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: 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: Terete-leaved Lost their new grewth through rotting and blackening which may have been caused by daily (excessive) watering or because of Phytophthora or Pythium fungus,neither of which are affected by the spray used, benomyl. A82-487 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
