We have a small orange tree that has 2 oranges on it, and we don't know when they are ripe! We don't remember exactly when they appeared, but it was mid spring of 2006. I do know the longer grapefruit are on the tree the sweeter they are, and we were told our grapefruit is really good! (Neither one of us like them, just the tree!) We are wondering if the oranges sweeten more, too. Both trees are indoor, and we live in far north Wisconsin. They are outside during the summer, and both have now produced fruit. Any help would be much appreciated!
The answer was found in the following two documents (though one appears to be a summary of the other): References http://aggie-horticulture.tamu.edu/patiocitrus/harvesting.html http://ucce.ucdavis.edu/files/filelibrary/2193/220.htm Readers may be able give you an estimate time to maturity if you name the variety in question.
