These trees were used in many scenes and in many different ways in the movie, but, we only had about 35 of them, so, we had to keep re-dressing them for different scenes. That meant either removing, or putting on new leaves, apples and blossoms, not to mention constantly repairing branches, and modifying the trees to make them larger or smaller.
Here they are in the "Other World," all leafy and covered in apples.
