New Apple Variety Bred Specifically For Local Pick-Your-Own Orchards

We are in luck, a fresh apple experience is coming our way. University of Maryland has released the first apple variety developed for the mid-Atlantic region called Antietam Blush. Six more varieties will follow, all adapted to the area’s summer heat and humidity, with increased drought and disease resistance. Antietam Blush is the first apple variety bred specifically for this area.  The trees are shorter, thus eliminating the need for ladders, and designed to be picked in October (good for pick your own orchards). The stronger tree architecture makes it easier and less labor intensive to maintain plus this variety is bred to be resistant to the fire blight bacterial disease.  Because the trees are smaller, they can be planted closer together without support, which means more apples can be produced. The apple is blush red, sweet and slightly tart, with a high sugar/high acid fruit content that stores well. Dr. Christopher Walsh, Professor in the Department of Plant Science and Landscape Architecture, College of Agriculture and Natural Resources, University of Maryland, says that Antietam Blush combines the tartness of its parent, Cripps Pink, with the champagne fizz of its grandparent, Gala.

Dr. Walsh and then-graduate assistant Julia Harshman worked on this new kind of apple tree for nearly 30 years. When they started the main university apple breeding programs were at Cornell University, Washington State University, and the University of Minnesota. No one had bred an apple specifically for the mid-Atlantic region.  They recognized the need for an apple tree that would tolerate the hot, humid summer climate. Over time they bred trees to combine a heat tolerant fruit with a tree architecture that reduced the need for hand pruning and ladders. Dr. Walsh received the University’s first ever apple patent for Antietam Blush. Currently, several Maryland growers are growing Antietam Blush, which will be available to the local markets very soon. Check out the University of Maryland’s short video about Antietam Blush.

Master Gardener Program: Learn to Garden While Getting Involved with Local Community

The Master Gardener program is a great way to learn more about gardening, meet new friends, and get involved in civic projects.  Conducted throughout the United States, the program usually is managed on a county level through state/county extension agents. Interested gardeners receive a manual and horticultural training from horticulturists and experts in the field. In return, they volunteer to assist the community with a variety of activities such as staffing plant clinic booths, answering phones, teaching, gardening in community areas, helping youth or elderly with gardening, etc. The program was initiated as a means of extending horticultural and pest management expertise of the state extension office to the general public. Usually the fee is the cost of the manual and a promise to volunteer and continue with education for a fixed number of hours annually. Becoming a Master Gardener is like joining a gardening club with many extended learning opportunities. Below is information for the Washington DC metropolitan area. More detail is given for Virginia to illustrate the difference in commitment and schedules across counties. Maryland and Washington DC are similar. All have fees and a registration process.


The Virginia Tech University manages the Virginia Cooperative Extension (VCE) program which has extension agents at every county. The extension agent manages the county Master Gardener program. The following is a snapshot of five Master Gardener programs in Northern Virginia to give an idea of the application deadlines, times/days programs are offered, cost, and the commitment in terms of hours. For example, if one works full time in an office and can only attend evening classes one may find a program that offers evening classes and does not limit registration to county residents. Or some programs have one class a week instead of two thus extending the education over a longer time but making it more manageable.

In Fairfax county, there are two Master Gardener programs due to the high level of interest. Green Spring, part of the Fairfax county park system, manages a 13-week Master Gardener program that starts in September and ends in November. The classroom training is held at Green Spring on Tuesdays and Thursdays, 1:00 to 4:00 pm and labs on Saturdays. When the trainees complete the classroom part, they graduate to become Master Gardener interns. They have to complete 50 volunteer hours within one year including 15 hours working at the Master Gardener Help Desk.  They retain their certification by completing 20 hours of volunteer service hours and 8 hours of continuing education in horticulture per year. http://www.fairfaxcounty.gov/parks/greenspring/gsg-mastergardeners.htm

The other Fairfax county Master Gardener program has classes at Merrifield Nursery at Fair Oaks. The classes are January through March, one day a week for 3 hours, during the day or evening. To become a certified Master Gardener, one has to complete 30 hours of classroom education per year for 3 years, and 24 hours of community service per year for 3 years. Once a person becomes a certified Master Gardener, one has to complete 8 hours of continuing education and 24 hours of volunteer work per year. http://www.fairfaxgardening.org/join-us/

In Arlington county, classes start in the beginning of September, Tuesdays, from 9:00 am to 3:30 pm, and last 12 weeks. Classes are held at the Fairlington Community Center in Arlington and other local garden venues. There is no application deadline and acceptances into the program are determined by mid-August. Residents of Alexandria City and Arlington receive preference and all training and internship hours must be completed in the Arlington/Alexandria. After 66 hours of classroom training, the trainees must complete a 60-hour internship to hone their skills in core Master Gardener educational projects within one year of training. Once the classroom program, internship, and student project are completed participants become certified Master Gardeners. To maintain certification, they must volunteer a minimum of 20 hours and attend 8 hours of continuing education programs per year. http://mgnv.org/about/become-a-master-gardener/

In Loudoun county, classes are twice a week for 10 weeks, from January through March, at 750 Miller Drive, Leesburg. The Master Gardener program requires 60 hours of classroom education and 75 hours of the internship. Certified Master Gardeners must complete 25 volunteer hours and 8 hours of continuing education per year. http://loudouncountymastergardeners.org/become-a-master-gardener/training-requirements

In Prince William county, the program runs from September through December and requires 75 hours of classroom education and 50 hours of internship. To maintain certification, Master Gardeners must volunteer 20 hours and complete 8 hours of continuing education per year. http://www.mgpw.org


The Maryland Master Gardener Program is administered by the University of Maryland Extension and each county has a coordinator and its own schedule of classes. For a table of county coordinators’ contact information, see http://www.extension.umd.edu/mg/find-local-mg-program.

Washington, DC
