Hello! My maranta had not been doing so well and so I recently cut a branch off in hopes of creating a more resilient plant. I have chosen water propagation as this seemed to be the most recommended method, and the branch I chose had 3 fully unfurled leaves plus 1 leaf that was still in it's tube form and had not started unravelling. It has been in filtered water for just over a week, and the water has been changed twice during this time. It gets roughly 1 1/2 hours of sunlight in the morning but other that that it is next to a north facing window with lots of indirect light, I have used this particular location for the majority of my propagations in the past and they have been successful so far.
The cutting has three roots coming from one node that are each almost an inch long, however two of the fully formed leaves and the tube leaf have all crisped up and turned brown (dead) and the remaining full leaf is curling at the edges and is losing it's colour. Is this cutting a bust? Can it be saved? How do I prevent this happening in the future? The plant was a gift and so I would very much like to save it, the mother plant has two established branches left, one has 4 leaves that are not vibrant in colour but the other has 5 that have all retained their beautiful pattern and colour, but it is very leggy as leaves have dropped over winter. I was hoping for a successful propagation so I could hopefully save as much of the plant as possible.
Any help would be so appreciated, it's such a beautiful plant and we've been through a lot together!
