The Maryland Department of Agriculture urged residents to use caution when buying fresh holiday decorations and greens containing boxwood this past season, noting that using boxwood greens could potentially introduce a serious fungal disease called boxwood blight to surrounding boxwoods. Heading into the spring and summer months, the disease can easily move by attaching to gloves, clothes and tools so even though holiday decorations are down, it’s still something to watch out for. Boxwood blight is caused by a fungus called Cylindrocladium pseudonaviculatum. Symptoms begin as leaf spots followed by rapid browning and leaf drop starting on the lower branches and moving upward in the canopy. The key symptoms that make Boxwood Blight different from other boxwood diseases are numerous thin black streaks that develop on the green stems. Boxwood blight infects all above ground portions but does not appear to infect the roots. Fungus can remain alive in fallen leaves, which may serve as the source of infection for subsequent years as infected plants are exposed to moisture and temperature, severe blight and decline can occur. This fungus also produces sticky spores, which can be easily transported by human activities. The major means of transmission for boxwood blight is through moving plants and contact with contaminated clothing, tools or equipment according to the MDA. Sanitation is essential. Keep all tools clean and change clothing when working in the...

Considered to be the aristocrat of flowers, the orchid exemplifies the essence of sophistication and elegance. English merchant seamen brought the orchid home during the 19th century. The exotic colors and unique fragrances made them extremely popular among Britain’s wealthy, who were willing to pay extreme cost for these lovelies. Luckily, these flowers are now available to all at affordable costs. According to the U.S. Department of Agriculture more than $123 million worth of potted orchids are sold in the United States annually. The most popular season for these sales is between October and Mother’s Day. Orchid sales are second only to poinsettias. The Physics Factbook reports that there are approximately 20,000 species and 900 genera known making orchids the largest family of flowering plants in the world. All orchids are not created equal and therefore require slightly different care. Orchid classification is based on winter temperature needs for the plant. The orchid is usually classified as warm growing, cool growing and intermediate. • The warm-growing orchid needs 65 degrees at night and a range of 75 degrees to 85 degrees during the day; • The cool-growing orchid needs 50 degrees at night and daytime temperatures under 70 degrees; and • The intermediate growing orchid needs a night temperature of 60 degrees and daytime temps of 70 degrees F to 85 degrees. The intermediate-growing orchid is the most suited...
