Fertilizing Comments
FERTILIZING: Cattleyas, When to Stop The idea that it is good to stop fertilizing at some point is a myth; plants at rest do not need fertilizer but it does no harm to them; 30-10-10 or 20-10-10 are better than 18-18-18 for steady feeding. A73-338 0
FERTILIZING: Enhanced Feeding If properly controlled it produces more and larger flowers. A73-909+ 0
FERTILIZING: Of Cattleyas in Bark Use 1/2 to 1 tpg of 30-10-10 every second watering all year round. A81-1093 0
