Will Orchids rebloom from the same growth?
Usually Not in the same year. Some Dendrobiums will rebloom from previous bloomed “canes” in their next cycle. However, the phalaenopsis — the moth orchid — can be induced to rebloom from its old spike. If you cut the flower spike just below the old spent flowers and above the last node (covered with a small triangular brown sheath), you may get a reblooming from one of the lower nodes. Always cut with a very hot instrument, to seal the cut, and cover the cut with a fungicide.
