I'd been wondering what you'd been up to lately! What a fantastic project and beautiful iris.
I've nearly killed the first ensata seedlings I've tried to raise, so I thought I'd take a look over here at the Iris forum and see if I could find any clues. I did talk to a local ensata enthusiast and discovered that the seedlings don't like peat, but from just reading this thread it seems that mature plants at least enjoy peat in the garden. Can anyone tell me what experience they have had with ensata in pots and peat? Anyone else had ensata seedlings turn up their toes when potted in a peat-based mix?
Mine germinated in seedling trays over winter and were happy and healthy until I potted them up into seedling tubes in 50/50 peat/potting mix. I thought something that liked water-retentive acid soils would love peat! They just turned yellow and dwindled. Apparently the iris lady know had the same thing happen - she potted her first ensata seedlings into a peat-heavy mix and they died. When potted into a 'normal' open potting mix they thrived.
I can't comment from my own experience yet as I have only just removed mine from the peat and re-potted - no telling if any will survive let alone turn around and become healthy!
Paul, you're an inspiration!
