Rock's Nurseries after 1884

1887 San Jose Directory

There seems to be the general assumption that Rock's Nurseries was consolidated into the California Nursery right away in 1884. 

But it makes no sense that you would uproot all of your nursery stock in San Jose and move it to Niles. Wouldn't it make more sense to keep both properties and sell the Rock's Nurseries stock from both catalogs until there was no more? I have followed this transition for a while. There was a messy divorce in the midst of all of this and probably some issues with this break-up.
Lots of information can be gleaned from the San Jose Directories.
