Hello everyone.
Yesterday I saw that the future new leaf of my black cardinal (which has not unfolded for months) had a small part as if eaten, nibbled, with white residue. While looking, I saw one (only one) small yellow beast which I killed. Then I put insecticide on that area. What do you think?
I also unpotted the plant to figure out why the new leaf isn't unfolding and the roots are fine, some are a little rotten but nothing serious. I took them off.
Thanks for your help!
