You should used the new member/introduction forum to introduce your self.

A number of things could be going on, so digging up a few of the 'failed' suckers to inspect their roots is recommended. ... Suckers with few and/or damaged roots will show transplant stress more & longer than those with more abundant & healthy roots. It may be those suckers needed to have been culled rather than being transplanted. ... Ask a local expert for his opinion. You haven't given a lot needed detail to really answer you question.

Now I suspect (???) the dung mixture, if fresh dung was used, should not be in direct contact with the corm & roots. Place the dung mixture in the bottom of the hole then fill in & set the sucker with the natural soil.

I'm not familiar with using KMnO4, so could some of the corms or roots be damaged/burned by the solution? I think KMnO4 solutions may be much stronger than chlorine bleach solutions.

Anyway, welcome to the forum.
