Hi there

I have a very large Spruce tree in a garden that I am looking after. The
tree has a large hole about the size of a Rugby Ball in one of the
branches.

If we have a bad storm the branch may collapse causing damage to a Tennis
Court.

The owner does not want to remove the branch, preferring to fill the hole
and wedge the branch so that it will not fall.

Would anyone be able to recommend a non-toxic tree filler and supplier?

It will not work. The branch is going to fall into the tennis court sooner
or later. Removal is the only option.
