Last year we removed four badly damaged, really large black walnuts. They all put up suckers, the largest sucker is about 3 inches around already. Will these bearfruit, or do I need to remove them? I have dozens of younger walnuts, so no concern about keeping walnuts on the property, but most of the younger trees aren't masting yet
they'll bear, but it may take a couple years - should be the same nuts as the main trees before they were cut, since they're those same genetic individuals. smaller regrowth like this can be a great time to graft cultivar nuts on. i've have best luck under about 5inch diameter (at 6 or 7 feet, since i like to graft above browse level).
