How do I know when my Dendrobium has finished growing?
Dendrobiums make tall, cane-like pseudobulbs with leaves all along the length of the cane. When the cane has reached its maximum height then it makes a ‘terminal leaf’ at the very end which signals the end to its length. The cane often then still has to swell a bit more and when the sheaths around the cane turn papery then it has done al the swelling it is going to do. This usually happens in autumn and at that point you can start to reduce the watering.
