The second Cattleya has ORSV .
Now I will probably spend the whole night worrying about infecting the first one. I’ve only had the second one maybe a month and it spent little time in my greenhouse so hopefully it didn’t spread anything. That said, it did have sap on the surface since it is growing a new lead. Not to mention, I have a lot of splashing water in my GH… |
I have plants in my collection for years with ORV and others with cymMV. I used to water all my orchids by submerging plants in a sink full of water, and it didn't seem to spread it. In fact, the number of infected plants in my collection was much lower than the number of infected plants recently arriving from sellers (both on and off eBay).
I think you can be certain that the virus doesn't travel through a plant fast enough that removing an inch wouldn't be far more than was necessary.
Rather than flaming, which I've also used successfully, I suggest buying single edged razor blades. You can find them on Amazon for as little as a nickle each.
