I had no time to fix a dendrobium properly in a clay pot.So I just fix it on a raw coconut husk piece and put it in a pot which is already having plants living in it.Or living the other bulbs in it. Now the new orchid is well attached to the edge of the pot and grows happily .The roots system fairly well established on the outer layer of clay pot and bloomed twice . Another factor is no coconut husk or moss fixed to the root system. wonderful growing.
