Dear Glen,
Welcome to PBS. I live in Gresham Oregon and have a small bed devoted
to terrestrial orchids. I also have an all season greenhouse with some
epiphytes. The former are partly purchased but many are small clones I was
able to harvest during my work at University of California at Davis
Botanical Conservatory. The Botanical Conservatory was not geared for
growing on small sections of orchids. It was a teaching conservatory. A
Cattleya division has to be at least 5 - 7 pseudobulbs in order to expect
blooms following repotting. Sometimes, there were small divisions left over
(2 to 3 pseudobulbs) and I was permitted to take them. LT 5 but GT 2 might
be potted for the annual plant sale. Otherwise, they would be discarded and
put in the university compost beds.
Best wishes, Joyce Miller, Gresham, Oregon USDA 8.
