Just had a pop-up on my screen saying 'Win a cutting edge lawnmower'.
30 Groundforce gardens?
And if you're interested in rats you might see a few!
Looks as though you will end up with an unbalanced-looking tree when you remove this branch. The exposed interior of the trunk might not be an immediate problem - laburnums seem to survive all sorts of disasters.
To add to what I said last summer, I did own a Lawnflite, which as someone said is a Honda engine on a different deck, and it was very good - deck not quite as robust, but that made it lighter to use.
Feed them asparagus until they can't stand the smell.
I think you may be going over the top, Kevin.
Has the tear gone into the wood of the main trunk or is it only affecting the bark?
Spiraea japonica, probably Goldflame; big white daisy; some sort of mint
