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
FERTILIZING: Paphiopedilums Dissolve six ounces of a 30-10-10 soluble fertilizer, or eight ounces of a 21-7-7- in 100 gals of water and apply monthly; or at 1/2 strength apply fortnightly. A72-631 0
FERTILIZING: Signs of Over-fertilizing The plants are usually lush-growing, dark green with lots of leaves and no flowers; just like my Encyclia vespa. A84-129 0
FERTILIZING: Using a Plastic Drum for Holding A 200 litre size container with piping, a valve, filter and pump to dispense premixed Aquasbl feed; refer to AU86(2)-19 0
FERTILIZING: Vandas For organic, use fish emulsion; for inorganic, use 30-10-10 or 20-10-10 at two to three teaspoons per five gallons water; do not reduce nitrogen proportions, just keep amount per application low. A65-152 0
FERTILIZING: With Every Watering It is not advised; use 1/2 tpg. of 30-10-10 at every second watering. A72-905 0
