| Are we talking a phalaenopsis here? If so, assuming your blade was sterile or otherwise not contaminated with disease organisms, my guess is that the plant will not repair itself, but will not die either. It may stall somewhat in its growth as it works overtime to bring up nourishment through half the vascular system designed to give it life, but eventually will grow beyond the injured section to where it will not be an issue at all. You might spinkle a little cinnamon on the area as a preventative measure. |
