I'm also having problems with my Long Fiber Sphagnum Moss. I have it, as a top dressing, in all my vft pots and in some pots it is alive but with black burnt tips. Other pots it is green and light brown with fewer black burnt tips.
I just replaced one pot where all the LFSM had black burnt tips with new LFSM which is a beautiful light brown. Does anybody know how I can keep it this way?
Thank you in advance for any useful information.
