Q.Splitting of quince fruits
We have had the quince tree for about 4 years with no problems in previous years. They are now ripe and at least a quarter of the crop are split. I have searched web sites but cannot find any reason for the splitting. Can you help please?
From my research I found that heavy rains just prior to ripening can cause fruit to split.
Also and in correlation with this a Fire Blight or Leaf and Fruit fungus can be the problem. Specifically the Fabraea Maculata virus can cause leaf drop and fruit disfigurement.
Here are some links for you that I found that may help you determine the cause.
