Why roots do not look healthy anymore?
I have three, about 5 years old phals. During last a couple of months my roots become to change from green silver "fat" to dry, wrinkled, brownish.
They do not look healthy anymore.
Three months ago I re-potted all of them, removing rotten parts, and change the soil (orchid soil that looks like chunks of barks) - but it didn't help at all.
All leaves are green and looks healthy.
What happen to my orchids - what to do?
Thanks in advance
