We bought this tree about 25 years ago as a sapling from Plymouth and planted it in our garden. It is now as tall as our house but as the garden slopes you could probably add another five or six foot to its growth. Since it was quite young it has produced walnuts which the local squirrels collect and store over winter. That has resulted in some unwanted saplings which we have dug up and given away. Walnuts don’t do well if their branches are cut. The sap tends to flow freely and can cause the tree to bleed sap. This can also allow infections which can damage the trees. Walnut wood is apparently very good for carpentry, but I intend to leave well alone. If it can get that big in twenty five years how big will it get in fifty…
