Hey all, I'm here as a last ditch effort. I purchased my first outside Bonsai in June. It is a grapevine that seemed to do ok except for a little leaf burn from too much sun. I moved it to a spot that received morning sun and afternoon shade. I kept it well watered and all the leaves died over about 2 days (turned brown and dried out). I gave it some fungacide thinking it might be a fungus and then changed to a new fertilizer (5-3-3 as recommended by the company I purchased it from). This has been about 2 weeks now and I'm not seeing any new growth. Basically I have what looks like a dead grapevine in the pot.

So, is it dead? Should I try repotting it? Anything I can do at this point?

Thanks!
