Foliar Feeding

[Orchid Whisperer]

The utility of foliar feeding may be low for some types or orchids. Any orchids with a thick waxy cuticle, like Phalaenopsis or Cattleyas, probably won't get much out of foliar feeding. Maybe it would work better with thin-leaved genera like Oncidium or Ludisia?

I usually assume that most nutrients need to get into the plants through the roots, and apply nutrients accordingly.
