Miltonia regnellii

The water needs of these two genera also differ although watering for both may be decreased during the grayest periods of winter. Too much water without at least some sun can lead to root rot. Let the medium for Miltonia (Brazil) to dry out before a thorough watering. Be sure to drain any excess. Miltoniopsis prefers a consistently moist but not wet medium. It's best to water orchids in the morning, giving them a chance to dry out before nightfall.

Both Miltonia genera require cool night time temperatures of 55 to 60 degrees in order to bloom. Miltonia (Brazil) thrives in day time temperatures below 80 degrees but will tolerate up to 90 degrees for short periods. Miltoniopsis needs cooler daytime temperatures of around 70 degrees. Moderately high humidity between 50 to 70 percent works best with 60 percent humidity being ideal.

Feed Miltonia orchids once a month during peak growing and flowering periods, and skip fertilizing during winter months. Many orchid food products are commercially available (Miltonias are not fussy about fertilizer). Miltoniopsis is sensitive to salt, so it's advisable to flush the growing medium with just water after several feedings. If your tap water has a high mineral content you may want to filter your water or use distilled. Use room temperature water whenever possible.
