I repot my paphs after 1-1.5 years in my CHC mix, multiflorals 2-3 years. Phrags are in bark, and I repot them every 2-3 years, unless they outgrow the pot. Phrags are frequently forgotten and left in the mix for 4 years, but they seem to love wet rotten bark....I water directly into the pot....every other day for the underlights growers, once a week in winter, maybe twice a week other times, a little more in summer if its hot and windy...for paphs. Phrags are always wet, at least 5 times a week. Take care, Eric
