Are these another type of scale ?
Hello everyone. Pretty strong wind knocked my orchid pots down and i have to repot them, then i saw these things. They look alike scale but not round shape, i can scratch them away using finger nail. I had some different types of orchids and these things only appear on my dendrobium. Hard to tell if there’s any damage from these things to the orchids after a very cold winter because my den. orchids grow very very slow this period. Anyone had these things before please ?
