Cold and wet

Next round of the pruning thing has started. Cold and wet and not time to stop and do a decent job of a blip. For those not familiar with the Bay's favourite sub tropical tree this is an avocado. In the cold and wet. Been talking with the contractor I was working with, he was telling me the current theory is that all of that fruit on the ground was a result of the freeze 5 or 6 weeks ago and there is plenty of it in the Bay of Plenty. Do you think we need some global warming?
