I was surprised you had a mounted Nobile dendrobium. They look so good in pots that I seldom mount them. It is just a matter of ascetics for me. I have mounted them on request for customers and did not have any problems.
I assume you have a hybrid Nobile and not the species. It is what is most available, although, South Africa may be different.
The hybrids are easy to grow so you have a lot of leeway in its care. Species are recommended to have severe drying out periods.
I find the Yamamoto Hybrids I handle can take full sun all day long without shade and flower in shade as well. They can take a lot of water year round and should not allow their canes to shrivel from lack of water, but can go long periods of drought. I advise they have a temperature range of 32-100 F (0-100C), but recently froze some to under 25 F and they did not even drop their flower buds. Be conservative with fertilizer. Too much Nitrogen causes keiki growth at the expense of flowers. I recommend no fertilizer after August until flowers bloom in the winter.
