No, when picking fruit its best to pick it in the order it ripens, and as it does so, irrespective of position on the tree.

It is generally easier and requires less special equipment to pick fruit from the lower branches, hence the metaphorical description of simple tasks as low-hanging fruit. The metaphor (while it may also indicate optimal ordering for some other tasks) is not about optimal ordering for picking fruit from a tree.
