English walnut early leaf & fruit drop
The large old (100 yrs?)English Walnut in our backyard is losing a lot of leaves very early this year(May) and many premature nuts as well.This is usual to some extent but seems very excessive this year.Leaves are green a bit deformed but not blackened or showing signs of common diseases,Im wondering if it may be a nutrient issue and how can you feed such a large tree?
excessive leaf loss is more likely to be a root issue rather than a nutrient deficiency. Both Phytophthora Rooot Rot and Armillaria Root Rot can affect walnut and could account for leaf loss, but it would be very helpful to see images of the tree. Can you forward a couple of pictures of the tree and the foliage directly to my email address below? Thanks!
