I dunk my plants with fertilizer, collect the runout from the pots and use it to fertilize my other orchids in a similar fashion. I save a lot of fertilizer this way. Is it alright to do that?

Dunking is one of the best methods of fertilization since the entire media gets wet with fertilizer thoroughly; however, if the runout is used to fertilize other orchids, it would be the easiest way to transmit diseases including viruses from one plant to another. Dunking can also become difficult if you have a large collection. The easiest way is to use a hand-held sprayer or a motorized sprayer, and spray the leaves as well as into the pots until fertilizer begins to run out of the pots.
