A very unconventional method we tried years ago after discovering I could not have my phrags sitting in trays of water because I have to keep a dehumidifer running in the fall & winter because of excess humidity in my growing area that is adjacent to my sunroom.
My husband ( he is so smart!! ) pointed out to me that using a semi hydro pot with the bark mix was the same as having the phrags sitting in trays of water. Duh ! So we started using the semi hydro pots ( 2 holes placed an inch from the bottom of a plastic pot) and our results were amazing !!
The bark does not break down any faster..I have had phrags in the same pot for 3+ years. Some phrags (the climbers) need repotting every year or so anyways. So that's our secret, but it has been told on here before, so it's really not a secret.:wink:
