Ask A Master Gardener

TARBORO — “Ask A Master Gardener,” published weekly, helps our readers to solve common problems concerning horticulture, gardening, and pest management through a trained and supervised staff of Extension Master Gardener volunteers.  The Extension Master Gardener program is an educational program designed to enhance public education in consumer horticulture.

Submit your questions by email to askemgv@gmail.com.  Or, you can call the local Extension Center at 252-641-7815 and tell them you have a question for a master gardener. You ask the questions and a local Master Gardener will return your call with a solution to your problem and share it with our readers.

Answers reflect research collected from land grant universities (NCSU or NCA&T) and through a national extension website, www.extension.org.  

Q. Noel C. (Tarboro) asks – I think my roses have some kind of blight.  Blooms are smaller and the leaves have brown/black spots and turn brown and fall off. Stems seem to be drying up.

A. These symptoms could be the result of an infection by a virus. A virus is a submicroscopic disease-causing entity that can only be viewed with an electron microscope. Some symptoms typically associated with viral infections include: distorted and malformed leaves or growing points; stunted growth; a mosaic pattern of light and dark green or yellow on leaves; yellow spotting on leaves; other spots or line patterns on leaves; and cup-shaped leaves. However, virus diseases cannot be diagnosed on the basis of symptoms alone. Some of these symptoms can also be caused by high temperatures, insect-feeding, growth regulators, herbicides, and nutrient deficiencies and excesses. The best way to tell if a virus is infecting a rose is if the same symptoms occur year after year. If the deformed or abnormal growth never disappears, dig out the entire infected plant and replace it. The reason it is necessary to remove the plant is that a virus is systemic - found in all parts of the plant. So, pruning away the afflicted parts will not remove the virus from your rose. There are no chemicals that cure a virus-infected plant or any that protect plants from becoming infected. Your only course of action is to rogue-out the infected plant and discard it.

To guard against virus diseases, consider the following measures:

1. Purchase certified virus-tested or virus-free plants.

2. Maintain strict insect and mite control.

3. Control weeds because they may harbor viruses, mites, nematodes, and insects.

4. Destroy virus-infected plants.

5. Disinfect pruning tools by cleaning them with rubbing alcohol, drying, and spraying with a light coat of oil to prevent rusting.

    "As the promise of spring begins to beckon the attention of "dormant" gardeners this time of year, so it is with those dormant weeds that will appear soon enough, making for a lot of catch up work to get our lawns ready for show time," says local Master Gardener Trainee, Bernice Pitt who has just completed certification in an NC State University course in Turf Management.  Pitt is manager of the lawn and garden center at Marrow-Pitt Ace Home Center in Tarboro and is ready to help you with solutions in
    maintaining your lawn.  "I have found that the best source for answers to questions regarding turf grasses is the site:
    www.turffiles.ncsu.edu and another,
    www.turfweedmanagement.ncsu./weedmanagement.aspx," Pitt added. "It's where we found answers to this week's questions."

  • Filbrun 2.jpg Sanitation: An Important Garden Chore

    So, what will tomorrow bring?  At this time of year, we are riding the roller coaster up and down as winter and spring duke it out.  While it is still too early to start most seeded varieties of annual flower and vegetable varieties, it is not too early to prepare for the upcoming gardening season.

    John W. (Tarboro) Asks: A neighbor posed this question to pass along. They did nothing to winterize their yard and, as a result, have all of the winter-type weeds that survive everything. They wanted to know if there is anything they can do now to kill off the weeds and what and when do they start to try and green up their yard and kill back weeds as we head out of winter.
