This time of year, the apples in Larry's yard are just starting to grow. In 4 or 5 months from now this same tree is going to have nearly 1000 apples weighing down its branches.
I think the most interesting thing about this clip is Larry saying he doesn't know much about pruning trees. This is typical of Larry's great humility. Perhaps he was never "trained" in a classroom about it, but Larry Chadwick has literally planted and grown a forest (including about a dozen huge apples trees) over the course of several decades. So...I'd say he knows more than a little about the topic.
