Also remember that each species or hybrid has its own genetic characteristics.
One of my aggressive growing Catleya is Little Stars x Maikai.
I have one that is growing 7 yes seven new pseudobulbs at one time (a 2 inch pot repotted to 4 inches in the fall.) and I have another that looks like yours doing nothing yet. With patience it will start again. Be careful not to over water when it is at this stage
