Hosta Virus X has no cure

Two summers ago, I noticed some mottled leaves on a hosta, the “ Sum and Substance ” diverseness, growing in my garden. It could be a genetic variation, it was not unattractive. I decided to wait and see. The master Hosta “ Sum and Substance ” was introduced in the 1980s. It cursorily became democratic among american gardeners, and was the most talked-about specimen for the shade garden. Why ? Because it was very bombastic, growing to a 4-feet-by-9-feet outspread. subsequent dimensions ( in 2005 ) are slightly smaller, but it still makes a huge impression in the landscape.

“ Sum and Substance ’ ’ has been used successfully in many breeding programs. meaning sports, or mutations, have besides been generated, appropriately entitled “ Sum Total, ” “ Sum It Up, ” “ Sum Like It Hot, ” and many more. Leaf color mutations occur in hostas frequently, and when the mutant leads to a stable color combination, the result implant is called a “ sport. ” I was hoping I had found such a fun, but that was not to be. Hosta Virus X ( HVX ) was beginning described in 1996 at the University of Minnesota. HVX is a potexvirus that is spread mechanically by any means that will move the plant fool from an infect plant to a goodly implant. so, it can happen when you are dividing the hosta, or when you are cutting the flower stems, or by good stepping on a plant or its leaf debris. The still of infection, coupled with a bankruptcy to recognize the symptoms, has caused a rapid circulate of the disease. The earliest symptom to appear, and the one that is park to about all infect hostas, is called inkbleed . This is a bleed of color along the veins of the leaf and a bluish green mottle of the flick surface. Another symptom, collapsing weave , is a sign of a heavier infection. The flick weave may look as if all of the water was removed from certain spots. The leaves may appear lumpy or puckered. Less common symptoms include dried, brown university spots and twisted, deformed leaves. These symptoms vary depending on the cultivar. A gold, chartreuse leaf, such as that found on “ Sum and Substance ” will often have inkbleed mottle, and the bluish green mottling is promptly visible. other popular gold-leafed varieties such as “ Golden Standard ” and “ Golden Tiara ” are besides highly susceptible to HVX. Of the blue-leafed varieties, “ Blue Cadet, ” “ Krossa Regal ” and “ Patriot ” are considered highly susceptible. I have had all of these hostas in my garden, and all were contaminated finally after the initial contact with “ Sum and Substance. ”

At this time, no cultivars are either immune or repellent. Some plants may not display any symptoms. This may happen if they have become infected only recently. If you any have plants with HVX in your garden, treat all plants as if they are carrying it. There is no cure for Hosta Virus X. This plant needs to be in full removed from the garden and disposed of with trash. It is not compostable. The virus does not persist in the dirty, so you can replant immediately in the lapp area. just be sure you have removed all of the roots, leaf debris and flower stalks of the infect plants. then sterilize your tools by dipping them in a 10-percent bleach solution and thoroughly wash your hands before working on another plant. As dwelling gardeners, it is important for all of us to be familiar with the symptoms of this disease. Take natural process if it is in your own garden. If you observe it on a particular kind of plants in a nursery, do not purchase any early plants in the same lot. “ The Hostapedia, ” by Mark Zillis, lists over 7000 types of hostas — those that grow well in sunlight or ghost, are big and modest, are fragrant or not, are textured or not, and in every shade of green conceivable. The hosta is highly esteemed by american gardeners, and everyone can play a character in the eradication of Hosta Virus X. Ann Auerbach is a Rutgers Master Gardener in Camden County.
