Rose rosette

One rose bush out of seven in my garden contracted rose rosette. I removed the bush and surrounding soil. None of my other rose bushes appear to be effected. I know also, that it is difficult to grow a new rose bush where another has been UNLESS all the soil is removed and replaced. I have dug out about a 2X3 foot hole about 1 foot deep. I have removed all roots. Is this enough to plant another rose bush in this location? I know ii is risky but just want to know how much dirt to remove.

NO! I just came from the DSD/Carolinas Mid Winter Meeting. Dr. Windham spoke on RRD. The virus CANNOT live in the soil. So after 7 days (the mites can't fly and can't live past 6 days) you can replant in the same soil.

For bacterial issues like gall, you do have to remove the soil because the bacteria can survive in the soil.

It's not the problem of virus living in the soil so much as leaving roots behind after a dig out.

The virus can live in the roots that might be left behind.

Root to root transmission of viruses in rose bushes has been proved by Giolino and others (and it's published in refereed journals). It hasn't been proved to happen for RRD infected roses, yet. But I have seen that infected roots of very large roses can put up RRD infected roses several feet from the dug out bush, when we thought we had dug out all of the roots.

For a two or three year old rose, the root mass probably isn't going to be massive. But do leave a little time for the roots to come back. (See all the Dr. Huey that comes back when we've dug out what we thought were all the roots.

Ann, Dr. Whitcomb said that if there were roots left, they could not graft or spread the virus to the new plant. I'm just going by what he said. Of course you have to try to get all the roots and it may be a good idea to wait to see what comes up (especially if it's Dr. Huey rootstock).

BTW, I met some members of your society. Sorry you couldn't make it.
