i recently took my phals out of their bark mix and clay pots and put into sphag and plastic pots. the clay and bark was drying too quickly. now that i have potted in plastic and sphag i am having adverse conditions. the roots i believe are staying too wet. some roots look healthy while others are turning brown and shriveling. should i repot them for the second time in 4 weeks into a bark mix with the plastic pots?
