Intergeneric Oncididnae love humid environments. Water two or three times a week and allow the plant to drain completely. You cannot over water these plants. Misting will help make your orchid happy, especially in dry climates. Place plants in bright indirect sunlight. Use a dilute foliar fertilizer with each watering or place a good quality time release fertilizer, such as Nutricote or Osmocote in the pot and note the manufacturers recommendations as to how long the fertilizer should last. Intergeneric orchids don’t mind being crowded in the pot, but when you do repot, use a media that drains well and has plenty of air space. 50% commercial orchid bark mixed with 25% large perlite and 25% coarse peat works well. You may divide pseudo bulbs to propagate your orchid if you like. Some intergeneric orchids will bloom any time of year, but many are specific, such as spring or fall. Note the time of year your plant was blooming and expect it to bloom again the same time next year.
We suggest you replant your orchids after arrival. A 6 inch azalea pot works well, and you can use the media mentioned above, or simply place your orchid in the pot and pour washed gravel around it.
