foliar feeding

[tmoney]

hi folks,

as we expand our knowledge and expeience with orchids, the topic of foliar feeding is one that has come up several times, including most recently in our conversations with a much more experienced grower.

in regard specifically to phal gigantea and doweryensis, it seems like the pros do foliar feeding. i always thought the nurseries did it for ease and efficiency sake.

so, the question is, is it really necessary? our plants seem to be doing good overall, but if it helps a couple plants grow better than i am willing to try.

can we use the same concentration we have been using for root zone feeding? should we add a drop or two of soap as i read is often suggested as a binder of sorts?

thanks for any info hivemind!!
