Q.My walnut tree doesn’t produce walnuts. How can I help it along?
I have a walnut tree with very healthy and prolific branch and leaf growth but doesn’t yet produce any walnuts unfortunately. Does it need other walnut trees nearby to fertilise it? I don’t know it’s age but it is about 4m high. Any advice would be very welcome, thanks.

Our experts say walnut trees don't start really producing until they're around ten years old. https://www.gardeningknowhow.com/edible/nut-trees/walnut/planting-walnut-trees.htm.
