A Peach of an Orchid


******************************************


    I have been asked to describe how I grow the Masdevallia 'Peachie' seen on the plant table during the September MOS meeting , so here it is. I have been trying to obtain a sample of as many different genera as I can, just to see what I can and can't grow. I had wanted to get a Masdevallia for quite some time because they have many desirable qualities; they are small in size, have quite unusual flowers, don't need a lot of light, and are not too expensive.

    I adopted this plant as my first Masdevallia at our Palm Sunday show this year from D&M Crawford out of Murraysville, PA. This primary hybrid is a cross between a pink form of M. floribunda and M. triangularis. Both parents are reputed to be intermediate temperature growers so I figured that this plant would have that and 'hybrid vigor' going for it. It was, and still is, potted in a very small clay pot with what appears to be straight osmunda as the growing medium.

    It has spent most of its time sitting on the windowsill of a small west-facing basement window (with low-e coatings, no less, which have been described in the past as 'death to orchids') which gets only very limited direct sun in the summer just before the sun drops below the horizon. In the winter, as the sun sets further south and is blocked by part of the house, it gets no direct sun. At night during very cold weather, it is moved away from the window to the interior of the room to protect it from freezing.

    The house heat is controlled by an electronic thermostat that drops to 62 F at night and as high as 73 F during the day. The temperature on the windowsill varies from the mid 50s at night to perhaps 65 or 70 F during the day according to my Radio Shack electronic min-max thermometer/humidistat. In the summer, the temperatures were from 65 F at night to 75 F or so but I think that the temperatures, for the most part, were cooler this year than average and we didn't have any long spells of very hot weather.

    Humidity is generally from 60 to 80 %. In the winter, the console humidifier for the house runs nearly non-stop just below the window where the plant lives and it definitely keeps the air moving. Humidity is also enhanced around the plant by placing the pot into a yogurt cup (Glenda, it was Blueberry !) lined with carpet pad. The overspray from misting or drenching is caught in the cup and is wicked up through the pad to make contact with the pot. This is also useful as a reservoir for long weekends away when the plant would not otherwise be watered.

    It is watered with reverse osmosis purified water purchased from the local grocery store and carted home in two 2.5 gallon reusable jugs (it's not my only plant). The fertilization has been haphazardly done with Dyna-Grow Bloom at the recommended rate or less.

    While I am sure that these conditions are less than optimal, they seem to be working. The plant was in bud, unbeknownst to me at the time, when I got it and has been in bloom for most of the time with as many a six open flowers at one time. I only hope that its recent sill-mate, M. kuhniorum from Oak Hill Gardens, does as well...
