Do orchids bloom on the same stem?
Considering this, do you cut the stems of orchids after they bloom?
After the flowers drop from the orchid you have three choices: leave the flower spike (or stem) intact, cut it back to a node, or remove it entirely. Removing the stem will direct the +plant's energy toward root development, which makes for a healthier plant and increased chances for new bloom spikes.
Consequently, do you still water orchids after flowering?
After orchids stop flowering, they need a rest period before they resume flower production. Phalaenopsis and Vanda orchids don't have pseudobulbs to store water, so you should water them thoroughly when the potting mix is nearly dry to keep them from completely drying out.
Once you're done watering your orchid, place it near a cool window and fertilize with 20-20-20 solution, once or twice a month. This is another important step when getting orchids to rebloom. Your orchid rebloom should happen 6-9 months after resting.
