Oncidiums Comments
ONCIDIUMS: Breeding Characteristics 18 oncidiums, species and hybrids, rated for a projected attempt at improvement of Oncidium Goldiana (Golden Shower) by eliminating virus; 13 criteria applied, pointing to perfection; refer to OD80-45+ 0
ONCIDIUMS: Cool Growing Onc. macranthum and its allies of the Cyrtochilum section, including Onc. superbiens, serratum, falcipetalum, lamelligerum, anthocrene, monachicum, and leopoldianum; they grow cool to cold in Colombia and Peru; a mild to strongly acid medium is recommended. OD71-147+ 0
ONCIDIUMS: Equitant Types A cultural hint on how to grow them in Tennessee in a small pot on one lump of charcoal. OIE85-5They will not flower, possibly when they are over-fertilized, so the feed rate should be halved. A83-698 0
ONCIDIUMS: Flowering Excessively If you can believe it, some have a tendency to flower themselves to death (not in my greenhouse) without showing signs of failure, so cut off the spikes after several weeks. SA85Mar-53 0
ONCIDIUMS: Good Pollen Parents Those showing male preference in hybridizing as against being the pod parent; 18 plants listed; refer to OD77-101 0
ONCIDIUMS: How to Grow Them General cultural directions for most types; refer to A79-334+ 0
ONCIDIUMS: Sexual Compatibility Groupings 58 species arranged by name in four groups on the basis of sexual compatibility for breeding; six other genera grouped on the basis of their compatibility with oncidiums; much other breeding data; refer to A64-1035+ 0
ONCIDIUMS: Watering Many oncidiums dislike heavy watering; they need a decided reduction except when in full growth. OR75-209On repotting the mix should be open and only a sniffle of water applied, no more is necessary; mule-eared types reserve lots of energy in their massive leaves; let the roots develop so they will be full when needed; many come from areas of little rain, or long dry periods. OR85-136 0
