Hoping to get some help regarding a broken mangrove. I have 2 in my refugium area and while I was taking it out my skimmer for cleaning I accidently snapped the top portion off. This happened a couple months ago. I was hoping it would sprout a new stem over time but that does not seem to be the case. Has anyone had this happen before? If so what do I need to do to give this the best chance of survival? It does not seem to be in too bad of shape but as the picture shows it has not shot up a new stem. Should I cut it to help with growth?
