How many years does it typically take, when started from pit/seed for a Sour Cherry tree and a Sumo Orange tree to bear fruit?

Question

This if for the San Jose/Mountain View California area, zip 94040. I understand that there may be a likely range for each of these trees and no guarantee that either will ever bear fruit. Just trying to learn if it is likely to get fruit before I die of old age.
Thanks

ps: The Sumo is growing and is a few months old. The Sour cherry pits are in the fridge chilling before planting.

Answer 1

A sour cherry tree grown from seed may take four to five years to produce, if at all. It also won't be true to the parents so you don't know what you'll get.

Sumo oranges don't typically have seeds but occasionally a bee pollination error will result in a couple seeds. They are dubbed hard to grow so good luck with this. My research showed a seed planted sumo could produce in six years.
