When is it safe to bring orchids in after spraying with fungicide
Today I sprayed several orchids outside with OHP 6672, formerly Cleary's I believe. How many hours should I leave them outside before bringing them in? It's supposed to be about 30 degrees tonight in NC. They're phals, catts and oncidiums.
I'm thinking about bringing them in now, 3 hrs. after treatment, and placing them in an empty bedroom with the door closed.
Thanks for any advice you can offer
