But it depends where you are and what your water is like, (pH and soluble solids) to determine what kind of fert you should use.

Also important is what kind of orchids your wife has, and where she is growing them. (indoors, outdoors, in a greenhouse?)

Many thanks to all who answered my SOS for fertilizers for orchids. To answer a few questions: we live in a residential village 25 miles from the seacoast near Recife in northeast Brazil. My wife has only recently taken to raising orchids (catley etc), some grown outdoors under shade and some indoors. Buying commercial mixes like Dynagrow etc, from Amazon thru internet is complicated due to brazilian custom restrictions on shipment of chemical substances. Common fertilizers like NPK, epsom salts, copper sulphate are easily available. Water supply is from a deep well pump (85 meters deep).
