Newly purchased onoine Cattleya, diseased need refund or not?

[orchidhope]

LOUIS,

I suspected you were talking about the hardening of the spot and I had done some reading that could be from a scrape or cut. I'm beginning to think chemical companies are putting fear into us about black rot and I overreacted.

The online orchid arrived in a smallish bark medium, I topped with moist New Zealand Sphagnum moss to encourage rooting and I am spritzing that top moss daily. I did not repot because I have read Cattleya roots are some of the most sensitive of orchid species. I had also read that Cattelyas like to dry out completly between watering so not rushing soaking the bark, which when I water I will submerge it entirely below leaves on stem with fresh tap water for 8 minutes. (Florida Keys, decent water quality and have a whole house water filter.). Since it arrived 7 days ago I have not rewatered and it is in a shaded area for root growth rather than dappled sun for leaf growth. Rather a newbie at this but applying myself with more research every day.

Thanks again for your help.
