Hi, I recently bought some chinese lacebark elm seedlings online and while most of them are in good shape, 4-5 have slightly squishy roots. Two of those have visible mold/fungus. a representative picture is below.
I separated the two worst seedlings from the rest and planted them in a very well draining mix of 60% pummice, 20% perlite, and 20% soil.
I left the uppermost portions of the main tap root above the surface in hopes that it would dry out even more.
Does anyone know if fungicide would help this problem? Are there any easier solutions? Any other advice?
