Although this is ultimately a method of purchasing apples, it is often a social activity as well. Apple picking is often a very popular dating ritual in the American Midwest. Apple orchards catering to a family outing will provide additional activities beyond the picking of apples. Many have petting zoos, restaurants and country shops that sell related products such as home-made jams and jellies. This aspect of the activity is especially popular in the Northeastern United States & Southern Ontario and Southern Québec in Canada.
The apples that fall off the trees are often used to make apple cider. Apple cider is a juice made grinding the apples, then pressing out the juice.

As labor costs are still quite expensive in fruit picking, robots are being designed that can replace humans for this kind of work. The research is still in full progress, especially as the robots need to be carefully designed so that they do not bruise the fruit while picking. One solution is the use of suction grippers. Citrus fruit robot pickers have thus far been the focus of research and development, but cherry pickers are also being researched.
