I feed all my CP (Heliamphora, Sarr., Darlingtonia, Drosera,
Nepenthes, Cephalotus) a solution of fertilizer at 1/3 the
recommended strength. I do try to avoid fertilizer with extra
calcium or copper as I have heard that these are poisonous to
Heliamphora. I recently tried an "experiment" of increasing the
strength of the solution; at about 50% recommended dose the
Cephalotus began to suffer, and at about 66% the Heliamphora
also began to suffer (leaves were browning early). I should
mention that I increased the strength over a period of six or
seven weeks, I honestly believe that the plants would have been
damaged much more if started on the higher doses right off the
bat. I DID NOT include Drosera in the experiment and I also do
not feed them that often. In the past I have introduced pebble
sized pieces of fertilizer 20-20-20 right in the pitchers of
adult Sarr. Purpurea without ill effect. I never feed the plants
by spray, I have but that seems to benefit the moss (not
sphagnum) more, but with an eyedropper. The amount being placed
on/in a plant can be easily controlled.
