Growing attention is being given to "Hosta Virus X", as it is apparent that is not limited to one area of the country. Hosta affected by virus are present in shipments by major vendors to varied garden centers. Regional hosta experts have reported seeing signs of Hosta Virus X in plants at a number of upstate NY garden retailers. Depending on the coloration of the varieties' leaves, the signs of Hosta Virus X may be apparent or tough to detect. Definitive tests in the laboratory are the only way to positively identify if the plant contains the virus. Below, normal and virus-affected leaves of hosta.

Plant material at an upstate NY store may originate overseas and be part of an infected lot. Hosta grown locally as cuttings from infected plants may carry the virus. Garden retailers are becoming aware of Hosta Virus X as a problem, and will grow in understanding of the causes and symptoms as time goes on.

Existing plants in a garden may acquire the virus from newly-purchased plants located near them. Gardeners must carefully examine hosta for healthy foliage before buying new plants for the garden. Care should be taken to avoid transferring virus from new plants to established hosta, typically through weeding or pruning. Garden tools should be sterilized using isopropyl rubbing alcohol or a solution prepared from one part household bleach to nine parts water.
