Walnut Tree, but no walnuts
We moved in to our current house a year ago, and in the back garden is a beautiful Walnut Tree, but sadly it hasn't produced any walnuts.
Speaking to our neighbour he tells us that it used to produce masses of walnuts, which fell into his garden as well. According to him the previous owners of our house had the tree cut back a couple of years back, and it hasn't produced any walnuts since.
Can it be the case, that it has reacted badly to how it was cut, or is there something else that could be wrong? It appears to be a very healthy tree, and maybe in time walnuts will return, but if it merely needs a particular nutrient, I would be very pleased to hear anyones advice.
