can do to keep rhodies and azaleas long-lived and healthy, according to Jan McNeilan, retired horticulturist with Oregon State University Extension Service.. As with all health check-ups, start with a physical examination. Look for symptoms of nutrient deficiency, such as pale green or dwarfed leaves, which may indicate a lack of nitrogen. Yellow mottling along the leaf margins may indicate an excess of potassium. If the leaves are smaller and darker green than normal and the tips are dead, your shrub may need phosphorus. Yellow or yellow-white (chlorotic) leaves may mean there is too much calcium, which can be leached from sidewalks and foundations. When the soil pH is too high for acid loving rhodies, some nutrients are tied up in the soil and unavailable to the plant.. Be mindful of past weather conditions when ...
Information concerning the area of origin, genetic diversity and possible acquisition of germplasm through hybridization is fundamental to understanding the evolution, ecology and possible control measures for an introduced invasive plant species. Rhododendron ponticum is extensively naturalized in the British Isles, but it is not known whether native material in Turkey, Spain or Portugal gave rise to the naturalized material, or to what extent introgression has affected this material. Chloroplast (cp) and nuclear ribosomal DNA (rDNA) restriction fragment length polymorphisms (RFLPs) were sought which could distinguish between native material of R. ponticum, and between 15 other Rhododendron species including R. ponticums closest relatives. Thereafter, a total of 260 naturalized accessions of R. ponticum from throughout the British Isles was examined with respect to informative polymorphisms. It was found that 89% of these accessions possessed a cpDNA haplotype that occurred in native material ...

Azalea bushes thrive under the partial, filtered shade of pine, hickory and Oak, along with companion dogwood trees and camellia shrubs. Azalea plants prefer grown in partial shade ( 4 to 6 hours of sun but not during mid day ), and when planted next to buildings, the north side offers protection from cold damage. The flowers of the azalea plant last longer in filtered pine tree shade because of the cooling effect. Pine tree straw, pine cones, and pine tree bark make excellent mulch under azaleas because it both cools and acidifies the soil. When planting azalea bushes, the shrub should be put into a landscaped hole containing 1/2 soil & 1/2 organic matter, such as peat moss, leaf gro or pine bark. Azalea plants are very shallow rooted and do not do well in compacted or heavy clay soils ...
Rosebay rhododendron (Rhododendron maximum L.) is an evergreen ericaceous shrub that plays a dynamic role in the southern Appalachian forests. Commonly located on mesic sites, this understory shrub forms dense thickets that greatly reduce the amount of light available to herbaceous and woody plants found on the forest floor. Past research has shown that silvicultural methods can be used to eradicate R. maximum, however it is unclear which of these methods is most efficient and what effects other than stem mortality may occur. In this study, treatments involving prescribed fire, mechanical cutting, and herbicide applications were applied to R. maximum dominated forests in southwestern Virginia to determine what effect seven different silvicultural treatments had on 1) controlling of R. maximum as a forest weed 2) fuel loading inside of a R. maximum thicket, and 3) canopy tree seedling regeneration. Mechanical cutting treatments were successful in reducing R. maximum basal area per acre; however ...

There are seasons for all types of plants. For example, you might think of hibiscus during the spring and summer seasons, and pansies and snapdragons during the fall and winter seasons. Many southerners think of colorful blooming azaleas during the spring season. But spring isnt the only time these beauties should be thought of. If you grow azaleas, or would like to grow them, heres a few tips to help with their care. For beautiful, blooming azaleas, you need to provide some additional care during the summer and fall. Keeping them well watered during our hot, dry summer months, well fed and controlling any pests that may show up will help to create the beautiful bloomers you want next season. Azaleas shrubs have lots of shallow feeder roots, which means they can dry out quickly. When you water, be sure to apply enough to thoroughly soak the planting area. This should be accomplished by a long, slow watering routine, maybe once or twice a week, depending on your soil and planting location. Do ...
Rhododendron ungernii This lovely species is in Subsection Pontica, along with many of our most familiar species (R. maximum, ponticum, catawbiense, brachycarpum, smirnowii, and yakushimanum). It seems most closely related to R. smirnowii. It was named after Baron F. von Ungern-Sternberg, 1800-1868, a professor at Dorpat University. R. ungernii is found in Northeast Turkey in the Caucasus Mountains at 2500-7000 feet. It generally grows on the north side of steep, moist, shady slopes along with beech, spruce, and fir. R. ungernii is often found with R. ponticum and R. smirnowii though the range of ungernii is broader than that of R. smirnowii and extends into Russia. Natural hybrids of ungernii and R. smirnowii are often found.. R. ungernii was first found by G. N. Kazbek in 1874 near Artvina, a city near the Black Sea in Turkey. Twelve years later it was described by E. R. Trautvetter. In 1886 it was brought to the St. Petersburg Botanical Garden and from there both R. ungernii and R. smirnowii ...
Rhododendron macrophyllum - This evergreen shrub has leaves with a distinctive metallic sheen. The compact flower trusses, produced in spring, are composed of tubular flowers with spreading lobes to 3.5cm (2 inches) wide and as long. Flower color varies from plant to plant, from rose-purple to pink or white, with some bicolour forms. Height and spread to 15 feet.
Rhododendron delavayi Franch is an evergreen shrub or small tree with large scarlet flowers that makes it highly attractive as an ornamental species. The species is native to southwest China and southeast Asia, especially the Himalayan region, showing good adaptability and tolerance to drought. To understand the water stress coping mechanisms of R. delavayi, we analysed the plants photosynthetic performance during water stress and recovery. In particular, we looked at the regulation of stomatal (gs) and mesophyll conductance (gm), and maximum rate of carboxylation (Vcmax). After four days of water stress treatment, the net CO2 assimilation rate (AN) declined slightly while gs and gm were not affected and stomatal limitation (SL) was therefore negligible. At this stage mesophyll conductance limitation (MCL) and biochemical limitation (BL) constituted the main limitation factors. After eight days of water stress treatment, AN, gs and gm had decreased notably. At this stage SL increased markedly and MCL

Azaleas have shallow roots, and prefer moist, well-drained soil with a pH between 4.5 and 6.0. If in doubt, you can submit soil samples through your County Extension Service to have the pH and nutrient levels tested, usually for little or no cost. The test results will also have information about changing the pH if needed, which will be appropriate for your soil type and climate.. Check how well your soil drains by filling a hole with water. If it is empty in a few hours, it drains well. If not, you have so-called "heavy" soil. In heavy soil, dont plant azaleas into small holes filled with amended soil, since the holes will hold water and be death traps for the plants. Instead, you can build raised beds, or amend a large area, or "plant high", ranging from an inch or so above ground level to planting on top of the ground, and mounding amended soil around the root balls.. Azalea roots need access to both moisture and oxygen. In wet soil, the roots will grow closer to the surface to get oxygen. ...
Based on your zip code, you are gardening in zone 5A or the coldest part of zone 5. Depending on your gardens microclimate it might actually be as cold as zone 4. I would suggest you work with your local professional nursery staff to identify azaleas that might do well for you. They will have localized experience which is much more accurate than going by a reference book. The University of Illinois does indicate that this one is hardy to zone 5A, which is encouraging. It also notes it is semi-evergreen there so I would expect it to lose foliage where you are no matter which zone specifically you come under, this is not so unusual for azaleas at the colder end of their range. I did find several commercial nursery sites also listing this variety as hardy to zone 4. (Note that there are several azaleas named Karen, one from Girard which is typically listed as zone 5, and another Kurume which is even less winter hardy.)

Dowco 269 [2-chloro-6-methoxy-4-(trichloromethyl) pyridine] effectively controlled Phytophthora cinnamomi on rhododendron. Soil drenches (300 µg/ml) before inoculation prevented root rot, whereas drenches applied after inoculation did not. Dexon drenches were ineffective. Ethazole was less effective than Dowco 269, but a 375-µg/ml drench prevented root rot. In greenhouse tests, a 100-µg/ml drench or 1.12 kg/hectare(ha) furrow treatment of Dowco 269 effectively controlled soybean root rot caused by Phytophthora megasperma var. sojae. Furrow treatment with ethazole (1.12 kg/ha) was equally effective, but phytotoxic. Slight stunting was caused by 2.24 kg/ha Dowco 269. Foliar sprays with Dowco 269 delayed appearance of rhododendron and soybean root rot symptoms, indicating that systemic uptake of Dowco 269 by leaves and stems, and movement into roots may occur. Dowco 269 does not eradicate P. cinnamomi or P. megasperma var. sojae, race 1, from infected rhododendron or soybean plants.. Additional ...
Dulce Et Decorum was a poem written by Wilfred Owen when he was in hospital. It is a poem that is most commonly known because of the bitter truth that Owen writes with. Owen writes "Dulce Et Decorum Est" with many poetic techniques such as similes, metaphors, personification, rhyming, alliteration, hyperbole, onomatopoeia, direct speech and irony. Irony is a key factor that shapes Owens poem Dulce Et Decorum. Dulce Et Decorum Est is Latin for "It is Sweet and" which is then completed in the last lines of the poem to be "dulce et decorum est pro patria mori" which translates to "it is sweet and glorious to die for ones country". The irony shines through this because throughout the whole poem Owen is talking about how men are "like old beggars" and "In all my dreams, before my helpless sight, he plunges at me, guttering, choking, drowning." Owen then further portray the irony in war by stating "the old lie:" just before he writes "dulce et decorum est pro patria mori" The whole irony that is ...
ANSWER: Many azaleas did not survive the droughts over the last 3 out of 4 years, especially those in full sun. Azaleas prefer moist acidic woodland soil and filtered shade. They have shallow root systems. Your white oaks also compete with the azaleas for water. If your mulch is over 2 or 3 inches it may have been a barrier to the little rain we did receive. Drought and drying winter winds both weaken plants and make them more susceptible to problems. If your azaleas winter injury is sunscald, they may recover. If the branches have blackened spots on the bark, also known as cankers, or are dropping dead branches, they may have a fungal disease. In any case, it is crucial to find the exact problem before using pesticides or fertilizers, as these can aggravate plant injury. To further pinpoint the symptoms, use the diagnostic chart on our publication, IPM: Azaleas and Rhododendrons. Read it online or call us and order.

Atmospheric nitrogen dioxide (NO2) is an environmental oxidant that is removed through direct uptake by foliage, but plant responses to this highly reactive gas are not well understood at the molecular level. From NO2-exposed leaves of a woody azalea (Rhododendron mucronatum), we cloned two cDNAs (RmGLP1 and RmGLP2) for germin-like proteins (GLPs), a group of ubiquitous plant proteins that have been implicated in various plant physiological and developmental processes. Quantitative analysis of mRNA expression, together with immunoblotting data, showed that foliar exposure to NO2 caused a robust induction of these GLP-encoding genes. When produced in tobacco cell culture, recombinant RmGLP2 was secreted into the apoplast, where it exhibited superoxide dismutase activity. RmGLP1 and RmGLP2 represent the first examples of plant genes that are responsive to airborne NO2. These enzymes might have a potential role in extracellular defense mechanisms through attenuation of interactions between reactive ...
