The Hardy Kiwi ‘Issai’ is a very aggressive vine. It requires a very sturdy trellis, most commonly constructed from at least four 4 x4’s for the anchor posts and 2 x 2’s as the top lattice. Also, the vine must be pruned at least yearly. The plant will take 5 years to set a decent amount of fruit. After 5 years it will be a very prolific producer of delectable large grape-sized fruits with soft edible skins that taste like the more common larger kiwis found in most grocery stores.

I got a new Issai kiwi from local nursery. All articles online say I should keep only one trunk for each plant, but I have 3 almost identical trunks from the root. Each has some smaller roots going to the soil. Should I separate it into 3 individual plants so each one will have a single trunk? If it is doable, what is the best time to do so?
