Q.Osage Orange Trees
This is the first fall ,in my 78 year old fathers memory ,that the Osage Orange Tree on his parent’s property has had basically no Osage Oranges . There have been years where there have been 5000 plus. Have you ever heard of this and do you know what could be causing this?
Osage orange is reported to have an average 75-year lifespan, although some individual trees live longer. So it could just be coming to the end of its lifespan or its fruit-producing years.
Here are some more general reasons a plant may not flower in a particular year, and thus may produce no fruit:
