My oldest Orchid (an Oncidium Sharry Baby) is taking a dive! I've had it nearly two years - no flowers. Now it just looks sick. The psuedobulbs look fine but the leaves look very dry even though it has been watered regularly. The leaves also have turned splotchy brown on the undersides (it is not in direct sunlight). When I gently rub the leaves a rusty colored powder comes off on my finger. Any new growth has withered up and died. Only the oldest growth still remains. Any suggestions or will it soon meet my garbage can?
