TERRESTRIALS, NATIVE: Formula for Potting Soil For Australian terrestrials a good mix is made up of 50 to 60% of sharp, washed river sand, 20% German peat, and 20 to 30% of decayed Eucalyptus leaf litter, or sawdust chips. A77-984For U.S. types, people aften transplant in the original soil; but more than that is required for cypripediums; for experiments with artificial bogs, refer to A76-415+; transplant the mycorrhizal fungi and the condition they require.

TERRESTRIALS, NATIVE: Potting Medium For Australian types, the Canberra Botanic Gardens mix is 50 to 60% sharp washed river sand, 20% German peat and 20 to 30% eucalyptus leaf litter or sawdust chips; use plastic pots, cold frames 25 deg.C. AU77-139 0
TERRESTRIALS, NATIVE: Suitable for Garden Growing Besides Epipactis helleborine there are many others; a fine recommended book is W.H.Gibson: Our native orchids (1905); refer to A73-6874-; A76-206; for practice in Germany, refer to OR77-340+ 0
TERRESTRIALS: Native U.s. Types Ensuring seed fertility = refrigeration is the key to success for Cypripedium reginae and likely others; refer to A87-935Formula for seed germination = developing embryos in flask sometimes turn black and die on a scientifically prepared media; for other formulae try Orchid biology II (ed. Arditti), the Appendix on seed germination. A84-1181 0
TERRESTRIALS: Problem Plants Use plastic pots, broad based, but half as high as most; repot any time during dormancy and carry over about one-third of the old compost to transfer the mycorrhiza; dormancy comes after flowering not in the fall or the winter as expected, so water lightly in summer, carefully in winter; practice at Kew; refer to OR87-19 0
