Thoughts on re-using bark and sphagnum ?

[Fairorchids]

This thread illustrates why I am not a fan of orchiata.

Most orchids outgrow their pot in 2-3 years.
Terry Root repotted his stud plants (Paphs) annually.

Even if the material lasts 8-10 years, what's the point?

I do exactly the same thing! I would NEVER even think of re-using bark or moss...too much risk of spreading something bad...BettyE

I agree with the above statement...I heat up the bar-b-que, and let the well rinsed LECA roast for about four hrs. at about 450 degrees. No problems, so far...BettyE

I just throw the old pot in with the new stuff (assuming the media is still good), so media that lasts 8-10 years works great for me.
