Struggled with my Tokyo Sun from the beginning, was one of my first plants & I learned so much since then. The time period between the first and last photos are about 8 months!
In this case I think it was giving it time to heal and build back mostly!
When I first got it I made the mistake of adding liquid fertilizer immediately after putting it in its pot. I’m imagining there were some damaged roots during the transfer… the next day it was pretty much all dead leaves. I removed them all and that’s where the first picture was taken.
I live in Florida, so thankfully there’s plenty of sun for them. I just let it sit out in full sun since then, and watered sparingly!
