Does anyone have any advice on or about VFTs and either preventing or treating rot (as in roots/bulb) when it occurs?
I ask because while there is often mention of rot or being careful with watering to avoid rotting, I find it very difficult to pin down any solid information on the actual culprit itself.
In my own experience, I have not had any -healthy- VFTs begin to rot. I have had questionable ones that ended up rotting, but one of them was plagued with powdery mildew or something similar when it arrived (Akai Ryu) and the only other victim was a very stressed looking cultivar that spent over a week in the mail (thank you, USPS ).
My healthy plants, whether I water heavily or let the trays dry up and then refill, don't ever seem to have a problem. I use a good amount of perlite, probably 50:50 at least, with sphagnum peat moss, so I do not believe that drainage was the issue with either of the two plants I've lost to rot.
Back to my original query though, does anyone have some good information on preventing rot? My experience has been specific to traumatized / unhealthy plants that succumed to rot, so if anyone has ideas on how best to nurse them to health before they rot out, I'd appreciate that as well. Also useful would be any methods you have found successful in saving a plant once rot appears to have set in on the roots or rhizome.
Thanks in advance everyone and I'm sorry if this is covered in detail somewhere else. I tried searching but did not find anything.
