I bought one of those bonsai kits from my store for 7 bucks last year. I followed the mini booklet and for a time it was growing well. End of last year toward this year Jan/Feb we had a terrible winter. I followed to what I thought would help the plant. By March into April I noticed the leaves were turning from a green to a slight brown. At that point I would transplant the sprout from the mini pot it came with to a much bigger one with new soil. I also noticed the roots of the sprout-ling one was longer than most so I trimmed the one root and replanted. Now the color of the leaves when from a brown to a now a white. (pics attached)
So have a killed my plant?
Is this normal for the mini bonsai?
