|---|---|
| CORK: As Mounts for Cattleyas C. aclandiae, C. walkeriana, C. nobilior, and C. schilleriana, all Braz ilian bifoliates, grow on fissured bark or moss-covered rocks in a pronounced wet and dry seasonal change; cork allows roots to attach themselves to it; drains well, sheds salts from around the roots. A87-359 | 0 | 
| CORK BARK: Growing Medium Ground up into small pieces, sold as cork chips or cork nuggets, it is a satisfactory substitute for bark in some places; as slabs or mounts it accomodates many species of epidendrums, oncidiums, small dendrobes, cattleyas and others; refer to A86-495 | 0 | 
| CORK BARK SLABS: Artificial or Molded Used as large slabs for insulation of refrigerated rooms; can be cut up and used as mounts; the binder or adhesive is non-toxic to roots and holds up to watering; surface rough enough for root adhesion; recent decorator slabs may have toxic binder. A65-111 | 0 | 
| CORK BARK: What Orchids Grow on It? Many epidendrums, oncidiums, small dendrobiums, and cattleyas will grow on cork slabs; ground cork pieces, if medium bark sized, can be used instead of bark but they hold less moisture than fir bark. A70-1018 | 0 | 
| CORK BITS: As Potting Medium Fertilizers that might be appropriate for this would likely be balanced ones (20-20-20) because cork is relatively inert and does not tie up nitrogen like bark does. A85-866It is normally slow to decay and if mixed with charcoal should not break down into a humus-like mix in six months or so, although compressed cork particles might do so. A85-;92; RMH | 0 | 
| CORK BITS: For Potting Cattleyas Tree-fern is preferred over cork bits usually; cork slabs need osmunda, sphagnum moss or tree-fern pads to start the roots. A80-960 | 0 | 
| CORK BORERS: Insects Bore Into Slabs and Corks They leave a dusting as evidence of their inroads; they attack corks in storage; spray with Malithion where the holes appear in the slabs; for corks, place them in a plastic bag with some insecticide powder and shake. AU84-127; RMH | 0 | 
| CORK CHIPS: As Potting Medium They dry much slower in the pot than cork slabs in air and seem to decompose in less than a year in hot areas, so repotting at regular intervals is a must. F82-55 | 0 | 
| CORK: For Mounts Mosses and lichens found on a piece of bark at time of purchase should have no ill effects on a plant, but can be easily removed with a wire brush. A87-818 | 0 | 
| CORK NUGGETS: Available in Five Grinds Description and claims of the producers; refer to A84-1084 | 0 | 
| CORK NUGGETS: Culture Tips In South Florida they decompose rapidly so repotting must be done more frequently; tree-fern, charcoal, fir bark and even sphagnum moss are better alternatives. F84-179 | 0 | 
| CORK NUGGETS: Fertilizers for Use 10-10-10 because oak bark is inert, A85-726 | 0 | 
| CORK NUGGETS: Mixes with Charcoal Up to 5 in. pots use medium nuggests with #3 charcoal, to 7 in. pots with #2 charcoal, to lO in. pots, coarse grind with #1 or #2 charcoal. A85-369; distributer listing A85-101 | 0 | 
| CORK NUGGETS: Potting Medium As potting medium = breakdown in the pot in hot countries is its main problem. OIE86Jan-15 | 0 | 
| CORK SLABS: For Mounted Plants It is better than redwood, cedar slabs, oak branches or tree-fern; it cuts easily and plants can be tied to it with nylon fishing line, six to eight pount test, or for very large plants, nylon stockings. OIE85Nov-12 | 0 | 
| CORKS, WINE: As Potting Medium When cut up in pieces the size of medium bark they are good for many genera; whole corks or half-corks cut lengthwise and nailed to a flat of wood make excellent mounts for species with some moss added; vandas do well in corks; they last well. ODA74; RMH | 0 | 
| CORKS, WINE: Recycled, as Potting Mix Whole corks are useful for potting thick-rooted vandaceous plants, are good for drainage when pebbles are used in the bottom of the pot, they maintain a coarse open space when mixed with charcoal pieces or coconut fiber; roots attach to corks; show no preferences for vintages or country of origin. A83-1173; OIE86Jy-9; not likely to carry virus. A86-719 | 0 | 
| CORK TILES: Pressed, Commercial Sheets Can be used as mounts for equitant oncidiums; cut in strips 2" by 12", and place four plants on each strip with a thin pad of sheet moss or coconut fiber and tied with bits of nylon stocking. A86-677 | 0 |
