I am new to orchids. My orchids passed quite rough time spider mites and root rot. I repotted two of my orchids in new bark medium. Today while watering my phals I notice that roots do not looks so good. both of them have one or two roots left. If they are left without roots can I still save them ?
here are some picks how they looks like and how I keep my phals
Are you talking about your orchids not having aerial roots? What I see in your photos are nice looking orchids. Did you take them out of the pot and find the roots are mushy?
Sorry what I meant is bottom roots. I repot them because I notice that some roots looks rotten. removed from old bark medium and cut all the mushy roots. I ended up with one or two half roots. I clean and disinfect them and put them in new bark medium. The leafs might look good but I can see slight difference that they getting worst by the day. I also use fertiliser in the water hoping it will prompt new roots but I am not sure if it actually do any good at this point ?
I would not be fertilizing a weakened orchid. Fertilizer may encourage growth, but many fertilizers are high in nitrogen and you don't want more leaves that the roots can't support. I would try one of those seaweed extracts that people use to try and encourage root growth.
