Cattleya orchid roots don’t grow in the potting mix
Hello,
I have multiple cattleyas and phalaenopsis, but I noticed roots of at least one cattleya hasn’t grown into the medium since repotting. Roots grew towards the medium and the end of roots became brown and stopped growing when it touched barks. It was transferred during its active growth. Most of my setups are the same including bark and sphagnum moss for all my orchids although there are some variations of the size of bark chips or the ratio of bark and sphag. I don’t fertilize until I see enough roots growing in the pot.
Now its pseudobulbs are shriveled a lot. Some aerial roots are growing well, but air is too dry here. I moved it into a setup with more sphag, but I am not sure if it will help. Does anyone know why this is happening? Thank you for your help!
