Anyone grows tree Tomato?


#1

My potted tree tomato grows so fast and has such big leafs. I start to feel exciting and overwhelming.

I appreciate some guidelines/tips
on
–how to over winter it inside in zone5. Does it go dormant?
–I searched the forum history and saw some people here don’t think it’s worth to grow.
I am wondering if I can graft regular tomatoes on to the tomato tree. Did Anyone try and what was the result??
It would be very cool thing to look at ( different colors, size, shape tomatoes hanging on the tree) if the answer is yes
–what a good ways to prune it?? I plan to limit it height at around 1.5~2 meter.
–any other related misc pros and cons are welcome
