Hi,
My boss is a big fan of orchids, he has 4 phals, and I've seem them all bloom and rebloom in the 2 years I've worked for him, and for the 1st year I was responsible for watering and taking care of them in general and they were nice, firm and blooming. Last year he hired one more assistant, and taking care of the orchids was her responsability now, and they were pretty good. 2 weeks ago, the new assistant got moved to another department, so the orchids are my responsibility again, and ever since, 3 of them are losing the flowers alarmingly, I am attaching the before (full blooms, taken about 3 weeks ago) and the current state of the orchids, 3 of them have lost most of their blooms, (all but the purple one, that is keeping a good shape and all its flowers). Do orchids "feel" or resent the person who's watering them? What can I do to save them and bring them to bloom again?
I must add that I taught her how to water the orchids, the frequency,quantity of water, when to feed them, etc. so I have no idea what is going on and I am so sad
