Gravel Culture Comments
GRAVEL: As Potting Medium Quartz stone is a good substrate for Cattleya lablata and many encyclias; it needs more watering than bark and a periodical fertilization. OD87-147 0
GRAVEL CULTURE: Comparative Merits Phalaenopsis do very well, cattleyas not so well as in osmunda, mexi-fern or bark; much used around 1950, now confined to phalaenopsis; takes more labor; more problems with bush snails. A65-1003+ 0
GRAVEL CULTURE: Of Phalaenopsis It will not produce one more flower or leaf than will bark, or osmunda, etc. under good culture. A81-393 0
GRAVEL CULTURE: Pebbles One grower favors them for a collection of epiphytic orchids. OA82-7 0
