It's so true that the first reaction of a collector is to think Oh My Gosh, I may lose my other plants! I think it's the threat of the unknown that sends most newbies into that first HVX panic. I had my moments when I first found it in my garden. My way of not panicking was to find information.
Those who have been through it once or twice and understand it is something that can be controlled are much less likely to worry. However, we all must remain diligent and do our part to educate others, including nurseries.
