I have not but I have been very interested in doing that. I have seen some interesting grass with potatoes and tomatoes together. I think it was called a ketchup and fry plant.

Yah, I was at a hydroponics outfit this spring and they had some of the tomatoes grafted to potatoes. I think they wanted like ten bucks for them. I am interested to see if a guy can get two different peppers to grow from a single plant.

Can we graft a pepper to a tomato plant. That would be cool.
I once read about a guy that grafted 10-20 different fruits to a fruit tree. He was selling those and couldnt keep up with demand.

It is common with fruit trees. I would like to see it successfully done with a couple pepper plants as well.

The tomato thing sounds interesting too.

jsschrstrchs a few years back has posted about this I remembered it being talked about not sure if they posted recently but here is the link.

What would make a better root stalk a bell pepper or a hot pepper like a habanero

I think a good rootstock would be a Tepin, as it seems to be the "mother" of the genus. They have to be tough to continue to come back year after year here in parts of Texas. Much better root system than any hybrid I've seen. Gonna try it one of these days when I find a large enough one in the wild again...

I seen one some time back. The root stock I think was called devils something. It is a winter hardy perinial it would grow peppers again the neXT year and offered great resistance to pest and disease.

Are we talking about grafting a top of one plant onto the root stock of another. I would like to see if someone has grafted a branch from one plant to another so it produces fruit from two different varieties. I know they do this with fruit trees.

The reason I brought up devils plant is because it's a perinial bush. I would think that would be the best option for multiple grafts.

Nice video. He has a followup video as well that shows the process in more detail.
