TEMPERATURE – Miltonia should do well in the average home or intermediate greenhouse. A night temp of 60-64 degrees and a day temp of 70-80 degrees is considered best. They will tolerate higher or lower temperatures but not for extended periods.
LIGHT – Miltonia requires a rather low amount of light (1500 to 2000 foot candles). If grown in the home, recommend an east or west exposure or south with shielding from direct sunlight.
WATERING – Miltonias like to be kept fairly moist with a slight drying between waterings. During warm dry weather, they may need to be watered 2-3 times weekly. During cool weather, 1-2 times weekly. A sure sign of underwatering would be the formation of accordion-pleated leaves. If this happens, increase your watering slightly. Miltonias have very tender and fragile roots; for this reason, we recommend using rainwater whenever possible.
FEEDING – Since Miltonias are vigorous growers, fertilizer can be applied almost every watering during the spring and summer months. This should be reduced to once weekly during fall and winter. We recommend 1/2 strength solution of 30-10-10 fertilizer with each application.
HUMIDITY – If you keep your Miltonia well watered, humidity is not a critical factor. However, try to keep it above 50%.
POTTING – We find Miltonia do well in a finer grade of Fir Bark mix. It is, however, important that the pot is well drained. Miltonia like to be somewhat pot-bound so allow room for only one year’s growth. Repot once a year in the spring.
