Phalaenopsis Black Roots After Repotting: Bad Media, Red Water, and Emergency Media Switch

Question:

Repotted Phals 3 days ago. Now roots black, dry, spotted. Media colors water reddish. Another transplant needed? Media too nutrient-strong? Soaking in water now. What media to choose? Bought from Orchid Accessories online.

Answer:

Hi Agnieszka,

Unknown Orchid Accessories mix contents, but it's making Phals unhappy. Repot using primarily medium orchid bark + large perlite/sponge rock.

Until new bark: thoroughly wash current media with lots of water to remove reddish color, use remnants to repot temporarily.
