Hello all! I am new here and seeking to help one of my plants.

I have a persian shield, and have had it nearly a year now. When I got it, it was about 1' tall. I potted it and have it in a south facing window. The first 6 moths or so went fantastic, and it jumped up to almost 4' tall in a short amount of time, and seemed quite happy.

Over winter, it got fairly chilly (but not freezing). The leaves stopped having vibrant colors, and began to lose foliage and die back. I have heard that they do this when it gets too cold, and that cutting it back would help. I did this, and moved it further from the window to keep it warmer.

Its has been several months, and warming up more and more, and I am just beginning to get some new leaves, but they seem to be getting sad looking at the edges and dying off with some frequency. I have had no vertical growth.

All-in-all, it looks sad.
I was hoping there was something I could do to help it along. I hate to think I am killing what was once such a healthy plant.
