Shiranui grafted in September started pushing last month, including some flowers. This is on a 5g Cara Cara I purchased just as a rootstock. Since it would be fed by the nearest leaves only (yet to be fully formed), could it be allowed to hold fruit (assuming it could be secured so it wouldn't break the graft)? Or would the fruit, as a sink, retard the growth of the remaining scion buds?
Another question is how to manage the remaining nurse branches? Should I cut back progressively, proportionally to new growth, or is there some threshold of the amount of new growth when you just take them all off?
