I fertilize once a week with 1/4 the recommended dose, during the summer. In the winter I use the same strength once every two weeks. If the orchid is in an open medium like fir bark you can water with the fertilizer. For orchids in sphagnum moss I use a hand sprayer and I spray the fertilizer on the leaves, visable roots and the top of the sphagnum. I wouldn't pour fertilizer mix in sphagnum moss because it will absorb too much of it and the salts will build up. Also flush the pots with plain water once a month to remove accumulated fertilizer salts. I would rather give an orchid too little fertilizer than too much.
