Watering

These orchids prefer a constant supply of moisture, with a slight drying out between waterings. Saucers can be placed under pots to retain moisture during hot weather, however the saucers should be removed or let to dry every 1-2 weeks to prevent rot. Keep an eye on the plant especially in hot weather and look for cues of under/overwatering and adjust accordingly.

Fertiliser

These plants do well with slow release fertiliser at the rate of 2-3 pellets per cup (250ml) of media. Additional fertiliser during the growth period may be beneficial, but not necessary.
