The feijoa orchard mentioned above is the Vial Family Farm (grapes are their main crop).
Seth: Do you regularly water your feijoa plants during the summer?
Are they in-ground or in pots?
What is the total bloom count in any one year?
In over 25 years, birds have only been destructive to my feijoa bush. Some tiny birds come during bloomtime and beak the fleshy petals off for a source of moisture. The whole flower is knocked to the ground in the process. Out of thousands of blooms, I am losing hundreds, not a big deal.
The most bees I have seen at that plant is about 3. In other parts of the world, blackbirds are said to be pollinators. I have never seen a robin or jay in the bush, and there are no blackbirds here.
