I wonder if it is possible to keep a normal kiwi or a hardy kiwi berry plant small, like in a bush form. I would very much like to plant some as I love the taste of kiwi, but I have no nice big south facing wall. There is only a mostly shadowy side of a shed at the border to my neighbours that would be big enough to set up a decent size trellis, but as I mentioned there is almost no direct sun. I don't have an option to set up a big structure anywhere else. So I'd like to experiment with keeping them in pots, maybe with some kind of grid to support them, but nothing too big.
Has anyone tried heavy pruning them to keep them small but still big enough for them to fruit? I'm not looking for tons of fruit, just a few nice ones to pick and eat fresh. Is there maybe even a technique, similar to what you'd do with grapes for wine production?
Also it should be possible to graft a male vine to a female, right? In order to minimize the amount of necessary plants...
