English walnut still has nuts in December

Asked December 5, 2018, 11:45 PM EST

Last year I noticed a few walnuts on my tree that never fell off and this year in December it still has half of them on the tree. The shells didn’t open, just blackened and stayed on the tree. Many shells didn’t produce a nut last year. Should I be concerned?

Thank you for your question. It was referred to us in Oregon but, because there are several factors regarding English walnut production that are related to temperature, soils and pollination, I think you can obtain a more reliable answer from your own state’s Extension service. I suggest you contact them using the information at the following website: http://directory.usu.edu/department/1820/ Good luck!
