Temperature
Miltoniopsis should do well in the average home or intermediate greenhouse. A night temperature of 58-64 F. and a daytime temperature of 70-80 F. is considered best. They will tolerate higher or lower temperatures, but not for extended periods.

Humidity
If you keep your Miltoniopsis well watered, humidity is not a critical factor. However, try to keep humidity above 50%.

Watering
Miltoniopsis like to be kept fairly moist with a slight drying between watering. Frequency of watering is affected by pot size and air flow: during warm dry weather this may be 2-3 times a week, during cool weather 1-2 times a week depending upon pot size and air flow. A sure sign of under watering would be the formation of accordion-pleated leaves. If this happens, increase watering slightly.

Feeding
Prior to fertilizing, water plant with clear tepid water. Dyna-Gro is the ideal brand to use as it provides all six of the macro nutrients and all essential trace minerals plants need to be healthy, grow and flower. Mix 1/2 tsp. of Dyna-Gro Grow with one gallon of water and use with every watering. To assist blooming, switch to the low nitrogen/high phosphorus Dyna-Gro Bloom formula or Mag-Pro supplement for the winter and/or pre-bloom periods.

Potting
Miltoniopsis do well in a mix of medium coconut chips, charcoal and coarse spongerock. It is important that the pot drain well. Miltoniopsis like to be somewhat potbound so allow for only one year's growth. Repot each year in the spring.
