I was reading that for good blooms one should stop fertilizing nobile type Dendrobiums in early August. I grow mine outside and we’re coming into the warmest part of the year, and mine have finally put on a real growth spurt with new young canes starting to push up. They even decided to flower a second time with the buds just opening this week. Should I really stop fertilizing now?
I can't speak from personal experience but someone told me to go by the plant rather than the calendar. If the plant is growing quickly keep fertilising. Besides, the plants react to weather conditions so while you're warming up we, in the UK, have started the slide into the Autumn, with warm days and much cooler nights so the way I have to work with my plants will differ from yours.
