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.
