Refreshing/reusing potting mix in SIP containers

luigiwu · May 28, 2015

I know potting mix can be reused for a couple of years with the proper re-supply of amendments etc. But do you find yourself coming across certain containers that are so fulll of roots that you can't use any of it at all? I'm curious about pple's experience with the earthboxes and the containers I use are 5gallon buckets.

I've also heard that most potting mix in SIP containers need to be tossed after 4 years as they stop wicking properly since the peat has broken down in that time.
